Abstract

The utility model relates to the field of medical instruments, in particular to a special puncture needle for the department of cardiology. The special puncture needle comprises a needle head, a sleeve support and a conduit, wherein a positioning plate is arranged inside the sleeve support; the needle head penetrates through the bottom end of the sleeve support and penetrates out of the positioning plate; a position clamping device is arranged in a position, exposed out of the sleeve support, of the tail end of the needle head; the rear end of the needle head is communicated with the conduit; a check valve is arranged in a position where the needle head is connected with the conduit; and a switch is arranged on the conduit. The special puncture needle for the department of cardiology is reasonable in structural design; the sleeve support is used for maintaining the puncturing angle and depth of the needle head; the attached check valve is used for limiting the path direction and preventing the air from entering; therefore, the pain of patients is relieved, and the work difficulty of medical staff is reduced.

Description

The special-purpose puncture needle of a kind of intracardiac section
Technical field
This utility model relates to medical instruments field, the special-purpose puncture needle of especially a kind of intracardiac section.
Background technology
In intracardiac section clinically, to the method that pericardial effusion patient's treatment adopts puncture to extract, when present employed puncture needle exhausts hydrops at every turn and takes off syringe, must clamp drainage tube with mosquito forceps more, enter heart to avoid gas through the puncture needle head.This operational approach extremely bothers, and wastes time and energy, and paracentesis depth is wayward during operation, and injury of myocardium has increased misery to the patient easily, has increased medical worker's work difficulty.
The utility model content
The purpose of this utility model is to provide a kind of intracardiac section special-purpose puncture needle in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: the special-purpose puncture needle of a kind of intracardiac section, comprise syringe needle, bush support and conduit, described bush support inside is provided with location-plate, described syringe needle passes the bush support bottom and passes location-plate, the position that the syringe needle end exposes bush support is provided with the screens device, syringe needle rear end connecting tube, the position that described syringe needle is connected with conduit is provided with check valve, and described conduit is provided with switch.
The beneficial effect that this utility model has is: this utility model reasonable in design, casing support is used for keeping angle and the degree of depth of syringe needle puncture, and the check valve of setting up restriction path direction avoids air to enter, alleviate patient's misery, reduced medical worker's work difficulty.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
As shown in Figure 1, this utility model comprises syringe needle 1, bush support 2 and conduit 5, described bush support 2 inside are provided with location-plate 3, described syringe needle 1 passes bush support 2 bottoms and passes location-plate 3, the position that syringe needle 1 end exposes bush support 2 is provided with screens device 4, syringe needle 1 rear end connecting tube 5, the position that described syringe needle 1 is connected with conduit 5 is provided with check valve 6, and described conduit 5 is provided with switch 7.During use, syringe needle 1 passes bush support 2 bottoms and passes location-plate 3, puncture into patient's heart after, limit syringe needles 1 paracentesis depth with screens device 4, open the switch 7 on the conduit 5.
