Abstract
The utility model relates to a cardiovascular inserted syringe needle which is used for treating cardiovascular diseases and is matched with an inserted syringe. The cardiovascular inserted syringe needle comprises a puncture needle tube and a puncture needle tube seat which are connected together, wherein a sealing rubber sleeve is arranged at the tail of the puncture needle tube; a needle tube connecting seat A is sleeved at the rear end of the puncture needle tube seat; a needle connector is arranged in the center of the front end of the needle tube connecting seat A, and the needle tube connecting seat A is connected with a fine needle A through the needle connector; when the needle tube connecting seat A is sleeved on the puncture needle tube seat, the needle A penetrates through the rubber sleeve, and the rear end of the needle tube connecting seat A is sleeved on a needle seat port at the front end of a needle threading cylinder. According to the cardiovascular inserted syringe needle, lots of blood is prevented from flowing out of the puncture under the elastic sealing effect of the rubber sleeve, guide of a guide thread is convenient, and a puncture effect is improved.
Description
Technical field
This utility model relates to medical equipment technical field, is specifically related to a kind of supporting a kind of injection syringe for cardiovascular intervention syringe needle of insertion type syringe that is used for the treatment of cardiovascular disease.
Background technology
Cardiovascular disease mainly comprises the disease of the vascular systems such as heart, tremulous pulse, vein, blood capillary, its healthy of the threat mankind of can seriously endangering.When carrying out cardio-vascular interventional therapeutic, with puncture needle, directly thrust blood vessel or thrust blood vessel by ordinary syringe, and then syringe is unloaded from puncture needle, then seal wire is sent into blood vessel by piercing needle at present.The shortcoming of this piercing method is can flow out a lot of blood from needle holder mouth after puncture needle inserts blood vessel, wasted on the one hand valuable blood, also can pollute work surface on the other hand, but also can be in wearing the process of seal wire injured blood vessel, even cause piercing process failure.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of a kind of injection syringe for cardiovascular intervention syringe needle of bleeding in when puncture of preventing.
For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of injection syringe for cardiovascular intervention syringe needle, comprise the puncture needle tubing, the puncture needle base that link together, and described puncture needle tubing afterbody has seal rubber plug; Also have a needle tubing Connection Block A who is socketed in puncture needle base rear end, the front end centre of needle tubing Connection Block A has syringe needle connector and connects fine needle head A by this syringe needle connector; When needle tubing Connection Block A is socketed on puncture needle base, syringe needle A penetrates described plug, and the rear end of needle tubing Connection Block A is socketed on the needle stand mouth of a front end of threading a needle.
During use, in advance needle tubing Connection Block A and piercing needle are socketed and are connected on syringe, after puncture vessel success, blood can enter syringe along fine needle head, can react puncture effect when the effect of fine needle head is just to puncture.Then pull out syringe and needle tubing Connection Block, fine needle head also pulls out, and puncture conductor housing is bored a hole and entered puncture needle tubing also along puncture needle tubing intravasation along the plug of fine needle head puncture, so can be not hemorrhage.
This utility model is under the elastic force sealing function of plug, and blood can not flow out in a large number in puncture place, has facilitated seal wire guiding, has improved puncture effect.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional structure schematic diagram of this utility model;
In figure, needle tubing, 2. plug, 3. puncture needle base, 4. fine needle head A, 5. needle tubing Connection Block A, 6. needle stand mouth 1. puncture.
The specific embodiment
A syringe needle, comprises the puncture needle tubing 1, the puncture needle base 3 that link together, and described puncture needle tubing 1 afterbody has seal rubber plug 2; Also have a needle tubing Connection Block A who is socketed in puncture needle base 3 rear ends, the front end centre of 5 needle tubing Connection Block A5 has syringe needle connector and connects fine needle head A4 by this syringe needle connector; When needle tubing Connection Block A5 is socketed on puncture needle base 3, fine needle head A penetrates described plug, and the rear end of needle tubing Connection Block A is socketed on the needle stand mouth 6 of a front end of threading a needle.
