Background

The infusion is a method of injecting liquid medicine into human body's vein by using the principle of pressure difference (gravity) produced by liquid drop height, and is a common method for clinical rescue and treatment of patients.

The work of intravenous drip infusion has been manually operated, monitored and cared by medical personnel for many years. Due to uncertainty of environment factors of manual operation behaviors, such as: dust, fiber bacteria, viruses or other particles in the air, and uncertain environmental influence factors of medical personnel can cause imperceptible pollution to liquid medicine when the medical personnel carry out transfusion and convert the transfusion bottle, thereby bringing negative effects to clinical safe medication.

In addition, the conventional artificial intravenous drip infusion often has the phenomenon of over-input of liquid medicine due to untimely manual monitoring, so that negative pressure difference is generated between the inside of the infusion tube and blood, the blood flows back into the infusion tube, and serious consequences are caused. The biggest harm is that in order to reduce workload, medical staff can re-input the blood in a coagulated state in the infusion tube into the blood of a patient, which may bury the pen-hold for the formation of thrombus and may increase the incidence of cerebral thrombosis and cerebral infarction.

When the artificial intravenous drip is used for transfusion, the needle inserted by medical staff cannot be completely inserted into a vein, so that the liquid medicine is injected into the muscle of a patient, the medical staff cannot find the needle in time, and the phenomenon of edema of the peripheral skin and the muscle of the needle inserted by a transfusion person when the needle is found not can be caused, so that the liquid medicine loss can be caused, the treatment effect can be influenced, and the pain of frosting on snow can be caused for the patient.

In the infusion process, no equipment for well controlling the infusion temperature exists in the existing market, and only one simple heating rod is used for heating the temperature of the infusion liquid in the existing market; and the heater is disposable, so that the heater can not be repeatedly used and is much wasted.

An effective solution to the problems in the related art has not been proposed yet.

Fig. 5 is a schematic structural view showing an embodiment of the fixing device for changing a bottle of an infusion bottle of the present invention. Referring to fig. 6 and 7, the device for automatically fixing an infusion bottle of the present invention comprises: a holding mechanism 101 for holding and fixing an infusion bottle, a driving mechanism 102 provided at the lower end of the holding mechanism 101 for driving the holding mechanism 101 to fix and release the infusion bottle, and a stopper mechanism 103 capable of changing the movement locus of the holding mechanism 101 by stopping the holding mechanism 101 and the driving mechanism 102. Also, in order to achieve the function of fixing or releasing the iv bag by the holding mechanism 101, the holding mechanism 101 includes a first engaging member 101a and a second engaging member 101b provided to engage with the first engaging member 101 a. Preferably, the "cooperative arrangement" described herein is embodied in two aspects: first, the first engaging member 101a and the second engaging member 101b are arranged to be opposed to each other in a "mirror image"; secondly, the first engaging member 101a and the second engaging member 101b can move synchronously relative to each other or in opposite directions, and an engaging space for fixing or releasing the infusion bottle is formed. In this embodiment, the first engaging member 101a and the second engaging member 101b are both provided with notches, and the notch structure is formed so that the holding mechanism 101 can better engage with the infusion bottle. The first engaging member 101a is further provided with a first boss, and the term "first boss" as used herein means: (see fig. 7) extends downward from one end of the first engaging member 101a where the plane where the recess is formed, then expands to one side to form a first interference surface 101a-2, then slopes downward to form a fifth interference surface 101a-4, and finally extends downward to interfere with the first guide surface 101 a-1. In this embodiment, the "back" opposite the first interference surface 101a-2 is the third interference surface 101 a-3. Correspondingly, the second engaging member 101b is provided with a second boss, where the "second boss" refers to: the second engaging member 101b extends downward from the end of the plane where the recess is formed, then extends to the side opposite to the first boss to form a second interference surface 101b-2, then slopes downward to form a sixth interference surface 101b-4, and finally extends downward to interfere with the second guide surface 101 b-1. In this embodiment, the "back" opposite the second interference surface 101b-2 is the fourth interference surface 101 b-3.

Fig. 7 is a partially disassembled schematic view of the infusion bottle fixing device according to the embodiment of the present invention, and referring to fig. 6, the limiting mechanism 103 forms a hollow first rail space S1 and a hollow second rail space S2 by wrapping surfaces (i.e., a side surface, an upper end surface and a lower end surface). The first rail space S1 encloses the first boss, the first transmission member 102b, and the first transmission stopper member 102d therein, and the second rail space S2 encloses the second boss, the second transmission member 102c, and the second transmission stopper member 102e therein. The notch structures of the first engaging member 101a and the second engaging member 101b are disposed on the front surface of the wrapping surface. In this embodiment, the first wrapping surface 103a refers to a side surface of the wrapping surface which is vertically arranged and is close to the second wrapping surface 103 b. Thus, the back of the upper end surface of the wrapping surface in the horizontal direction forms a first stopper surface a, and the top end surfaces of the first wrapping surface 103a and the second wrapping surface 103B form a second stopper surface B. Meanwhile, inclined surfaces, i.e., a third limit surface P and a fourth limit surface Q, are provided on both sides of the upper end of the limit mechanism 103. The structure of the limiting mechanism 103 is configured such that the first limiting surface a can limit the first collision surface 101a-2 and the second collision surface 101B-2 when the first limiting surface a ascends, in one embodiment, the second limiting surface B can be configured to limit the third collision surface 101a-3 and the fourth collision surface 101B-3 when the second limiting surface B horizontally moves, preferably, in order to better complete the movement of the first engaging member 101a and the second engaging member 101B, in another embodiment, the second limiting surface B is configured not to perform any support or limit on the third collision surface 101a-3 and the fourth collision surface 101B-3. The lower end face of the horizontal direction of the wrapping surface can limit the first transmission component 102b, the first transmission braking component 102d, the second transmission component 102c and the second transmission braking component 102e when falling, and the third limiting face P and the fourth limiting face Q can limit the fifth collision face 101a-4 and the sixth collision face 101b-4 respectively, so that when the first clamping component 101a and the second clamping component 101b move to the limiting positions of the third limiting face P and the fourth limiting face Q, the first clamping component 101a and the second clamping component 101b are guaranteed to generate opposite movement force, the force of butt sliding can be guaranteed, and the conversion from horizontal movement to vertical movement can be conveniently realized. As shown in fig. 4, a height difference exists between the second limiting surface B and the first limiting surface a, and provides a moving space for the horizontal portions of the first boss and the second boss.

The power unit 102a supplies driving force to the driving mechanism 102 for fixing and releasing the iv bag. The driving mechanism 102 includes a power member 102a, and a first transmission member 102b and a second transmission member 102c connected to the power member 102a, and further includes a first transmission brake member 102d and a second transmission brake member 102 e. In this embodiment, the power unit 102a includes a power source 102a-1, a transmission push plate 102a-2 disposed at an upper end of the power source 102a-1, and a transmission push rod 102a-3 disposed at both ends of the transmission push plate 102a-2 and connected to the first transmission unit 102b and the second transmission unit 102c, respectively. The power source 102a-1 may be selected here as a hydraulic rod, but is not particularly limited as long as it is formed as a mechanism capable of reciprocating in the vertical direction. In order to accurately position the positional relationship of the first transmission brake member 102d and the second transmission brake member 102e, the symmetry axes of the first transmission member 102b and the second transmission member 102c are assumed with reference to the first transmission member 102b and the second transmission member 102c which are symmetrically arranged with respect to each other. The first transmission braking part 102d is disposed at a side of the first transmission part 102b and near the symmetry axis, and the second transmission braking part 102e is disposed at a side of the second transmission part 102c and near the symmetry axis.

The first transmission brake component 102d and the second transmission brake component 102e can be selected as brake pads, i.e., rectangular parallelepiped structures. The first transmission brake part 102d and the second transmission brake part 102e are higher than the lowest position of the first transmission part 102b and the second transmission part 102c, respectively, in the vertical height. As shown in fig. 7, the first transmission member 102b is provided with a first transmission surface 102b-1 which is matched with the first guide surface 101a-1, wherein the matching means that the two surfaces (i.e. the first guide surface 101a-1 and the first transmission surface 102b-1) can move relatively under the action of the transmission force in the structural arrangement. In this embodiment, first drive face 102b-1 is disposed in a configuration that is inclined to below the "axis of symmetry". Correspondingly, the second transmission part 102c is provided with a second transmission surface 102c-1 matched with the second guide surface 101b-1, and the second transmission surface 102c-1 is also arranged to be inclined towards the lower part of the symmetrical axis. Taking the example that the first guiding surface 101a-1 is relatively displaced on the first driving surface 102b-1, the first guiding surface 101a-1 is away from the farthest end of the first driving surface 102b-1 with the inclined structure to the outer side wall of the first driving brake component 102d, so that there is a moving distance that can bring the first boss close to the first driving brake component 102d and far away from the first driving brake component 102 d. Preferably, the movable distance is equal to twice the distance where the recesses on the first and second snap parts 101a, 101b are closest to each other. Here, the "farthest end of the first transmission surface 102 b-1" means the highest point of the first transmission surface 102b-1, which is arranged obliquely, from the horizontal plane where the transmission push plate 102a-2 is located; the "outer side wall" of the first transmission/braking part 102d "is defined as" outer "and" inner "with respect to the" symmetry axis ", i.e., the end close to the" symmetry axis "is defined as" inner "and the end far from the" symmetry axis "is defined as" outer ". Similarly, the second guiding surface 101b-1 is capable of providing a moving distance for the second boss to approach the second driving-stopping part 102e and move away from the second driving-stopping part 102e from the farthest end of the second driving surface 102c-1 of the inclined structure to the outer side wall of the second driving-stopping part 102 e. Preferably, the movable distance is also equal to twice the distance where the recesses on the first and second snap parts 101a, 101b are closest to each other. Here, the "farthest end of the second transmission surface 102 c-1" means the highest point of the second transmission surface 102c-1, which is obliquely arranged, away from the horizontal plane where the transmission push plate 102a-2 is located; in contrast, the "outer side wall" of the second transmission brake component 102e "is" outer "or" inner "relative to the" symmetry axis ", i.e. the end close to the" symmetry axis "is" inner "and the end far from the" symmetry axis "is" outer ".

Thus, when the first projection abuts against the outer side wall of the first transmission braking part 102d, the notches of the first clamping part 101a and the second clamping part 101b are just clamped, so as to "lock" the bottleneck position of the infusion bottle. The special setting of the 'moving distance' can ensure that the bottleneck of the infusion bottle is clamped at the right center position, and the infusion bottle is firmer and more stable. In this embodiment, the first transmission surface 102b-1 is provided with protrusions of "inwardly inclined" side surfaces, which can be engaged with the grooves of "inwardly inclined" side surfaces of the first guide surface 101 a-1; while the second drive surface 102c-1 and the second guide surface 101b-1 are also symmetrically designed as the first drive surface 102b-1 and the first guide surface 101a-1, respectively. The term "inwardly sloping" side as used herein refers to an inverted trapezoid when viewed from a side view.

As shown in fig. 8 to 10 and fig. 7, fig. 8 to 10 can be regarded as schematic views of the entire operation process of the holding mechanism 101 and the driving mechanism 102. In the utility model discloses, when power part 102a provides power transmission for first transmission part 102b, first transmission brake part 102d and second transmission part 102c, second transmission brake part 102e, first transmission part 102b and first transmission brake part 102d "promote" first boss and move up along the vertical direction inside first track space S1, and in step, second transmission part 102c and second transmission brake part 102e "promote" second boss and move up along the vertical direction inside second track space S2, upward move to first conflict face 101a-2 and second conflict face 101b-2 conflict to first spacing face A respectively. Due to the limitation of the position of the first limiting surface A, the first boss and the second boss cannot move upwards continuously, the power component 102a continuously provides power in the vertical direction, the inclined third limiting surface P and the inclined fourth limiting surface Q start to generate limiting force action on the fifth interference surface 101a-4 and the sixth interference surface 101b-4, the first guide surface 101a-1 of the first boss is forced to move downwards along the first transmission surface 102b-1, and the whole first boss is changed from the movement in the vertical direction to the movement in the horizontal direction; similarly, the second guide surface 101b-1 of the second boss moves downwards along the second transmission surface 102c-1, the movement of the second boss in the whole vertical direction is changed into the movement in the horizontal direction, and finally the notch 'polymerization' of the first clamping part 101a and the notch 'polymerization' of the second clamping part 101b is realized, and the clamping of the infusion bottle is completed.

The "release" of the iv bottle can be easily understood in accordance with fig. 10, 9, and 8. At this time, the power component 102a provides vertical downward power transmission to the first transmission component 102b, the first transmission braking component 102d, the second transmission component 102c and the second transmission braking component 102e, and the first guide surface 101a-1 and the first transmission surface 102b-1 move in a matching way through the mutually-embedded inverted trapezoid clamping grooves; the second guide surface 101b-1 and the second transmission surface 102c-1 are also moved in a matching manner through the mutually-embedded inverted trapezoid-shaped clamping grooves, and vertical force is provided at the moment, so that the matching movement between the clamping grooves has a 'compulsive' characteristic, namely, the first boss and the second boss are similar to a 'tearing' movement and a 'separation' movement towards two sides along the first transmission surface 102b-1 and the second transmission surface 102c-1 respectively. The separation motion in the horizontal direction is carried out until the first boss and the second boss are abutted to the inner wall of the side face of the wrapping face, the first boss and the second boss cannot move horizontally continuously due to the limitation of the position of the inner wall of the side face of the wrapping face, the power component 102a continuously provides power in the vertical direction, the first boss is forced to move vertically downwards in the first track space S1, and the motion in the horizontal direction of the whole first boss is changed into the motion in the vertical direction; similarly, the second boss moves vertically downward in the second rail space S2, and the movement of the second boss in the horizontal direction is changed into the movement of the second boss in the vertical direction as a whole. The downward movement is continued, and finally the notches of the first clamping part 101a and the second clamping part 101b are separated, so that the infusion bottle is released.

Preferably, as shown in fig. 11, in order to better realize the engagement or release of the first engaging member 101a and the second engaging member 101b with or from the infusion bottle, in this embodiment, a first elastic member 102f is disposed between the first transmission braking member 102d and the first engaging member 101a for realizing the return balance of the first engaging member 101 a; meanwhile, a second elastic member 102g is provided between the second transmission braking member 102e and the second engaging member 101b for achieving a return balance of the second engaging member 101 b. Fig. 12 is a schematic cross-sectional view of the holding mechanism 101 and the driving mechanism 102 according to this embodiment of the present invention, and it can be seen from the figure that the first elastic member 102f from the first transmission braking member 102d collides with the inside of the first boss along the first transmission surface 102b-1, where "from the first transmission braking member 102 d" may be selected to have a notch on the outer side surface of the first transmission braking member 102d to serve as the fixed end of the first elastic member 102 f; the term "abutting against the inside of the first boss" means that a space is formed from a side surface of the first boss to the inside so as to form a space for restoring the balance of the first elastic member 102 f. Similarly, the second elastic member 102g is inclined from the second driving brake member 102e and interferes with the inside of the second boss along the second driving surface 102 c-1. When the infusion bottle is released (namely, the horizontal movement is changed into the vertical movement), the first elastic part 102f and the second elastic part 102g provide restoring force for the first boss and the second boss, so that the first clamping part 101a and the second clamping part 101b can conveniently change the vertical movement into the horizontal movement, and meanwhile, the restoring balance of the first clamping part 101a and the second clamping part 101b is also facilitated.

Therefore, in an embodiment, as shown in fig. 1 and 2, the infusion bottle changing fixing device of the present invention can dispose all of the driving member 301 and the gradually changing member 302, except for the hanging member 302c, in the housing. Of course, a notch for installing other devices is reserved in the housing, and when the hanging member 302c rotates the infusion bottle to the position above the infusion bottle fixing device 100 in the infusion bottle fixing puncture device, the first engaging member 101a and the second engaging member 101b engage and fix the bottleneck of the infusion bottle. After the infusion is completed, the needle of the infusion tube is pulled out of the infusion bottle, the first engaging member 101a and the second engaging member 101b release the infusion bottle, and the hanging member 302c is rotated to replace the new infusion bottle. In one embodiment, the infusion bottle changing fixing device can further comprise a control part 303 connected with the driving part 301 and used for controlling the driving part 301 to operate and stop. In this embodiment, the photoelectric sensor 304 and the iv bottle neck position measuring device 305 are provided to control whether or not the iv bottle reaches the "upper side of the iv bottle fixing apparatus 100" and the height of the iv bottle falling, in order to control the engagement, piercing, and bottle changing operations in a more coordinated manner. The photoelectric sensor 304 and the infusion bottle neck position measuring device 305 are connected to the control unit 303, and the measurement parameters are fed back to the control unit 303, thereby controlling the operation of the infusion bottle changing and fixing puncture device.

Fig. 13 is a schematic configuration diagram showing an embodiment of the puncture device for fixing an infusion bottle according to the present invention. The utility model discloses a puncture device is fixed to infusion bottle has: an infusion bottle fixing device 100 capable of clamping and fixing an infusion bottle, and a puncture mechanism 200 capable of puncturing a cap of the infusion bottle. In this embodiment, the puncture mechanism 200 includes a puncture device fixing member 201 capable of moving relative to the stopper mechanism 103, and a transmission member 202 having one end connected to the puncture device fixing member 201 and the other end connected to the power source 102 a-1. In this embodiment, specifically, one end of the transmission component 202 passes through the transmission push plate 102a-2 to be movably connected with the transmission push plate 102a-2, and the other end thereof abuts against the transmission push block 102a-4 arranged at the upper end of the power source 102 a-1. The transmission push block 202b is provided with a first limit pull rod 202b-1 and a second limit pull rod 202b-1, the first limit pull rod 202b-1 and the second limit pull rod 202b-1 extend upwards from a plane of the transmission push block 202b and extend through the transmission push plate 102a-2, the first limit pull rod 202b-1 and the second limit pull rod 202b-1 are movably connected with the transmission push plate 102a-2, the top ends of the first limit pull rod 202b-1 and the second limit pull rod are respectively provided with a limit surface, a fourth elastic part 202a is arranged on a transmission part 202 located between the transmission push block 202b and the transmission push plate 102a-2, and the fourth elastic part 202a is fixedly connected with the transmission push block. The top ends of the first limit pull rod 202b-1 and the second limit pull rod 202b-1 are provided with limit surfaces, and in one embodiment, the structure may be: the transmission push plate 102a-2 is provided with a movable hole, the movable hole comprises a large-aperture part and a small-aperture part, and the limiting surfaces limiting the first limiting pull rod 202b-1 and the second limiting pull rod 202b-1 can penetrate through the large-aperture part and can not enter the small-aperture part. The transmission member 202, in one embodiment, may be a straight rod having one end directly connected to the power source 102a-1 of the power member 102a, the straight rod passing through the transmission push plate 102a-2, and the other end spaced apart from the sliding member 201a by a distance d 2. Preferably, the transmission component 202 is provided with a fourth elastic component 202a, and the fourth elastic component 202a is located at a position between the transmission push block 202b and the transmission push plate 102a-2, although a spring may be used as the "elastic component" described herein. Thus, referring to FIGS. 20-22, in the initial state, the fourth spring member 202a is compressed by the first and second position-limiting rods 202b-1 and 202b-1 to generate a tension force F1, and a maximum distance d1 is ensured by the first and second position-limiting rods 202b-1 and 202 b-1. When the power source 102a-1 provides power to push the transmission member 202, a pushing force of F2 is generated, at this time, the first engaging member 101a and the second engaging member 101b are not engaged yet, F1 is always greater than twice F2, and twice F2 is 2F 2. Therefore, the distance d1 can not be changed all the time, only when the first engaging member 101a and the second engaging member 101b are engaged, F2 becomes large, then the top end of the transmission member 202 reaches the bottom of the sliding member 201a to abut against the puncturing mechanism 200, at this time, 2F2 is larger than F1, all parts keep relative positions under the limit of the limiting mechanism 103, the transmission push plate 102a-2 starts to block the fourth elastic member 202a from advancing, the spring is pressed under the action of power to make d1 become small, the transmission member 202 pushes the sliding member 201a to advance, and the needle of the infusion tube fixed by the locking member 201b is driven to be inserted into the bottle cap.

Referring to fig. 7 and 15, the limiting mechanism 103 forms a first hollow track space S1 and a second hollow track space S2 by the wrapping surfaces (i.e., the side surfaces, the upper end surface and the lower end surface), and in this embodiment, the puncture device fixing part 201 can move relative to the limiting mechanism 103 as described herein, which can be realized by the following technical solutions: the first rail space S1 and the second rail space S2 are set to be spaced apart from each other to form a mounting space M, a puncture rail 103c is provided on one side (e.g., a front side in fig. 15) of the mounting space M, and a slider 201a (see fig. 16) which is engaged with the puncture rail 103c is provided on the puncture device fixing member 201, that is, the slider 201a may be provided in the puncture rail 103c and can slide vertically in the puncture rail 103 c. In one embodiment, the upper end of the sliding member 201a is provided with a third elastic member 201c, and the third elastic member 201c abuts against the upper closed end of the puncture track 103c to balance the sliding member 201 a. Of course, the puncture instrument fixing member 201 is further provided with a locking member 201b for fixing the infusion tube. The "locking member 201 b" described herein shall include two embodiments as follows: for the type i infusion tube shown in fig. 17, the locking part 201b is a buckle channel provided on the puncture device fixing part 201, the width of the buckle channel is matched with the width of a 'buckle section' (labeled as 'l' in fig. 13) of the type i infusion tube, and the type i infusion tube can be fixed by the buckle of the buckle channel; secondly, for the type ii infusion tube shown in fig. 18, the locking part 201b is a loading space with three hollowed-out surfaces, and the loading space can load and fix a drip cup (marked as "L" in fig. 18) of the type ii infusion tube.

Thus, when the power source 102a-1 provides power to push the transmission push plate 102a-2 to move, the transmission component 202 temporarily keeps the distance from the transmission push plate 102a-2 unchanged under the action of the elastic force of the fourth elastic component 202a and the limiting action of the first limiting pull rod 202b-1 and the second limiting pull rod 202b-1, the transmission push plate 102a-2 transmits the power to the transmission push rod 102a-3 to push the first transmission component 102b and the second transmission component 102c connected therewith, at this time, because the first transmission component 102b and the second transmission component 102c are respectively and correspondingly connected with the first clamping component 101a and the second clamping component 101b, the first clamping component 101a and the second clamping component 101b also start to move in the vertical direction, and when the first collision surface 101a-2 and the second collision surface 101b-2 collide with the first limiting surface a, the first clamping component 101a and the second clamping component 101b stop moving upwards, at the moment, the power source 102a-1 continues to provide power, the transmission push plate 102a-2 continues to transmit the movement in the upward direction, so that the first clamping component 101a and the second clamping component 101b start to move along the first transmission surface 102b-1 and the second transmission surface 102c-1 respectively, at this time, the vertical movement is changed into the horizontal movement, and the first elastic component 102f and the second elastic component 102g are compressed, when the clamping state of the infusion bottle is realized, the first elastic component 102f and the second elastic component 102g are compressed to the maximum deformation state, that is, at this time, the first elastic component 102f and the second elastic component 102g are compressed to have the maximum elastic potential energy. At this time, the transmission part 202 compresses the fourth elastic part 202a to move continuously under the action of power, so as to push the sliding part 201a continuously to drive the puncture outfit fixing part 201 which locks the transfusion tube by the locking part 201b to move upwards, thereby completing the puncture insertion of the bottleneck of the transfusion bottle. Of course, this process is performed while the compression of the third elastic member 201c is also completed. At this time, the magnitude of the restoring force generated by the elastic component is, from large to small: third elastic member 201c > fourth elastic member 202a > first elastic member 102f ═ second elastic member 102 g.
