Description

[0002] In actual animal experiments, animal gastric function experiments are common experimental projects. When conducting actual gastric examinations, it is often necessary to deflate the animal's rumen to prevent continuous stomach distension and to facilitate subsequent surgical operations. During actual operations, the animal needs to be fixed to prevent the needle from continuously deflation from injuring the animal. Current experimental animal surgical fixation equipment has limited fixation effects on large animals. Animals will inevitably experience stress movements, which is not convenient for automatically detecting animal movements and controlling needle removal, which can easily cause animal damage. At the same time, in actual animal rumen deflation work, it is very easy to cause excessive discharge of a large amount of gastric juice from the animal, which directly further damages the animal's gastric function.

Press the delay switch 5011 to control the electric heating wire at the end of the electric heating tube 302 to be quickly energized and heated. The electric heating wire at the end of the electric heating tube 302 uses the same heating wire as an electric lighter. At this time, the stop electromagnet 201 will also magnetically attract the stop column 202 to retract. Only then can the deflation puncture needle 301 be normally inserted into the closing cover 102 and puncture into the animal's stomach to exhaust.

[0034] The deflation puncture member 3 further comprises: a sponge mounting shell 3012, a sponge liquid absorbing pad 303 and a conductive ring 304. The sponge mounting shell 3012 is fixedly mounted on the deflation puncture needle 301; the sponge liquid absorbing pad 303 is fixedly mounted inside the sponge mounting shell 3012; the sponge liquid absorbing pad 303 is used to absorb gastric fluid; two conductive rings 304 are fixedly mounted inside the sponge mounting shell 3012, and a distance is provided between the two conductive rings 304; the sponge liquid absorbing pad 303 is attached to the two conductive rings 304; the puncture bullet The ejection element 4 includes: a pop-up limiting cylinder 401 and a needle withdrawal spring 402. The pop-up limiting cylinder 401 is slidably sleeved on the closure cover 102; the outer bottom of the pop-up limiting cylinder 401 is a sloped structure; the inner part of the pop-up limiting cylinder 401 is sleeved with the needle withdrawal spring 402; the end of the needle withdrawal spring 402 is connected to the inner side of the pop-up limiting cylinder 401; the other end of the needle withdrawal spring 402 is connected to the closure cover 102; an annular positioning groove is provided on the outer side of the pop-up limiting cylinder 401; the needle handle raised ring 3011 is overlapped on the pop-up limiting cylinder 401 ; The pop-up limit cylinder 401 is used to push out the raised ring 3011 of the needle handle; the limit member 5 includes: a fixed mounting ring 501, a delay switch 5011, a needle-pulling electromagnet 502, and a pop-up limit column 503. The fixed mounting ring 501 is fixedly mounted on the closure cover 102; the pop-up limit cylinder 401 is slidably sleeved on the fixed mounting ring 501; a delay switch 5011 is fixedly mounted on the fixed mounting ring 501; the delay switch 5011 is electrically connected to the electric heating wire at the front end of the electric heating tube 302 and the stop electromagnet 2 01; A circle of needle-pulling electromagnets 502 is fixedly installed inside the fixed mounting circle 501, and the circle of needle-pulling electromagnets 502 are respectively connected in series with the two conductive rings 304 to a battery power source; a circle of pop-up limiting posts 503 are slidably inserted inside the fixed mounting circle 501, and the circle of needle-pulling electromagnets 502 are respectively aligned with the circle of pop-up limiting posts 503; springs are respectively fixedly installed at the front ends of the circle of needle-pulling electromagnets 502, and the spring ends at the front ends of the circle of needle-pulling electromagnets 502 are connected to the tails of the pop-up limiting posts 503 on the same side;The ends of a circle of pop-up limit columns 503 are respectively inserted into the annular grooves on the outer side of the pop-up limit cylinder 401. The limiter 5 can realize automatic control to withdraw the deflation puncture needle 301. Once the deflation puncture needle 301 is actually deflated and the gastric juice is released, it can be automatically controlled to ensure the timeliness of needle withdrawal. Especially for large animals, such as cattle, the actual deflation time is relatively long, and it is very easy to forget to remove the needle manually, resulting in a large amount of gastric juice discharge. The loss of gastric juice will reduce the action time of digestive enzymes and acidic environment, affect the efficiency of food decomposition, and further lead to malnutrition or indigestion. This structure can realize automatic detection and discharge, and the structural control is direct, which improves the safety of animal experiments and reduces To prevent damage, if gastric fluid flows through the deflation puncture needle 301 during actual deflation and leakage occurs, the gastric fluid will be absorbed by the sponge absorbent pad 303. Gastric fluid itself contains a large amount of electrolytes, which will cause the two conductive rings 304 to conduct, thus energizing the needle. At this time, when the needle removal electromagnet 502 is energized, it will magnetically attract the pop-up limit post 503, compressing the spring at the end of the pop-up limit post 503, and extracting it from the positioning groove on the pop-up limit cylinder 401, thus releasing the positioning. Under the push of the needle withdrawal spring 402, the pop-up limit cylinder 401 is quickly ejected, pushing the needle handle raised ring 3011 to drive the deflation puncture needle 301 out of the animal's stomach, thus preventing continuous discharge of gastric fluid.

[0035] Example 2, based on Example 1, the fixed detection member 6 includes: a restraint belt 601 and a detection mounting shell 602, the end of the restraint belt 601 is fixedly mounted on the traction ring 104 on the same side; the other end of the restraint belt 601 is provided with a fleece-surface Velcro and a needle-surface Velcro; the other end of the restraint belt 601 is used to pass through another traction ring 104; the restraint belt 601 is fixedly restrained on the abdomen of the animal; the restraint belt 601 is an elastic belt; a detection mounting shell 602 is fixedly mounted on the side of the restraint belt 601; the fixed detection member 6 includes: a sliding The movable limit column 603 and the electric ring 604, the sliding limit column 603 is slidably inserted into the detection installation shell 602; a tension spring is sleeved on the sliding limit column 603; the tension spring sleeved on the sliding limit column 603 is connected between the sliding limit column 603 and the detection installation shell 602; there are two electric rings 604, which are fixedly mounted on the sliding limit column 603 and the detection installation shell 602 respectively; the two electric rings 604 are aligned; the two electric rings 604 and the needle-pulling electromagnet 502 are connected in series with the battery power supply ; The two power rings 604 are respectively located on the inner side of the detection mounting shell 602; the fixed detection member 6 also includes: a fixed rope 605, and a fixed rope 605 is fixedly installed on the sliding limit column 603. The use of the fixed detection member 6 can further ensure that the present structure can stably fix the positioning mounting shell 101, maintain the stability of the deflation puncture needle 301, and prevent the deflation puncture needle 301 from shaking or falling off. At the same time, the fixed rope 605 can be wound around the railings in the cowshed or on the experimental operating table to further limit the animal's activities. The range of the animal is large, which improves the stability of the actual deflation and can realize automatic monitoring. Once the animal moves abnormally, the structure can realize automatic control of the needle withdrawal to prevent the deflation puncture needle 301 from damaging the animal's internal organs. When the animal moves abnormally in a large range, the restraint belt 601 will be pulled. At this time, the sliding limit column 603 slides on the detection mounting shell 602, and the two power rings 604 are attached to each other, so as to control the needle removal electromagnet 502 to be electromagnetically sucked out again to eject the limit column 503, thereby controlling the deflation puncture needle 301 to be withdrawn from the animal's stomach.

[0036] The working principle of this embodiment: First, shave the animal's hair locally, stick the double-sided tape at the bottom of the positioning and mounting shell 101 to the animal's skin, and keep the installation position of the positioning and mounting shell 101 at a relatively horizontal position so that the insertion angle of the deflation puncture needle 301 is kept. At the same time, the restraint belt 601 needs to be passed through the traction ring 104, and the fur-side Velcro and needle-side Velcro provided at the other end of the restraint belt 601 are pasted together to keep the restraint belt 601 tied to the animal's abdomen. Wrap the fixing rope 605 around the railings in the cowshed or on the experimental operating table to limit the animal's range of activity. Then, press the delay switch 5011 to control the electric heating wire at the end of the electric heating tube 302 to quickly energize and heat it. The electric heating wire at the end of the electric heating tube 302 can be the same heating wire as that of an electric lighter. When the stop electromagnet 201 is turned off, the stop post 202 will be magnetically attracted to retract, and the spring at the tail of the stop post 202 will be compressed, so that the through hole on the closing cover 102 is no longer blocked. At this time, the deflation puncture needle 301 can be normally inserted into the closing cover 102 and punctured into the stomach of the animal to exhaust. At this time, the magnet ring 103 magnetically attracts the raised ring 3011 of the needle handle. At this time, as the gas in the stomach is discharged from the deflation puncture needle 301, it can be ignited by the electric heating wire at the end of the electric heating tube 302, and the methane can be continuously consumed in conjunction with the real-time discharge of gas. On the contrary, if the heating of the electric heating wire at the end of the electric heating tube 302 is not controlled, the stop post 202 can be inserted into the closing cover 102 for stopping under the compression of the spring at the tail of the stop post 202. At this time, the deflation puncture needle 301 cannot perform the puncture work normally, thereby achieving the restriction work.

[0037] When the deflation puncture needle 301 is actually deflated, if gastric juice flows through the deflation puncture needle 301 and leakage occurs, the gastric juice will be absorbed by the sponge absorbent pad 303. The gastric juice itself contains a large amount of electrolytes, which will cause the two conductive rings 304 to be conductive and energized. At this time, after the needle removal electromagnet 502 is energized, the limit post 503 will be magnetically attracted to pop out, and the spring at the tail of the limit post 503 will be compressed and pulled out from the positioning groove on the pop-up limit cylinder 401 to release the positioning. Under the push of the needle withdrawal spring 402, the limit cylinder 401 will pop out quickly, pushing the needle handle raised circle 3011 to drive the deflation puncture needle 301 to be pulled out from the animal's stomach, avoiding continuous discharge of gastric juice. If you want to reuse it later, press the pop-up limit The positioning cylinder 401 moves downward to compress the needle withdrawal spring 402, and at the same time, the pop-up limit cylinder 401 uses the outer inclined surface structure to smoothly insert the fixed mounting ring 501 again and insert the pop-up limit cylinder 401 for positioning through the pop-up limit column 503, and this structure needs to be fully disinfected; when the animal moves in a large range, the restraint belt 601 will be pulled to drive the detection mounting shell 602 to move, causing the tension spring on the sliding limit column 603 to be stretched. At this time, the sliding limit column 603 slides on the detection mounting shell 602, and the two power rings 604 are attached to each other, so as to control the needle removal electromagnet 502 to be electromagnetically attracted again to pop out the limit column 503, so as to control the deflation puncture needle 301 to be withdrawn from the animal's stomach for protection.
