Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a needle holder.
Background
The peripheral arterial catheter is a pipeline which is percutaneously punctured into an artery and is reserved in a lumen of a human body to be communicated with the outside, can be used for monitoring blood pressure, judging blood volume and collecting arterial blood samples, is a main tool for monitoring hemodynamics of critically ill patients, and can reduce pain and vascular injury brought to the patients by repeated puncture.
Be provided with the blood sampling window on the peripheral arterial catheter, collect patient's arterial blood sample clinically through the blood sampling window, nevertheless can supply the blood sampling window volume of puncture blood sampling less, in busy critical care unit, medical personnel have very big needle puncture risk, and then probably have the risk of infecting blood source disease. And because the arterial catheter generally stays for 3-5 days in the human body, after repeatedly puncturing the rubber stopper in the blood sampling window for many times in the period, the rubber stopper is easy to break, the blocking capability is lost, and the bleeding is caused. Based on this, a needle holder is proposed.
Disclosure of utility model
The utility model aims to provide a needle holder which aims to solve the problems that a puncture cold risk of medical staff is increased when a blood sampling window is punctured for multiple times, and a rubber plug of the blood sampling window is easy to damage.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
The utility model provides a needle holder, includes connector, pipe and tail needle, the connector includes pjncture needle and needle holder, needle holder is cylindric, and is provided with and runs through U-shaped opening, the pjncture needle sets up inside needle holder, the connector afterbody links to each other with the pipe, the tail needle that is used for the puncture vacuum heparin tube is connected to the other end of pipe.
Furthermore, the needle holding part is made of transparent medical plastic materials.
Further, the tail needle is provided with a protective cover which is convenient to hold.
Further, a rubber sleeve is sleeved on the tail needle.
Further, the catheter is provided with a single-hand clamp.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model adopts the connector to connect with the blood sampling window of the peripheral arterial catheter, the puncture needle pierces the rubber plug of the blood sampling window, the needle holding part arranged outside the puncture needle wraps the puncture part, the puncture needle can be isolated, the hand of medical staff is protected, the risk of needle puncture injury is reduced, meanwhile, the U-shaped opening arranged on the needle holding part can clamp the catheters at two ends of the blood sampling window, the utility model is fixed on the blood sampling window, the utility model is convenient for the subsequent medical staff to connect different vacuum blood sampling tubes through the tail needle for collecting arterial blood samples of patients for a plurality of times, the puncture times are reduced, and the rubber plug in the blood sampling window is prevented from losing the blocking capability due to a plurality of times of punctures, thereby causing blood seepage.
