Abstract
The utility model relates to a blood collection needle cylinder. The needle cylinder comprises a needle seat and a sleeve, wherein the needle seat is sleeved at the front end of the sleeve; a first inserting base is arranged on one side of the needle seat; and a venous puncture needle is inserted into the first inserting base. The blood collection needle cylinder has the advantages that the needle seat is sleeved at the front end of the sleeve, so that the needle seat is in tight fit with the sleeve and can be conveniently detached; a cavity is formed in the needle seat, and one end of the venous puncture needle is inserted into one side of the cavity, so that the blood collection needle cylinder can be detached, and processing cost is low; a first sealing ring is arranged on the outer side of the venous puncture needle, a second sealing ring is arranged on the outer side of a thorn plug needle, and a sealing coating layer is arranged at a position where the needle seat is sleeved with the sleeve, so that parts of the blood collection needle cylinder are tightly connected, sealing property is high, and environment is difficult to pollute; and the truncated cone-shaped first inserting base is arranged on one side and at the periphery of the needle seat, so that the venous puncture needle easily and accurately penetrates a vein when venous blood is collected by the blood collection needle cylinder.
Description
Technical field
This utility model relates to a kind of blood sampling syringe, relates in particular to a kind of blood sampling syringe of medical instruments field.
Background technology
At present, the human venous blood specimen that gathers adopts the vacuum blood collection blood sampling tube mostly, and the demand of blood sampling syringe is also increasing.And nowadays, the sleeve of vacuum test tube is that integral type is connected or non-removable being fixedly connected with the connected mode of needle stand, therefore hospital can not separate and the processing of classifying the puncture needle that is fixed on the needle holder, causes easily environmental pollution and processing cost too high.Adopt dismountable blood sampling syringe, the sealing of blood sampling syringe is even more important.
Summary of the invention
This utility model is intended to invent a kind of blood sampling syringe of detachable and good airproof performance.
A kind of blood sampling syringe, comprise needle stand and sleeve, needle stand is socketed on barrel forward end, described needle stand one side is provided with the first plug socket, be plugged with venipuncture needle on the first plug socket, the needle stand opposite side is provided with the second plug socket, grafting spinosity plug pin on the second plug socket, needle stand inside is provided with cavity, venipuncture needle one end is plugged in cavity one side, the venipuncture needle outside is provided with the first sealing ring and the first sealing ring is located between needle stand and the cavity, and thorn plug pin one end is plugged in the cavity opposite side, and the thorn plug pin outside is provided with the second sealing ring and the second sealing ring is located between needle stand and the cavity.
Preferably, described needle stand and sleeve socket place are provided with the gasket coating layer.
Preferably, described needle stand is cylinder.
Preferably, described the first plug socket is located at needle stand one side and is on the circumferential edge of needle stand.
Preferably, described the first plug socket is round table-like.
The beneficial effects of the utility model are:
1. needle stand is socketed on barrel forward end, make needle stand and sleeve close-fitting and can be for convenience detach, needle stand one side is provided with the first plug socket, be plugged with venipuncture needle on the first plug socket, the needle stand opposite side is provided with the second plug socket, grafting spinosity plug pin on the second plug socket, needle stand inside is provided with cavity, venipuncture needle one end is plugged in cavity one side, makes the blood sampling syringe detachable, and processing cost is lower;
2. the venipuncture needle outside is provided with the first sealing ring and the first sealing ring is located between needle stand and the cavity, the thorn plug pin outside is provided with the second sealing ring and the second sealing ring is located between needle stand and the cavity, needle stand and sleeve socket place are provided with the gasket coating layer, making between blood sampling syringe each parts contact more tight and sealing is better, being not easy to cause environmental pollution;
3. the first plug socket is located at needle stand one side and is on the circumferential edge of needle stand, and the first plug socket is round table-like, and when gathering venous blood, venipuncture is needled into easily, accurate at the blood sampling syringe.
