Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to an anti-pressure injury indwelling needle. Background Art

[0002] Clinically, after the indwelling needle is inserted into the human body, in order to fix the indwelling needle to reduce the secondary injury that may be caused by the movement of the indwelling needle, nowadays, a film is mostly used, that is, the film is directly covered on the surface of the indwelling needle to achieve the effect of fixing the indwelling needle.

[0003] While achieving the fixing effect in the above way, in order to ensure the fixing effect, the indwelling needle generally needs to be pressed tightly. The handle part of the indwelling needle is made of hard material, and the wearing time of the indwelling needle is also long. Therefore, it is easy to cause damage to the pressing area. At the same time, since the handle is cylindrical, it is easy to generate an air pocket near the contact area with the skin, resulting in a poor wrapping effect and easy sliding of the handle part, and the fixing effect is poor. Therefore, it needs to be improved. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an anti-pressure injury indwelling needle that can effectively avoid skin damage and improve the fixing effect at the same time.

The dislocation area is connected with a second wrapping area in the direction of the first wrapping area. The first wrapping area and the second wrapping area are mutually dislocated along the cut to wrap the upper and lower sides of the needle handle respectively. A deformation cavity is formed in the second wrapping area and a fluid is filled in the deformation cavity.

[0008] As a further improvement of the utility model, the thickness of the second wrapping area gradually decreases from the end close to the dislocation area to the end far from the dislocation area.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0024] like Figures 1-5As shown in the figure, an indwelling needle for preventing pressure injury includes a needle body unit 1, and the needle body unit 1 includes a needle tip 2 and a needle handle 3.

[0025] It further includes a film unit 4. The film unit 4 is used to wrap and cover the needle body unit 1 and fix the needle body unit 1 to the human body. The film unit 4 forms an incision 5 corresponding to the end of the needle handle 3 and forms a first wrapping area 6 and a dislocation area 7 on both sides of the incision 5. Specifically, the first wrapping area 6 is the side where the incision 5 is close to the center of the film unit 4. The dislocation area 7 is connected with a second wrapping area 8 in the direction of the first wrapping area 6. The first wrapping area 6 and the second wrapping area 8 are misaligned along the incision 5 to wrap the upper and lower sides of the needle handle 3 respectively. A deformation cavity 9 is formed in the second wrapping area 8 and a fluid is filled in the deformation cavity 9. In this embodiment, the fluid is specifically gas.

[0026] During use, after connecting the needle body unit 1 to the human body, only the needle handle 3 remains on the human body surface at this time. Further misalign the first wrapping area 6 and the dislocation area 7 so that the first wrapping area 6 and the second wrapping area 8 form an annular structure, and make the annular structure sleeved to wrap one end of the needle handle 3 away from the needle tip 2, and make the deformation cavity 9 located under the needle handle unit, that is, between the needle handle 3 and the human body. Then, after the rest of the film unit 4 is attached, the needle handle 3 presses on the deformation cavity 9, causing the deformation cavity 9 to deform, and realizing the soft contact between the needle handle 3 and the human body, thereby avoiding the hard material of the needle handle 3 itself from causing pressure injury to the human body.

[0027] At the same time, due to the existence of the deformation cavity 9, the second wrapping area 8 can obtain greater deformation ability compared with traditional soft materials. At the same time, the filling of the fluid can ensure the support effect of the deformation cavity 9 itself to ensure the isolation effect between the needle handle 3 and the human body.

[0028] Preferably, the thickness of the second wrapping area 8 gradually decreases from the end close to the dislocation area 7 to the end far from the dislocation area 7.

[0029] By setting the thickness of the second wrapping area 8, the needle handle 3 can be kept in an inclined state relative to the human body surface after the film unit 4 is attached to the needle handle 3, thereby adapting to the needle insertion route and avoiding pulling the needle tip 2 to cause pain.

[0030] Preferably, the second wrapping area 8 includes a pressure reduction layer 10 in the middle section and connection surfaces 11 on both sides of the pressure reduction layer 10. The two connection surfaces 11 are used to cooperate with the first wrapping area 6 to wrap the needle handle 3 in a ring shape. The thickness of the pressure reduction layer 10 is greater than that of the two connection surfaces 11. The deformation cavity 9 corresponds to the pressure reduction layer 10. An adhesion surface 12 is formed on one side of the pressure reduction layer 10 and is used to adhere to the human body.

[0031] The adhesion of the pressure reduction layer 10 to the human body can prevent the pressure reduction layer 10 itself from sliding relative to the human body, thereby cooperating with the film unit 4 to ensure the fixing effect on the needle handle 3.

[0032] Preferably, thin-wall regions 13 are formed on both sides of the voltage-reducing layer 10, and the thin-wall regions 13 are used for deforming outward when the deformation cavity 9 is pressed.

[0033] By providing the thin-wall regions 13, the deformation direction of the deformation cavity 9 when pressed can be guided, so as to improve the stability after the needle handle 3 is installed. At the same time, the provision of the thin-wall regions 13 can also further improve the deformation ability of the deformation cavity 9.

[0034] Preferably, the film-applying unit 4 includes a transparent tape portion 14 and an annular belt 15 disposed around the tape portion 14. The cut 5 corresponds to the annular belt 15, and the tape portion 14 is used for wrapping and fixing the needle handle 3 and the voltage-reducing layer 10.

[0035] Through the transparent tape portion 14, medical staff can observe the puncture site. At the same time, the wrapping of the tape portion 14 around the needle handle 3 and the voltage-reducing layer 10 can relatively fix the needle handle 3 and the voltage-reducing layer 10, so as to further reduce the slippage of the needle handle 3 relative to the voltage-reducing layer 10, thereby improving the stability after the needle handle 3 is installed.

[0036] Preferably, a thin-sheet-shaped connecting portion 16 is formed at one end of the second wrapping region 8 close to the misalignment region 7, and the misalignment region 7 is connected through the connecting portion 16.

[0037] By providing the connecting portion 16, when disassembling, the annular belt 15 and the tape portion 14 at other positions can be peeled off first. Further, by cutting off the connecting portion 16, the second wrapping region 8 is separated from the tape unit, so that the tape unit is withdrawn from the human body along with the indwelling needle. Finally, the second wrapping region 8 is disassembled. By the above method, it is possible to avoid the defect of difficult disassembly caused by the position of the second wrapping region 8 and the adhesion between the second wrapping region 8 and the human body during disassembly.

[0038] Preferably, a break-off cut 5 is provided on the connecting portion 16.

[0039] By providing the break-off cut 5, the cutting and separation of the connecting portion 16 can be facilitated, thereby facilitating use.

[0040] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
