Description

Technical Field

[0001] The present application relates to the field of needle protection devices, and in particular, to an anti-puncture needle protection device. Background Art

[0002] Sharps injuries are accidental injuries caused by needles and other sharp objects to medical personnel during work. They are the most common occupational injuries in medical work. According to surveys, more than 20 pathogens have been confirmed to be transmitted through needlestick injuries, leading to occupational infections. Among them, the most common ones are hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Once injured by a sharp object contaminated by the patient's body fluids, the operator will face the risk of blood-borne infectious diseases such as hepatitis B, hepatitis C, and AIDS.

[0003] Nurses are responsible for blood drawing, injection, venipuncture and other work that involves close contact with sharps in hospitals, so they have become the group with the highest incidence of medical sharps injuries, accounting for 42% to 70% of the total number of medical sharps injuries. Sharps injuries occur in the following links: when drawing blood during the operation, being stabbed by improperly placed sharps after the operation, putting the needle cap back on both hands after the operation, and improperly separating the needle after the operation. In the busy work, nurses can easily get needles stuck in their hands by mistake, causing blood diseases.

[0004] In clinical practice, the existing infusion needle cap needs to be removed before infusion. After the infusion is completed, the needle is exposed and easily stabs medical staff or patients. Therefore, the needle is usually inserted directly into the infusion bottle after being removed. However, the needle contains blood, which will cause the infusion bottle to be contaminated and cannot be recycled. At the same time, this action itself is accompanied by the possibility of needlestick injuries. In order to solve the above problems, the present application provides an anti-stab needle protection device. Utility Model Content

[0005] In order to make up for the above shortcomings, the present application provides an anti-puncture needle protection device, which aims to improve the problem that the needle is exposed and can easily puncture medical staff or patients.

[0006] An embodiment of the present application provides an anti-puncture needle protection device, including a needle assembly, a protective sleeve is slidably sleeved on the needle assembly, a through hole is opened on the side wall of the protective sleeve, a limiting opening is opened on the side wall at one end of the through hole, the protective sleeve is clamped on the needle assembly through the through hole, and is arranged to wrap the needle assembly.

[0007] In a specific embodiment, the needle assembly includes a needle connecting pipe, one end of the needle connecting pipe is connected to the needle, and the other end of the needle connecting pipe is connected to a hose, and the protective sleeve is sleeved on the needle connecting pipe and the needle.

[0008] In a specific embodiment, a pinch block is fixedly connected to the outer wall of the needle connecting pipe, and the pinch block is located in the through-hole.

[0009] In a specific embodiment, a push block is fixedly connected to the outer wall of the protective sleeve.

[0010] In a specific embodiment, the protective sleeve is elastically configured.

[0011] In a specific embodiment, openings are provided on the side walls at both ends of the through-hole.

[0012] The beneficial effects of the present application are as follows: by arranging a protective sleeve on the needle assembly, after the needle is pulled out, the protective sleeve can be pushed onto the needle, so that the protective sleeve wraps the needle to avoid the needle being exposed to the outside and stabbing medical staff or patients. At the same time, a through hole is opened on the protective sleeve to facilitate the protective sleeve to be put on the needle assembly. In addition, a limiting hole is opened on the side wall of the through hole. The protective sleeve is rotated to move the pinch block into the limiting hole, thereby achieving the purpose of limiting the protective sleeve and preventing the protective sleeve from falling off the needle assembly.

[0019] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0020] See also Figure 1-4 The present application provides a device for protecting a needle 120 from puncture, comprising a needle assembly 10, a protective sleeve 20 being slidably sleeved on the needle assembly 10, a through hole 30 being provided on the side wall of the protective sleeve 20, and a limiting hole 40 being provided on the side wall at one end of the through hole 30, the protective sleeve 20 being clamped on the needle assembly 10 through the through hole 30, and being arranged to wrap the needle assembly 10, specifically, the protective sleeve 20 is sleeved on the needle assembly 10, and after the needle 120 is pulled out, the protective sleeve 20 can be pushed onto the needle 120, thereby playing a protective role and preventing the needle 120 from puncturing medical staff or patients.

[0021] See also Figure 4 The needle assembly 10 includes a needle tube 110, one end of the needle tube 110 is connected to the needle 120, and the other end is connected to the hose 130. The protective sleeve 20 is sleeved on the needle tube 110 and the needle 120. When set, the protective sleeve 20 can slide on the hose 130, thereby pushing the protective sleeve 20 and moving the protective sleeve 20 toward the needle 120, so that the protective sleeve 20 wraps the needle 120.

[0022] See also Figure 2 and 4 A pinch block 140 is fixedly connected to the outer wall of the needle pipe 110, and the pinch block 140 is located in the through-hole 30. In the specific setting, the pinch block 140 is installed on the side wall of the needle pipe 110 to control the needle 120. At the same time, after the needle 120 is pulled out, the protective sleeve 20 is pushed to move onto the needle 120, and then the protective sleeve 20 is rotated to make the limiting opening 40 move to the pinch block 140, so that the pinch block 140 can be used to achieve the purpose of limiting the protective sleeve 20.

[0023] See also Figure 3 A push block 210 is fixedly connected to the outer wall of the protective sleeve 20. It should be noted that the push block 210 is installed on the outer wall of the protective sleeve 20 to facilitate the movement of the protective sleeve 20.

[0024] See also Figure 3 The protective sleeve 20 is elastically arranged, and openings are arranged on the side walls at both ends of the through-hole 30. Specifically, the through-hole 30 is provided on the protective sleeve 20, so that the protective sleeve 30 is conveniently put on the needle assembly 10. The protective sleeve 20 is elastically arranged, so that it is convenient to pull the protective sleeve 20 from the through-hole 30 to both sides, so that the protective sleeve 20 is put on the needle assembly 10. After loosening, the through-hole 30 of the protective sleeve 20 is reset.

[0025] When the present anti-puncture needle 120 protection device is used: before using the needle 120, the protective sleeve 20 is first installed on the hose 130. Specifically, the protective sleeve 20 is pulled apart from the through-opening 30 of the protective sleeve 20 to both sides of the through-opening 30, so that the protective sleeve 20 can be sleeved on the hose 130. Then, the through-opening 30 of the protective sleeve 20 is loosened to restore the protective sleeve 20, so that the protective sleeve 20 can be sleeved on the hose 130. The protective sleeve 20 is rotated so that the through opening 30 is not set corresponding to the pinch block 140. After the needle 120 is pulled out, the protective sleeve 20 can be rotated so that the through opening 30 is set corresponding to the pinch block 140. Then the push block 210 can be pushed to slide the protective sleeve 20 onto the needle 120 to wrap the entire needle 120, and at the same time, the limit opening 40 is corresponding to the pinch block 140. Then the protective sleeve 20 is rotated to move the limit opening 40 to the pinch block 140.

[0026] It should be noted that the specific models and specifications of the needle tube 110, the needle 120 and the hose 130 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
