Description

Technical Field

[0001] The utility model relates to the technical field of blood collection needles, in particular to a disposable blood collection needle. Background Art

[0002] A lancet is a medical device used to collect blood samples, typically consisting of a sharp needle, a pinch-grip handle, and a peelable pick.

[0003] The needles of existing blood collection needles cannot be completely hidden after use, and there is blood residue, which increases the risk of other people coming into contact with the blood on the needle, leading to the spread of infectious diseases. At the same time, blood collection needles that are not handled in time have the risk of accidentally stabbing other people or yourself, increasing the occurrence of stabbing accidents.

[0004] The existing blood collection needle has the following disadvantages after use: after the blood collection is completed, the needle of the blood collection needle is exposed, which is easy to be confused and used again, and the needle after blood collection accidentally contacts others, causing infection risks. To this end, we propose a disposable blood collection needle. Utility Model Content

[0008] The needle handle assembly comprises a needle handle, a needle groove, a protruding block and a recess.

[0009] Furthermore, the recess is formed at the bottom end of the needle handle, a needle groove is formed at the top of the recess, and raised blocks are provided on both sides of the bottom of the needle groove.

[0010] Furthermore, the needle assembly includes a needle and an annular recess, the annular recess is provided in two groups, the two groups of annular recesses are respectively opened in the middle of the needle, the annular recess is provided in two groups, the two groups of annular recesses are respectively opened in the middle of the needle, and the top end of the needle is inserted in the needle groove.

[0011] Furthermore, the paddle assembly includes a paddle, a pin insertion hole and an ejector pin hole, the pin insertion hole is opened at the top of the paddle, the top of the paddle is sleeved on the bottom of the needle through the pin insertion hole, and the top of the paddle is hot-melt connected to the bottom end of the needle handle.

[0012] Furthermore, the ejector pin hole is formed at the bottom of the paddle.

[0013] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of the needle handle assembly, the needle assembly and the pick assembly, a set of blood collection needle mechanisms with good use safety is provided for disposable blood collection operations, which can help the blood collection personnel to push the needle into the needle handle after drawing blood from the patient, so as to hide the needle, and reduce the risk of infection caused by accidental scratches caused by the exposed needle while avoiding secondary contact with the needle. The top of the needle assembly is protected by the needle handle assembly, and the bottom of the needle assembly is protected by the pick assembly. After use, the needle assembly is pushed into the inside of the needle handle assembly by the pick assembly, so that the needle assembly is completely hidden in the needle handle assembly, thereby solving the problem that after blood collection is completed, the needle of the blood collection needle is exposed to the outside and is easily confused for secondary use, and the risk of infection caused by the needle accidentally contacting others after blood collection.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, a disposable blood collection needle includes a needle handle assembly 1, a needle assembly 2 and a pick assembly 3, wherein the needle assembly 2 is inserted into the bottom of the needle handle assembly 1, and the pick assembly 3 is sleeved on the bottom end of the needle assembly 2; the needle handle assembly 1 includes a needle handle 101, a needle groove 102, a protruding block 103 and a recess 104.

[0022] The notch 104 is formed at the bottom of the needle handle 101 , a needle groove 102 is formed at the top of the notch 104 , and raised blocks 103 are formed at both sides of the bottom of the needle groove 102 .

[0023] In which, the needle assembly 2 includes a needle 201 and an annular recess 202, and the annular recess 202 is provided in two groups, and the two groups of annular recesses 202 are respectively opened in the middle of the needle 201. The annular recess 202 is provided in two groups, and the two groups of annular recesses 202 are respectively opened in the middle of the needle 201, and the top end of the needle 201 is inserted in the needle groove 102.

[0024] Among them, the paddle assembly 3 includes a paddle 301, a pin hole 302 and a pin hole 303. The pin hole 302 is opened at the top of the paddle 301. The top of the paddle 301 is sleeved on the bottom of the needle 201 through the pin hole 302. The top of the paddle 301 is hot-melt connected to the bottom of the needle handle 101.

[0025] The ejector pin hole 303 is formed at the bottom of the paddle 301 .

[0026] It should be noted that the utility model is a disposable blood collection needle. During the production and processing of the blood collection needle, the upper part of the needle 201 is first inserted into the needle groove 102, and the annular notch 202 of the upper end of the needle 201 is locked with the protruding block 103, and then the needle insertion hole 302 of the pick 301 is inserted into the bottom of the needle 201, and the top of the pick 301 is hot-melt connected with the bottom of the needle handle 101, so that the top and bottom of the needle 201 are protected;

[0027] When using for blood collection, the user grasps the paddle 301 and rotates it to make the paddle 301 fall off the bottom of the needle handle 101, and then removes the paddle 301 from the bottom of the needle handle 101, and then grasps the needle handle 101 to draw blood from the patient's finger through the lower half of the needle 201. After the blood collection is completed, the user inserts the ejector hole 303 of the paddle 301 into the needle head of the needle 201 and pushes the needle 201 until the ejector hole 303 of the paddle 301 is inserted into the recess 104, so that the needle 201 is completely pushed into the needle handle 101, and the raised clamping block 103 clamps the annular recess 202 at the lower end of the needle 201 and the raised clamping block 103. At this time, the needle 201 cannot be taken out of the needle handle 101 at all, which can ensure that the entire blood collection needle can only be used once. At the same time, the risk of accidental puncture by the needle after blood collection is greatly reduced, thereby improving the safety of use.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
