Abstract
Disclosed is a pressurizing injector for medical nursing. Transfusion and blood transfusion are indispensable procedures for medical curing and nursing, but when a transfusion bottle with liquid medicine completely injected is to be replaced by a new one, patients are suffered much more pain since liquid medicine in the new transfusion bottle can only be injected into vein by reinserting a needle into the vein. The pressurizing injector comprises an injector body, a liquid outlet (1) of the injector body is connected with a flexible tee joint (2), a one-way liquid outlet valve (3) is connected to one end of the flexible tee joint and connected with a liquid outlet tube, a one-way liquid inlet valve (5) is connected to the other end of the flexible tee joint and connected with a liquid inlet pipe (6), the injector body is connected with an assistance ring (13) and provided with a cavity (10), and a piston (11) is mounted in the cavity and is connected with a piston rod (12) in a threaded manner. The pressurizing injector is used for medical nursing.
Description
Technical field:
This utility model relates to a kind of pressure liquid injector for internal medicine nursing.
Background technology:
Transfusion, blood transfusion are medical treatments, nurse requisite program, but at the one bottle of liquid of being totally lost, when needing defeated next bottle, often needing can the liquid afferent veins, increase a lot of painful from new transposing medicine bottle like this to patient.Particularly old man and child's blood vessel are thinner, change each time different medicines, and be all different to the stimulation of blood vessel, also strengthened nursing staff's workload, operates pretty troublesome.
Summary of the invention:
The purpose of this utility model is to provide a kind of safety: easy and simple to handle, step is few; And can increase work efficiency, alleviate the pressure liquid injector that is used for internal medicine nursing of patient's misery.
Above-mentioned purpose realizes by following technical scheme:
A kind of pressure liquid injector for internal medicine nursing, its composition comprises: syringe, the liquid outlet of described syringe connects the software tee T, one end of described software tee T connects unidirectional liquid valve, described unidirectional liquid valve connects drain pipe, the other end of described software tee T connects unidirectional liquid feed valve, described unidirectional liquid feed valve connects feed tube, described syringe connects the power-assisted ring, described syringe has cavity, in described cavity, piston is housed, described piston is threaded connection piston rod.
Be connected by interference fit between described pressure liquid injector for internal medicine nursing, the liquid outlet of described syringe and described software tee T.
Described pressure liquid injector for internal medicine nursing, described drain pipe outlet has block, and described feed tube import has block.
Described pressure liquid injector for internal medicine nursing, described software tee T, described unidirectional liquid feed valve and described unidirectional liquid valve are installed in housing, and described housing has upper cover.
Beneficial effect:
1. this utility model has overcome in prior art transfusion and need to often change medicine bottle, easily pollutes, and the shortcoming of troublesome poeration utilizes two individual event valves to control flow directions, is mainly used in pressurized blood transfusion, transfusion, secondly can also be with rinsing in Rhizoma Atractylodis Macrocephalae; The extraction ascites pleural fluid; Peritoneal lavage, injection, drain; The operations such as decompression.
This utility model compared with prior art, simple in structure, connect closely, reduce opportunities for contamination; Avoid repeatable operation the problems such as obstruction to occur.This product has safety, effectiveness, practicality and property of many uses, and is convenient clinical.
3. this utility model is quick, and is laborsaving during joint, greatly improves blood transfusion, transfusion speed, increases work efficiency, and more important is the salvage success rate that improves patients with hemorrhagic shock.
4. the software tee T of this utility model employing can make the connection between connector tightr, enters without air and antibacterial, has avoided secondary pollution, and simple structure is made simply, is easy to promote.
5. the power-assisted ring that adopts of this utility model can make the nurse economize strength pushing away the medicine time, and life-time service power-assisted ring can make the nurse reduce to get the probability of occupation disease.
6. piston of the present utility model and piston rod adopt to be threaded and can make piston more fastening with being connected of piston rod, and no matter piston and piston rod which is first bad, all one of them parts of need replacing only, reduced cost.
