Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a special needle with a height-adjustable support pad. Background Technology

[0002] When using a special needle, to ensure that it is inserted fully, the effective length of the special needle is always greater than the sum of the length of the skin and the puncture channel of the infusion port. However, this will cause the needle handle to be about 2mm higher than the skin. Currently, the support pad of the special needle can only be adjusted before use. Therefore, doctors and nurses will fold a fairly thick gauze and place it between the needle handle and the skin to maintain the stability of the special needle. On the one hand, this is time-consuming and laborious. On the other hand, the gauze used for padding varies in size and thickness depending on different people's understanding, and there is no uniform standard. It is easy to shift, which increases the difficulty of care for nurses and patients.

[0003] In addition, the foam padding of the support pad of existing special needles generally uses a large area of ​​closed-cell foam. The support pad is not breathable, and patients will feel hot and humid and uncomfortable, resulting in poor comfort.

[0004] This application is filed to address the aforementioned deficiencies. Utility Model Content

[0005] The purpose of this invention is to provide a special needle with a height-adjustable support pad, which solves the problems of time-consuming and laborious placement of gauze between the needle handle and the skin, as well as the easy displacement of the needle. It also solves the problem of poor breathability of traditional support pads by using a material with better breathability.

[0006] To address the aforementioned problems, this utility model provides a special needle with a height-adjustable support pad, comprising a needle head, a support pad assembly, and a height adjustment assembly. The support pad assembly includes a lifting body and a base pad connected to the lifting body. The base pad is made of a small area of ​​foam or a breathable material to improve breathability and comfort. The height adjustment assembly is connected between the needle tube and the fixed wing, and is connected to the lifting body via a threaded or sliding connection. In the height-adjusted state, the height of the support pad assembly is adjusted by adjusting the relative position between the height adjustment assembly and the lifting body, allowing the support pad assembly to contact and support the skin, thereby improving the stability of the special needle.

[0007] According to one embodiment of the present invention, the height adjustment component includes a threaded column, the lifting body includes a lifting plate, and the center of the lifting plate is provided with a threaded hole that mates with the threaded column. The lifting effect is achieved by rotating the lifting plate.

[0008] According to one embodiment of the present invention, the height adjustment component includes a disc body, the outer circular surface of the disc body is provided with a thread, the lifting body includes a lifting ring, the inner wall of the lifting ring and the outer circular surface of the disc body are connected by a threaded engagement, and the lifting effect is achieved by rotating the lifting ring. In this method, since the lifting ring is located on the periphery of the disc body, the contact area between the two is large, and the stability during lifting is better.

[0009] According to one embodiment of the present invention, the lifting body is provided with a plurality of ventilation holes to assist the ventilation of the base pad, thereby further ensuring breathability and comfort.

[0010] According to one embodiment of the present invention, the diameter of the vent hole is 1~3mm, and the vent holes are preferably distributed in a ring shape on the lifting body.

[0011] According to one embodiment of the present invention, the breathable material is a breathable sponge, which can be an ordinary sponge or a sponge with antibacterial and anti-inflammatory properties.

[0012] According to one embodiment of the present invention, a fixing wing is installed on the needle head for fixing assistance after the special needle is inserted into the human body.

[0013] According to one embodiment of the present invention, the outer surface of the lifting body is provided with an anti-slip structure, such as anti-slip protrusions or anti-slip textures, to facilitate the rotation operation of the lifting body.

[0014] According to one embodiment of the present invention, the height adjustment component is provided with a limit structure to limit the maximum descent distance of the support pad component.

[0015] The beneficial effects of this invention are that by setting up a support pad assembly and a height adjustment assembly, after the special needle is inserted into the human body, medical staff can adjust the height of the support pad assembly by rotating the lifting body to make the bottom pad contact the skin, thereby stabilizing the special needle. The operation is convenient and quick, eliminating the need to add gauze to stabilize the special needle, reducing the difficulty of use and care for doctors and nurses. The bottom pad uses small-area foam or other medical materials such as medical polyurethane with good breathability and support, with perforated breathable sponge to achieve the same breathability as gauze. With the ventilation holes, moisture can diffuse more easily, increasing patient comfort, especially improving the comfort of patients who use the device for extended periods in the same location.

[0023] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0024] Example 1:

[0025] A special needle with a height-adjustable support pad; the special needle in this solution can be a safety-type special needle or a general-purpose special needle.

[0026] like Figure 1 It includes a needle head 1, a support pad assembly 2, a catheter 3, and a height adjustment assembly.

[0027] The needle head 1 includes a curved needle tube structure and a fixing wing 5 connected to the needle tube structure. The fixing wing 5 is used for holding and inserting the special needle and for fixing it after it is inserted into the human body.

[0028] The support pad assembly 2 includes a lifting body and a base pad 22 connected to the lifting body. The base pad 22 is annular and made of a breathable and elastic material, such as a breathable sponge material like polyurethane with added antibacterial substances. This improves breathability and comfort while also providing antibacterial and anti-inflammatory effects. The base pad 22 can be connected to the lifting body by adhesive or snap-fit. To further improve breathability and comfort, the lifting body is provided with several ventilation holes to assist the ventilation of the base pad 22, allowing moisture inside the sponge of the base pad 22 to diffuse to the outside, keeping the patient dry and comfortable during use. The diameter of the ventilation holes is 1~3mm, and the ventilation holes are preferably distributed in a ring on the lifting body.

[0029] The outer surface of the lifting body is equipped with an anti-slip structure, such as anti-slip protrusions 25 and anti-slip textures, to facilitate the rotation operation of the lifting body.

[0030] Preferably, the ventilation holes are opened at the anti-slip protrusion 25 and open to both sides of the anti-slip protrusion 25 to prevent the ventilation holes from being closed when the lifting body is covered with material, thus affecting the ventilation effect.

[0031] Optionally, the base pad 22 is detachably connected to the lifting body, and base pads 22 of different thicknesses, materials and sizes can be replaced as needed to suit different placement situations.

[0032] The height adjustment component is connected to the needle head 1. The connection method can be adhesive, snap-fit, etc. The height adjustment and the lifting body are connected by a threaded connection. In the height adjustment state, the support pad component 2 achieves height adjustment by the relative rotation between the height adjustment component and the lifting body, so that the support pad component 2 contacts the skin for support and improves the stability of the special needle.

[0033] In this embodiment, as Figure 2 , Figure 3 The height adjustment component includes a threaded post 41, and the lifting body includes a lifting plate 21. The center of the lifting plate 21 is provided with a threaded hole that mates with the threaded post 41. The lifting effect is achieved by rotating the lifting plate 21.

[0034] Preferably, such as Figure 2 A limiting structure 43 is provided on the threaded post 41. The limiting structure 43 is an annular protrusion provided at the bottom of the threaded post 41, which is used to limit the maximum descent distance of the support pad assembly 2.

[0035] After the special needle is inserted into the human body, medical staff adjust the height of the support pad assembly by rotating the lifting body, so that the bottom pad 22 contacts the skin, achieving the effect of stabilizing the special needle. The operation is convenient and quick, eliminating the need to add gauze to stabilize the special needle, reducing the difficulty of use and care for doctors and nurses. The bottom pad uses a porous, breathable sponge made of medical polyurethane or other medical materials with good breathability and support, achieving the same breathability as gauze. With the ventilation holes, moisture can be diffused more easily, increasing patient comfort. The combination of these two can overcome the drawbacks of using the current special needle, making it simple and convenient for patients to use. It is suitable for indwelling in different sites and for different times, especially improving the comfort of patients using it in the same site for a very long time, while greatly improving the stability during use.

[0036] Example 2:

[0037] Unlike in Example 1, in this example, as Figures 4-6The height adjustment component includes a disc body 42, which is snapped or glued to the fixed wing 5 and optionally connected to the needle head 1. The outer circular surface of the disc body 42 is provided with threads. The lifting body includes a lifting ring 23, and the inner wall of the lifting ring 23 is connected to the outer circular surface of the disc body by a threaded fit. The lifting effect is achieved by rotating the lifting ring 23. In this method, since the lifting ring 23 is located on the periphery of the disc body 42, the contact area between the two is large, and the stability during lifting is better.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
