Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a needle holder. Background Technology
[0002] A peripheral artery catheter is a tube that is inserted percutaneously into an artery and left inside the body's lumen to communicate with the outside world. It can be used to monitor blood pressure, determine blood volume, and collect arterial blood samples. It has become the main tool for hemodynamic monitoring in critically ill patients, and can reduce the pain and vascular damage caused by repeated punctures.
[0003] Peripheral arterial catheters (PACs) are equipped with blood collection windows for collecting arterial blood samples. However, the collection windows are relatively small, posing a significant risk of needlestick injury to healthcare workers in busy intensive care units, and potentially leading to bloodborne infections. Furthermore, since PACs typically remain in the body for 3-5 days, repeated punctures of the rubber stopper within the collection window during this period can damage the stopper, causing it to lose its barrier function and resulting in bleeding. Therefore, a needle holder is proposed. Utility Model Content
[0004] The present invention aims to provide a needle holder to solve the problem that repeated punctures of the blood collection window increase the risk of needlestick injuries to medical staff and easily lead to damage to the rubber stopper of the blood collection window.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A needle holder includes a connector, a catheter, and a tail needle. The connector includes a puncture needle and a needle holding part. The needle holding part is cylindrical and has a through U-shaped opening. The puncture needle is disposed inside the needle holding part. The tail of the connector is connected to the catheter, and the other end of the catheter is connected to the tail needle for puncturing a vacuum blood collection tube.
[0007] Furthermore, the needle-holding part is made of transparent medical plastic material.
[0008] Furthermore, a protective cover is provided on the outside of the tail needle for easy gripping.
[0009] Furthermore, a rubber sleeve is fitted onto the tail needle.
[0010] Furthermore, the catheter is equipped with a single-hand clamp.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention uses a connector to connect to the blood collection window of a peripheral arterial catheter. A puncture needle is inserted into the rubber stopper of the blood collection window. The needle-holding part, located outside the puncture needle, covers the puncture site, isolating the needle, protecting the hands of medical personnel, and reducing the risk of needlestick injury. Simultaneously, the through-hole U-shaped opening on the needle-holding part can hold the catheters at both ends of the blood collection window, fixing the invention to the blood collection window. This facilitates subsequent collection of arterial blood samples from patients by connecting different vacuum blood collection tubes via the tail needle, reducing the number of punctures and preventing the rubber stopper inside the blood collection window from losing its barrier function due to repeated punctures, thus preventing bleeding.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0019] like Figure 1-3 As shown, a needle holder includes a connector, a catheter, and a tail needle. The connector includes a puncture needle and a needle holding part. The needle holding part is made of transparent medical plastic, is cylindrical, and has a through U-shaped opening. The puncture needle is placed inside the needle holding part. The transparent material allows medical staff to easily observe the connection between the puncture needle and the blood collection window. The cylindrical needle holding part isolates the puncture needle, reducing the risk of needlestick injury for medical staff. The through U-shaped opening on the needle holding part can hold the catheters at both ends of the blood collection window, fixing the device to the blood collection window and avoiding multiple punctures. The head and tail are connected to the catheter, and the other end of the catheter is connected to the tail needle for puncturing the vacuum blood collection tube. The tail needle can be connected to different vacuum blood collection tubes to collect arterial blood samples from patients multiple times. The tail needle is equipped with a protective cover for easy gripping, making it convenient for medical staff to hold and puncture the vacuum blood collection tube. The tail needle is also covered with a rubber sleeve, which can temporarily block the needle tip to prevent continuous bleeding during tube replacement. The catheter is equipped with a one-handed clamp, which allows medical staff to easily clamp the catheter with one hand, making it convenient for medical staff to open or close the catheter as needed.
[0020] The specific implementation process is as follows:
[0021] When collecting arterial blood samples from patients through the blood collection window of a peripheral artery catheter in the intensive care unit, the connector of this utility model is connected to the blood collection window. Specifically, medical staff hold the needle holding part with their index finger and thumb. The needle holding part is equipped with a puncture needle. The puncture needle is inserted into the rubber stopper of the blood collection window through the needle holding part. At the same time, the through-hole U-shaped opening on the needle holding part is fixed to the catheter on both sides of the blood collection window. The single-hand clamp is opened, the protective cover of the tail needle is held, and the vacuum blood collection tube is connected to the tail needle. Since the vacuum blood collection tube is evacuated in advance, the patient's blood sample is drawn into the vacuum tube under negative pressure to complete the blood collection operation. The tail needle can puncture different vacuum blood collection tubes multiple times to complete multiple blood collection operations. After the blood collection is completed, the catheter can be temporarily closed by closing the single-hand clamp to prevent infection.
[0022] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
