Description

Catheter hemostix

Technical Field

The utility model relates to the field of medical supplies, concretely relates to catheter hemostix.

Background

With the development of nursing technology in recent years, in order to solve the problem of infusion for a long time in a patient, a midline

The application of the catheter, the CVC, the PICC and the transfusion port is increased, the number of times of venous vessel puncture of the patient is reduced,

when a patient needs to take a blood sample for testing, however, a nurse often needs to perform peripheral venipuncture on the patient,

patients suffer from multiple needle punctures, particularly when peripheral blood sampling is difficult.

However, these catheters are used for blood sampling to reduce the pain of the patient during puncturing, but the current nursing tools are not perfect enough, are inconvenient to operate and even cause needle stick injuries. The prior operating method comprises the steps that a syringe removes a needle connecting catheter to draw a certain amount of blood according to requirements, then the syringe needle is connected, and then blood samples are subpackaged in a plurality of vacuum blood sampling tubes. And the blood sampling tube has enough negative pressure, and the nurse needs to control the core bar of the injector by hand strength to reserve a proper amount of samples, which is the important reason that the nursing staff does not tend to use the catheter to sample blood. Especially, when patients with difficult peripheral puncture or serious infectious diseases such as HIV are encountered, the risk of occupational exposure of nursing staff is increased and the consequences are serious, no matter peripheral blood collection or catheter blood collection.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims at providing a pipe hemostix to solve the problem that proposes among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme:

a catheter hemostix comprises a needle cylinder core rod, a piston, a blood transfusion hose and a screw cap, wherein the needle cylinder core rod is provided with a needle cylinder core rod, a piston and a screw cap

The front end is equipped with blood input port and blood delivery outlet, blood delivery outlet connects the blood transfusion hose, be equipped with the thumb on the blood transfusion hose and press from both sides, the blood transfusion hose other end is connected with the output needle head, the output needle head is wrapped around and is had the blood blocking cover, link to each other through the output needle file between output needle head and the blood transfusion hose.

As an optimized technical proposal of the utility model, the surface of the output needle seat is provided with a friction increasing device

A pattern of forces.

As an optimized technical proposal of the utility model, the blood input port is connected by a screw

The screw connection is provided with a screw cap which can be tightly connected.

As an optimized technical proposal of the utility model, the screw cap is provided with a handle.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model is applied to the patients with transfusion catheters, and the patients do not need to receive puncture and catheter during blood sampling and testing

The hemostix is connected with the end of the conduit, the thumb clamp is clamped firstly, the needle cylinder core bar is pulled to draw quantitative blood, and then the screw is screwed down

The cap is opened, the thumb clamp is opened, the output needle is connected with the vacuum blood sampling test tube, and the blood in the needle cylinder can automatically flow into the blood sampling test tube

Inside the tube.

2. The utility model can protect the blood transfusion hose, the output needle seat, the output needle head and the blood blocking sleeve

Easily accomplish multi-tube collection without direct contact with exposed needle head, and without causing puncture wound to medical care personnel

And (4) danger.

3. The utility model is simple in operation, convenient to use can alleviate psychological pressure when the patient for suffering from serious infectious disease of menstrual blood propagation takes a blood sample, improves work efficiency.
