Abstract
The utility model relates to a portable syringe for special injection which is housed by a shell and is composed of a needle cylinder, a syringe needle and a piston. The utility model is characterized in that the anterior part of the piston body is provided with an inclosed medicine storing cavity whose piston cover is controlled to open by a piston handle through a piston rod so as to achieve the communication between the medicine storing cavity and a water solution cavity in the needle cylinder. The utility model integrates a syringe, a medicine storing ampoule and a sealing bottle and can pump the affected part where negative pressure is formed after injection. The utility model which can simultaneously encapsulate different injections of special type has the characteristics of easy use, convenient carrying, good safety, suitable to be widely used for the site first aid of field and special patients, particularly suitable for the special type injection of the first aid of snake bite.
Description
The extraordinary injection syringe of portable type belongs to and a kind of medium is imported the intravital medical equipment of people.
Conventional injector mainly partly is made up of syringe and piston two, when meeting injection and need allocate, will carry out mixed preparing earlier outside device, and takes out injection in time behind the medicine, generally only suitable professional health care personnel use.Also, carry inconvenience, needing in those operations in the open air to be unfavorable for the in time extraordinary injection patient's of injection rescue and treatment because injection separates with syringe and deposits.
The purpose of this utility model: be to provide a kind of portable type easy to use extraordinary injection syringe.
This utility model is to realize above-mentioned purpose like this.Syringe partly is made up of syringe and piston two, and the liquid infusion agent is housed in the syringe.Piston is made up of piston body, piston rod and piston handle, and an airtight drug storage chamber is arranged in the front portion of piston body, and piston handle is by the unlatching of piston rod control drug storage chamber piston cap, realizes itself and being communicated with of the interior water preparation chamber of syringe.Syringe needle and syringe nipple to be being threaded, and be added with sealing member between the two.Syringe needle is equipped with sealing cap outward, on the excircle of syringe and piston body and piston body and piston handle sealing gasket is housed, and the inwall of sealing cap and sealing gasket and shell is adjacent to.During use, remove outer encapsulating material and regulating piston handle, the drug storage chamber piston cap is opened, implement injection again after finishing the mixing of two kinds of injections by piston rod.
This utility model integrates syringe, storage medicine ampoule and air-tight bottle, have and encapsulate different extraordinary injections and characteristics easy to use simultaneously, also can form negative pressure to affected part after the injection aspirates, be easy to carry, safe and reliable, can be widely used in open-air and special patient's field first aid, be particularly suited for the injection of snakebite first aid with extraordinary injection.
Accompanying drawing is a structural representation of the present utility model.
Syringe needle (2) is housed on the nipple of syringe (5), and its left side cover has sealing cap (1). On the excircle of syringe (5) front portion reflexed pad (3) is housed, a front portion is the water of storing liquid injection in the tube Agent chamber (4), medicine storage cavity (9) is equipped with on the right side, aqua chamber (4), and piston cap (6) and trapezoidal card (8) are equipped with in its position adjacent with aqua chamber (4), and piston cap (6) links to each other with piston handle (15) by piston rod (10). Excircle at syringe (5) and piston body (11) is equipped with sealing gasket I (12), on the excircle of piston body (11) and piston handle (15) sealing gasket II (14) is housed. Whole syringe is encapsulated in the housing that is made up of front casing (7) and rear casing (13), and the end of rear casing is equipped with sealing rubber plug (16).
Embodiment of the present utility model is, syringe (5), piston body (11) and drug storage chamber (9) are made with medical transparent nonmetallic materials, and syringe needle (2) and piston rod (10) are made with stainless steel material.Sealing cap (1), opisthotonos pad (3), piston cap (6), trapezoidal card (8), rubber stopper (16) are processed with medical grade rubber, sealing gasket I (12) and sealing gasket II (14) are that two semicircles are formed, adopt flexible good plastic processing, piston handle (15), front casing (7) and rear casing (13) adopt the big slightly plastic production of hardness.Press the medical disinfecting method to after the syringe sterilization, in water preparation chamber (4) with drug storage chamber (9) the different extraordinary injection of packing into, install syringe needle (2), package sealing cap (1) and opisthotonos pad (3), and outside syringe (5) and piston body (11) and piston body (11) and piston handle (15), load onto through disinfectant sealing gasket I (12) and sealing gasket II (14), then with the syringe overall package in sterile shell.
