[0048] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0049] A type of puncture-resistant medical needle

[0050] This application discloses a puncture-resistant medical needle, such as... Figure 1 As shown, it includes a movable protective sleeve 1, a needle 2, a needle hub 3, and a tube body 4: the needle 2, needle hub 3, and tube body 4 are connected in sequence to form the needle body, as shown. Figure 2 As shown in (a), the movable protective sleeve 1 has a through-hole C-shaped hollow cylindrical structure or is as shown in (a). Figure 2 As shown in (b), the movable protective sleeve 1 has a C-shaped hollow cylindrical structure with the tail end connected. The movable protective sleeve 1 covers the needle body and can move along the needle body. The C-shaped notch of the movable protective sleeve 1 allows the butterfly wing 301 on the needle seat 3 to pass through.

[0051] This application makes full use of the needle protection sleeve in the prior art, changing the needle protection sleeve from a closed circular hollow structure to a through C-shaped hollow structure, and turning it into a movable protection sleeve 1. While achieving a simple structure, low cost and convenient operation, it can effectively reduce the occurrence of needlestick injuries.

[0052] In one embodiment, the medical needle includes a puncture needle.

[0053] In one embodiment, the range of movement of the movable protective sleeve 1 is limited to between the following two positions: Figure 3 As shown in (a), the movable protective sleeve 1 completely covers the position of the needle 2, and as shown in (a), the movable protective sleeve 1 completely covers the position of the needle 2. Figure 3 As shown in (b), the movable protective cover 1 covers the position of the needle holder 3. The above limitation is to reduce the possibility of loss due to excessive movement range of the movable protective cover 1.

[0054] In one embodiment, such as Figure 4 As shown, on the butterfly wing 301 of the needle holder 3, a number of holes 301.1 are provided near the needle body. The number of holes 301.1 are arranged in a direction parallel to the needle body. The number of holes 301.1 are used to provide a moving path for the C-shaped notch edge of the movable protective sleeve 1, so as to facilitate the movement of the movable protective sleeve 1 on the butterfly wing 301.

[0055] In one embodiment, such as Figure 5 As shown, a slide 5 is provided on the outer wall of the tube 4 connected to the needle seat 3, along the axial direction corresponding to the position of the butterfly wing 301. The slide is used to limit the movement of the movable protective sleeve 1 in the fixed track.

[0056] In one embodiment, the tail end of the slide 5 is provided with a fixing device 501.

[0057] In one embodiment, the slide 5 is elongated in the direction parallel to the needle body, and the longitudinal section of the front end of the slide 5 is V-shaped, with the bottom of the V-shape attached to the outer wall of the tube 4; the two sides of the V-shape are connected to the edges of the C-shaped notch, so that the movable protective sleeve 1 can move along the connection point; at the tail end of the slide 5, the middle part of the V-shape is filled, and the longitudinal section of the fixing device 501 is a solid columnar structure of inverted triangle or rectangle.

[0058] In one embodiment, the movable protective sleeve 1 has a buckle 502 at the front edge of the C-shaped notch to facilitate engagement with the edge of the slide rail 5.

[0059] In one embodiment, such as Figure 5 As shown, for the movable protective sleeve 1 with a through-hole C-shaped hollow cylindrical structure, the tail end of the movable protective sleeve 1 is provided with a limiting structure 101; the movable protective sleeve 1 can move along the butterfly wing 301 and the slide 5, and the distance that the limiting structure 101 moves backward is limited by the fixing device 501.

[0060] In one embodiment, for a movable protective sleeve 1 with a through-hole C-shaped hollow cylindrical structure, the limiting structure 101 at the tail edge of the C-shaped notch of the movable protective sleeve 1 consists of two symmetrical semi-cylindrical structures protruding toward the center line of the C-shaped notch.

[0061] In one embodiment, for a movable protective sleeve 1 with a through-hole C-shaped hollow cylindrical structure, there is a protrusion (not shown in the figure) at the connection between the needle and the needle seat along the path of its C-shaped notch, thereby blocking the limiting structure 101 to prevent the movable protective sleeve 1 from moving forward beyond the position of the needle 2.

[0062] In one embodiment, for a movable protective sleeve 1 with a C-shaped hollow cylindrical structure connected at the tail end, when it moves forward, the tail end connection is blocked by the butterfly wing 301. Without needing more protruding structures to block it, it can also prevent the movable protective sleeve 1 from moving forward beyond the position of the needle 2. When the tail end connection of the movable protective sleeve 1 is blocked by the butterfly wing 301, the length of the movable protective sleeve 1 is also sufficient to completely cover the needle 2.

[0063] In one embodiment, the front section of the tube body 4 connected to the needle seat 3 is a rigid tube body 401, and the rear section is a flexible tube 402. The rearward movement range of the movable protective sleeve 1 does not exceed the rigid tube body 401.

[0064] Method of using a puncture-proof medical needle

[0065] On the other hand, this application also discloses a method of using a puncture-resistant medical needle, employing a medical needle as described above, such as... Figure 1 As shown, in the protective state before the medical needle is used, the movable protective cover 1 is positioned to completely cover the needle tip 2;

[0066] When the medical needle is in use, move the movable protective cover 1 to cover the needle hub 3;

[0067] After the medical needle is used, move the movable protective cover 1 to a position that completely covers the needle 2 to achieve a protective state.

[0068] A puncture-proof intravenous infusion needle and its usage method

[0069] In one embodiment, the medical needle includes an intravenous infusion needle, and the tube body includes an infusion tubing. The intravenous infusion needle in this application may also adopt a design such as several holes (301.1) or a slide (5) as described above, so as to effectively reduce the occurrence of needlestick injuries during infusion.

[0070] In one embodiment, the movable protective sleeve 1 has a protruding limiting structure 101 or is connected to the tail end. Holes can be drilled in the needle body butterfly 301 and a slide rail 5 can be added to change the way infusion needles are used in the past. When in use, the movable protective sleeve 1 is pulled back to the needle seat 3 to expose the needle body. After the infusion needle is used up, the movable protective sleeve 1 is pulled forward to return to its original position. When the patient is receiving infusion, the fixing device 501 can ensure that the movable protective sleeve 1 will not slide out of the limited range during use. The slide rail 5 can ensure that the protective sleeve slides and is fixed in the predetermined track when sliding, and will not come off or derail from the needle seat, so as not to affect the patient's infusion process.

[0071] A puncture-proof venous blood collection needle and its usage method

[0072] In one embodiment, the medical needle includes a venous blood collection needle, and the tube body includes a blood collection tube. The venous blood collection needle in this application may also adopt a design such as several holes (301.1) or a slide (5) as described above, so as to effectively reduce the occurrence of needlestick injuries during blood collection.

[0073] In one embodiment, such as Figure 6 As shown in (a), in the protective state before use of the venous blood collection needle, the movable protective sleeve 1 is positioned to completely cover the needle tip 2; the movable protective sleeve 1 has a protruding limiting structure 101 or is connected to the tail end, and holes can be drilled in the needle body flap 301 and slide rails 5 can be added to change the way the blood collection needle is used in the past, so that it can be used as follows. Figure 6 As shown in (b), the movable protective sleeve 1 is pulled back to the needle seat 3 to expose the needle body. After the infusion needle is used, the movable protective sleeve 1 is pulled forward to return to its original position. When the patient is drawing blood, the fixing device 501 can ensure that the movable protective sleeve 1 will not slide out of the limited range during use. The slide rail 5 can ensure that the protective sleeve slides and is fixed in the predetermined track, and will not fall off or derail from the needle seat, so as not to affect the patient's blood drawing process.
