420 bottom of switch member is fitted into the switch inner cylinder 301 of switch cylinder 300, and solid with the switch assembly of inner cylinder 301
Fixed, sealing；
It is provided with stroke block 310 on 300 outside of the switch cylinder, stroke block 310 is located at the first retention bead 211, the
Between two retention beads 212, the first retention bead 211, the second retention bead 212 are used to limit the angle of rotation of stroke block when use
Degree, thus limit switch cylinder rotational angle, that is, 420 rotational angle of limit switch part.
301 bottom of switch inner cylinder and the assembly of lower collar 430 are fixed, and are provided with lower shaft hole 431 in lower collar 430,
And in switch inner cylinder 301,430 lower section of lower collar also be in charge of the sealing of part 140 assembly, fixed, be in charge of in part 140 and pass through reticle
142, which are divided into two disconnected water conservancy diversion, divides chamber 141, two water conservancy diversion divide chamber 141 respectively with the first branch pipe 120, the second branch pipe 130
One end connection, the first branch pipe 120,130 other end of the second branch pipe are for being intubated and (being equivalent to nasogastric tube).In use, the first branch pipe
120, the second branch pipe 130 is respectively used to water conservancy diversion nutrient solution, medical fluid.
The upper shaft hole 411 is rotatably assembled with 440 one end of shaft, and 440 other end of shaft is after axle sleeve 423 under
Axis hole 430 rotatably assembles, so that switch cylinder 300 can be circumferentially rotated centered on shaft 440, to drive switch member
420 rotate synchronously；
It is provided with switch inner hole 421 in switch member 420, switchs in inner hole 421 and is fixed with enclosure portion 422, in use, envelope
Water conservancy diversion is divided chamber 141 to close by closing part points 421, that is, in actual use, the first branch pipe 120, the second branch pipe 130 can only select one with
Inlet tube 110 is connected to；The axle sleeve 423 is fixed in enclosure portion 421.
Preferably, two water conservancy diversion divide 141 section of chamber the same, and can cooperate respectively with enclosure portion 421, sealing.This just makes
The first branch pipe 120, the second branch pipe 130 can only select one and are connected to inlet tube 110 and be possibly realized.
Preferably, when enclosure portion 422 with and the water conservancy diversion that is connected to of the first branch pipe 120 divide chamber 141 to seal when, switch inner hole
421 with and the water conservancy diversion that is connected to of the second branch pipe 130 divide chamber 141 to be connected to, at this point, stroke block 310 contacted with the second retention bead 212 or
It is adjacent to；
When enclosure portion 422 with and the water conservancy diversion that is connected to of the second branch pipe 130 divide chamber 141 to seal when, switch inner hole 421 with and the
The water conservancy diversion of one branch pipe 120 connection divides chamber 141 to be connected to, at this point, stroke block 310 is contacted or is adjacent to the first retention bead 211.
This design so that, can directly pass through the first retention bead 211, the second retention bead 212 and stroke block 310 it
Between relationship can judge that inlet tube is connected to the first branch pipe 120 or the second branch pipe 130 at this time, so that operator be facilitated to make
With, judgement.
Preferably, water conservancy diversion inclined-plane 4221 is provided in the enclosure portion 422, the water conservancy diversion inclined-plane is in enclosure portion
It is tilted to down on 422 from above, inclined direction is to move closer to axle sleeve 423.This design is so that when practical practical, water conservancy diversion inclined-plane
4221 can sufficiently guide liquid to the first branch pipe 120 or the second branch pipe 130 being connected to switch inner hole 421, to avoid
Liquid buildup causes conveying capacity insufficient, influences the treatment of patient, or generates refluence when inlet tube is in low level.
Preferably, referring to Fig. 9, when being not used in order to prevent, liquid guide flow in abdomen is caused to go out since inlet tube is in low level
Inlet tube, the utility model are improved as follows:
Divide in chamber 141 in two water conservancy diversion and fix baffle ring 143, diaphragm seal 144 respectively, described 144 one end of diaphragm seal with point
Partition is connected and fixed, seals, and the other end is open end, and baffle ring 143 is located at 144 top of diaphragm seal, is used for baffle seal piece
144 are rotated up, and when diaphragm seal is rotated up 143 end face seal of Shi Huiyu baffle ring.
The diaphragm seal 144 has elasticity, when original state, be adjacent to, seal with baffle ring end face, in conveying medical fluid
When, the pressure of liquid opens diaphragm seal, and flexible deformation occurs for diaphragm seal, to carry out liquid conveying.When not in use, diaphragm seal
144 are adjacent to baffle ring by own resilient, abdomen air pressure (stomach or enteron aisle air pressure), are sealed, so as to prevent from flowing backwards.When
So, the necessary very little of pressure for needing to open diaphragm seal 144, not so will cause liquid buildup above diaphragm seal 144, plays anti-work
With.The present embodiment selects cracking pressure to be not more than 1.05 atmospheric pressure.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
