Background
In the medical operation of the present day, a plurality of medical instruments are used, which frequently contact with the skin, mucus or tissue fluid of a patient during the operation (especially the surgical operation), and in order to prevent the mucus or tissue fluid from adhering to the instrument and being contaminated, and further cross-infection of virus to other patients, all the medical instruments need to be sterilized after the use, or a disposable operation end portion is directly installed on the instrument, and since only the operation end portion contacts with the patient during the operation, the used operation end portion can be directly discarded and replaced with a new operation end portion after the operation.
However, whether a means of sterilizing or disposable tips is employed, it has its drawbacks in practice.
The problem with the disinfection flow is that: first, the disinfection machine needs to be purchased separately, thus increasing its monetary cost; second, the time consumed by the sterilization process and the labor involved in monitoring both affect the efficiency of the overall medical procedure.
the disposable process is problematic in that the disposable tips are frequently used, which is a large burden on the medical cost of the hospital, and the disposable tips may have an influence on the environment due to their special structure and characteristics of being not easily decomposed during the disposal and recycling processes.
In view of the above-mentioned drawbacks, manufacturers have designed special protective sleeves for some medical devices (such as endoscope, ultrasonic detector, laryngoscope, laryngeal mask, gastroscope, enteroscope, etc.), so that when the medical devices are covered with the protective sleeves during operation, the medical devices can be prevented from being infected with bacteria in a patient or other places, and after the operation is completed, the medical devices can be reused by only discarding the protective sleeves and installing new ones.
However, such a protective cover for medical use has the following problems in terms of production and use.
Firstly, the protective sleeves among the medical devices cannot be commonly used due to different shapes of the medical devices, so that the manufacturing is inefficient; secondly, the medical equipment can achieve better use efficiency only by tightly attaching the protective sleeve, so that the shape of the protective sleeve is more conformable to the appearance of the medical equipment in design and the protective sleeve is not easy to stretch, in other words, when a user sleeves the protective sleeve, the user is inconvenient, and even easily, the protective sleeve is too tight to continuously rub the surface of the medical equipment in the sleeving process, so that a hole is formed in the protective sleeve; third, if the difficulty of sleeving the protective sleeve is reduced, in other words, if the protective sleeve is easy to install, the protective sleeve is not attached to the medical device, and the efficiency of using the protective sleeve is reduced.
In summary, the prior art protective sheaths for medical devices have drawbacks in both manufacture and use.

In addition, the outer shell 10 can be formed by using the existing sputum suction tube in the hospital.
Referring to fig. 1, 2 and 6, the outer casing 10 has a gas opening 11, a placing opening 12 and at least one gas channel 13, in this embodiment, the gas opening 11 and the placing opening 12 are respectively located at two opposite ends of the outer casing 10, but the position of the gas opening 11 is not limited thereto, and the gas opening may also be located at other positions on the outer casing 10 according to the user's requirements.
in this embodiment, the number of the at least one gas channel 13 is plural, but not limited thereto, and there may be only one gas channel 13; the gas flow channels 13 are recessed around the inner wall surface of the outer casing 10, and each gas flow channel 13 extends to the placing opening 12 and the pressure adjusting space 101 of the outer casing 10, and more precisely, each gas flow channel 13 extends to two opposite ends of the outer casing 10 in the preferred embodiment.
Referring to fig. 1 and 2, the gas sealing member 20 is disposed on the outer casing 10 and seals the gas opening 11 of the outer casing 10, in this embodiment, the gas sealing member 20 includes a connecting member 21 and a one-way valve 22, the connecting member 21 penetrates through the gas opening 11, and the one-way valve 22 is disposed on the connecting member 21 and seals the gas opening 11; however, the gas seal 20 may have only one-way valve 22 without connecting member 21, which in these embodiments directly closes the gas opening of the outer housing.
In this embodiment, the gas flow direction of the check valve 22 is from the internal space 100 of the outer case 10 to the outside through the gas opening 11.
further, in other embodiments, the gas sealing member 20 may be a plug instead of a one-way valve, as long as it can close the gas opening 11 of the outer housing 10.
The placing sealing member 30 is disposed on the outer casing 10 and seals the placing opening 12 of the outer casing 10, in this embodiment, the placing sealing member 30 is inserted into the placing opening 12 and seals the placing opening, but the placing sealing member 30 may also be sleeved outside the outer casing 10 to seal the placing opening 12.
Referring to fig. 2 and 5, an instrument through hole 31 and a medical instrument fixing portion are further formed on the placing sealing member 30, in this embodiment, the instrument through hole 31 penetrates through the center of the placing sealing member 30, but the position of the instrument through hole 31 penetrating through the placing sealing member 30 is not limited by the center; the medical device fixing portion is formed on the inner wall surface of the device through hole 31 to connect the medical device 91, and in the present embodiment, the medical device fixing portion is integrally formed on the inner wall surface of the device through hole 31 and is forcibly interposed outside the medical device 91 by a frictional force to connect the placing seal 30 and the medical device 91 to each other to some extent, but the structure of the medical device fixing portion and the manner of connecting the medical device 91 are not limited thereto.
The protective sheath 40 is an elastic sheath, and more precisely, in the embodiment, the material of the protective sheath 40 is thermoplastic Rubber (TPR), but the material is not limited thereto; the protective sheath 40 is disposed in the outer casing 10 and expanded to abut against the inner wall surface of the outer casing 10, more precisely, opposite ends of the protective sheath 40 are respectively a sheath opening 41 and a closed end 42, the protective sheath 40 is connected to the instrument through hole 31 through the sheath opening 41, more precisely, in the embodiment, the sheath opening 41 is disposed outside the instrument through hole 31, in other words, the inner space 400 of the sheath 40 is connected to the outside through the sheath opening 41 and the instrument through hole 31, but the connection relationship between the sheath opening 41 and the instrument penetration hole 31 is not limited to a sleeve, other connection relationships are possible, such as the protective sleeve opening 41 is disposed through the instrument through hole 31 and surrounds the inner wall surface of the instrument through hole 31, so long as the protective sleeve 40 and the sealing member 30 together block the external air from entering the outer casing 10.
On the other hand, since the sheath opening 41 covers the instrument through hole 31 and the other end of the sheath 40 is the closed end 42, the inner space 400 of the sheath 40 is communicated with the instrument through hole 31 for placing the sealing member 30 and the outside through the sheath opening 41.
Referring to fig. 1, 2 and 3, further, since the protection sleeve 40 is disposed in the outer casing 10 in an expanded manner, in other words, the protection sleeve 40 is abutted against the inner wall surface of the outer casing 10 after being expanded, the closed end 42 of the protection sleeve 40, the gas sealing member 20 and the inner space of the outer casing 10 between the closed end 42 and the gas sealing member 20 together form a pressure regulating space 101, and the gas opening 11 of the outer casing 10 is located corresponding to the pressure regulating space 101, more precisely, when the gas opening 11 is not closed, it can communicate the outside with the pressure regulating space 101.
In this embodiment, the expansion of the protection sleeve 40 is caused by the fact that the internal space of the protection sleeve 40 is not communicated with the pressure adjustment space 101, and the pressure of the internal space of the protection sleeve 40 is greater than the pressure of the pressure adjustment space 101, so that the protection sleeve 40 can expand in the outer shell 10 due to the pressure difference; and, more specifically, the inside of the outer casing 10 is evacuated from the gas opening 11 of the outer casing 10, so that the protective sleeve 40 is gradually expanded inside the outer casing 10, thereby forming a kind of vacuum pressure-regulating space 101.
In addition, in the embodiment, the expansion degree of the protective sheath 40 in the outer shell 10 is one fifth of the maximum expansion amount that the material can bear, and the expansion degree can prevent the protective sheath 40 from elastic fatigue even if the protective sheath is expanded for a long time and is not used, but the expansion degree of the protective sheath 40 is not limited by this, and can be adjusted according to the requirement; when the protective sheath 40 is fully expanded with respect to the outer casing 10, the pressure adjustment space 101 is defined as a space surrounding the protective sheath 40, the inner wall surface of the outer casing 10, and the gas seal 20.
Referring to fig. 5, in the present embodiment, the thickness of the expanded protective sheath 40 at the closed end 42 is thinner than that at the opening 41 of the protective sheath, so as to avoid affecting the use of the internal medical device 91 (such as an endoscope, etc.), but the thickness is not limited thereto.
Referring to fig. 1 and 2, the pulling assembly includes a pulling rope 51 and a rope winding device 52, one end of the pulling rope 51 is connected to the closed end 42 of the protective sheath 40, and the other end of the pulling rope 51 extends out of the outer shell 10; the rope winding device 52 is relatively rotatably disposed on the outer housing 10, and in this embodiment, the other end of the pulling rope 51 passes through the check valve 22 and then is connected to the rope winding device 52, and the rotation of the rope winding device 52 can pull the pulling rope 51 to move.
In addition, in the embodiment, the rope winding device 52 is disposed on the connecting member 21 and the outer casing 10 through a connecting member 53 and a bolt 54, so as to be capable of rotating relative to the outer casing 10, but it is also possible to rotate the rope winding device 52 relative to the outer casing 10 by other means.
In other embodiments, the pulling device may have only one pulling rope without a rope winding device, and in this embodiment, one end of the pulling rope may be selectively pulled after extending outside the housing; in addition, the hauling cable body can also pass through the outer shell body through a structure other than the one-way valve.
Referring to fig. 8 to 10, in another embodiment of the present invention, at least one working tube 60 is further disposed in the protective sheath 40, the number of the at least one working tube 60 is preferably two, the two working tubes 60 are disposed in the protective sheath 40, two opposite ends of each working tube 60 are respectively formed with a tube opening 61, one end of each working tube 60 extends to the closed end 42 of the protective sheath 40 and is communicated with the pressure regulating space 101, and the other end thereof protrudes out of the instrument through hole 31 and is sealed by a working tube sealing element 62, and the working tube sealing element 62 may be a common plug.
In this embodiment, in each working pipe 60, the end of the working pipe extending to the closed end 42 of the protection sleeve 40 protrudes out of the closed end 42 of the protection sleeve 40 and extends into the pressure regulating space 101 to communicate with the pressure regulating space 101, but not limited thereto, the end may be flush-disposed on the closed end 42 of the protection sleeve 40 and does not protrude out of the closed end 42; in addition, in this embodiment, the working tube 60 extends through the end of the closed end 42 and is surrounded by a sealant with the closed end 42 to prevent gas from leaking into the protective sheath 40 through the end non-tube opening 61.
In this embodiment, the material of each working tube 60 is Ethylene Vinyl Acetate (EVA), but the material is not limited thereto.
The two working tubes 60 can be used for a user to further install auxiliary medical devices into the protective sheath 40, and when the user wants to use the working tubes 60, the user only needs to remove the working tube sealing member 62 and then place the medical device to be placed into the working tube 60.
the following is a method for installing a vacuum protection sleeve installation component of a medical apparatus, comprising the following steps:
Preparation step (S1): referring to fig. 1 to 4, an outer casing 10, a protective cover 40, a traction rope 51, an air-extracting device 71 and a sleeving guide 72 are prepared; one end of the outer shell 10 is a placing opening 12; the protective sleeve 40 is an elastic sleeve body, the protective sleeve 40 is arranged in the outer shell 10, two opposite ends of the protective sleeve 40 are respectively provided with a protective sleeve opening 41 and a closed end 42, and the inner space of the protective sleeve 40 is communicated with the placing opening 12 of the outer shell 10; in this embodiment, the outer shell 10, the protection sleeve 40 and the pulling rope 51 are the same as the above-mentioned structures, and therefore the structural features thereof will not be described herein again, but the structures of the outer shell 10 and the protection sleeve 40 of the installation method of the present invention are not necessarily the same as those of the outer shell 10 and the protection sleeve 40 of the vacuum protection sleeve installation assembly.
Referring to fig. 2 and 4, the process of disposing the protective sheath 40 on the outer casing 10 is to first pass the sleeving guide 72 through the instrument through hole 31 to place the sealing member 30, and then the protective sheath 40 is sleeved on the sleeving guide 72 and moves toward the sealing member 30 along the outer wall surface of the sleeving guide 72; because the sleeve guide 72 has a conical structure, the opening 41 of the protective sleeve 40 is gradually enlarged during the movement toward the sealing member 30; after the protection sleeve 40 is moved to the position where the sealing member 30 is placed and sleeved outside the placing sealing member 30, the protection sleeve 40 and the placing sealing member 30 are installed in the placing opening 12 of the outer shell 10, and the step of installing the protection sleeve 40 in the outer shell 10 is completed; the sheathing guide 72 is removed after the protection sheath 40 is sheathed on the placing and sealing member 30, and more precisely, the user can remove the sheathing guide 72 in advance and then place the sealing member 30 on the outer housing 10, or remove the sheathing guide 72 and the placing and sealing member 30 together on the outer housing 10.
as shown in fig. 3, the air extractor 71 is extended from the air opening 11 of the outer housing 10 into the outer housing 10, and air is extracted between the air opening 11 and the closed end of the protective sleeve 40, when the air pressure therein is gradually reduced, since the protective sleeve 40 maintains an atmospheric pressure communicated with the outside through the protective sleeve opening 41, the pressure of the protective sleeve 40 is gradually greater than the pressure at the air extraction position, the protective sleeve 40 is gradually expanded in the outer housing 10 by the pressure difference, when the protective sleeve 40 is expanded until the protective sleeve 40 is completely attached to the inner wall surface of the outer housing 10, the air extraction is completed, and the pressure adjusting space 101 is formed between the air opening 11, the inner wall surface of the outer housing 10, and the closed end 42 of the protective sleeve 40.
As shown in fig. 6, in the air-extracting process, in order to avoid the uneven expansion of the protection sleeve 40, which causes the portion near the air opening 11 to expand in advance to block the gap capable of being extracted from the outer shell 10, the air flow channel 13 can allow air to flow from any portion of the outer shell 10 to the air-extracting device 71, so as to achieve the purpose of uniform and sufficient expansion of the protection sleeve 40.
Referring to fig. 8 and 9, in the preparation step, the user may further install at least one working tube 60 in the protective sheath 40, and when the at least one working tube 60 is installed on the protective sheath 40 and the air extractor 71 extracts air from the inside of the outer casing 10, the end of each working tube 60 communicating with the outside needs to be sealed by the working tube sealing element 62, so as to prevent the inside of the outer casing 10 from continuously communicating with the outside through the working tube 60, and the inside cannot achieve the effect of sealing.
Referring to fig. 1 and 3, in terms of installation of the pulling rope 51, one end of the pulling rope 51 is accommodated in the pressure regulating space 101 and connected to the closed end 42 of the protective sheath 40, and the other end of the pulling rope 51 extends to a rope winding device outside the outer shell 10.
furthermore, during this evacuation process, to ensure that the protective sheath 40 effectively extends toward the gas opening 11, the user pulls the pulling rope 51, so that the protective sheath 40 can be pulled by the pulling rope 51 to move and expand toward the gas opening 11 while expanding.
After the protective cover 40 is installed and expanded, the protective cover 40 is expanded on the inner wall surface of the outer casing 10 by the pressure difference, and a pressure adjusting space 101 is formed between the closed end 42 of the protective cover 40 and the inner wall surface of the outer casing 10, the inner space of the protective cover 40 is not communicated with the pressure adjusting space 101, and the pressure in the protective cover 40 is greater than the pressure of the pressure adjusting space 101, so that the preparation step of the method is completed (S1).
Instrument insertion step (S2): referring to fig. 1, 5 and 6, a medical device 91 is placed into the protective sheath 40 from the placement opening 12, and the outer casing 10 in this embodiment is a circular tube-shaped elongated casing, so that the medical device is particularly suitable for elongated medical devices, such as an endoscope, an ultrasonic probe, a laryngoscope, a laryngeal mask, a gastroscope, an enteroscope, and the like.
Referring to fig. 5 and 6, in addition, after the medical device 91 extends into the protective sheath 40, since the medical device is inserted into the protective sheath 40 through the device through hole 31, the medical device fixing portion on the device through hole 31 is tightly pressed against the periphery of the medical device 91, so as to achieve the effect of stabilizing the medical device 91 by friction and avoid the possibility of shaking during the enveloping process.
Coating step (S3): referring to fig. 3, 6 and 7, the sealing state of the check valve 22 is released to allow the pressure-adjusting space 101 to communicate with the outside, so that the protective sheath 40 gradually contracts as the pressure of the pressure-adjusting space 101 gradually increases to conform to the outside, and finally covers and adheres to the surface of the medical device 91.
In the coating step, if the gas sealing member 20 is a simple plug, the user only needs to pull out the plug to release the sealing state of the pressure regulating space 101, and the pressure regulating space 101 is communicated with the outside; however, the term "communicate with the outside" may be used to refer to any means for pressurizing the pressure-adjusting space 101, such as directly increasing the pressure of the pressure-adjusting space 101 by a pressurizing device, etc., in other embodiments.
referring to fig. 1 and 2, in order to prevent the medical device 91 and the protective sheath 40 from being ejected from the device through hole 31 due to too fast and strong contraction of the protective sheath 40, the user can rotate the rope winding device 52 in a direction away from the placement opening 12 (and the device through hole 31) by the pulling rope 51, so that the pulling rope 51 resists the contraction force of the protective sheath 40, and the contraction rate of the protective sheath 40 is reduced.
In addition, in the embodiment, the radial length of the protection sheath 40 when it is not expanded is smaller than the radial length of the medical device 91 to be sheathed, so that the protection sheath 40 can be tightly attached to the surfaces of the medical device 91 to be enveloped when it is gradually shrunk from the expanded state and covers the medical device 91.
Instrument removal step (S4): after the protective sheath 40 is firmly covered on the medical device 91 to be encapsulated, the medical device 91 and the protective sheath 40 are taken out together from the device through hole 31, thereby completing encapsulation of the medical device 91.
Further, in the preparation step, a flow of evacuation (vacuuming) may not be included; more precisely, the present invention may be designed such that a person skilled in the art can previously perform the steps of evacuating the interior of the outer case 10 and expanding the protective cover 40 with respect to the outer case 10 to produce a plurality of inflated protective covers 40, whereby the user can simply perform the steps of placing the medical device 91 into the outer case 10(S2), pressurizing the pressure-adjusting space 101 to contract the protective cover 40 (S3), and taking out the medical device 91 covered with the protective cover 40 (S4) in order to attach the protective cover 40 to the medical device 91.
The advantages of the invention are as follows:
firstly, since the user can sleeve the protective sheath 40 on the medical instrument 91 by only putting the medical instrument 91 into the protective sheath 40 through the instrument through hole 31 and releasing the airtight state of the pressure adjusting space 101, the protective sheath 40 can be quickly and accurately sleeved on the medical instrument 91, thereby achieving an efficient protective sheath installation process;
Secondly, because the protective sleeve 40 is installed by expanding and then contracting, and the protective sleeve 40 is made of stretchable material, the protective sleeve can be used for medical instruments 91 with different shapes, and the manufacturing cost is saved;
Thirdly, because the protective sleeve 40 expands and contracts by pressure difference in the installation process to achieve the purpose of covering the medical apparatus 91, the protective sleeve 40 does not generate excessive friction with the surface of the medical apparatus 91 in the installation process, and therefore the protective sleeve 40 is less prone to rupture due to friction with the medical apparatus 91 in the installation process;
Fourth, even if the protection cover 40 is broken during installation, the protection cover 40 is expanded by pressure difference, and the broken protection cover 40 cannot maintain the sealing effect between the inside of the protection cover 40 and the pressure adjustment space 101, so that the broken protection cover 40 cannot be expanded during installation, and the user can know that the protection cover 40 is broken, thereby achieving the effect of rapidly and accurately identifying the broken protection cover 40.
Fifth, the working tube 60 is provided to provide further convenience for the user, and more precisely, when the user wants to further use the auxiliary medical device as an auxiliary device of the main medical device covered with the protective sheath 40, the user can detach the sealing member 62 of the working tube 60 and put the auxiliary medical device into the working tube 60 through the tube opening 61 thereof, so that the auxiliary medical device can be extended into the protective sheath 40 to be used together with the main medical device; in other words, through the working tube 60, the user can match the main medical device with different auxiliary medical devices according to his needs.
Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited to the above embodiments, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention.
