Description

Technical Field

[0001] This invention relates to the field of implantation needle technology, and more particularly to a safe subcutaneous implantation needle. Background Technology

[0002] Currently, butterfly needles are widely used in medical practice, such as for injections and blood collection. Because the needle is often exposed after use, the operator's fingers are easily pricked, leading to accidental punctures and increasing the risk of infection. In particular, butterfly needles are typically secured to the patient's skin with medical tape during use. After use, the tape needs to be removed, and the exposed needle is especially prone to accidental punctures during the tape removal process, making disposal very difficult. To prevent accidental punctures and facilitate disposal, butterfly needle components that allow the needle to retract after use have been proposed.

[0003] However, existing implantation needles have the following drawbacks:

[0004] (1) The existing anti-puncture components are generally complex in structure, which increases production costs. Utility Model Content

[0005] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a safe subcutaneous implantation needle that can protect the needle tip, with a simple structure and convenient operation.

[0006] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0007] A safe subcutaneous implantation needle includes a soft tube, a connecting needle tube connected to the outlet end of the soft tube, a needle tip vertically connected to the outlet end of the connecting needle tube, a sleeve fixedly fitted onto the connecting needle tube, and a protective member connected to the top of the sleeve, the protective member being able to cover the needle tip; the protective member includes an open protective shell connected to the top of the sleeve, a vertical rod fixedly installed inside the top of the open protective shell, and a clamping plate obliquely fixedly installed at the bottom of the vertical rod, the needle tip being able to be engaged between the clamping plate and the vertical rod.

[0008] Furthermore, both the protective components and the sleeves are made of plastic.

[0009] Furthermore, two butterfly wings are symmetrically arranged on the front and back of the block.

[0010] Furthermore, the hose is provided with a liquid-stopping device, which includes an open ring, two through ports opened on the open ring for the hose to pass through, a clamping connector fixedly installed at the top left end of the open ring, a clamping block fixedly installed at the top right end of the open ring and engaged with the clamping connector, a compression block one fixedly installed at the bottom of the clamping block, and a compression block two fixedly installed at the top inside the open ring and corresponding to the compression block one. The hose can be compressed by the compression block one and the compression block two.

[0011] Furthermore, the entire liquid-stopping component is made of plastic.

[0012] Furthermore, the connecting pipe is screwed with a sealing cap, which seals the outlet end of the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) When in use, by folding the opening protective shell, the opening protective shell drives the card plate and the pull rod to move, and finally the needle tip is limited between the card plate and the upright, thus achieving protection of the needle tip. The structure is simple, the operation is convenient, and the production cost can be reduced. Compared with the existing technology, it solves the technical problem that the existing anti-puncture component structure is generally complex and increases the production cost.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the preceding and following objects as a type of safe subcutaneous implantation needle.

[0021] Example 1:

[0022] like Figures 1-2 As shown, this embodiment provides a safe subcutaneous implantation needle, which includes a tubing 3, a connecting needle tube 18 connected to the outlet end of the tubing 3, a needle tip 6 vertically connected to the outlet end of the connecting needle tube 18, a sleeve 4 fixedly sleeved on the connecting needle tube 18, and a protective member 1 connected to the top of the sleeve 4. The protective member 1 can cover the needle tip 6. The protective member 1 includes an open protective shell 5 connected to the top of the sleeve 4, a vertical rod 14 fixedly installed inside the top of the open protective shell 5, and a retaining plate 15 obliquely fixedly installed at the bottom of the vertical rod 14. The needle tip 6 can be engaged between the retaining plate 15 and the vertical rod 14.

[0023] A safe subcutaneous implantation needle includes a flexible tube 3, with a connecting needle tube 18 connected to the outlet end of the flexible tube 3. A needle tip 6 is vertically connected to the outlet end of the connecting needle tube 18. A sleeve block 4 is fixedly fitted onto the connecting needle tube 18, and a protective component 1 is connected to the top of the sleeve block 4, which covers the needle tip 6. The protective component 1 includes an open protective shell 5 connected to the top of the sleeve block 4. A vertical rod 14 is fixedly installed at the top inside the open protective shell 5, and a retaining plate 15 is fixedly installed at an angle at the bottom of the vertical rod 14, allowing the needle tip 6 to be engaged between the retaining plate 15 and the vertical rod 14. In use, by folding the open protective shell 5, the open protective shell 5 moves the retaining plate 15 and the pull rod, ultimately confining the needle tip 6 between the retaining plate 15 and the vertical rod 14, thus providing protection for the needle tip 6. The structure is simple, the operation is convenient, and the production cost is reduced. Compared with existing technologies, it solves the technical problem that the existing anti-puncture component structures are generally complex and increase production costs.

[0024] Furthermore, both the protective component 1 and the sleeve block 4 are made of plastic. By using this method, the soft plasticity of the plastic material allows the opening protective shell to rotate on the sleeve block 4, and at the same time, the position of the opening protective shell can be adjusted so that the needle tip 6 is limited between the card plate 15 and the upright 14, thereby improving practicality.

[0025] Furthermore, the sleeve 4 is symmetrically provided with two butterfly wings 7, which allows the two butterfly wings 7 to come into contact with the skin, thus helping to improve the limiting of the needle tip 6.

[0026] Furthermore, the hose 3 is provided with a liquid-stopping element 2, which includes an open ring 8, two through ports 9 opened on the open ring for the hose 3 to pass through, a clamping connector 10 fixedly installed at the top left end of the open ring 8, a clamping block 11 fixedly installed at the top right end of the open ring 8 and engaged with the clamping connector 10, a compression block 12 fixedly installed at the bottom of the clamping block 11, and a compression block 2 13 fixedly installed at the top inside the open ring 8 and corresponding to the compression block 12. The hose 3 can be compressed by the compression block 12 and the compression block 2 13.

[0027] Without this technical solution, the following problems may occur: it is inconvenient to quickly stop the liquid flowing in the hose 3.

[0028] The hose 3 is equipped with a liquid-stopping element 2, which includes an open ring 8 with two through-holes 9 for the hose 3 to pass through. A clamping connector 10 is fixedly installed at the top left end of the open ring 8, and a clamping block 11 that engages with the clamping connector 10 is fixedly installed at the top right end of the open ring 8. A compression block 12 is fixedly installed at the bottom of the clamping block 11, and a compression block 2 13 corresponding to the compression block 12 is fixedly installed at the top inside the open ring 8. The hose 3 can be compressed by the compression block 12 and the compression block 2 13. In use, by pressing down on the clamping block 11, the clamping block 11 moves the compression block 12 downward, clamping the hose 3 between the compression block 12 and the compression block 2 13. Then, the clamping block 11 engages with the clamping connector 10, thereby quickly clamping the hose 3. Compared with the prior art, this solves the technical problem of inconvenient quick stopping of the liquid flowing in the hose 3.

[0029] Furthermore, the liquid-stopping component 2 is entirely made of plastic. By using this method, the elasticity of the plastic can be utilized to press the liquid-stopping component 2.

[0030] Furthermore, a sealing cap 17 is screwed onto the connecting pipe 16, which seals the outlet end of the connecting pipe 16. This method also seals the inlet end of the connecting pipe 16.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
