Description

Technical Field

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

[0002] Blood collection is a very important and common task in clinical work. At present, the blood collection needles commonly used in clinical practice mainly include straight blood collection needles and butterfly-wing blood collection needles. However, both of these blood collection needles have some obvious disadvantages.

[0003] The blood collection needles currently on the market have the following defects:

[0004] 1. To facilitate packaging and transportation, the lancet is packaged in a coiled shape. After opening the package, the entire lancet remains coiled. After a successful puncture, the operator needs to loosen the needle handle to draw blood from the other end. At this time, the needle handle is in a suspended state. Since it is not fixed, the needle may be separated from the blood vessel if not fixed carefully, requiring another puncture. This not only increases the patient's pain but also easily leads to disputes.

[0005] 2. After the blood collection needle is removed, the needle tip is exposed, which is very likely to cause needle stick injuries. Therefore, a fixable safety blood collection needle is proposed to solve the above problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a fixable safety blood collection needle to overcome the deficiencies in the prior art.

[0007] The technical solution of the utility model to solve the above technical problems is as follows: a fixable safety blood collection needle, including a lumen, characterized in that a needle is fixedly installed on the right side of the lumen, a handle No. 1 is fixedly installed on the front of the needle, the handle No. 1 is located at an end close to the left side of the needle, and a skin adsorption component is provided on the outside of the handle No. 1.

[0008] The skin adsorption component includes a connecting tube fixedly installed inside the No. 1 handle, a rubber ball fixedly installed on the top of the connecting tube, a suction cup fixedly installed on the bottom of the connecting tube, and the rubber ball and the suction cup are connected through the connecting tube.

[0009] The beneficial effects of the utility model are as follows: the needle is inserted into the patient's blood vessel through the No. 1 handle, then the rubber ball is squeezed to expel the air through the connecting tube and the suction cup, and then the suction cup is attached to the patient's skin near the blood drawing area. After the rubber ball is released, the suction cup absorbs the skin to fix the needle. Before removing the needle, the skin under the suction cup is gently pulled apart to allow air to enter. After the adsorption state is released, the needle can be removed. The whole process is simple and quick, which effectively improves the convenience and safety of the blood drawing operation.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, a protective tube is slidably installed on the outside of the lumen and the needle and is sleeved on the outside of the No. 1 handle. A sliding groove is opened on the surface of the protective tube, and the No. 1 handle is slidably installed inside the sliding groove.

[0012] Furthermore, a No. 2 handle is fixedly mounted on the back of the protection tube, and the No. 2 handle is located at an end close to the left side of the protection tube.

[0013] Furthermore, the top and bottom of the No. 1 handle are both provided with crescent grooves close to the back thereof, and the outer wall of the protective tube is slidably mounted inside the two crescent grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] Example 1, as Figures 1 to 3 As shown, a fixable safety blood collection needle includes a lumen 1, a needle 2 is fixedly installed on the right side of the lumen 1, a handle No. 1 is fixedly installed on the front of the needle 2, and the handle No. 1 is located at the end close to the left side of the needle 2. A skin adsorption component is provided on the outside of the handle No. 1.

[0022] The skin adsorption component includes a connecting tube 4 fixedly installed inside the No. 1 handle 3, a rubber ball 5 fixedly installed on the top of the connecting tube 4, and a suction cup 6 fixedly installed on the bottom of the connecting tube 4. The rubber ball 5 and the suction cup 6 are connected through the connecting tube 4.

[0023] When in use, first connect the lumen 1 to the negative pressure bottle, pinch the No. 1 handle 3 to insert the needle 2 into the patient's blood vessel, then squeeze the rubber ball 5 to expel the air inside it through the connecting tube 4 and the suction cup 6. After the air is expelled, bring the suction cup 6 into contact with the patient's skin near the blood drawing area. After the rubber ball 5 is released, the suction cup 6 can be adsorbed on the skin to fix the needle 2. At this time, the blood will flow into the negative pressure bottle through the needle 2 and the lumen 1. Before removing the needle, gently pull the skin under the suction cup 6 to allow air to enter. When the adsorption state is canceled, the needle 2 can be pulled out.

[0024] Example 2, as Figures 1 to 3 As shown, this embodiment is a further improvement based on Example 1, and its details are as follows:

[0025] A protective tube 7 is slidably installed outside the lumen 1 and the needle 2 and is sleeved on the outside of the No. 1 handle 3. A sliding groove 8 is opened on the surface of the protective tube 7, and the No. 1 handle 3 is slidably installed inside the sliding groove 8.

[0026] Through the provided sliding groove 8, the protective tube 7 can be slid on the outside of the No. 1 handle 3 and the needle 2. When the protective tube 7 moves to the left, the needle 2 can leak out and blood can be drawn. After the needle is removed, the protective tube 7 moves to the right, the needle is located in the protective sleeve, and the blood collection needle is in a safe state to prevent needlestick injuries.

[0027] Example 3, as Figures 1 to 3 As shown, this embodiment is a further improvement based on embodiment 1-2, and its details are as follows:

[0028] A second handle 9 is fixedly mounted on the back of the protection tube 7 , and the second handle 9 is located at an end close to the left side of the protection tube 7 .

[0029] The second handle 9 installed by hand is convenient for controlling the protection tube 7 to move left and right.

[0030] Example 4, as Figures 3 and 4 As shown, this embodiment is a further improvement based on embodiment 1-2, and its details are as follows:

[0031] The top and bottom of the No. 1 handle 3 are both provided with crescent grooves 10 near the back thereof, and the outer wall of the protective tube 7 is slidably mounted inside the two crescent grooves 10 .

[0032] The two crescent grooves 10 can restrict the protection tube 7 from sliding outside the No. 1 handle 3 and the needle 2, thereby preventing the protection tube 7 from being separated from the outside of the needle 2.

[0033] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
