Abstract

The utility model discloses a double-cavity syringe, which comprises a cavity, a cannula and push rods arranged in the cavity. The cavity is separated into two independent cavities, the two cavities are sleeved in the cannula together, and one push rod is arranged in each cavity. Injection channels of the two cavities are converged at the tail part of a needle and provided with one injection needle. The two cavities of the syringe can accommodate two different liquors at the same time, and the two different liquors can be injected on a patient in turn by only one-time needling at the first time when the patient is rescued. The double-cavity syringe is mainly applied to an operation of quickly establishing an artificial respiration channel when a serious difficult breathing emergency patient is rescued, and can finish two functions of air exhaust and medicament administration in shortest time to facilitate the rescue of a seriously sick person. The double-cavity syringe has the advantages of simple structure, quick and convenient operation and safe and reliable use, and can realize medicament administration at the first time when the seriously sick person is rescued and win precious rescue time.

Description

Dual chamber syringe

Technical field

This utility model relates to medical instruments field, the dual chamber syringe of using during particularly a kind of critically ill patient rescues.

Background technology

The ordinary syringe of using can only be finished a shot or the individual event function of bleeding at present.Inject two kinds of medicines successively as need, then need injection at twice, the patient suffering is bigger.Can not set up the critically ill patient of respiration channel and the critically ill patient of cardio-pulmonary resuscitation with the method for intubate again for dyspnea, will implement the percutaneous puncture trachea usually and expand and to cut the art puncture and intubation and set up respiration channel.In this operation, at first to puncture, during puncture needle point whether reach the trachea domestic demand by the behaviour person of being on hand fall through the sense and bleeding of syringe judge.

The utility model content

Technical problem to be solved in the utility model just provides a kind ofly puts pipe as trachea rescuing the dyspnea critical patient, set up in the operation of artificial respiration's passage, can in the very first time, realize bleeding and two functions of administration, integrate a kind of dual chamber syringe of two kinds of functions, make swift to operate easyly, rescue being critically ill and Yan Gengneng wins and protects expensive rescue time.

Technical problem of the present utility model adopts following technical proposals to solve:

A kind of dual chamber syringe comprises cavity, sleeve pipe and is contained in push rod in the cavity that it is characterized in that described cavity is divided into two individual cavity, two cavitys together are sleeved in the sleeve pipe, adorn a push rod in each cavity.

The injection canal of described two cavitys converges when arriving Aculeata and is one, establishes an injection needle altogether.

This utility model compared with prior art has following characteristics;

The utlity model has two cavitys, can hold two kinds of different medicinal liquids simultaneously, can be when giving emergency treatment to a patient in the very first time as long as an acupuncture can be given two kinds of different medicinal liquids of patient injection in order.Be mainly used in serious symptom dyspnea first-aid patients and set up fast when rescuing in the operation of artificial respiration's passage, can finish in the shortest time and bleed and two functions of administration, this rescue ten for the critical patient is useful.Simple in structure, swift to operate easy, safe and reliable.When being critically ill rescue, can realize very first time administration, win and protect expensive rescue time.

Description of drawings

Fig. 1 is this utility model structural representation,

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further elaborated:

This utility model is a kind of dual chamber syringe, and cavity is divided into 4,5, two cavitys of two individual cavity and together is sleeved in the sleeve pipe 3, adorns a push rod 2 in the cavity 4, adorns a push rod 1 in the cavity 5.The injection canal of two cavitys converges when arriving Aculeata and is one, connects an injection needle altogether.

Concrete operations are:

By the therapeutic scheme that pre-establishes, two kinds of medicines of the required use of suction in the cavity of the left and right sides have earlier been injected first kind of medicine, and then have been promoted another push rod, and second kind of medicine injected when 1, injecting, and end of operation is extracted syringe.

2, as there not being taboo, also can promote two push rods simultaneously, inject two kinds of medicines simultaneously.

3, if use when first aid, this syringe is installed on the tracheal dilating forceps, is clamped by the pin of tracheal dilating forceps folder and pincers point, fills with the medicine of the necessary usefulness of institute when rescuing at first for chamber, a syringe left side, and as medicines such as epinephrines, right chamber then is a small amount of normal saline.Thrust trachea with stretching pliers pincers point during operation, bleed with right chamber push rod earlier, realization is to the judgement of depth of needling, when confirming that puncture needle enters the trachea correct position, at once advance left chamber push rod, the very first time is given in the patient's trachea and gives first aid medicine, together takes out with puncture needle after finishing this function, carries out next step operation.

Claims

1. dual chamber syringe comprises cavity, sleeve pipe and is contained in push rod in the cavity that it is characterized in that described cavity is divided into two individual cavity (4,5), two cavitys (4,5) together are sleeved in the sleeve pipe (3), adorn a push rod in each cavity.

2. dual chamber syringe according to claim 1, the injection canal that it is characterized in that described two cavitys converge when arriving Aculeata and are one, connect an injection needle altogether.
