[0067] Combination Figure 1-Figure 6 As shown;

[0068] The present invention provides an anti-puncture recovery device 1000 for an infusion needle 2000, comprising a needle recovery component 10 and a needle puncture cotton block 20;

[0069] Among them, the needle recovery part 10 is formed into a rectangular structure and is arranged along the front-to-back direction. The upper part thereof is provided with an infusion tube passing channel 101 that passes through its front and rear end faces along the front-to-back direction. The lower part of its front end face is provided with a needle accommodating cavity 102 extending to its rear lower part. The size of the needle piercing cotton block 20 is adapted to the size of the needle accommodating cavity 102, and is clamped in the needle accommodating cavity 102 with an interference fit.

[0070] Based on the above, it is clear that, when the present application is implemented, it is mainly used as an anti-puncture recovery device 1000 for an infusion needle 2000.

[0071] The present invention is sleeved on the outside of the infusion tube when in use, and includes a needle recovery part 10 of a rectangular structure and a needle penetration cotton block 20 clamped in the needle accommodating cavity 102 therein. Obviously, the size of the present application during design is at least twice the size of the infusion tube. Therefore, the size of the needle accommodating cavity 102 of the present application is also large, so that even if the used infusion needle 2000 is not completely aligned with the center of the needle accommodating cavity 102, it can be easily inserted therein and penetrated into the needle penetration cotton block 20 clamped therein and fixed. The infusion needle 2000 is easy to insert and the insertion is time-saving and labor-saving, and the insertion fixation is good and the anti-slip property is good, so that it is not easy to prick the hands of medical staff due to deviation of insertion, thereby greatly reducing the probability of related cases of infusion needle 2000 puncture and cross infection of blood.

[0072] Furthermore, the present invention is pre-mounted on the outside of the infusion tube when it is packaged at the factory, and is used together with the traditional infusion tube so that it will not be lost.

[0073] Furthermore, the present application is highly practical and has good use effect.

[0074] Preferably, in the present technical solution, the inner diameter of the needle accommodating cavity 102 gradually decreases from front to back to form a trumpet-shaped structure.

[0075] As a result, the front end opening of the needle accommodating cavity 102 is made larger, making it easier to insert the used infusion needle 2000 therein.

[0076] Furthermore, in a specific implementation, the present application also includes the needle piercing the rubber block 30;

[0077] The needle piercing rubber block 30 is formed into a flat structure and is fixedly arranged at the lower part of the front end surface of the needle recovery member 10 to seal and cover the needle accommodating cavity 102 .

[0078] Since the present application also includes a needle penetration rubber block 30 fixedly arranged at the lower part of the front end surface of the needle recovery part 10 to seal and cover the needle accommodating cavity 102, the hardness of the needle penetration rubber block 30 is harder than that of the needle penetration cotton block 20. While facilitating the insertion of the used infusion needle 2000, it can also further play a role in fixing the used infusion needle 2000, so that the used infusion needle 2000 is less likely to slip out of the needle accommodating cavity 102 described in the present application, making the use of the present application safe and reliable.

[0079] Preferably, in this embodiment, a concave step 103 is cut backwards around the periphery of the opening of the needle accommodating cavity 102 at the lower portion of the front end surface of the needle recovery member 10 ; the needle piercing rubber block 30 is clamped and adhered to the concave step 103 .

[0080] Therefore, the needle pierces the rubber block 30 to be firmly fixed and not easily displaced.

[0081] Preferably, in this embodiment, the needle piercing rubber block 30 is made of soft plastic material or soft silicone material to make the texture soft, so that the used infusion needle 2000 can be easily inserted through it.

[0082] Furthermore, in a specific implementation, the present application further includes a plurality of left needle pressing and bending members 40 and a plurality of right needle pressing and bending members 50;

[0083] The left end surface of the needle recovery member 10 is evenly vertically opened with a plurality of left pressing grooves 104 penetrating the needle accommodating cavity 102 from front to back; the right end surface of the needle recovery member 10 is evenly vertically opened with a plurality of right pressing grooves 105 penetrating the needle accommodating cavity 102 from front to back;

[0084] The multiple right pressing grooves 105 are staggeredly distributed with the multiple left pressing grooves 104; the right ends of the multiple left needle pressing and bending parts 40 can be movably inserted into the multiple left pressing grooves 104; the left ends of the multiple right needle pressing and bending parts 50 can be movably inserted into the multiple right pressing grooves 105.

[0085] From the above, it can be clearly seen that the present application also includes a plurality of left needle pressing and bending parts 40 that can be moved left and right and inserted into the left side of the needle accommodating cavity 102, and a plurality of right needle pressing and bending parts 50 that can be moved left and right and inserted into the right side of the needle accommodating cavity 102. The plurality of left needle pressing and bending parts 40 and the plurality of right needle pressing and bending parts 50 are also staggeredly distributed.

[0086] Therefore, after inserting the used infusion needle 2000 into the needle accommodating cavity 102, the lower half of the needle recovery part 10 is held by hand to hold the multiple left needle pressing and bending parts 40 and the multiple right needle pressing and bending parts 50 towards each other, and the multiple left needle pressing and bending parts 40 and the multiple right needle pressing and bending parts 50 will bend the used infusion needle 2000 in a dislocated manner to destroy the used infusion needle 2000 and prevent it from being illegally used a second time, so that the infusion needle 2000 has good self-destructive properties and is less likely to slip out of the needle accommodating cavity 102 described in the present application after being bent, so that the use effect of the present application is better.

[0087] And preferably, in the present technical solution, the left and right lengths of the multiple left needle pressing and bending parts 40 and the left and right lengths of the multiple right needle pressing and bending parts 50 are slightly smaller than the left and right widths of the needle accommodating cavity 102; the upper and lower heights of the multiple left needle pressing and bending parts 40 and the upper and lower heights of the multiple right needle pressing and bending parts 50 are slightly smaller than the upper and lower heights of the needle accommodating cavity 102 at the corresponding positions.

[0088] At the same time, in the present technical solution, each of the left needle pressing and bending members 40 comprises a left needle pressing and bending block 401 and a left flat stopper 402 connected to the right end of the left needle pressing and bending block 401 and having an outer diameter slightly larger than the outer diameter thereof; a plurality of the left flat stopper ears 402 are correspondingly fixed to the inner peripheries of a plurality of the left pressing grooves 104;

[0089] Moreover, in the present technical solution, each of the right needle pressing and bending parts 50 includes a right needle pressing and bending block 501 and a right flat limiting ear 502 connected to the left end of the right needle pressing and bending block 501 and having an outer diameter slightly larger than its outer diameter; a plurality of the right flat limiting ears 502 are correspondingly fixed to the inner periphery of a plurality of the right pressing grooves 105.

[0090] From the above, it can be foreseen that when assembling the present application, the plurality of left needle pressing and bending members 40 are first sent into the appropriate position from the cavity opening of the needle accommodating cavity 102, and then the left needle pressing and bending blocks 401 of the plurality of left needle pressing and bending members 40 are extended from the corresponding positions of the left pressing grooves 104, so that the left flat limiting ears 402 of the plurality of left needle pressing and bending members 40 are correspondingly pressed against the inner periphery of the plurality of left pressing grooves 104, and the plurality of right needle pressing and bending members 50 are sent into the appropriate position from the cavity opening of the needle accommodating cavity 102, and then the right needle pressing and bending blocks 501 of the plurality of right needle pressing and bending members 50 are extended from the corresponding positions of the right ... and the left flat limiting ears 402 of the plurality of left needle pressing and bending members 40 are correspondingly pressed against the inner periphery of the plurality of left pressing grooves 104, and the left flat limiting ears 402 of the plurality of left needle pressing and bending members 40 are extended from the corresponding positions of the right pressing grooves 104, and the left flat limiting ears 402 of the plurality of left needle pressing and bending members 40 are extended from the corresponding positions of the left pressing grooves 104, and the left flat limiting ears 402 of the plurality of left needle pressing and bending members 40 are extended from the corresponding positions of the 05 is extended so that the right flat limiting ears 502 of the multiple right needle pressing and bending parts 50 correspond to the inner circumference of the multiple right pressing grooves 105, and then the needle insertion cotton block 20 is flattened and inserted into the needle accommodating cavity 102 from the cavity opening, and then the needle insertion cotton block 20 is released to make it elastically recover, and its left side surface can press against the multiple left flat limiting ears 402 of the left needle pressing and bending parts 40 to the inner circumference of the multiple left pressing grooves 104, and its right side surface can press against the multiple right flat limiting ears 502 of the right needle pressing and bending parts 50 to the inner circumference of the multiple right pressing grooves 105, and finally the needle insertion rubber block 30 is clamped and adhered to the recessed step 103.

[0091] Through the above-mentioned assembly, the multiple left needle pressing and bending parts 40 and the multiple right needle pressing and bending parts 50 of the present application can be well tightened and fixed, so that no fastening screws or other fixing parts are required, making the assembly of the present application convenient.

[0095] Specifically, in the present technical solution, the right anti-needle-stick baffle 70 includes a right baffle A701 whose upper end face is inclined toward the rear and downward direction, a right baffle B702 connected to the upper front part of the right baffle A701, and a right baffle C703 connected to the lower rear part of the right baffle A701; the right baffle A701 is located on the upper part of the multiple right needle pressing and bending parts 50 and is adjacent to the multiple right needle pressing and bending parts 50.

[0096] From the above, it should be noted that, when using the present application, the medical staff holds the upper part of the needle recovery part 10 with one hand, and holds the used infusion needle 2000 with the other hand and inserts it into the needle accommodating cavity 102 of the lower part of the needle recovery part 10.
