Abstract
The utility model relates to a sleeve type automatic air inlet and outlet medicine dispensing needle. The sleeve type automatic air inlet and outlet medicine dispensing needle is a device which is introduced medium into the inner of the device by hypodermic injection, intravenous injection and muscle injection, in particular to a dispensing medicine needle. The sleeve type automatic air inlet and outlet medicine dispensing needle comprises a syringe joint with an air inlet and outlet channel and a puncturing needle with an air inlet and outlet pipe. The puncturing needle is mounted on the syringe joint. The upper end and the lower end of the air inlet and outlet pipe respectively communicates with the air inlet and outlet opening of a syringe needle and the air inlet and outlet channel. The outside of the puncturing needle is coated an outer sleeve needle tube whose upper part is provided with a liquid inlet and outlet opening. A sealed body is mounted between the outer sleeve needle tube and the syringe needle of the puncturing needle. The utility model has the helpful effects that the sleeve type automatic air inlet and outlet medicine dispensing needle can reduce particulate to pollute and easily dispense medicine in order to greatly convenience medical staff and diminish the labor intensity of the medical staff.
Description
Affiliated technical field
This utility model relates to a kind of mode with subcutaneous injection, intravenous injection or intramuscular injection medium is introduced intravital apparatus, especially dispensing needle.
Background technology
At present, known dispensing needle exists particle contamination, shortcoming such as the effort of making up a prescription.
Summary of the invention
In order to overcome the deficiency of existing dispensing needle, this utility model provides a kind of bushing type automatic air intake and discharge dispensing needle.
The technical scheme that its technical problem that solves this utility model adopts is: bushing type automatic air intake and discharge dispensing needle is by the syringe adapter of bringing the exhaust passage into, and the puncture needle of bringing exhaustor into that is fixed on the syringe adapter is formed.The upper end of air inlet-outlet pipe communicates with porting on the syringe needle, and the lower end communicates with intake and exhaust channel.The overcoat needle tubing is equipped with in the outside of puncture needle, and the top of overcoat needle tubing has the liquid in-out mouth, between overcoat needle tubing and the puncture needle syringe needle seal is housed.
The beneficial effects of the utility model are: owing to used following three technology: bushing type, and trachea is built-in, smooth in appearance; The front cutting with bottle stopper has been avoided in the side perforate of trocar tube outside; Sealing is not disturbed the gas-liquid twice mutually, fully gets rid of the positive/negative pressure in the bottle.So can reduce particle contamination, make make up a prescription free and relaxed.Thereby having made things convenient for the medical worker widely, alleviated their labor intensity, is the ideal utensil that makes up a prescription.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is that this utility model is lived front view.
Among the figure: 1, porting, 2, seal, 3, the liquid in-out mouth, 4, the overcoat needle tubing, 5, puncture needle, 6, air inlet-outlet pipe, 7, intake and exhaust channel, 8, syringe adapter.
The specific embodiment
In the embodiment shown in fig. 1, bushing type automatic air intake and discharge dispensing needle is by the syringe adapter 8 of bringing exhaust passage 7 into, and the puncture needle of bringing exhaustor 6 into 5 that is fixed on the syringe adapter 8 is formed.The upper end of air inlet-outlet pipe 6 communicates with porting 1 on the syringe needle, and the lower end communicates with intake and exhaust channel 7.Overcoat needle tubing 4 is equipped with in the outside of puncture needle 5, and the top of overcoat needle tubing 4 has liquid in-out mouth 3, between overcoat needle tubing 4 and puncture needle 5 syringe needles seal 2 is housed.
The smooth in appearance of overcoat needle tubing 4 is convenient to puncture; Liquid in-out mouth 3 is the side opening of overcoat needle tubing 4, has avoided the front cutting with bottle stopper; Seal 2 does not disturb gas, liquid twice mutually, can fully get rid of the positive/negative pressure in the medicine bottle.
