Description

Blood taking needle with protection function

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a blood taking needle with a protection function.

Background

The blood taking needle consists of a needle head and a needle rod, the needle head is arranged at the head of the needle rod, the needle rod is connected with a sheath in a sliding way, and when an operator holds the needle tube to press the blood taking needle head on the limb of a patient, the needle head protrudes and pierces the skin to cause a minimally invasive operation;

the split type blood taking needle is a disposable blood taking needle which is commonly used clinically, basically replaces the syringe blood taking mode used in the last century, is often matched with a disposable blood taking tube for use, and the split type blood taking needle has the structure that the needle collecting needle is connected to a needle seat at the tail end of a hose of the intravenous infusion needle, when in use, the needle collecting needle is required to be rotationally fixed at the front end of an outer cylinder of a needle holder, after hand-held intravenous puncture is successfully carried out on veins, a vacuum blood taking tube is inserted into a cavity at the rear end of the needle holder, a blade opening of the needle collecting needle penetrates through a blood blocking sleeve and penetrates into a vacuum tube rubber plug, blood is sucked into the blood taking tube under the action of negative pressure, multiple tube collection can be repeatedly realized as required, the blood taking is finished, the intravenous puncture needle is pulled out for local hemostasis, and the blood taking needle is taken off from the needle holder and the blood taking needle is discarded in a waste box together with the intravenous puncture needle.

The existing blood taking needle has the following problems in use:

after the nurse draws blood from the patient, the bare blood taking needle is easy to be punctured when being treated;

after a nurse draws blood from a patient, the nurse is easy to cause needle puncture when the nurse returns the exposed blood taking needle to the trocar cap;

the bare blood taking needle after blood drawing is easy to cause the risk of infectious disease after accidentally injuring other people;

therefore, it is necessary to invent a lancet having a protective function.

Disclosure of Invention

The present utility model is directed to a lancet with protection function, which solves the problems set forth in the above-mentioned background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a blood taking needle with safeguard function, includes needle cap and blood taking needle seat, and the one end fixed intercommunication of blood taking needle seat has the blood taking needle head, and the one end fixed intercommunication that blood taking needle was kept away from to the blood taking needle seat has the heparin tube, one side fixedly connected with flank of blood taking needle seat, the opening has been seted up to one side of needle cap, and the flank can slide in the opening of needle cap one side, and the opening is for running through the one side that sets up at the needle cap.

In a preferred embodiment of the present utility model, the length of the needle cap is equal to the sum of the lancet head and the lancet holder.

In a preferred embodiment of the present utility model, the cross-sectional diameter of the cap is larger than the cross-sectional diameters of the blood collection tube, the blood collection needle holder, and the blood collection needle.

In a preferred embodiment of the utility model, one end of the blood collection tube far away from the blood collection needle seat is fixedly communicated with a joint.

Advantageous effects

1) The opening is formed in one side of the needle cap, so that the blood taking needle head can be protected, and the condition that the bare blood taking needle is easy to puncture when the nurse processes the bare blood taking needle after drawing blood from a patient is avoided;

2) The needle cap can slide on the surfaces of the blood taking needle head, the blood taking needle seat and the blood taking tube, so that the condition that a nurse returns to the blood taking needle cap is avoided, and the occurrence of needle puncture is avoided;

3) The needle sleeve protects the whole blood taking needle head, avoids accidental injury to nurses or patients, reduces the occurrence of needlestick injury, and also reduces the spreading risk of blood infectious diseases.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
