Abstract
The utility model discloses a kind of Medical pressurizer vent valves, including air escape valve seat and air valve, air escape valve seat front end is provided with the first card convex, air escape valve seat rear end is provided with the second card convex, air escape valve seat middle position is provided with connecting hole, and air valve includes the valve port while of the valve seat of bottom, the valve body above valve seat and valve body side, and valve body is equipped with sealing cover far from valve port while side, connection external screw thread is provided on valve seat, valve seat is fixedly mounted in connecting hole.Solving existing pressurizer does not have vent valve that the easy feed liquor failure of sensor or silicone tube residual air is caused to enter in body cavity the technical issues of influencing operation.
Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of Medical pressurizer vent valves.
Background technique
Infusion is a kind of common therapeutic modality of adjuvant treatment, is carried out in operation or therapeutic process to patient at present defeated
Liquid is to reach better therapeutic effect.Hospitals at Present generallys use pressurizer and pressurizes infusion to accelerate transfusion speed.Mesh
Preceding existing pressurizer does not install vent valve additional mostly, and silicone tube is directly attached with the quick coupling of pressurizer.Normally make
With a Duan Shuizhu is needed in silicone tube when pressurizer, this makes in the use process of pressurizer, and there are a difficult points: existing
Just when starting pressurizer, the water column in silicone tube enters in body cavity from uteroventral operation device or other instruments, discharges water column
Due to foring certain air pressure there are air in rear silicone tube, cause the liquid in pressurizer that can not flow into silicone tube,
Therefore silicone tube and quick coupling junction must be slightly turned, this portion gas is discharged after starting pressurizer.
However dynamics is difficult to control using manually exhaust mode, the liquid that may cause in pressurizer largely flows into silica gel
In pipe even quick coupling, due to there are sensor, being easy that sensor feed liquor is allowed to fail at quick coupling；And the side of manual exhaust
Formula is easy to cause air discharge to be not thorough, and the air formation moisture film bubble of silicone tube remaining enters doctor in pressurizer use process
In treatment instrument, body cavity, release in the cavity causes the vibration of endoscope visual field, to influence the progress of operation.
Utility model content
There is no vent valve that the easy feed liquor failure of sensor or silicone tube residual air is caused to enter people to solve existing pressurizer
The technical issues of operation is influenced in body cavity body, the utility model devises a kind of Medical pressurizer vent valve.
The utility model adopts the following technical solution:
A kind of Medical pressurizer vent valve, including air escape valve seat and air valve, the air escape valve seat front end are provided with first
Card convex, the air escape valve seat rear end are provided with the second card convex, and the air escape valve seat middle position is provided with connecting hole, the air valve packet
The valve port while of the valve seat of bottom, the valve body above valve seat and valve body side is included, the valve body is equipped with close far from valve port while side
It covers, is provided with connection external screw thread on the valve seat, the valve seat is fixedly mounted in the connecting hole.
Preferably, being provided with pressure gauge on the valve body.
Preferably, the material of the air escape valve seat, air valve is brass or stainless steel.
Preferably, first card convex connects feed liquor silicone tube, second card convex connects out liquid silicone tube.
Preferably, the valve seat is to be threadedly coupled with the connection type of connecting hole.
The beneficial effects of the utility model are: 1, by the way that vent valve is arranged in the silicone tube below quick coupling, make
When with pressurizer, open deflation threshold switch by silicone tube water column and air from valve port while be discharged so that the liquid in pressurizer
Body can be flowed into steadily in silicone tube；If 2, occurring moisture film bubble in pressurizer use process to enter in silicone tube, gas is opened
Moisture film bubble is discharged threshold switch from valve port while, to eliminate influence of the bubble to operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the connection schematic diagram of the utility model.
In Fig. 1-2: 1, quick coupling, 2, feed liquor silicone tube, 3, air escape valve seat, the 30, first card convex, 31, connecting hole, 32,
Second card convex, 4, air valve, 40, valve port while, 41, valve body, 42, pressure gauge, 43, sealing cover, 44, valve seat, 5, go out liquid silicone tube.
Specific embodiment
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model work is further specifically retouched
It states:
Embodiment: as shown in attached drawing 1-2, a kind of Medical pressurizer vent valve, including air escape valve seat 3 and air valve 4, it is described
3 front end of air escape valve seat is provided with the first card convex 30, and 3 rear end of air escape valve seat is provided with the second card convex 32, the air escape valve seat 3
Middle position is provided with connecting hole 31, and first card convex 30 connects feed liquor silicone tube 2, and second card convex 32 connects out liquid silica gel
Pipe 5 is separately connected feed liquor silicone tube 2 and out liquid silicone tube 5 by the first card convex 30, the second card convex 32, and air escape valve seat 3 is affixed
In silicone tube.
The valve seat 44 of the air valve 4 including bottom, 41 side of valve body 41 and valve body of 44 top of valve seat valve port while 40, institute
It states valve body 41 and sealing cover 43 is installed far from 40 side of valve port while, connection external screw thread, the valve body are provided on the valve seat 44
Pressure gauge 42 is provided on 41, the valve seat 44, which is connected through a screw thread, to be fixedly mounted in the connecting hole 31, the vent valve
Seat 3, the material of air valve 4 are brass or stainless steel, by the fixation peace of air valve 4 in such a way that valve seat 44 is threadedly coupled with connecting hole 31
On air escape valve seat 3, when starting pressurizer, by open valve port while 40 by silicone tube water column and air from valve port while
40 discharges, so that the liquid in pressurizer smoothly passes quick coupling 1, vent valve enters in human body, the pressure gauge on valve body 41
42 to show the fluid pressure passed through, adjusts pressurizer in time when fluid pressure is excessive or too small to adjust fluid pressure.
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
