Abstract
The utility model relates to a cardiovascular intervention syringe needle preventing bleeding. The cardiovascular intervention syringe needle preventing bleeding is used for treating the cardiovascular disease and matched with an intervention type injection syringe. The cardiovascular intervention syringe needle comprises a puncture needle tube and a puncture needle tube base which are connected together. A seal rubber plug is arranged at the tail of the puncture needle tube. The cardiovascular intervention syringe needle is further provided with a needle tube connecting base A which is connected to the rear end of the puncture needle tube base in a sleeved mode, a syringe needle connecting opening is formed in the center of the front end of the needle tube connecting base A, and the needle tube connecting base A is connected with a thin syringe needle body A through the syringe needle connecting opening. When the needle tube connecting base A is connected to the puncture needle tube base in the sleeved mode, the syringe needle body A punctures the rubber plug, and the rear end of the needle tube connecting base A is connected to a needle base opening in the front end of the puncture needle tube in a sleeved mode. Under the elastic seal action of the rubber plug, blood can not outflow at the puncture position in a large-amount mode, a guide wire is convenient to guide, and the puncturing effect is improved.
Description
Technical field
This utility model relates to medical equipment technical field, is specifically related to a kind of supporting anti-hemorrhage 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 anti-hemorrhage 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: anti-hemorrhage 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.
Described plug structure is: the upper top diameter of plug is greater than puncture needle bore, and there is the circular hole of one end band closing membrane in the central authorities of plug, and the diameter of two ends up and down of circular hole is greater than the diameter in the middle of it, and circular hole aperture surface is arc transition; Affiliated closing membrane and plug are for being connected as a single entity, and material is identical.
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;
Fig. 2 is the longitudinal cutaway view Amplified image of plug structure in Fig. 1.
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, 7. circular hole, 8. closing membrane 1. puncture.
The specific embodiment
Anti-hemorrhage injection syringe for cardiovascular intervention 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.Described plug structure is: the upper top diameter of plug 2 is greater than puncture needle bore, and there is the circular hole 7 of one end band closing membrane 8 in the central authorities of plug, and the diameter of two ends up and down of circular hole 7 is greater than the diameter in the middle of it, and circular hole aperture surface is arc transition; Affiliated closing membrane 8 is with plug 2 for being connected as a single entity, and material is identical.
