Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
Example 1:
referring to fig. 1 to 10, the present embodiment provides an insufflation valve for a puncture outfit, including: a valve body 100, a valve cartridge assembly disposed within the valve body 100, and a bonnet 400 adapted to be coupled to the valve body 100.
Specifically, firstly, the valve body 100 has a hollow accommodating cavity 101, and the valve body 100 is provided with an air inlet 102 adapted to inflate the accommodating cavity 101, an air outlet 103 adapted to discharge air in the accommodating cavity 101, and an air outlet 105 communicated with the accommodating cavity 101 and used for connecting a puncture outfit; that is, here, the gas inlet 102, the gas outlet 105 and the gas outlet 103 are all communicated with the accommodating cavity 101, and the accommodating cavity 101 forms a passage for gas to flow through.
Secondly, the valve core assembly comprises a first sealing piece suitable for blocking the air outlet 103, a second sealing piece suitable for blocking the air inlet 102, and an elastic piece 200 arranged between the first sealing piece and the second sealing piece; in conjunction with the drawings of the present embodiment, the elastic member 200 of the present embodiment is exemplified by a spring. Under the natural elastic state of the spring, that is, under the premise of not receiving the external force, the spring can generate the pushing force for the first sealing element and the second sealing element, so that the first sealing element can block the exhaust port 103, and the second sealing element can block the intake port 102. When the first sealing member is applied with an acting force to compress the spring, the blocking effect of the first sealing member on the exhaust port 103 is eliminated, and at this time, the gas in the accommodating cavity 101 can be discharged through the exhaust port 103, and similarly, when the second sealing member is applied with an acting force to compress the spring, the blocking effect of the second sealing member on the gas inlet 102 is eliminated, and at this time, the gas can be introduced into the accommodating cavity 101 through the gas inlet 102.
Further, the valve cap 400 is sealingly coupled to the valve body 100, and the valve cap 400 has a hollow through hole 403 communicating with the air inlet 102. The sealing engagement of the valve cover 400 with the valve body 100 makes it possible here to vent gas into the receiving chamber 101 of the valve body 100 only through the through-opening 403,
in view of convenience and high efficiency in the air intake operation of the valve body 100, the present embodiment adopts the following structure:
the inflation valve further comprises an adapter adapted to be coupled to the valve cap 400, wherein the adapter is adapted to be coupled to a pneumoperitoneum machine, i.e., the inflation of the valve body 100 by the pneumoperitoneum machine is achieved through the adapter.
In detail, referring to the drawings of the present embodiment, the adapter includes a cylindrical connecting portion 301 for being coupled to the valve cover 400, and an ejecting portion 302 penetrating the cylindrical connecting portion 301 and adapted to be inserted into the through hole to press the elastic member 200 after abutting against the second sealing member; wherein the pushing part 302 is internally penetrated with a hollow gas channel 303 suitable for air intake.
It should be noted that, after the adapter is coupled to the valve cover 400, the pushing portion 302 at this time just abuts against the second sealing member, and the second sealing member at this time is pushed against the elastic member 200 under the pushing action of the pushing portion 302, so that the elastic member 200 is compressed and deformed, in this process, the blocking effect of the second sealing member on the gas inlet 102 is synchronously eliminated, so that the gas introduced into the gas passage 303 of the pushing portion 302 can smoothly enter the accommodating cavity 101 of the valve body 100 through the gas inlet 102. After the adapter and the valve cover 400 are detached, the pushing action of the pushing part 302 on the second sealing element is synchronously eliminated, and at this time, the second sealing element naturally recovers the sealing effect on the air inlet 102 under the elastic restoring action of the elastic element 200.
In addition, the adapter further comprises an air inlet pipe 305 connected with the columnar connecting part 301 and suitable for being communicated with the air channel 303; the intake pipe 305 has a straight pipe structure or a bent pipe structure. Here, the gas inlet pipe 305 is used for connecting a pneumoperitoneum machine, and gas in the pneumoperitoneum machine passes through the gas inlet pipe 305 and then enters the gas passage 303 of the pushing part 302, so as to enter the accommodating cavity 101 of the valve body 100.
The matching between the valve cover 400 and the adapter is realized by the following specific means: the outer side wall of the valve cover 400 is provided with a clamping groove 401 with an annular structure; and the inner side wall of the columnar connecting part 301 is provided with an annular bulge 306 suitable for being in clamping fit with the clamping groove 401. That is, the sealing engagement between the valve cap 400 and the adapter is achieved by the engagement of the locking groove 401 and the annular protrusion 306. Of course, the valve cover 400 and the adapter may be realized by a screw-coupled structure, and this embodiment is not limited in this respect.
In order to further improve the sealing effect of the valve cover 400 in the state of being matched with the adapter, a first sealing ring 800 is further embedded in the axial matching position of the columnar connecting part 301 and the valve cover 400.
In addition, the second sealing element and the first sealing element of the present embodiment include a second base 501 adapted to block the air inlet 102, and a second cylindrical protrusion 503 integrally connected to one side end of the second base 501 facing away from the pushing part 302; the pushing part 302 is suitable for abutting against the second base 501; and the second cylindrical protrusion 503 is adapted to be embedded in the elastic member 200. The first sealing element comprises a first base body 601 suitable for blocking the exhaust port 103, a convex column 602 which is connected with the first base body 601 and is suitable for penetrating through the rear part of the exhaust port 103 and partially extending out of the valve body 100, and a first columnar bulge 603 which is integrally connected with one side end of the first base body 601, which is far away from the convex column 602; the first stud bump 603 is adapted to be embedded in the elastic member 200.
It should be noted that, because the convex pillar 602 included in the first sealing member of the present embodiment partially protrudes outside the valve body 100, the pushing action for the first sealing member moving toward the elastic member 200 can be realized only by pushing the end of the convex pillar 602 protruding outside the valve body 100 by a hand. That is to say, when the gas in the accommodating cavity 101 of the valve body 100 needs to be discharged, only a certain pushing force needs to be applied to the end of the convex pillar 602 extending out of the valve body 100 by the fingers, so that the first sealing member compresses the elastic member 200, and the sealing effect of the second sealing member on the blocking of the gas outlet 103 disappears, so that the gas in the valve body 100 can be discharged through the gas outlet 103.
On the basis of the above structure, in view of further improving the smoothness in the exhaust process, the present embodiment further has a plurality of vent grooves 107 recessed in the valve body 100 along the circumferential direction of the exhaust port 103 around the outer side wall of the exhaust port 103.
In an alternative embodiment, in order to further improve the sealing and matching effect between the first sealing element and the exhaust port 103 in the natural elastic state of the elastic element 200, a second sealing ring 700 is further embedded at the axial matching position of the end surface of the first base 601, which is away from the first columnar protrusion 603, and the valve body 100.
The specific implementation principle of the air injection valve of the embodiment is as follows:
when the valve cover 400 of the gas injection valve is not connected with the adapter, the valve cover 400 is hermetically connected with the valve body 100, and the gas outlet 105 of the valve body 100 is hermetically connected with the puncture sleeve 900 of the puncture outfit. At this time, when the elastic member 200 is in a natural elastic state, the first sealing member blocks the exhaust port 103, and the second sealing member blocks the intake port 102, so that a sealed cavity is formed inside the valve body 100 as a whole. The gas injection valve in this state is in a sealed state, if a pushing action is applied to one end of the convex column 602 of the first sealing element extending out of the valve body 100 by a hand at this time, the first sealing element moves towards the direction of the second sealing element by overcoming the action of the elastic element 200 under the action of the hand, and at this time, the sealing and blocking effect between the first sealing element and the gas outlet 103 disappears, so that gas in the valve body 100 can freely enter and exit from the gas outlet 103 of the valve body 100.
When the adapter is connected to the valve cover 400 of the gas injection valve (the adapter is connected to the pneumoperitoneum machine), the adapter is connected with the valve cover 400 in a buckling mode, meanwhile, the pushing portion 302 of the adapter pushes the second sealing element towards the first sealing element, so that the sealing effect of the second sealing element on the blocking of the gas inlet 102 disappears, and at the moment, gas can enter the gas channel 303 of the pushing portion 302 from the gas inlet pipe 305 of the adapter and finally enters the accommodating cavity 101 of the valve body 100 through the gas inlet 102 of the valve body 100. The gas injection valve in this state is in an inflated state, if a pushing action is applied to one end of the convex column 602 of the first sealing element extending out of the valve body 100 by a hand at this time, the first sealing element moves towards the direction of the second sealing element by overcoming the action of the elastic element 200 under the action of the hand, and at this time, the sealing and blocking effect between the first sealing element and the gas outlet 103 disappears, so that gas in the valve body 100 can freely enter and exit from the gas outlet 103 of the valve body 100. On the premise that the valve body 100 does not need to be inflated, the adapter and the valve cover 400 only need to be detached.
Example 2:
the puncture outfit of the present embodiment includes the air injection valve of embodiment 1 on the basis of the air injection valve of embodiment 1.
In the use process of the puncture outfit of the embodiment, the puncture needle is inserted into the puncture sleeve 900, penetrates the skin to establish a channel, and then is pulled out, at this time, the air injection valve of the puncture outfit is closed, other surgical instruments can enter the body through the puncture sleeve 900 to perform the surgical operation, and if air needs to be released, the convex column 602 of the first sealing element can be manually pressed to extend out of one end of the valve body 100 for releasing air. If the pneumoperitoneum machine needs to be connected to the puncture ware, then be connected the intake pipe 305 and the pneumoperitoneum machine trachea of adapter earlier, be connected adapter and valve gap 400 again, connect back valve body 100 and open, in case adapter and valve gap 400 are connected promptly, the valve body 100 of gas injection valve will directly put through, need not manually to open, the pneumoperitoneum machine can be aerifyd to internal this moment, if need to deflate, then the projection 602 that can manually press first sealing member stretches out the one end outside valve body 100 and deflates.
