医用胶喷涂装置Medical glue spraying device

技术领域technical field

本申请涉及医疗器械技术领域，特别地涉及用于医用胶喷涂的医用胶喷涂装置。The present application relates to the technical field of medical devices, in particular to a medical glue spraying device used for medical glue spraying.

背景技术Background technique

在外科手术中，对生物体组织的修复经常采用缝扎操作。这种缝扎操作不仅烦琐费力，且易造成出血和新的损伤，给病人带来更多的痛苦。而且，对于那些找不到出血点的大面积渗血，传统的缝扎操作是较难处理的。医用胶的开发利用，能够克服上述缝扎操作的缺点。医用胶与传统的缝扎操作相比具有以下优点：In surgical operations, suture ligation is often used to repair biological tissue. This suture operation is not only cumbersome and laborious, but also easily causes bleeding and new injuries, which brings more pain to the patient. Moreover, for those large areas of oozing with no bleeding point, the traditional suture operation is more difficult to handle. The development and utilization of medical glue can overcome the shortcomings of the above-mentioned sewing operation. Compared with traditional suture and tying operation, medical glue has the following advantages:

i.快速止血，粘合过程没有痛苦；i. Quick hemostasis, no pain in the bonding process;

ii.无缝针缝线等异物对皮肤的刺激，减少炎症的发生，形成的瘢痕小；以及ii. The irritation of the skin by foreign bodies such as stitches and sutures reduces the occurrence of inflammation and results in small scars; and

iii.不用拆线，大大缩短就医时间，节省就医费用。iii. No need to remove sutures, which greatly shortens the time for medical treatment and saves the cost of medical treatment.

虽然医用胶有着明显的优点，但是目前医用胶的储存、喷涂等使用装置却存在着一定的不足。如图1所示，在一种医用胶喷涂装置中，将医用胶的四种基础组分分别存储在两个存储瓶10以及注射器20的两个料筒中。使用时的具体操作步骤为：Although medical glue has obvious advantages, there are certain deficiencies in the current storage and spraying devices of medical glue. As shown in FIG. 1 , in a medical glue spraying device, four basic components of medical glue are stored in two storage bottles 10 and two barrels of a syringe 20 respectively. The specific operation steps when using are:

i.取下注射器20的料筒前端的封堵件；i. Remove the blocking member at the front end of the barrel of the syringe 20;

ii.按下存储瓶10顶端的针刺，刺破存储瓶10的封装；ii. Press the needle at the top of the storage bottle 10 to pierce the packaging of the storage bottle 10;

iii.将注射器20与对应的两个存储瓶10依次接合；iii. Sequentially engaging the syringe 20 with the corresponding two storage bottles 10;

iv.抽取两个存储瓶10中的基础组分，与注射器20中的基础组分进行混匀操作；iv. Extract the basic components in the two storage bottles 10, and perform a mixing operation with the basic components in the syringe 20;

v.取下两个存储瓶10；以及v. remove the two storage bottles 10; and

vi.混匀后的注射器20与喷头30结合进行喷涂工作。vi. The mixed syringe 20 is combined with the spray head 30 for spraying.

由此可以看出，现有的医用胶喷涂装置的方案用于完成存储基础组分、混匀基础组分与喷涂医用胶的操作的零部件较多，其带来的直接缺点就是操作步骤较为繁琐，耗时较长。而且，在吸取存储瓶10中的基础组分时，会因为基础组分粘留在瓶壁、管路中等原因造成原始设定的基础组分比例发生变化，进而直接影响交联成胶的效果。It can be seen from this that the existing solution of the medical glue spraying device has many parts for storing the basic components, mixing the basic components and spraying the medical glue, and the direct disadvantage is that the operation steps are relatively complicated. Cumbersome and time-consuming. Moreover, when the basic components in the storage bottle 10 are sucked, the originally set basic component ratio will change due to the basic components sticking to the bottle wall and pipeline, etc., which will directly affect the effect of cross-linking and forming glue. .

Parts of the two

syringes

syringes

1a, 1b are in controlled communication with the flow path of the spray head 2 .

在本实施例中，两个注射器1a、1b具有相同的结构，以下采用第一注射器1a为例说明注射器的结构。如图2B至图2E所示，第一注射器1a包括组装在一起的料筒11、操作杆12、操作板13、活塞14、第一阀15、第二阀16和封堵件17。In this embodiment, the two

syringes

1a and 1b have the same structure, and the structure of the syringe is described below by taking the first syringe 1a as an example. As shown in FIGS. 2B to 2E , the first syringe 1 a includes a cartridge 11 , an operating rod 12 , an operating plate 13 , a piston 14 , a first valve 15 , a second valve 16 and a blocking member 17 assembled together.

在本实施例中，如图2B至图2E所示，料筒11形成有沿着轴向A贯通的圆筒形状，料筒11各部分的内径可以根据需要进行改变。料筒11的轴向一侧端部(图2B至图2E的上端部)形成有第一开口，第一开口作为***安装活塞14等的安装口。料筒11的轴向另一侧端部(图2B至图2E的下端部)形成有第二开口，第二开口作为医用胶的基础组分流出的出液口。In this embodiment, as shown in FIGS. 2B to 2E , the barrel 11 is formed in a cylindrical shape that penetrates along the axial direction A, and the inner diameter of each part of the barrel 11 can be changed as required. A first opening is formed at one end portion in the axial direction of the cartridge 11 (the upper end portion in FIGS. 2B to 2E ), and the first opening serves as a mounting port for inserting and mounting the piston 14 and the like. The other axial end of the cartridge 11 (the lower end in FIG. 2B to FIG. 2E ) is formed with a second opening, and the second opening serves as a liquid outlet from which the basic components of the medical glue flow out.

在本实施例中，如图2B至图2E所示，操作杆12具有沿着轴向A直线状延伸的长杆形状，操作杆12与料筒11同轴配置，操作杆12的一部分***料筒11的内部。具体地，操作杆12的轴向一侧端部位于料筒11的外部，并且与操作板13固定。操作杆12的轴向另一侧端部与封堵件17固定在一起，封堵件17与位于料筒11内的活塞14固定在一起。这样，能够通过对操作板13施力来控制操作杆12的运动，由此通过操作杆12带动活塞14在料筒11内部相对于料筒11沿着轴向A能够往复运动。In this embodiment, as shown in FIGS. 2B to 2E , the operating rod 12 has a long rod shape extending linearly along the axial direction A, the operating rod 12 is coaxially arranged with the cartridge 11 , and a part of the operating rod 12 is inserted into the material inside of the barrel 11 . Specifically, the axial one-side end portion of the operating rod 12 is located outside the cartridge 11 and is fixed to the operating plate 13 . The other axial end of the operating rod 12 is fixed with a blocking member 17 , and the blocking member 17 is fixed with the piston 14 located in the cartridge 11 . In this way, the movement of the operating rod 12 can be controlled by applying force to the operating plate 13 , so that the operating rod 12 drives the piston 14 to reciprocate relative to the barrel 11 along the axial direction A inside the barrel 11 .

在本实施例中，如图2B所示，操作板13具有平板形状，操作板13以与轴向A垂直的方式与操作杆12的轴向一侧端部固定。两个注射器1a、1b的操作板13可以是一体的，也可以是分开的。操作板13用于可以与其它动力组件(参见第七实施例)固定或者用于手持作业。这样可以使得两个注射器1a、1b的操作杆12的抽拉和推送操作更方便快捷。In this embodiment, as shown in FIG. 2B , the operation plate 13 has a flat plate shape, and the operation plate 13 is fixed to one end portion in the axial direction of the operation lever 12 so as to be perpendicular to the axial direction A. As shown in FIG. The operation panels 13 of the two

syringes

1a, 1b may be integrated or separate. The operation panel 13 can be fixed with other power components (see the seventh embodiment) or used for hand-held operation. This can make the pulling and pushing operations of the operating rods 12 of the two

syringes

1a, 1b more convenient and quicker.

在本实施例中，如图2B至图2E所示，活塞14形成为带底部的圆筒状(截面为大致U型)，底部位于活塞14的轴向另一侧端部，并且活塞14以与料筒11同轴的方式收纳在料筒11的内部。活塞14的外周壁与料筒11的内周壁彼此接触，以使得活塞14和料筒11之间实现密封。活塞14的轴向一侧端部通过封堵件17与操作杆12的轴向另一侧端部固定，封堵件17还使得活塞14的轴向一侧端部处的开口关闭。In the present embodiment, as shown in FIGS. 2B to 2E , the piston 14 is formed in a cylindrical shape with a bottom (substantially U-shaped in cross section), and the bottom is located at the other end of the piston 14 in the axial direction, and the piston 14 is formed with It is accommodated inside the cartridge 11 so as to be coaxial with the cartridge 11 . The outer peripheral wall of the piston 14 and the inner peripheral wall of the cartridge 11 are in contact with each other, so that sealing is achieved between the piston 14 and the cartridge 11 . One axial end of the piston 14 is fixed to the other axial end of the operating rod 12 by a blocking member 17 which also closes the opening at the axial one end of the piston 14 .

在本实施例中，如图2B至图2E所示，第一阀15设置在活塞14的底部的开口处，用于控制该开口的开闭，进而控制第一注射器1a的第一储存室S1和第二储存室S2之间的连通和断开。如图2F和图2G所示，第一阀15包括阀体151、限位台152和阀芯挡片153。阀体151可以与活塞14以同轴的方式形成为一体，阀体151的内部形成有与活塞14的内部连通的通道。阀体151在其轴向另一侧端部的开口处形成有朝向所述通道的内部凸出的凸缘部151f。限位台152位于阀体151的内部，限位台152的外周面与阀体151的内周面抵接，使得限位台152与阀体151之间实现密封。限位台152在轴向A上与凸缘部151f相对。阀芯挡片153为弹性挡片，阀芯挡片153一部分被夹固定在凸缘部151f和限位台152之间，阀芯挡片153的另一部分在无外力的情况下抵靠限位台152，且阀芯挡片153的另一部分与凸缘部151f间隔开足够的距离。这样，当阀芯挡片153的两侧的压力相等或者阀芯挡片153的轴向一侧(图2F中的上侧)的压力小于轴向另一侧(图2F中的下侧)的压力时，阀芯挡片153处于如图2F所示的关闭状态，此时阀芯挡片153关闭阀体151内的通道；当阀芯挡片153由于其轴向一侧(图2G中的上侧)的压力大于其轴向另一侧(图2G中的下侧)的压力而处于如图2G所示的打开状态时，阀芯挡片153的另一部分翘起而与限位台152间隔开，从而使得阀体151内的通道开放。In this embodiment, as shown in FIG. 2B to FIG. 2E , the first valve 15 is disposed at the opening of the bottom of the piston 14 to control the opening and closing of the opening, thereby controlling the first storage chamber S1 of the first syringe 1a The connection and disconnection between the second storage chamber S2. As shown in FIGS. 2F and 2G , the first valve 15 includes a valve body 151 , a limit stand 152 and a valve core blocking piece 153 . The valve body 151 may be integrally formed with the piston 14 in a coaxial manner, and a passage communicating with the interior of the piston 14 is formed inside the valve body 151 . The valve body 151 is formed with a flange portion 151f protruding toward the inside of the passage at the opening of the end portion on the other side in the axial direction. The limiting platform 152 is located inside the valve body 151 , and the outer peripheral surface of the limiting platform 152 is in contact with the inner peripheral surface of the valve body 151 , so that the limiting platform 152 and the valve body 151 are sealed. The stopper 152 faces the flange portion 151f in the axial direction A. As shown in FIG. The valve core blocking piece 153 is an elastic blocking piece, a part of the valve core blocking piece 153 is clamped and fixed between the flange part 151f and the limit table 152 , and the other part of the valve core blocking piece 153 abuts against the limit without external force The stage 152 is installed, and the other part of the spool stopper 153 is spaced apart from the flange portion 151f by a sufficient distance. In this way, when the pressures on both sides of the valve core stopper 153 are equal or the pressure on one axial side (upper side in FIG. 2F ) of the valve core stopper 153 is smaller than that on the other axial side (lower side in FIG. 2F ) When the pressure is applied, the valve core stopper 153 is in the closed state as shown in FIG. 2F, at this time, the valve core stopper 153 closes the passage in the valve body 151; When the pressure on the upper side) is greater than the pressure on the other side of the axial direction (the lower side in FIG. 2G ), and in the open state as shown in FIG. spaced so that the passages within the valve body 151 are open.

可以理解，凸缘部151f可以在对应阀芯挡片153的另一部分的位置形成缺口，从而避免在阀芯挡片153的另一部分翘起时与凸缘部151f发生干涉而影响阀体151内通道的开放。It can be understood that the flange portion 151f may form a notch at a position corresponding to another part of the valve core blocking piece 153 , so as to avoid interference with the flange portion 151f when the other part of the valve core blocking piece 153 is lifted and affecting the inside of the valve body 151 opening of the channel.

在本实施例中，如图2B至图2E所示，第二阀16设置在料筒11的轴向另一侧的第二开口处。第二阀16可以具有与第一阀15相同的结构，第二阀16能够控制第二开口的开闭，从而控制第一注射器1a中的第二储存室S2与喷头2的流路的连通和断开。In the present embodiment, as shown in FIGS. 2B to 2E , the second valve 16 is provided at the second opening on the other side in the axial direction of the cartridge 11 . The second valve 16 may have the same structure as the first valve 15 , and the second valve 16 can control the opening and closing of the second opening, thereby controlling the communication and communication between the second storage chamber S2 in the first syringe 1a and the flow path of the spray head 2 . disconnect.

这样，只是通过抽拉和推送操作杆12就可以实现第一阀15和第二阀16的打开和关闭，进而完成两种不同基础组分的混合以及混合好的基础组分的送出，操作极其简单，极大的节约了操作时间。In this way, the opening and closing of the first valve 15 and the second valve 16 can be realized only by pulling and pushing the operating rod 12, thereby completing the mixing of two different basic components and the delivery of the mixed basic components. The operation is extremely Simple, greatly saves operating time.

通过采用上述结构的注射器1a、1b，由活塞14、第一阀15和封堵件17包围形成第一储存室S1，由料筒11、活塞14、第一阀15和第二阀16包围形成第二储存室S2。这样，由于第二注射器1b具有与第一注射器1a相同的结构，因而在本申请的医用胶喷涂装置中，第一注射器1a和第二注射器1b两者共形成了四个储存室，用于将医用胶的各基础组分分开封装。医用胶一般包括四种基础组分，本申请的结构设计能够通过预灌注将四种基础组分分开存储在同一医用胶喷涂装置的两个注射器1a、1b之内，需要使用时再将各基础组分混合交联成胶。By adopting the

syringes

1a and 1b of the above structure, the first storage chamber S1 is formed by being surrounded by the piston 14 , the first valve 15 and the blocking member 17 , and the first storage chamber S1 is formed by being surrounded by the cartridge 11 , the piston 14 , the first valve 15 and the second valve 16 . The second storage chamber S2. In this way, since the second syringe 1b has the same structure as the first syringe 1a, in the medical glue spraying device of the present application, the first syringe 1a and the second syringe 1b form a total of four storage chambers for the The basic components of the medical glue are packaged separately. Medical glue generally includes four basic components. The structural design of this application can store the four basic components separately in the two

syringes

1a and 1b of the same medical glue spraying device through pre-infusion. The components are mixed and cross-linked to form a gel.

以下说明第一实施例的医用胶喷涂装置的注射器1a、1b在使用时的工作过程。The following describes the working process of the

syringes

1a and 1b of the medical glue spraying device of the first embodiment in use.

当处于未工作的初始状态时，第一注射器1a和第二注射器1b都处于如图2C所示的状态。第一阀15和第二阀16处于关闭状态，使得第一储存室S1和第二储存室S2以及第二储存室S2和喷头2的流路均不连通，两个注射器1a、1b的不同储存室S1、S2的内部存储医用胶的不同基础组分。使用时通过操作板13抽拉操作杆12，带动整个第一储存室S1向远离喷头2的方向移动，使得第二储存室S2的容积增大且内部压力减小，而第一储存室S1的内部压力不变，第一储存室S1的内部压力大于第二储存室S2的内部压力，产生的内部压力差使得第一阀15处于打开状态，第一储存室S1内的基础组分流入第二储存室S2，并与储存在第二储存室S2内的另一种基础组分混合。之后，注射器处于如图2D所示的中间状态，第二储存室S2的容积变成最大。推动操作杆12，带动整个第一储存室S1向喷头2方向移动，第二储存室S2的内部压力增大，使得第一阀15关闭并且第二阀16打开，两个注射器1a、1b内混合完成的基础组分将流入喷头2内完成混合交联，之后喷出。When in the initial state of non-operation, both the first syringe 1a and the second syringe 1b are in the state shown in FIG. 2C. The first valve 15 and the second valve 16 are in a closed state, so that the first storage chamber S1 and the second storage chamber S2 and the flow paths of the second storage chamber S2 and the spray head 2 are not connected, and the two

syringes

1a and 1b are stored differently. The interior of the chambers S1, S2 stores the different base components of the medical glue. During use, the operating rod 12 is pulled through the operating panel 13 to drive the entire first storage chamber S1 to move away from the spray head 2, so that the volume of the second storage chamber S2 increases and the internal pressure decreases, while the first storage chamber S1 The internal pressure remains unchanged, the internal pressure of the first storage chamber S1 is greater than the internal pressure of the second storage chamber S2, and the resulting internal pressure difference makes the first valve 15 open, and the basic components in the first storage chamber S1 flow into the second storage chamber S1. storage chamber S2, and mixed with another base component stored in the second storage chamber S2. After that, the syringe is in an intermediate state as shown in FIG. 2D, and the volume of the second storage chamber S2 becomes the maximum. Push the operating rod 12 to drive the entire first storage chamber S1 to move toward the spray head 2, and the internal pressure of the second storage chamber S2 increases, so that the first valve 15 is closed and the second valve 16 is opened, and the two

syringes

1a and 1b are mixed in The completed base component will flow into the spray head 2 to complete the mixing and cross-linking, and then spray out.

在本实施例中，如图2B所示，喷头2包括组装在一起的主体21和进气管22。In this embodiment, as shown in FIG. 2B , the spray head 2 includes a main body 21 and an air intake pipe 22 assembled together.

主体21的内部形成有彼此连通的第一流路21a、第二流路21b和公共流路21c。第一流路21a与第一注射器1a的轴向另一侧端部相连，通过第一注射器1a的第二阀16控制第一流路21a与第一注射器1a的第二储存室S2的连通和断开。第二流路21b与第二注射器1b的轴向另一侧端部相连，通过第二注射器1b的第二阀16控制第二流路21b与第二注射器1b的第二储存室S2的连通和断开。第一流路21a和第二流路21b在喷头2内倾斜地延伸，与公共流路21c在同一部位交汇连通。从第一注射器1a的第二储存室S2流出然后流经第一流路21a的基础组分与从第二注射器1b的第二储存室S2流出然后流经第二流路21b的基础组分在公共流路21c处混合交联，然后经由公共流路21c喷出。The inside of the main body 21 is formed with a first flow path 21a, a second flow path 21b, and a common flow path 21c that communicate with each other. The first flow path 21a is connected to the other end in the axial direction of the first syringe 1a, and the communication and disconnection between the first flow path 21a and the second storage chamber S2 of the first syringe 1a are controlled by the second valve 16 of the first syringe 1a. . The second flow path 21b is connected to the other end in the axial direction of the second syringe 1b, and the communication between the second flow path 21b and the second storage chamber S2 of the second syringe 1b is controlled by the second valve 16 of the second syringe 1b. disconnect. The first flow path 21a and the second flow path 21b extend obliquely in the shower head 2, and communicate with the common flow path 21c at the same location. The base component that flows out of the second storage chamber S2 of the first syringe 1a and then flows through the first flow path 21a is in common with the base component that flows out of the second storage chamber S2 of the second syringe 1b and then flows through the second flow path 21b Mixed and cross-linked at the flow path 21c, and then ejected through the common flow path 21c.

进气管22为绝缘管。进气管22的轴向一侧端部与送气单元相连，进气管22的轴向另一侧端部与第一流路21a、第二流路21b和公共流路21c三者的交汇部位连通。并且，进气管22与公共流路21c在轴向A上相对。The intake pipe 22 is an insulating pipe. One axial end of the intake pipe 22 is connected to the air supply unit, and the other axial end of the intake pipe 22 is communicated with the intersection of the first flow path 21a, the second flow path 21b and the common flow path 21c. In addition, the intake pipe 22 faces the common flow path 21c in the axial direction A. As shown in FIG.

在本实施例中，如图2A所示，壳体3主要用于支撑固定两个注射器1a、1b、喷头2、送气单元和静电单元，以用于保证这些部件的稳定工作以及对这些部件起到良好的保护作用。壳体3的形状可以根据需要进行改变。In this embodiment, as shown in FIG. 2A , the housing 3 is mainly used to support and fix the two

syringes

1a, 1b, the spray head 2, the air supply unit and the electrostatic unit, so as to ensure the stable operation of these components and to support these components. to good protection. The shape of the housing 3 can be changed as required.

在本实施例中，如图2B所示，送气单元(图中未示出，可以包括泵等部件)能够通过进气管22向公共流路21c内输送高压气体，用于对公共流路21c内已经混合交联的医用胶进行初步吹散。如图2B所示，静电单元包括负离子发生器4，负离子发生器4设在进气管22中。负离子发生器4通电之后能够产生负离子，进而对送气单元输送进入进气管22的高压气体进行净化杀菌，避免污染喷头2内的医用胶。负离子发生器4产生负离子的同时还可以产生高压静电，在喷头2内部的流路中形成高压电场，将空气电离，经高压气体初步打散后的医用胶液滴在通过高压电场后被带上静电电荷，因为同种电荷相斥，医用胶液滴会进一步破碎实现雾化，分散地更加均匀。In this embodiment, as shown in FIG. 2B , the air supply unit (not shown in the figure, may include a pump and other components) can send high-pressure gas into the common flow path 21c through the air inlet pipe 22, for the purpose of supplying air to the common flow path 21c. The medical glue that has been mixed and cross-linked is initially blown out. As shown in FIG. 2B , the electrostatic unit includes a negative ion generator 4 , and the negative ion generator 4 is provided in the air intake pipe 22 . After the negative ion generator 4 is energized, negative ions can be generated, so as to purify and sterilize the high-pressure gas transported by the air supply unit into the air intake pipe 22 to avoid contaminating the medical glue in the nozzle 2 . The negative ion generator 4 can also generate high-voltage static electricity while generating negative ions, forming a high-voltage electric field in the flow path inside the nozzle 2 to ionize the air. Electrostatic charge, because of the repulsion of the same charge, the medical glue droplets will be further broken to achieve atomization, and the dispersion will be more uniform.

这样，将四种基础组分混合交联最终形成医用胶，混合更加均匀，成胶效果更好。另外，医用胶的所有基础组分都已经预先储存在了第一注射器1a和第二注射器1b中，不需要其它附加的存储工具因而不再进行吸取转移，可以避免吸取转移过程中由于基础组分粘留或损失而造成的原始设定的基础组分比例发生变化的问题。第一注射器1a和第二注射器1b与喷头2可以设置成一体的，就避免了拆卸安装操作的步骤，简化了操作。同时送气单元产生的高压气体能够将混合交联后的组分初步吹散，再经过静电单元的作用后雾化为更小的液滴，经喷头2均匀喷出。In this way, the four basic components are mixed and cross-linked to finally form a medical glue, the mixing is more uniform, and the glue forming effect is better. In addition, all the basic components of the medical glue have been pre-stored in the first syringe 1a and the second syringe 1b, and no other additional storage tools are required, so the transfer is no longer performed, which can avoid the need for the basic components during the transfer process. The problem of changes in the proportions of the base components that were originally set due to sticking or loss. The first injector 1a, the second injector 1b and the spray head 2 can be integrated into one piece, which avoids the steps of disassembly and installation, and simplifies the operation. At the same time, the high-pressure gas generated by the air supply unit can initially blow up the mixed and cross-linked components, and then atomized into smaller droplets through the action of the electrostatic unit, which are sprayed uniformly through the nozzle 2 .

另外，如图2H所示，在第一注射器1a和第二注射器1b两者的料筒1的远离喷头2开口端部处，设有与料筒1形成为一体的夹持凸缘7。这样可以使得第一注射器1a和第二注射器1b的操作杆的抽拉和推送操作更方便快捷，方便进行手持作业。In addition, as shown in FIG. 2H , at the ends of the barrels 1 of both the first syringe 1 a and the second syringe 1 b away from the opening end of the spray head 2 , a clamping flange 7 integrally formed with the barrel 1 is provided. In this way, the pulling and pushing operations of the operating rods of the first syringe 1a and the second syringe 1b can be more convenient and quicker, and the hand-held operation is convenient.

The other axial end of the operating rod 12 passes through the blocking member 17 , extends into the barrel 11 and is fixedly connected to the piston 14 . The blocking member 17 is fixedly installed at the opening of the axial end of the barrel 11, and the opening of the barrel 11 is semi-closed; the spring bottle 19 is accommodated in the barrel 11 and is located between the piston 14 and the blocking member 17, The spring bottle 19 can expand and contract in the axial direction A, thereby changing the size of the inner space of the spring bottle 19, and the outer wall of the spring bottle 19 can fit with the inner wall of the operating rod 12, so that the operating rod 12 can be pushed and pulled to change the spring bottle 19 The opening of the spring bottle 19 toward the direction of the piston 14 is connected with the first valve 15 , so that the opening and closing of the opening of the spring bottle 19 is controlled by the first valve 15 .

以下说明第四实施例的医用胶喷涂装置的注射器1a、1b在使用时的工作过程。The following describes the working process of the

syringes

处于未工作的初始状态时，第一注射器1a和第二注射器1b都处于如图5A所示的状态。第一阀15和第二阀16处于关闭状态，使得第一储存室S1和第二储存室S2以及第二储存室S2和喷头2的流路均不连通，两个注射器1a、1b的不同储存室S1、S2的内部存储医用胶的不同基础组分。使用时，通过拉动操作杆12，能够带动活塞14向远离喷头2的方向移动，使得弹簧瓶19受压之后第一储存室S1的容积减小且内部压力增大，同时第二储存室S2的容积增大且内部压力减小，第一储存室S1的内部压力大于第二储存室S2的内部压力，产生的内部压力差使得第一阀15处于打开状态，第一储存室S1内的基础组分流入第二储存室S2，并与储存在第二储存室S2内的另一种基础组分混合。之后，注射器1a、1b处于如图5B所示的中间状态，第一储存室S1的容积基本变为零，且第二储存室S2的容积变成最大。推动操作杆12，带动活塞14和弹簧瓶19朝向喷头2移动，第二储存室S2的内部压力增大，使得第一阀15关闭并且第二阀16打开，两个注射器内混合完成的基础组分将流入喷头2内完成混合交联，之后喷出。In the initial state of non-operation, both the first syringe 1a and the second syringe 1b are in the state shown in FIG. 5A . The first valve 15 and the second valve 16 are in a closed state, so that the first storage chamber S1 and the second storage chamber S2 and the flow paths of the second storage chamber S2 and the spray head 2 are not connected, and the two

syringes

1a and 1b are stored differently. The interior of the chambers S1, S2 stores the different base components of the medical glue. During use, by pulling the operating rod 12, the piston 14 can be driven to move away from the spray head 2, so that after the spring bottle 19 is pressurized, the volume of the first storage chamber S1 decreases and the internal pressure increases, while the The volume increases and the internal pressure decreases, the internal pressure of the first storage chamber S1 is greater than the internal pressure of the second storage chamber S2, and the resulting internal pressure difference makes the first valve 15 in an open state, and the basic group in the first storage chamber S1 Diverted into the second storage chamber S2 and mixed with another base component stored in the second storage chamber S2.

syringes

1a, 1b are in an intermediate state as shown in FIG. 5B, the volume of the first storage chamber S1 becomes substantially zero, and the volume of the second storage chamber S2 becomes the maximum. Push the operating rod 12 to drive the piston 14 and the spring bottle 19 to move toward the spray head 2, the internal pressure of the second storage chamber S2 increases, so that the first valve 15 is closed and the second valve 16 is opened, and the two syringes are mixed. The components will flow into the nozzle 2 to complete the mixing and cross-linking, and then discharge.

在本实施例中，由于第一储存室S1是由弹簧瓶19和第一阀15包围形成，所以封堵件17与料筒11之间的连接以及封堵件17与操作杆12之间密封性的要求就没有那么高，只需要保证弹簧瓶19的开口与第一阀15的连接具有良好的密封性即可。In this embodiment, since the first storage chamber S1 is surrounded by the spring bottle 19 and the first valve 15 , the connection between the blocking member 17 and the cartridge 11 and the sealing between the blocking member 17 and the operating rod 12 are sealed The requirements for performance are not so high, and it is only necessary to ensure that the connection between the opening of the spring bottle 19 and the first valve 15 has good sealing performance.

(根据本申请的第五实施例的医用胶喷涂装置的结构及工作过程)(The structure and working process of the medical glue spraying device according to the fifth embodiment of the present application)

第五实施例的医用胶喷涂装置的结构与第一实施例的医用胶喷涂装置的结构基本相同，以下主要说明两者之间的不同之处。The structure of the medical glue spraying device of the fifth embodiment is basically the same as that of the medical glue spraying device of the first embodiment, and the following mainly describes the differences between the two.

在本实施例中，两个注射器1a、1b具有相同的结构，以下采用第一注射器1a为例说明注射器的结构。具体地，如图6A至图6C所示，第一注射器1a包括组装在一起的料筒11、操作杆12、活塞14、第一阀15’、第二阀16、封堵件17和柔性连接件110。In this embodiment, the two

syringes

1a and 1b have the same structure, and the structure of the syringe is described below by taking the first syringe 1a as an example. Specifically, as shown in FIGS. 6A to 6C , the first syringe 1a includes a cartridge 11 , an operating rod 12 , a piston 14 , a first valve 15 ′, a second valve 16 , a blocking member 17 and a flexible connection assembled together Piece 110.

在本实施例中，如图6A至图6C所示，料筒11、操作杆12、活塞14、第二阀16、封堵件17与第一实施例中的相应结构基本相同。活塞14底部设有连通第一储存室S1和第二储存室S2的开口，第一阀15’设置在活塞14的底部的下方，用于控制活塞14的开口的开闭。如图6D所示，第一阀15’包括形成为一体的圆环部151’、辐条152’和柱塞153’。圆环部151’沿着料筒11的周向在整周上连续地延伸，圆环部151’的外径与料筒11的内径匹配。四根辐条152’在周向上均匀分布，每根辐条152’沿着料筒11的径向延伸且用于连接圆环部151’和柱塞153’。柱塞153’与圆环部151’同轴地配置，柱塞153’的外径与活塞14的开口的内径匹配。这样，当柱塞153’***活塞14的开口时，柱塞153’关闭该开口。此外，柔性连接件110可以是由塑料制成的细线，第一阀15’通过柔性连接件110与料筒11的靠轴向另一侧端部处的部分相连。In this embodiment, as shown in FIGS. 6A to 6C , the barrel 11 , the operating rod 12 , the piston 14 , the second valve 16 , and the blocking member 17 are basically the same as those in the first embodiment. The bottom of the piston 14 is provided with an opening communicating with the first storage chamber S1 and the second storage chamber S2, and the first valve 15' is arranged below the bottom of the piston 14 for controlling the opening and closing of the opening of the piston 14. As shown in Fig. 6D, the first valve 15' includes an integrally formed annular portion 151', spokes 152' and a plunger 153'. The annular portion 151' extends continuously over the entire circumference along the circumferential direction of the barrel 11, and the outer diameter of the annular portion 151' matches the inner diameter of the barrel 11. The four spokes 152' are evenly distributed in the circumferential direction, and each spoke 152' extends along the radial direction of the barrel 11 and is used to connect the annular portion 151' and the plunger 153'. The plunger 153' is arranged coaxially with the annular portion 151', and the outer diameter of the plunger 153' matches the inner diameter of the opening of the piston 14. In this way, when the plunger 153' is inserted into the opening of the piston 14, the plunger 153' closes the opening. In addition, the flexible connecting member 110 may be a thin wire made of plastic, and the first valve 15' is connected to a portion of the cartridge 11 at the end on the other side in the axial direction through the flexible connecting member 110.

通过采用上述结构的注射器1a、1b，由活塞14、第一阀15’和封堵件17包围形成第一储存室S1，由料筒11、活塞14、第一阀15’和第二阀16包围形成第二储存室S2。By adopting the

syringes

1a and 1b of the above structure, a first storage chamber S1 is formed surrounded by the piston 14 , the first valve 15 ′ and the blocking member 17 , and the first storage chamber S1 is formed by the cylinder 11 , the piston 14 , the first valve 15 ′ and the second valve 16 . The second storage chamber S2 is formed around it.

以下说明第五实施例的医用胶喷涂装置的注射器1a、1b在使用时的工作过程。The following describes the working process of the

syringes

1a and 1b of the medical glue spraying device of the fifth embodiment during use.

处于未工作的初始状态时，第一注射器1a和第二注射器1b都处于如图6A所示的状态。第一阀15’的柱塞153’关闭活塞14的开口，使得第一储存室S1和第二储存室S2不连通，第二阀16关闭料筒11的轴向另一侧端部处的开口，使得第二储存室S2和喷头2的流路不连通，两个注射器1a、1b的不同储存室的内部存储医用胶的不同基础组分。此时，柔性连接件110处于松弛状态。使用时，通过拉动操作杆12，带动封堵件17和活塞14向远离喷头2的方向移动。在上述过程中，第一阀15’先随着活塞14朝向远离喷头2的方向移动，直至柔性连接件110绷紧之后，第一阀15’的移动受到柔性连接件110的制约使得第一阀15’与活塞14分离(如图6B所示)。由此，活塞14的开口处于打开状态，第一储存室S1内的基础组分经由活塞14的开口以及第一阀15’的辐条152’之间的间隙流入第二储存室S2，并与储存在第二储存室S2内的另一种基础组分混合。之后，注射器1a、1b处于如图6B所示的中间状态，第一储存室S1和第二储存室S2彼此连通。设计时，可以让第一阀15’的圆环部151’的外周面与料筒11的内壁面之间存在一定的摩擦力，柱塞153’与活塞14的开口的侧壁之间也存在一定的摩擦力，并且柱塞153’与活塞14的开口的侧壁之间的摩擦力要大于圆环部151’的外周面与料筒11的内壁面之间的摩擦力，这样既可以保证第一阀15’能够跟随活塞14一起移动，又可以保证在第一阀15’与活塞14脱开之后其还能够停留在料筒11的预定位置处。第一储存室S1中的基础组分全部流入到第二储存室S2中后，推动操作杆12，如图6C所示，活塞14的底壁首先与第一阀15’接触，继续推送操作杆12，在圆环部151’的外周面与料筒11内壁面之间的摩擦力以及第二储存室S2中的压力作用下，第一阀15’的柱塞153’又***到活塞14的开口中将其关闭，继续推送操作杆12，就会使得第二储存室S2中的压力上升，在第二储存室S2中的压力增大到大于料筒11外界压力之后，第二阀16就会打开，之后喷出。In the initial state of non-operation, both the first syringe 1a and the second syringe 1b are in the state shown in FIG. 6A . The plunger 153 ′ of the first valve 15 ′ closes the opening of the piston 14 so that the first storage chamber S1 and the second storage chamber S2 are not communicated, and the second valve 16 closes the opening at the other end of the cartridge 11 in the axial direction , so that the flow paths of the second storage chamber S2 and the spray head 2 are not communicated, and different basic components of the medical glue are stored in the different storage chambers of the two

syringes

1a and 1b. At this time, the flexible connector 110 is in a relaxed state. During use, by pulling the operating rod 12 , the blocking member 17 and the piston 14 are driven to move away from the spray head 2 . In the above process, the first valve 15' first moves away from the spray head 2 along with the piston 14, until the flexible connecting member 110 is tightened, the movement of the first valve 15' is restricted by the flexible connecting member 110, so that the first valve 15' is separated from piston 14 (as shown in Figure 6B). As a result, the opening of the piston 14 is in an open state, and the basic components in the first storage chamber S1 flow into the second storage chamber S2 through the opening of the piston 14 and the gap between the spokes 152' of the first valve 15', and are connected with the storage chamber S2. Another base component is mixed in the second storage chamber S2. After that, the

The generator The voltage of the low-voltage power supply is converted into high-voltage electricity of 1000 volts to 7000 volts, and the generator transmits the high-voltage electricity to the conductor 24, so as to form a high-voltage electric field near the conductor 24, and then ionize the air in the outlet flow channel 23a. The medical glue droplets that have been initially dispersed by the gas are charged with electrostatic charges after passing through the high-voltage electric field. Because of the repulsion of the same charge, the medical glue droplets will be further broken to achieve further atomization, and the dispersion will be more uniform. Thus, compared with the first embodiment, the negative ion generator 4 can be omitted from the air intake pipe 22 of the shower head 2 .

如图8A和图8B所示，除了包括与第一实施例相同的结构之外，在本实施例中，医用胶喷涂装置还包括动力组件5和自适应幅宽调节组件6。动力组件5能够带动操作板13和操作杆12运动，将两注射器1a、1b中的医用胶的基本组分输送到喷头2中。自适应幅宽调节组件6能够根据喷头2与待喷涂对象的目标喷涂区域之间的距离来自适应调整喷头2喷出的幅宽，如此就可以实现在手持设备上下晃动、伤口高低不平的条件下稳定的喷涂设定幅宽的医用胶，而且喷涂过程是全自动进行。As shown in FIGS. 8A and 8B , in addition to including the same structure as the first embodiment, in this embodiment, the medical glue spraying device further includes a power assembly 5 and an adaptive width adjustment assembly 6 . The power assembly 5 can drive the operation panel 13 and the operation rod 12 to move, and deliver the basic components of the medical glue in the two

syringes

1 a and 1 b to the spray head 2 . The adaptive width adjustment component 6 can adaptively adjust the width of the spray nozzle 2 according to the distance between the nozzle 2 and the target spraying area of the object to be sprayed, so that the hand-held device can be shaken up and down and the wound is uneven. Stable spraying of medical glue with a set width, and the spraying process is fully automatic.

具体地，如图8B所示，动力组件5用于驱动注射器的操作板13，使得操作杆12在注射器的料筒11内进行直线运动。动力组件5包括组装在一起的电机51、丝杠52、滑块53和连接件54。丝杠52整体沿着轴向A延伸，丝杠52与电机51的输出轴连接，丝杠52能够被电机51驱动。滑块53套设于丝杠52上并能够经由丝杠52将电机51的转动转换为直线运动。通过连接件54，使得滑块53与两个注射器1a、1b的操作板13连接。通过控制电机51沿着不同旋转方向旋转，进而就可以控制与滑块53相连接的操作板13前进与后退，也即使得与操作板13相连的操作杆12在注射器的料筒11内抽拉和推送。Specifically, as shown in FIG. 8B , the power assembly 5 is used to drive the operating plate 13 of the syringe, so that the operating rod 12 performs linear movement in the barrel 11 of the syringe. The power assembly 5 includes a motor 51 , a lead screw 52 , a slider 53 and a connecting piece 54 assembled together. The lead screw 52 extends along the axial direction A as a whole, the lead screw 52 is connected to the output shaft of the motor 51 , and the lead screw 52 can be driven by the motor 51 . The slider 53 is sleeved on the lead screw 52 and can convert the rotation of the motor 51 into linear motion via the lead screw 52 . The slider 53 is connected to the operating panels 13 of the two

syringes

1a, 1b by means of the connecting piece 54. By controlling the motor 51 to rotate in different rotation directions, the operation panel 13 connected to the slider 53 can be controlled to move forward and backward, that is, the operation lever 12 connected to the operation panel 13 can be pulled in the barrel 11 of the syringe. and push.

如图8B所示，在第一实施例中喷头2的主体21的形成公共流路21c的部位，本实施例中的喷头2的主体21形成有安装凹部2c，该安装凹部2c可起到公共流路21c的作用，自适应幅宽调节组件6包括测距传感器61、推动杆62和导液片63。测距传感器61设置在喷头2的主体21的外壁上，用于感测待喷涂对象的目标喷涂区域距离喷头2的出口的直线距离。推动杆62设置在安装凹部2c中并且由动力单元提供动力。导液片63的中央部分与推动杆62相连，使得导液片63能够相对于推动杆62转动。主体21内的第一流路21a和第二流路21b的交汇部位在安装凹部2c的轴向一侧端部处形成有开口，两个导液片63的一端分别以能够转动的方式设置在该开口的两侧，导液片63的另一端处于自由状态，而且两个导液片63被构造成相对于安装凹部2c的中心线对称布置。这样，通过推动杆62能够控制导液片63彼此之间形成的喷角。实际上，在两个导液片63之间的空间实际用作之前实施例中的公共流路2c。As shown in FIG. 8B , in the portion of the main body 21 of the shower head 2 where the common flow path 21 c is formed in the first embodiment, the main body 21 of the shower head 2 in this embodiment is formed with a mounting recess 2 c , and the mounting recess 2 c can serve as a common The function of the flow path 21c, the adaptive width adjustment assembly 6 includes a distance measuring sensor 61 , a push rod 62 and a liquid guide plate 63 . The distance measuring sensor 61 is disposed on the outer wall of the main body 21 of the spray head 2 , and is used for sensing the linear distance between the target spraying area of the object to be sprayed and the outlet of the spray head 2 . The push rod 62 is provided in the mounting recess 2c and powered by the power unit. The central portion of the liquid guide piece 63 is connected to the push rod 62 , so that the liquid guide piece 63 can rotate relative to the push rod 62 . An opening is formed at an axial end of the mounting recess 2c at the intersection of the first flow path 21a and the second flow path 21b in the main body 21, and one end of the two liquid-conducting pieces 63 is rotatably provided thereon. On both sides of the opening, the other end of the liquid-conducting sheet 63 is in a free state, and the two liquid-conducting sheets 63 are configured to be symmetrically arranged with respect to the center line of the mounting recess 2c. In this way, by pushing the rod 62, the spray angle formed between the liquid guide sheets 63 can be controlled. Actually, the space between the two liquid conducting sheets 63 is actually used as the common flow path 2c in the previous embodiment.

以下参照图8C和图8D说明上述自适应幅宽调节组件6的工作原理和能够发挥的效果，根据公式tan(α/2)＝W/2h即可通过测距传感器61测量的高度值(图中的h1、h2)求算出特定幅宽(图中的W)下对应的喷头喷角(图中的α1和α2)。在实际应用中医护人员不可能手持设备一直稳定在一个固定的高度，再加上伤口高低不平等因素的影响都会直接影响喷涂的高度，继而直接影响喷涂的幅宽。如果要实现在不同的喷涂高度达到同样幅宽W进行喷涂，就需要能随时进行喷涂角的修正。测距传感器61实时测量喷头2出口位置与待喷涂对象的目标喷涂区域的直线距离，若因为手持设备向下抖动喷涂幅宽小于设定值，则可根据测距传感器61测量的数据，向压电推动杆62发送控制信号后进行收缩动作，从而将导液片63形成的喷头喷角张开从而增大喷涂幅宽，反之则收窄导液片63形成的喷头喷角从而缩小喷涂幅宽，完成稳定幅宽的喷涂工作。8C and 8D, the working principle and the effect that the above-mentioned adaptive width adjustment component 6 can exert will be described below. According to the formula tan(α/2)=W/2h, the height value measured by the distance measuring sensor 61 (Fig. h1, h2 in the figure) to calculate the corresponding nozzle angle (α1 and α2 in the figure) under a specific width (W in the figure). In practical applications, it is impossible for medical staff to hold the device at a fixed height all the time. In addition, the influence of the inequality of wound height will directly affect the height of spraying, which in turn directly affects the width of spraying. If you want to achieve the same width W for spraying at different spraying heights, you need to be able to correct the spraying angle at any time. The distance measuring sensor 61 measures the straight-line distance between the exit position of the nozzle 2 and the target spraying area of the object to be sprayed in real time. If the spray width is smaller than the set value because the hand-held device shakes downwards, then according to the data measured by the distance measuring sensor 61, the pressure After the electric push rod 62 sends a control signal, it performs a shrinking action, thereby expanding the spray angle of the nozzle formed by the liquid guide plate 63 to increase the spray width; otherwise, it narrows the spray angle formed by the liquid guide plate 63 to reduce the spray width , to complete the spraying work with stable width.

在本实施例中，送气单元可以包括电源、气泵和气体管路，气泵通过气体管路与进气管22连接。电源驱动气泵产生高压气体，高压气体经气体管路的输送至进气管22，最后进入喷头2内部流道对其中的医用胶进行吹散雾化。另外，为了便于操作，在本实施例中，医用胶喷涂装置的外壳形成为易于握持和操作的形状(如图8A所示)。In this embodiment, the air supply unit may include a power supply, an air pump and a gas pipeline, and the air pump is connected to the air intake pipe 22 through the gas pipeline. The power supply drives the air pump to generate high-pressure gas, and the high-pressure gas is transported to the air inlet pipe 22 through the gas pipeline, and finally enters the internal flow channel of the nozzle 2 to blow and atomize the medical glue therein. In addition, in order to facilitate the operation, in this embodiment, the housing of the medical glue spraying device is formed in a shape that is easy to hold and operate (as shown in FIG. 8A ).
