When carrying out the drainage operation through the negative pressure ball, the drainage is emptyd to each port of accessible three way switch adjustment three way connection with opening, need empty the drainage, before carrying out the operation of negative pressure ball chock plug extraction, carry out the pressure release of exhausting through the exhaust port earlier for realize pressure balance in the runner, rethread drainage liquid pipe is emptyd the drainage to liquid, avoided frequently opening negative pressure ball sealing chock plug, the liquid splash in the runner has also been avoided simultaneously, for medical personnel provide effectual protection.
Description
Technical Field
The utility model relates to a negative pressure ball drainage device with a splash-proof switch in the field of medical appliances.
Background
In clinic, drainage operation is often required for patients to drain intraoral hematocele, estimate bleeding volume, exhaust and drain, prevent infection, promote wound healing and the like. At present, a negative pressure ball is generally adopted for wound drainage and is respectively connected with a wound drainage tube and an inclined drainage tube, and drainage is carried out through negative pressure generated by the negative pressure ball, but when negative pressure ball drainage is carried out, because negative pressure is kept in a flow channel comprising the negative pressure ball, when drainage is carried out, especially when a negative pressure ball plug is pulled out, liquid in the flow channel is easy to splash, and the operation is not beneficial to occupational protection of medical staff.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art, providing a negative pressure ball drainage device with a splash switch, which can balance the internal and external pressure of a flow passage when in drainage operation.
One technical scheme for achieving the above purpose is as follows: a negative pressure ball drainage device with a splash-proof switch comprises a negative pressure ball, and is characterized by also comprising a three-way joint and a drainage liquid conduit joint,
the bottom of the negative pressure ball is provided with a three-way connector, the first end of the three-way connector is connected with the negative pressure ball through the three-way connector, the three-way connector is provided with a three-way switch, and the three-way switch can seal any one port of the three-way connector and enable the rest two ports to be communicated;
the second end of the three-way joint is connected with the drainage liquid conduit joint, the third end of the three-way joint is an exhaust port end, and an exhaust port switch is arranged at the exhaust port end.
Furthermore, the top of negative pressure ball is equipped with the negative pressure drainage mouth, be equipped with the one-way valve that switches on the negative pressure drainage mouth.
Further, the exhaust port switch is a swing-open switch.
Furthermore, the drainage liquid catheter joint is connected with the needle cylinder.
The utility model discloses a negative pressure ball drainage device with splashproof switch has installed the three way connection who takes three way switch promptly additional at the port of negative pressure ball, and three way connection and drainage liquid pipe articulate, and three way connection's third end is the exhaust port end simultaneously exhaust port end department is equipped with the gas vent switch. When carrying out the drainage operation through the negative pressure ball, the drainage is emptyd to each port of accessible three way switch adjustment three way connection with opening, need empty the drainage, before carrying out the operation of negative pressure ball chock plug extraction, carry out the pressure release of exhausting through the exhaust port earlier for realize pressure balance in the runner, rethread drainage liquid pipe is emptyd the drainage to liquid, avoided frequently opening negative pressure ball sealing chock plug, the liquid splash in the runner has also been avoided simultaneously, for medical personnel provide effectual protection.
Drawings
Fig. 1 is a schematic structural view of the negative pressure ball drainage device with the splash switch of the present invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments with reference to the accompanying drawings:
referring to fig. 1, the negative pressure ball drainage device with splash proof switch of the present invention includes a negative pressure ball 1, a three-way joint 2 and a drainage liquid conduit joint 3.
The top of the negative pressure ball 1 is provided with a negative pressure drainage port 11, the negative pressure drainage port 11 is provided with a one-way conduction valve, and the bottom of the negative pressure ball 1 is provided with a three-way connector 12. The negative pressure ball 1 is used for providing negative pressure for the whole flow passage, the negative pressure drainage port 11 is connected with the wound surface through other medical appliance devices, and the three-way connector 12 is a leading-out port for liquid in the negative pressure ball 1.
Tee joint 2's first end is passed through tee joint 12 and is connected with the tee joint 12 of negative pressure ball 1, and tee joint 2's second end is connected with drainage liquid pipe connection 3, and tee joint 2's third end is the exhaust port end, is equipped with gas vent switch 21 at gas vent end department, and gas vent switch 21 adopts the formula switch of unscrewing, unscrews the exhaust, and the closure of screwing, rotatory cap need not to take off, has guaranteed the convenience of operation and the isolation effect of device. The three-way joint 2 is provided with a three-way switch 22, and the three-way switch 22 can close any one port of the three-way joint 2 and make the remaining two ports conducted.
When drainage operation is carried out, the negative pressure drainage port 11 is connected with the wound surface, and negative pressure drainage operation is carried out through the negative pressure ball 1.
Before the drainage needs to be poured and the plug head of the negative pressure ball is pulled out, the three-way switch 22 is rotated to conduct the exhaust port and the negative pressure ball 1, then the exhaust port switch 21 is opened, and the exhaust and pressure relief are carried out through the exhaust port, so that the pressure balance is realized in the flow channel. And then the drainage liquid catheter joint 3 is connected with the needle cylinder, the three-way switch 22 is rotated to conduct the drainage liquid catheter joint 3 and the negative pressure ball 1, liquid in the flow channel is sucked, drained and poured through the needle cylinder, the liquid is directly metered, meanwhile, frequent opening of the negative pressure ball sealing plug head is avoided, meanwhile, liquid splashing in the flow channel is also avoided, and effective protection is provided for medical personnel.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
