Abstract
The utility model discloses an injection syringe which comprises a syringe needle, a cylinder, a sealed rubber plug, a push rod and a needle handle. The syringe needle is arranged at the front end of the cylinder, the push rod is located in the cylinder, the sealed rubber plug is arranged at the front end of the push rod, and the needle handle is arranged at the rear end of the push rod. Exhaust holes are respectively arranged on the sealed rubber plug and the needle handle. One-way valves are respectively arranged at the connection of the syringe needle and the cylinder and the exhaust holes of the sealed rubber plug. Preferably, the one-way valves are flapper-type one-way valves. The injection syringe provided by the utility model can be used for extracting pneumatosis in thorax or maintaining negative pressure of a negative pressure drainage device. According to the injection syringe provided by the utility model, the injection syringe does not need to be pulled out after extraction every time, and can extract continuously, thereby bringing great convenience to operation.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of syringe, relates in particular to a kind of syringe for thoracic drainage and thoracentesis.
Background technology
A large amount of aerothoraxs, pneumatosis is extracted in puncture out can alleviate it to the compressing of lung or trunk, breathes or circulatory disturbance to improve.Hydrothorax or pneumatosis patient for the spontaneous hydrothorax of part or pneumatosis patient and thoracic injury, operation cause usually need patient's row closed drainage of thoracic cavity operation.For reaching preferably the closed drainage effect and alleviating medical personnel's burden, need clinically thoracocentesis device and negative pressure drainage device are used in conjunction with.
For extracting intrathoracic pneumatosis, or keep the negative pressure of negative pressure drainage device, need clinically to use syringe to extract gas in thoracic cavity or depression drainage device.But, use the syringe of prior art, need syringe is extracted after bleeding at every turn, can not continuous air extraction, complex operation and need cooperation between medical personnel.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and providing a kind of does not need syringe from extracting, syringe that can continuous air extraction.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of syringe comprises syringe needle, syringe, seal rubber plug, push rod and needle handle, and described syringe needle is arranged at the front end of described syringe; Described push rod is positioned at described syringe, and the front end of described push rod is provided with seal rubber plug, and the rear end of described push rod is provided with needle handle; Described seal rubber plug and needle handle are respectively equipped with steam vent, are provided with respectively check valve at the steam vent place of the junction of described syringe needle and described syringe and described seal rubber plug.
Further, described check valve is the flapper-type check valve.
Further, the capacity of syringe is 50-100ml, is convenient to packing.
The beneficial effects of the utility model are: use syringe of the present utility model, do not need after bleeding syringe is extracted at every turn, can continuous air extraction, and be very easy to operation.
Description of drawings
Fig. 1 is the structural representation of syringe of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining this utility model, and be not used in restriction this utility model.
The structural representation of syringe of the present utility model comprises syringe needle 9, syringe 3, seal rubber plug 4, push rod 2 and needle handle 1 as shown in Figure 1.Syringe needle 9 is arranged at the front end of syringe 3.Push rod 2 is positioned at syringe 3, and the front end of push rod 2 is provided with seal rubber plug 4, and the rear end of push rod 2 is provided with needle handle 1.Seal rubber plug 4 and needle handle 1 are respectively equipped with steam vent 6,7, are provided with respectively check valve 5,8 in the junction of syringe needle 9 and syringe 3 and steam vent 6 places; Check valve 5,8 is preferably the flapper-type check valve.
When using syringe to bleed, lift backward needle handle 1, seal rubber plug 4 moves backward with push rod 2, syringe 3 internal pressures reduce, check valve 5 is opened, gas in thoracic cavity or drainage bottle enters syringe 3 through syringe needle 9, and when the pressure in the pressure in syringe 3 and thoracic cavity or drainage bottle reached balance, check valve 5 was closed; Press forward needle handle 1, syringe 3 internal pressures increase, and the check valve 8 at seal rubber plug 4 places is opened, and the gas in syringe 3 and then is discharged through the steam vent 7 at needle handle 1 place in steam vent 6 enters push rod 2.Can guarantee the one-way flow of gas by flap valve.So repeat aforesaid operations, the gas in thoracic cavity or drainage bottle constantly can be discharged.Adopt this syringe, do not need after bleeding syringe is extracted at every turn, thus can continuous air extraction, be very easy to operation.
As preferably, the range of capacity of syringe is 50-100ml, is convenient to packing.
The above is only preferred embodiment of the present utility model, is not to limit practical range of the present utility model; If do not break away from spirit and scope of the present utility model, this utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of this utility model claim.
