Abstract
The utility model relates to an injector for thoracic cavity puncture, which is composed of pinheads, a glass needle tube 2 and a needle pin, wherein, the two pinheads which present a 90 DEG angle are arranged on the glass needle tube 2, when the pinheads are closed, the pinheads can connect the needle or the rubber tube. The injector is characterized in that the outlets of the two pinheads are provided with valve plates, a sucking opening valve plate is arranged on one pinhead, an injection opening valve plate is arranged on the other pinhead, and the valve plates are medical valve plates. The injector stops the phenomenon that air leaks into the thoracic cavity, can continuously draw out the hydrothorax in the sufferer thoracic cavity, is safe and is convenient for thoracic cavity puncture.
Description
Technical field:
This utility model relates to a kind of thoracentesis syringe, belongs to technical field of medical instruments.
Background technology
Generally adopt the apparatus of thoracentesis to have ordinary syringe to connect simple and easy thoracic-puncture needle or ordinary syringe connection long-tail three way type thoracic-puncture needle at present both at home and abroad.When adopting ordinary syringe to connect simple and easy thoracic-puncture needle to extract hydrothorax, the operation doctor need connect or pull up syringe to repeated multiple times under the assistant cooperates, and operation sequence is loaded down with trivial details, wastes time and energy, and causes serious consequence in the careless slightly thoracic cavity of also air may being bled.When adopting ordinary syringe to connect long-tail three way type thoracic-puncture needle, though the operation doctor can be without the assistant, but needing to pull three-way cock with hands operates, because three-way cock also very easily gets rusty or weares and teares and comes off, the pars papillaris of syringe is fractureed easily, the air thoracic cavity of bleeding occurs and cause serious consequence.
Summary of the invention
The purpose of this utility model is to provide a kind of thoracentesis syringe, and is safe in utilization, convenient, serially hydrothorax in the patient thoracic cavity is extracted out, stopped the phenomenon that air bleeds the thoracic cavity.
The technical solution of the utility model is achieved in that the thoracentesis syringe, is made up of syringe needle, glass needle tubing and pintle, and wherein the glass needle tubing is provided with two syringe needles that become 90 °, can connect pin or sebific duct on the syringe needle; It is characterized in that: the exit of two syringe needles is provided with valve block, and a syringe needle is provided with to suck opens valve block, and another syringe needle is provided with injection and opens valve block.Valve block is medical valve block.
Good effect of the present utility model is both to have stopped the bleed phenomenon in thoracic cavity of air to take place, serially hydrothorax in the patient thoracic cavity is extracted out again safe in utilization, make things convenient for the thoracentesis syringe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described: as shown in Figure 1, the thoracentesis syringe, be made up of syringe needle, glass needle tubing 2 and pintle 3, wherein glass needle tubing 2 is provided with two syringe needles 1 and 4 that become 90 °, can be connected pin or sebific duct on the syringe needle 1 and 4; It is characterized in that: the exit of two syringe needles 1,4 is provided with 5,6, one syringe needles 1 of valve block and is provided with suction unlatching valve block 5, and another syringe needle 4 is provided with injection and opens valve block 6.Valve block is medical valve block.
During use, will link to each other with thoracic-puncture needle on the syringe needle on the glass tubing 21, and connect sebific duct on another syringe needle 4 on the glass tubing 2 and put into measuring cup.When the operation doctor spurs the pintle 3 of syringe, the inner negative pressure that produces of syringe, the valve block 5 that is located at syringe needle 1 exit this moment is driven by negative pressure to be opened, intrathoracic liquid is inhaled in the glass tubing 2, when liquid has reached the maximum on the glass tubing, the operation doctor is as long as advance the pintle 3 of syringe again, and unlatching was advanced to the liquid in the glass tubing 2 in the measuring cup after the valve block 6 on another syringe needle 4 was subjected to negative pressure at this moment, and repetitive operation can power cut-off after reaching standard volume.
Claims (2)
1, thoracentesis syringe is made up of syringe needle, glass needle tubing (2) and pintle (3), and wherein glass needle tubing (2) is provided with two syringe needle (1) and (4) that become 90 °, can be connected pin or sebific duct on syringe needle (1) and (4); It is characterized in that: the exit of two syringe needles (1), (4) is provided with valve block (5), (6), and a syringe needle (1) is provided with to suck opens valve block (5), and another syringe needle (4) is provided with injection and opens valve block (6).
