Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood drawing protection device. Background Art

[0002] Blood drawing generally refers to venous blood drawing, which is a common clinical examination method and is also called a blood test. The doctor needs to take the patient's venous blood as a specimen, and then analyze the patient's blood through chemical analysis to see if there is inflammation or viral infection in the blood, so as to find the cause of the disease.

[0003] Needlestick injuries refer to skin injuries caused by medical sharps such as injection needles, suture needles, and puncture needles. They are the most common occupational injuries among medical staff and one of the most dangerous transmission routes for blood-borne infectious diseases. The main cause of needlestick injuries is the lack of safe and effective safety devices during the needle cap removal and needle disposal process in clinical blood drawing, which leads to the problem of stabbing people. Utility Model Content

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A blood drawing protection device includes a blood drawing needle, one end of which is provided with a protection component.

[0006] The protective component includes a sleeve, and an installation groove is provided on the inner wall of the upper end of the sleeve, a rubber ring is fixedly installed in the inner cavity of the installation groove, a sliding groove is provided on the inner wall of the lower end of the sleeve, and a sliding tube is slidably connected to the inner cavity of the sliding groove, and a spring is fixedly connected between the port of the sliding tube and the inner cavity of the sliding groove.

[0007] Preferably, the blood drawing needle comprises a blood drawing tube, one end of which is provided with a needle.

[0008] Preferably, the rubber ring is fixedly sleeved on the port of the needle.

[0009] Preferably, the inner diameters of the sliding tube and the sleeve are the same.

[0010] Preferably, the lower end of the sliding tube extends to the outside of the bottom of the sleeve.

[0011] Preferably, the bottom of the sliding tube is higher than the bottom of the needle.

[0012] The utility model provides a blood drawing protection device. Compared with the existing technology, it has the following advantages:

[0013] The blood drawing protection device drives the sliding tube to slide in the sliding groove provided in the sleeve under the elastic force of the spring, so that the sliding tube is longer than the bottom of the needle, and the needle is located in the inner cavity of the sleeve and the sliding tube, so that the needle will not leak out, and thus will not cause puncture injuries to medical staff when taking the blood drawing needle.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 and 5 The utility model provides a technical solution: a blood drawing protection device, comprising a blood drawing needle 1, one end of which is provided with a protection component 2, the blood drawing needle 1 comprises a blood drawing blood tube 11, one end of which is provided with a needle head 12.

[0022] See also Figure 2-4 The protective component 2 includes a sleeve 21, and a mounting groove 24 is opened on the inner wall of the upper end of the sleeve 21. A rubber ring 23 is fixedly installed in the inner cavity of the mounting groove 24, and the rubber ring 23 is fixedly sleeved on the port of the needle 12.

[0023] A sliding groove 26 is provided on the inner wall of the lower end of the sleeve 21, and a sliding tube 22 is slidably connected to the inner cavity of the sliding groove 26. The inner cavity diameters of the sliding tube 22 and the sleeve 21 are the same, and a spring 25 is fixedly connected between the end of the sliding tube 22 and the inner cavity of the sliding groove 26. The lower end of the sliding tube 22 extends to the outside of the bottom of the sleeve 21, and the bottom of the sliding tube 22 is higher than the bottom of the needle 12. By the sliding tube 22 being higher than the bottom of the needle 12, the needle 12 will be wrapped in the sliding tube 22, so that it will not cause puncture to medical staff when taking the blood drawing needle.

[0024] When in use, the sliding tube 22 will be driven by the elastic force of the spring 25 to slide in the sliding groove 26 opened in the sleeve 21, so that the sliding tube 22 is longer than the bottom of the needle 12, so that the needle 12 is located in the inner cavity of the sleeve 21 and the sliding tube 22, so that the needle 12 will not leak out. Therefore, when taking the blood drawing needle, it will not cause stab injuries to medical staff. When the blood drawing needle is in use, the sliding tube 22 is directly pressed against the port of the blood bottle, and the sliding tube 22 and the spring 25 are retracted into the sleeve 21 in the inner cavity of the sliding groove 26 by squeezing, so that the needle 12 will leak out, and the needle 12 can be directly inserted into the blood bottle. After the blood drawing is completed, the needle 12 is pulled out, and the sliding tube 22 is automatically reset under the elastic force of the spring 25, and the needle 12 is wrapped again.
