Abstract

The utility model discloses a kind of suck-back devices for DMT 620M, including inverted cone shell, upper part of the housing to offer venthole, and venthole is fixedly connected escape pipe.The tip of cone shell offers air inlet, and air inlet is fixedly connected air inlet pipe.Ball is provided in shell, and the path length of ball is greater than the path length of air inlet, the path length of ball is greater than the path length of venthole.When the utility model air inlet pipe connects oxygen, ball is blown afloat oxygen by oxygen stream to flow out from escape pipe.When air inlet pipe disconnects oxygen or has inverted draft to pass through, ball is due to gravity or inverted draft effect is by air inlet hole plug prevents inverted draft from passing through, to realize unidirectional air guide and anti-suck.And the utility model structure is simple, performance is stable, material is easy to get, it is at low cost.

Description

A kind of suck-back device for DMT 620M
Technical field
The utility model belongs to preclinical medicine research equipment technical field, and in particular to a kind of for the anti-down of DMT620M Inhale device.
Background technique
Currently, the well known in vitro capilary tension detection system of DTM 620M can carry out the suction of bath waste liquid and bath oxygen Supply, and the two independent operating.But go to execute suction bath waste liquid movement in bath oxygen access failure, bath oxygen can be made Suck-back phenomenon is generated in gas supply pipe.The supply of oxygen is influenced, instrument is damaged, to influence experiment progress.
Utility model content
The purpose of the utility model is to provide a kind of suck-back devices for DMT 620M, solve and deposit in the prior art The in vitro capilary tension detection system oxygen feeding pipe of DMT 620M in generate suck-back, influence the supply of oxygen, damage instrument Device, thus the problem of influencing experiment progress.
The utility model is including inverted the technical scheme adopted is that a kind of suck-back device for DMT 620M Cone shell, upper part of the housing offer venthole, and venthole is fixedly connected escape pipe.The tip of cone shell offers Air inlet, air inlet are fixedly connected air inlet pipe.Ball is provided in shell, and the path length of ball is greater than the diameter of air inlet Long, the path length of ball is greater than the path length of venthole.
The utility model is also characterized by:
It further include shell, conical shell is set in shell, and shell is fixedly connected with shell.
Shell is cube.
The base circumference line of shell and the four edges of upper surface of outer cover are tangent.
Shell and shell are integrally formed.
Venthole is consistent with the path length of air inlet.
The beneficial effects of the utility model are:
When air inlet pipe connects oxygen, ball is blown afloat oxygen by oxygen stream to flow out from escape pipe.When air inlet pipe does not connect When leading to oxygen or having inverted draft to pass through, ball is due to gravity or inverted draft effect is by air inlet hole plug makes inverted draft It cannot pass through, to realize unidirectional air guide and anti-suck.And whole device structure is simple, performance is stable, material is easy to get, cost It is low.
Detailed description of the invention
Fig. 1 is middle part sectional view of the utility model for the suck-back device main view of DMT 620M;
Fig. 2 is middle part sectional view of the utility model for the suck-back device left view of DMT 620M;
Fig. 3 is top view of the utility model for the suck-back device of DMT 620M.
In figure, 1. shells, 2. ventholes, 3. escape pipes, 4. air inlets, 5. air inlet pipe, 6. balls, 7. shells.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of suck-back device for DMT 620M, including inverted conical shell 1,1 top of shell offer out Stomata 2, venthole 2 are fixedly connected escape pipe 3.The tip of conical shell 1 offers air inlet 4, and air inlet 4 is fixedly connected Air inlet pipe 5.Ball 6 is provided in shell 1, and the diameter of ball 6 is greater than the diameter of air inlet 4, the diameter of ball 6 Greater than the diameter of venthole 2.
It is further:
It further include shell 7, conical shell 1 is set in shell 7, and shell 1 is fixedly connected with shell 7.
It is further:
Shell 7 is cube.
It is further:
The base circumference line of shell 1 and the four edges of 7 upper surface of shell are tangent.
It is further:
Shell 1 and shell 7 are integrally formed.
It is further:
Venthole 2 is consistent with the diameter of air inlet 4.
Preferred embodiment of the utility model for the suck-back device of DMT 620M are as follows:
As shown in Figure 1, include square body case 7, it is inverted setting conical shell 1 in square body case 7, shell 1 and outer Shell 7 is fixedly connected, and square body case 7 is integrally formed with inverted conical body shell body 1, on the base circumference line and shell 7 of shell 1 The four edges on surface are tangent (as shown in Figure 3).1 top of shell offers venthole 2, and venthole 2 is fixedly connected escape pipe 3 (as shown in Figure 2).The tip of conical shell 1 offers air inlet 4, and air inlet 4 is fixedly connected air inlet pipe 5.Venthole 2 with The diameter of air inlet 4 is consistent.Ball 6 is provided in shell 1, and the diameter of ball 6 is greater than the diameter of air inlet 4, namely The diameter of ball 6 is greater than the diameter of venthole 2.
The working process of the utility model is as follows: the suck-back device that the utility model is used for DTM 620M is accessed into DMT The bath oxygen air induction hose of the in vitro capilary tension detection system of 620M, when air inlet pipe 5 connects oxygen, oxygen stream is by rubber Ball blows afloat oxygen and flows out from escape pipe 3.When air inlet pipe 5 disconnects oxygen or has inverted draft to pass through, ball 6 is made because of gravity With or inverted draft effect by air inlet 4 blocking prevent inverted draft from passing through, to realize unidirectional air guide and anti-suck.
