Referring to fig. 1-4, the present embodiment provides an adjustable position-limiting abdominal puncture device, which includes a puncture needle 1, and a connection port 2 is fixedly connected to an upper end of the puncture needle 1.
Wherein, pjncture needle 1 is arranged in puncturing the belly, penetrates in the peritoneal cavity, and connector 2 is used for connecting equipment to absorb the peritoneal effusion or connect the medicament bottle and pour into the medicament into the peritoneal cavity through pjncture needle 1.
In order to fix the puncture needle 1 which is inserted into the human body and prevent the puncture needle 1 from slipping off from the puncture hole, the outer side wall of the puncture needle 1 is provided with a balloon 3.
Wherein, 1 lateral wall of pjncture needle is seted up the recess and is located the lower extreme of 1 lateral wall of pjncture needle, and 3 fixed mounting of gasbag are inside the recess, and 3 preferred adoption medical rubber materials of gasbag have certain elasticity, can swell through aerifing the back, and 3 blocks of gasbag that swell are at the abdominal cavity, make pjncture needle 1 fix at the human body.
In order to facilitate the puncture of the air bag 3 into the human body along with the puncture needle 1, the air bag 3 is retracted when the air bag is not inflated, the retracted air bag 3 is completely immersed into the groove, and the outward surface of the air bag 3 is flush with the outer side wall of the puncture needle 1.
In order to conveniently inflate the air bag 3, an air hole 31 communicated with the air bag 3 is formed in the wall of the puncture needle 1, an air pipe 7 is connected to the upper end of the air hole 31, the air pipe 7 is communicated with the air hole 31 and fixedly connected to the outer side wall of the connector 2, the other end, away from the air hole 31, of the air pipe 7 is connected with an air nozzle 71, and the air nozzle 71 is communicated with the air pipe 7 and fixedly connected to the outer side wall of the connector 2.
The air pipe 7 is used for connecting an air pump, the model of the air pump is MJCQB01QJ, and the air pump can inflate or inhale air, so that the air bag 3 can expand and swell or contract conveniently.
In order to prevent the puncture needle 1 from puncturing too deeply, the outer side wall of the puncture needle 1 is sleeved with a sliding ring 5, the upper end of the sliding ring 5 is provided with a through hole 51 for the puncture needle 1 to pass through, the lower part of the sliding ring 5 is connected with a limiting ring 4, and the joint of the sliding ring 5 and the limiting ring 4 is provided with a connecting rod 41.
Wherein, the lateral wall at slip ring 5 is connected to the one end of connecting rod 41, and the other end is connected on the inner circle lateral wall of spacing ring 4, and in order to make the connection more firm, connecting rod 41 sets up to two, lies in the both sides of slip ring 5 respectively.
The lateral wall at pjncture needle 1 is cup jointed equally to spacing ring 4, but not with pjncture needle 1 contact, the bottom surface of spacing ring 4 is used for contacting with the human body, in order to make more comfortable with the human body contact, and prevent that spacing ring 4 from sliding on the human body, the lower extreme fixedly connected with second cushion 43 of spacing ring 4, second cushion 43 is preferred to set up to the rubber material, certainly not limited to the rubber material, still can adopt latex material etc. as long as comparatively soft, have certain elasticity, and with the great material of human coefficient of friction all can.
The position of stop collar 4 at 1 lateral wall of pjncture needle can be fixed to the slip ring 5 is fixed, and the 1 needle tubing of pjncture needle that lies in the exposure of 4 below of stop collar this moment is the length that gets into the human body for the puncture, and for the convenience of observing the depth of penetration, the lateral wall of pjncture needle 1 is provided with the scale.
