Description

Technical Field

[0001] The utility model belongs to the technical field of medical and nursing supplies, and particularly relates to a protective sleeve for a pediatric trocar. Background Art

[0002] The trocar, also known as the cannula acupuncture needle, is a new type of therapeutic tool that places a traditional acupuncture needle into a piston-type cannula. The cannula is a special needle holder, equipped with a special acupuncture needle, which stimulates and relaxes the local muscles. Through the conduction of nerves, it regulates the body functions of internal organs or diseased areas to achieve the therapeutic purpose. The implantation steps of the trocar are as follows: first, insert the trocar into the subcutaneous tissue of the target point, then pull out the inner needle in the trocar, load the absorbable protein thread body into the outer needle of the trocar, and then insert the needle core into the outer needle to push the thread body, so that the thread body is pushed into the subcutaneous tissue at the target point. Clinically, the trocar is also applied to children. However, when children use the trocar, the following situations exist: due to the poor self-control ability of children and their fear during the application of the trocar, during the implantation and retention period of the trocar, children often pull and kick it, which may cause the trocar to shift or even fall off, resulting in the failure of the trocar and potentially causing secondary harm to children.

[0003] To alleviate the above problems, in the current operation method, some protective articles (usually socks are selected as the common protective articles) are usually used to cover the implanted trocar. This method has the following defects: firstly, the existing protective articles are not standardized items, which makes it difficult to standardize the operation methods of different medical staff; secondly, when the protective articles are applied to children, they cannot be too loose or too tight. Being too loose is easy to fall off, and being too tight is easy to cause pressure damage, and the existing protective articles are difficult to meet this requirement; furthermore, during the retention period of the trocar, medical staff also need to observe and operate it regularly. The existing protective articles usually hinder medical operations. At this time, the protective articles can only be removed as a whole, and then re-worn after the operation is completed, resulting in discomfort for children.

[0004] In summary, it is necessary to develop and design a protective sleeve device for pediatric trocars to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a protective sleeve for a pediatric trocar, which is used as a standardized consumable to improve the standardization level of medical staff's operations, has a suitable tightness to avoid problems of falling off and pressure damage, does not affect medical staff's observation and operation of the indwelling needle during wearing, and reduces the discomfort of children.

[0006] The technical solution adopted by the present utility model is as follows: A protective cover for a pediatric trocar, which includes an inner sleeve in a closed annular shape and an outer sleeve in a closed annular shape. The outer sleeve is located outside the inner sleeve. A lower port annular band is provided at the lower end of the inner sleeve, and an annular lower port airbag is provided inside the lower port annular band. An upper port annular band is provided at the upper end of the inner sleeve, and an annular upper port airbag is provided inside the upper port annular band. A rectangular inner sleeve window is provided on the side wall of the inner sleeve, and a left pressing band and a right pressing band are respectively provided on both sides of the inner sleeve window. The outer sleeve passes through between the left pressing band and the inner sleeve and between the right pressing band and the inner sleeve. The outer sleeve includes an opaque outer sleeve body, and two rectangular outer sleeve windows are provided on the outer sleeve body, and a transparent film is provided on one of the outer sleeve windows.

[0007] Preferably, a left strip airbag and a right strip airbag are respectively provided on both sides of the inner sleeve window on the inner wall of the inner sleeve.

[0008] Preferably, the lower port airbag, the upper port airbag, the left strip airbag and the right strip airbag are all film-type airbags and are provided with one-way inflation interfaces.

[0009] Preferably, a rigid frame is provided inside the inner sleeve window, and each side frame of the rigid frame is fixedly connected to the edge of the inner sleeve window.

[0010] Preferably, the inner sleeve and the outer sleeve are made of elastic fabric, the lower port annular band and the upper port annular band are made of non-elastic fabric, the top edge of the lower port annular band is welded and connected to the bottom edge of the inner sleeve, and the bottom edge of the upper port annular band is welded and connected to the top edge of the inner sleeve.

[0011] Preferably, the connection between each side frame of the rigid frame and the edge of the inner sleeve window and the connection between the edge of the transparent film and the edge of the corresponding outer sleeve window are both adhesive connections; the connection between the lower port airbag and the lower port annular band, the connection between the upper port airbag and the upper port annular band, and the connection between the left strip airbag and the right strip airbag and the inner sleeve are all adhesive connections.

[0012] The advantages and positive effects of the present utility model are as follows:

[0013] The present utility model provides a protective cover for a pediatric trocar with a reasonable structural design. Compared with the existing protective articles for protecting indwelling trocars, the trocar protective cover in the present utility model is a standardized consumable, which is convenient for medical staff to pick up according to needs and is convenient to wear on the child's limb after implanting the trocar, and can improve the standardization level of trocar protection operations. By setting the lower port airbag and the upper port airbag, the elastic airbag contacts with the child's limb and realizes wearing and fixing by relying on the elastic action of the airbag. Therefore, this protective cover has a proper tightness to avoid problems of falling off and pressure damage, and at the same time can improve the wearing comfort of the child.

[0014] The outer sleeve of this cannula protection cover can rotate and shift. When the outer sleeve window moves to the position aligned with the inner sleeve window, the indwelling cannula is exposed, and medical staff can operate on the cannula. When the transparent membrane moves to the position aligned with the inner sleeve window, medical staff can observe the internal cannula through the transparent membrane. When other opaque parts of the inner sleeve move to the position aligned with the inner sleeve window and completely cover the inner sleeve window, the cannula is blocked inside and cannot be observed from the outside. Therefore, the pediatric cannula protection cover in the present utility model can prevent children from seeing and touching the cannula when not observing and operating, and only need to move the position of the outer sleeve when observing and operating the cannula, that is, it does not affect medical staff's observation and operation of the indwelling needle during wearing, is convenient to operate, and reduces children's discomfort.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are given for detailed description.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , the pediatric cannula protection cover of the present utility model includes an inner sleeve 1 in a closed annular shape and an outer sleeve 5 in a closed annular shape. The outer sleeve 5 is located outside the inner sleeve 1, and the two are in a sleeved relationship. When this cannula protection cover is worn on a child's limb, the inner sleeve 1 and its accessory components no longer shift, and the outer sleeve 5 rotates and shifts as needed.

[0022] A lower port annular band 3 is provided at the lower end of the inner sleeve 1, and an annular lower port airbag 2 is provided inside the lower port annular band 3. An upper port annular band 7 is provided at the upper end of the inner sleeve 1, and an annular upper port airbag 6 is provided inside the upper port annular band 7. The functions of the lower port airbag 2 and the upper port airbag 6 are as follows: When this trocar protector is worn on a child's limb, the lower port airbag 2 is located between the lower port annular band 3 and the limb, and the upper port airbag 6 is located between the upper port annular band 7 and the limb. Relying on the elastic action of the airbags at the upper and lower positions, this trocar protector is worn and fixed on the child's limb. Therefore, this protector has an appropriate tightness to avoid problems of falling off and pressure damage. At the same time, the flexible airbag can improve the wearing comfort of the child.

[0023] In this embodiment, both the lower port airbag 2 and the upper port airbag 6 are film-type airbags and are provided with one-way inflation interfaces. Film-type airbags have currently been widely used in medical supplies such as airway intubation. The one-way inflation interface can also be called a one-way air valve and has a diaphragm inside. Therefore, both the lower port airbag 2 and the upper port airbag 6 can be controllably inflated. In this way, when this trocar protector is worn on a child's limb, when it is observed that the lower port airbag 2 and the upper port airbag 6 cannot form an appropriate combined state with the child's limb, air can be further injected into the airbag through the one-way inflation interface to make the airbag further expand. Specifically, a syringe can be used to draw air, and then the interface at the front end of the syringe is inserted into the one-way inflation interface, and the piston of the syringe is pressed. The increased external air pressure pushes open the internal diaphragm, and the air enters the airbag. When the air injection stops, the diaphragm resets to seal the one-way inflation interface.

[0024] In this embodiment, the lower port airbag 2 and the lower port annular band 3, and the upper port airbag 6 and the upper port annular band 7 are fixedly connected by bonding.

[0025] A rectangular inner sleeve window 10 is provided on the side wall of the inner sleeve 1. A left pressing band 8 and a right pressing band 4 are respectively provided on both sides of the inner sleeve window 10. The outer sleeve 5 passes through between the left pressing band 8 and the inner sleeve 1 and between the right pressing band 4 and the inner sleeve 1. In this embodiment, a rectangular rigid frame 9 is provided inside the inner sleeve window 10, and the respective side frames of the rigid frame 9 are fixedly connected to the edges of the inner sleeve window 10. Further, the respective side frames of the rigid frame 9 and the edges of the inner sleeve window 10 are adhesively connected. The function of setting the rigid frame 9 is to improve the ability of the inner sleeve window 10 to maintain its shape. When this trocar protector is worn on a child's limb, the inner sleeve window 10 should be located outside the indwelling trocar and the trocar should be located as much as possible in the middle position of the inner sleeve window 10.

[0026] In this embodiment, a left strip-shaped airbag 11 and a right strip-shaped airbag 12 are respectively provided on both sides of the inner sleeve window 10 on the inner wall of the inner sleeve 1, asFigure 2 As shown, both the left strip-shaped airbag 11 and the right strip-shaped airbag 12 extend along the axial direction of this protective sleeve. The functions of setting the left strip-shaped airbag 11 and the right strip-shaped airbag 12 are as follows: The part of the inner sleeve 1 between the left strip-shaped airbag 11 and the right strip-shaped airbag 12 is padded to a certain height, so that during the process of the outer sleeve 5 rotating and shifting, and during the process of the child's limb movement, the indwelling cannula located inside this protective sleeve is not easily touched.

[0027] In this embodiment, both the left strip-shaped airbag 11 and the right strip-shaped airbag 12 are film-type airbags and are provided with one-way inflation interfaces. Film-type airbags have currently been widely used in medical supplies such as airway intubation, etc. The one-way inflation interface can also be called a one-way air valve, and it has a diaphragm inside. Therefore, both the left strip-shaped airbag 11 and the right strip-shaped airbag 12 can be controllably inflated. In this way, when this cannula protective sleeve is worn on the child's limb, air can be further injected into the airbag through the one-way inflation interface to make the airbag further expand. Specifically, a syringe can be used to draw air, and then the interface at the front end of the syringe is inserted into the one-way inflation interface, and the piston of the syringe is pressed. The increased external air pressure pushes open the internal diaphragm, and the air enters the airbag. When the air injection stops, the diaphragm resets to seal the one-way inflation interface.

[0028] In this embodiment, both the left strip-shaped airbag 11 and the right strip-shaped airbag 12 are fixedly connected to the inner sleeve 1 by an adhesive bonding method.

[0029] The outer sleeve 5 includes an opaque outer sleeve body 5-1. Two rectangular outer sleeve windows 5-3 are provided on the outer sleeve body 5-1, and a transparent film 5-2 is provided on one of the outer sleeve windows. The edge of the transparent film 5-2 is adhesively connected to the edge of the corresponding outer sleeve window 5-3.

[0030] In this way, the outer sleeve 5 has three typical positions: one is the outer sleeve window 5-3, one is the transparent film 5-2, and the other is the other opaque part. By rotating and shifting the outer sleeve 5, the aforementioned three typical positions can be respectively moved to the outside of the inner sleeve window 10 of the inner sleeve 1. When the outer sleeve window 5-3 is aligned with the inner sleeve window 10, the cannula is exposed, and medical staff can perform operations. When the transparent film 5-2 is aligned with the inner sleeve window 10, medical staff can observe the cannula but cannot operate it. When the other opaque part is aligned with the inner sleeve window 10, the cannula cannot be observed or operated, and at this time, the child is simultaneously prevented from seeing and touching the indwelling cannula, playing a protective role.

[0031] In this embodiment, the inner sleeve 1 and the outer sleeve 5 are made of elastic fabric, that is, made of fabric with certain elasticity such as medical non-woven fabric, etc. The lower port ring band 3 and the upper port ring band 7 are made of non-elastic fabric, that is, made of fabric without elasticity such as canvas, etc. The top edge of the lower port ring band 3 is welded and connected to the bottom edge of the inner sleeve 1, and the bottom edge of the upper port ring band 7 is welded and connected to the top edge of the inner sleeve 1.

[0032] This protective cover is used as a standardized consumable and can be sealed in a sterile package at the factory for medical staff to take as needed.

[0033] Usage method:

[0034] Take out this trocar protective cover from the sterile package, pass the child's limb (such as the arm or leg) through the inner sleeve 1 until the protective cover moves to the indwelling position of the trocar. The trocar should be located approximately in the middle of the inner sleeve window 10. Then, inflate the lower port airbag 2, the upper port airbag 6, the left strip airbag 11 and the right strip airbag 12 as appropriate with a syringe. At this time, the trocar protective cover is worn and fixed on the child's limb, and the trocar is located inside the protective cover;

[0035] When the medical staff neither observes nor operates, rotate and displace the inner sleeve 5 until its opaque part moves to the outside of the inner sleeve window 10, and at this time, the inner sleeve window 10 and the trocar are blocked; when the medical staff needs to observe, rotate and displace the inner sleeve 5 until its transparent film 5-2 moves to the outside of the inner sleeve window 10; when the medical staff needs to operate the trocar, rotate and displace the inner sleeve 5 until its outer sleeve window 5-3 moves to the outside of the inner sleeve window 10.
