Abstract
The utility model belongs to a medical apparatus, which is characterized in that a gasbag type auxiliary booster outer casing is arranged on the periphery of a needle cylinder and a pintle, a gasbag auxiliary boosting cavity is arranged at the inner rear part of the gasbag type auxiliary booster outer casing, the front end of the auxiliary boosting cavity is contacted with the rear end of the pintle, a gas bag is arranged in the auxiliary boosting cavity, and the gas bag is connected with an air source through a connecting pipe. The structure of the utility model is simple and reasonable, the injection speed can be conveniently controlled by controlling the inlet velocity, the labor intensity of a medical care personnel can be greatly lighten, the utility model is applicable for the intravenous transfusion and the intravenous injection, etc. under different conditions, and the utility model provides a convenient and quick transfusion appliance for the foundation base rescue, the field rescue and the ambulance car rescue.
Description
This utility model belongs to medical apparatus and instruments, relates generally to the injection utensil.
At present, aspect clinical treatment and nursing, the syringe that relates to the venous transfusion injection mostly is the manual mode syringe, injects by pushing manually, and not only medical personnel's labor intensity is big, and manual pushing speed is irregular, advances medicine speed and is difficult to keep constant.
The purpose of this utility model provides a kind of employing Compressed Gas and does power and force to push, and pushing speed is even, can alleviate medical personnel's labor intensity greatly, and volume is little, the gasbag-type booster that cost is low.
In order to achieve the above object, this utility model provides a kind of gasbag-type booster, comprise syringe, pintle and syringe needle, it is characterized in that gasbag-type booster shell being set in the periphery of syringe and pintle, the rear portion is provided with air bag boosting chamber in the gasbag-type booster shell, the front end in air bag boosting chamber contacts with the rear end of pintle, and air bag boosting intracavity is provided with air bag, and air bag joins through connection tube and source of the gas.
Described connecting line is divided into two-way, and one the tunnel is air inlet pipe, and one the tunnel is exhaustor.
On the described air inlet pipe breather check valve is set.
On the described exhaustor vent valve is set.
This utility model is simple and reasonable for structure, the infusion model that traditional utilization pushes is manually changed into the infusion model of making power of air pressure, realized the mechanized operation of venous transfusion injection, make transfusion speed evenly adjustable, by regulating the air inflow and the intake velocity of air bag, can control transfusion speed and time easily, applicable to the venous transfusion under the different condition, intravenous injection etc., for basic unit's rescue, open-air rescue, ambulance rescue etc. provide convenience simple and direct infusion set.It has volume little, be easy to carry, characteristics such as applied range, low price.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this utility model and air pump connection diagram.
Among Fig. 1, this utility model comprises syringe needle 1, syringe 3, pintle 4, gasbag-type booster shell 5, air bag boosting chamber 6, air bag 7, air inlet pipe 10, exhaustor 9, breather check valve 8.The front end in air bag boosting chamber contacts with the rear end of pintle, when Compressed Gas after air inlet pipe, breather check valve enter air bag, air bag is swollen to rise, and promotes air bag boosting chamber and promote pintle through air bag boosting chamber to travel forward, and liquid medicine injection 3 is injected reposefully in patient's the body.
Among Fig. 2, the air bag 7 of gasbag-type booster is connected with the air outlet slit 13 of Compressed Gas pump 14 with air inlet pipe 10 by breather check valve 8, air outlet slit 13 places are provided with outgassing nonreturn valve 12, to prevent that air from refluxing, air intlet 17 places of Compressed Gas pump are provided with air filter 18, on the exhaustor 9 of gasbag-type booster air bag vent valve 11 are set.
When an injection operation begins, earlier syringe needle is inserted in patient's the body, open the Compressed Gas pump after seeing blood back, after Compressed Gas enters air bag, air bag is swollen to rise, and promotes air bag boosting chamber and promote pintle through air bag boosting chamber to travel forward, and liquid medicine injection is injected reposefully in patient's the body.
After an injection operation finishes, the Compressed Gas in the air bag can be discharged by opening vent valve, so that carry out next injection operation.
By the rotational speed regulation switch 15 that the Compressed Gas pump is set, the position of time-controllable device 16, can regulate the air inflow and the intake velocity of air bag, can control transfusion speed and time easily, reach control injection speed and the purpose of advancing dose.Remove the physical work that manually pushes away syringe, and can avoid into defectives such as dose is inhomogeneous.
The Compressed Gas pump can adopt peristaltic pump, also can adopt other forms of compressor pump (as piston pump, centrifugal pump etc.), also can cooperate with air relief valve, uses compressed gas cylinder to do source of the gas.
This utility model is simple and reasonable for structure, by the control intake velocity, can control injection speed easily, can alleviate medical personnel's labor intensity greatly, applicable to the venous transfusion under the different condition, intravenous injection etc., for basic unit's rescue, open-air rescue, ambulance rescue etc. provide convenience simple and direct infusion set.
