Abstract
The utility model discloses a kind of Combined medical formula negative pressure device, including threeway, be arranged on rotating three-way valve and being connected to the negative tube of threeway side pipe in the middle of threeway.Described negative tube is made up of passage and body, is provided with receiving fluid or the cavity of vacuum in body, and passage connects with body.Solve negative tube in prior art and the technical problem of negative pressure can not be set the most again, and be provided with on negative tube with other medical apparatus and instruments with the use of joint, so can make negative tube and other medical apparatus and instruments with the use of time have better seal performance, decrease the contaminated probability of negative pressure tube fluid.
Description
Technical field:
This utility model belongs to medical instruments field, relates to a kind of negative tube, a kind of includes the medical of negative tube
Combination type negative pressure device.
Background technology:
Negative tube is to utilize a kind of medical equipment of being operated of negative pressure extracting liquid in pipe, existing negative tube be all
When dispatching from the factory set fixing negative pressure, design complex, and do not have on negative tube pressure detecting indicate device, during use without
Method determines that negative pressure overpressure is the most normal；Present negative tube is used alone more, is not provided with coordinating with other medical apparatus and instruments
The joint used, and in use, sealing property is not fine.
Utility model content:
In consideration of it, for the defect overcoming above-mentioned prior art, this utility model provides a kind of Combined medical formula negative pressure
Device, and provide the negative tube of a kind of atmospheric pressure state, solving negative tube in prior art can not be arranged the most again
The technical problem of negative pressure, and be provided with on negative tube with other medical apparatus and instruments with the use of joint, so can make to bear
Pressure pipe and other medical apparatus and instruments with the use of time have better seal performance, decrease the contaminated probability of negative pressure tube fluid.
The technical solution of the utility model is as follows:
A kind of Combined medical formula negative pressure device, including threeway, is arranged on the rotation three-way valve in the middle of threeway and is connected to three
The negative tube of logical side pipe.
Described negative tube is made up of passage and body, is provided with receiving fluid or the cavity of vacuum, passage in body
Connect with body.
Described body is made up of tube wall and underseal, and underseal is rubber stopper.
Being provided with screw thread between described tube wall and underseal, underseal is connected by screw thread and tube wall are fixing.
Described negative tube passage is made up of the nipple being arranged on syringe.
Described negative tube is by nipple and threeway slitless connection.
It is provided with pressure-indication means on described negative tube.
Described nipple outer wall is provided with sealing screw thread, and nipple is connected with threeway by sealing screw thread.
A kind of negative tube, described negative tube is made up of passage and body, is provided with and accommodates fluid or vacuum in body
Cavity, passage connects with body, and the cavity in body is atmospheric pressure state.
Described body is formed in one or combined pipe, and passage is made up of nipple, and nipple is provided with lid.
To be connected with syringe, syringe needle and negative tube respectively with the threeway rotating three-way valve, rotate three-way valve and make threeway
Three paths close, then rotate three-way valve and make syringe connect with negative tube, use syringe evacuation negative pressure inner air tube, make
Form negative pressure in negative tube, then rotate the closing of three-way valve negative tube, then rotate three-way valve, make syringe closing, syringe needle and negative pressure
Pipe connects, then, under the effect of negative pressure, negative tube extracts liquid by syringe needle, fulfils assignment；Use complete, rotate three-way valve and make
Path blockade between negative tube and syringe needle, unloads negative tube from threeway.
The beneficial effects of the utility model are: Combined medical formula negative pressure device simple in construction of the present utility model, user
Just, safe and reliable, applied widely.
