Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of animal temperature detection, and particularly relates to a veterinary animal temperature detection device. BACKGROUND

[0002] Veterinary animal temperature detection refers to a technical means for judging the health condition or early signs of diseases by measuring the body temperature of animals. For large livestock such as cattle, body temperature is an important indicator of physiological state. Abnormal body temperature often indicates the occurrence of diseases such as mastitis, respiratory diseases (BRDc) or heat stress.

[0003] At present, veterinary temperature detection mainly relies on rectal temperature measurement, infrared temperature measurement and electronic thermometer implantation. Infrared temperature measurement indirectly judges the body temperature by measuring the surface temperature of the animal. However, the accuracy of animal temperature detected by infrared rays is not high enough, and only the surface temperature can be reflected, which is different from the core body temperature. The surface temperature of the animal is higher when it is moving, and it is difficult to truly reflect the actual body temperature of the animal by measuring the surface temperature when it is stationary. Rectal temperature measurement is the most commonly used method at present, but the thermometer needs to be inserted into the rectum of the animal and kept for a certain period of time, which can easily cause stress reaction of the animal and is inconvenient to operate. Although electronic thermometer implantation can monitor the body temperature of cattle, the existing electronic thermometer has the problems of poor fixation, easy falling off, and cannot guarantee long-term stable monitoring. In addition, there is a lack of effective health protection measures, and there are certain defects. Therefore, it is necessary to develop a veterinary animal temperature detection device. SUMMARY

[0004] In view of the above-mentioned defects and problems, the present application provides a veterinary animal temperature detection device, which aims to realize fast and stable implantation of the thermometer by mechanical linkage structure, prevent the falling off of the indwelling thermometer by using the expansion of the air bag sleeve and the locking of the stop component, and ensure the operation hygiene by the sanitary film sleeve.

[0005] The technical problem is solved by the following scheme: a veterinary animal temperature detection device, comprising a implanting assembly, a indwelling thermometer, a stop assembly and a sanitary film cover, the implanting assembly comprises an implanting device, a push-pull unit, a push rod, L-shaped outer springs, an outer sleeve and an outer spring, an output pipe is installed at the output end of the implanting device, the output pipe is sleeved with a guide pipe, the outer sleeve is sleeved on the output pipe and can be elastically pushed by the outer spring, a plurality of L-shaped outer springs are evenly distributed on the side of the port of the output pipe, the outer sleeve can press the L-shaped outer springs, the front end of the L-shaped outer springs is buckled to the edge of the port of the guide pipe, and the port of the guide pipe is blocked; the push-pull unit is used for controlling the push rod to move forward and backward in the guide pipe, and a triangular clamping piece is installed at the front end of the push rod; the indwelling thermometer comprises a shell, a temperature sensor, a fixing sleeve, a rear sleeve, an air bag sleeve, a rear end plate and a core rod, the temperature sensor arranged in the shell is used for detecting body temperature, the fixing sleeve and the rear sleeve are sleeved on the shell in front and back respectively, and the rear sleeve can slide relative to the shell, the air bag sleeve is sealingly arranged between the fixing sleeve and the rear sleeve, and the rear sleeve can slide axially to compress the air bag sleeve, so that the air bag sleeve expands radially; the rear end plate is fixed at the rear end of the shell, the core rod is fixed on the rear end plate along the axis, and a ball head is installed at the rear end of the core rod, the ball head can be matched with the triangular clamping piece; the stop assembly comprises a push tube, an elastic sleeve and a conical sleeve, the push tube is connected with the rear end of the rear sleeve, a plurality of reverse teeth are evenly distributed on the radial side wall of the inner wall of the push tube, the elastic sleeve is sleeved in the rear end of the shell, and the conical sleeve is sleeved on the core rod, the conical sleeve can outwardly support the elastic sleeve, so that the rear end of the elastic sleeve is clamped with the reverse teeth to stop and lock the rear sleeve.

[0006] (1) The radial contraction / expansion of the L-shaped outer spring is controlled through the cooperation of the outer sleeve and the outer spring, the dynamic blocking of the port of the guide pipe is realized, the L-shaped outer spring is compressed by the outer sleeve pushed by the outer spring in the natural state, which can make it shrink inward to block the port, when the outer sleeve is manually pulled, the L-shaped outer spring is elastically expanded, which can open the port of the guide pipe for inserting the indwelling thermometer; at the same time, the push-pull unit can control the push rod to move forward and backward, the indwelling thermometer can be quickly implanted in the body of the cow, the difficulty and error of manual operation are reduced, and the triangular clamping piece can automatically lock the ball head to ensure that the indwelling thermometer does not fall off during implantation; (2) The air bag cover of the indwelling thermometer can be compressed axially and expanded radially to form support on the inner wall of the cow anus, so as to ensure that the indwelling thermometer is stably indwelled in the cow body for a period of time. The radial expansion of the air bag cover is realized by the back pulling action of the push rod. Through the linkage of the L-shaped outer spring plate and the push tube, the front end of the L-shaped outer spring plate blocks the rear end of the push tube during the back pulling process of the push rod, so that the rear sliding sleeve can move axially forward, compress the air bag cover axially and expand it radially. The stop assembly can lock the rear sliding sleeve through the cooperation of the elastic sleeve and the conical sliding sleeve, so as to keep the air bag cover in the expanded state. At the same time, the triangular clamping piece is separated from the ball head during the back pulling process, so that the implanting device is separated from the indwelling thermometer, and the indwelling fixation of the indwelling thermometer is completed.

[0007] (3) When the indwelling thermometer is implanted, the sanitary film cover can enter the cow anus together with the indwelling thermometer, effectively isolating the direct contact between the indwelling thermometer and the cow body, ensuring the sanitation of the indwelling thermometer during implantation and removal, and preventing cross infection.

DETAILED DESCRIPTION

[0017] The application will be further described below in conjunction with the drawings and examples.

[0018] In the prior art, the detection of the body temperature of animals mainly depends on rectal temperature measurement, infrared temperature measurement and electronic thermometer implantation. The infrared temperature measurement indirectly judges the body temperature by measuring the surface temperature of the animal, but the accuracy of the animal body temperature detected by the infrared rays is not high, and only the surface temperature can be reflected, which is different from the core body temperature. When the animal is moving, the surface temperature is higher, and it is difficult to truly reflect the actual body temperature of the animal by measuring the surface temperature when the animal is stationary. The rectal temperature measurement is the most commonly used method at present, but the thermometer needs to be inserted into the rectum of the animal and kept for a certain period of time during the measurement, which easily causes the stress reaction of the animal and is inconvenient to operate. Although the electronic thermometer implantation can monitor the body temperature of the cow, the existing electronic thermometer has the problems of poor fixation, easy falling off, easy falling off from the animal body, inability to guarantee long-term stable monitoring, and lack of effective sanitary protection measures.

[0019] In view of the above problems, the present embodiment provides an animal body temperature detection device for veterinarians, which comprises an implanting assembly 1, an indwelling thermometer 2, a stop assembly 3 and a sanitary film sleeve 4, and aims to solve the problems of how to quickly implant the indwelling thermometer 2 in the cow body and keep it stable and not fall off for a period of time, and how to keep the hygiene before and after the indwelling thermometer 2 invades the anus of the cow, as shown in the figure. Figures 1-5 As shown in the figure, the implanting assembly 1 comprises an implanting device 11, a push-pull unit, a push rod 15, an L-shaped outer spring piece 17, an outer sliding sleeve 18 and an outer spring 19. The implanting device 11 is in the shape of an electric drill, an output pipe 12 is fixedly installed at the output end of the implanting device 11, a guide pipe 13 is fixedly sleeved in the output pipe 12, the indwelling thermometer 2 can be inserted into the guide pipe 13, and the guide pipe 13 provides guidance for the indwelling thermometer 2.

[0020] The outer sleeve 18 is slidably mounted on the output tube 12, and a spring seat 191 is fixed on the output tube 12. The outer spring 19 is installed on the spring seat 191. The outer sleeve 18 is connected to the outer spring 19. The outer sleeve 18 can be elastically pushed by the outer spring 19. A plurality of L-shaped outer spring pieces 17 are radially distributed around the port of the output tube 12. An embedding groove that matches the L-shaped outer spring piece 17 is opened on the outer peripheral side wall of the output tube 12. The rear end of the L-shaped outer spring piece 17 is fixed in the embedding groove by a screw. The outer sleeve 18 can compress the L-shaped outer spring piece 17 so that the front end of the L-shaped outer spring piece 17 is snapped onto the edge of the port of the guide tube 13, thereby blocking the port of the guide tube 13.

[0021] The L-shaped outer spring piece 17 is elastic, and each L-shaped outer spring piece 17 is in an outward-expanded state in a natural state. The sliding adjustment outer sleeve 18 can simultaneously compress the L-shaped outer spring piece 17, so that each L-shaped outer spring piece 17 is in an inward-contracted state. That is to say, when the outer sleeve 18 moves forward in the axial direction to compress the L-shaped outer spring piece 17, the L-shaped outer spring piece 17 can be synchronously contracted inwardly in the radial direction. At this time, the front end of the L-shaped outer spring piece 17 is snapped onto the edge of the port of the guide tube 13 to block the port of the guide tube 13; when the outer sleeve 18 moves backward in the axial direction to disengage from the L-shaped outer spring piece 17, under the self-elasticity of the L-shaped outer spring piece 17, the L-shaped outer spring piece 17 will synchronously expand outward in the radial direction, and the front end of the L-shaped outer spring piece 17 will disengage from the edge of the port of the guide tube 13 and no longer block the port of the guide tube 13.

[0022] In the initial state, the outer sleeve 18 is elastically pushed by the outer spring 19. At this time, the outer sleeve 18 simultaneously compresses the L-shaped outer spring piece 17 to make it contract radially inward. The front end of the L-shaped outer spring piece 17 is snapped onto the edge of the port of the guide tube 13 to block the port of the guide tube 13. When the outer sleeve 18 is manually pulled backward to separate the outer sleeve 18 from the L-shaped outer spring piece 17, the L-shaped outer spring piece 17 will simultaneously expand radially outward under its own elasticity and no longer block the port of the guide tube 13.

[0023] like Figures 3-5 As shown, the push-pull unit is arranged in the implanter 11, and is used to control the axial forward and backward telescopic movement of the push rod 15 in the guide tube 13. The push-pull unit includes a motor 141, a screw 142 and a screw sleeve 143. The motor 141 is fixedly installed in the implanter 11, and the output end of the motor 141 is connected to the screw 142. The screw sleeve 143 is sleeved on the screw 142. The front end of the screw sleeve 143 is provided with a hollow sleeve hole, and the rear end of the push rod 15 is sleeved in the hollow sleeve hole, and a guide plate 144 is connected to the circumference of the screw sleeve 143. A guide groove matching the guide plate 144 is provided in the guide tube 13, and the guide plate 144 is matched and sleeved in the guide groove. The motor 141 drives the screw 142 to rotate to control the axial movement of the screw sleeve 143, and then can synchronously drive the push rod 15 to telescopically move back and forth in the guide tube 13.

[0024] The triangular clamping piece 16 is installed at the front end of the push rod 15, and is provided with elastic triangular clamping jaws.

[0025] As shown in Figures 5-7 The indwelling thermometer 2 comprises a shell 21, a temperature sensor 23, a fixing sleeve 27, a rear sliding sleeve 28, an air bag sleeve 29, a rear end plate 24 and a core rod 25.

[0026] The fixing sleeve 27 and the rear sliding sleeve 28 are sleeved on the shell 21 in front and back respectively, and the rear sliding sleeve 28 can axially slide relative to the shell 21.

[0027] That is, the air bag sleeve 29 is initially in a flat state, and the air bag sleeve 29 has gas inside.

[0028] In order to improve the radial expansion effect of the air bag sleeve 29, an inner recessed section can be formed on the rear end of the shell 21.

[0029] As shown in Figures 6-7 The core rod 25 is fixed on the rear end plate 24 along the axis, and a ball head 26 is fixed at the rear end of the core rod 25.

[0030] The stop assembly 3 is used to stop and lock the rear sliding sleeve 28, when the rear sliding sleeve 28 axially compresses the air bag sleeve 29, makes the air bag sleeve 29 radially expand, and makes the indwelling thermometer 2 separate from the implanting device 11, and indwells in the anus of the cow, the air bag sleeve 29 can be kept in the expanded state; As Figure 7 The stop assembly 3 includes a push tube 31, an elastic sleeve 33 and a conical sleeve 34, the push tube 31 is fixedly connected with the rear end of the rear sliding sleeve 28, a plurality of reverse teeth 32 are uniformly distributed on the inner circumferential side wall of the push tube 31 in the radial direction, the elastic sleeve 33 is matched and sleeved on the inner rear end of the shell 21, the conical sleeve 34 is slidably sleeved on the core rod 25, and the conical sleeve 34 can slide forward and backward on the core rod 25, the conical sleeve 34 can be pushed into the elastic sleeve 33, the elastic sleeve 33 is outwardly supported, the rear end of the elastic sleeve 33 is clamped to the reverse teeth 32, and the rear sliding sleeve 28 is stopped and locked.

[0031] The elastic sleeve 33 has a self elastic function, the elastic sleeve 33 includes a elastic sheet plate 331 and a plurality of L-shaped inner elastic sheets 332, a through hole matched with the core rod 25 is formed on the axis of the elastic sheet plate 331, the plurality of L-shaped inner elastic sheets 332 are uniformly distributed on the elastic sheet plate 331 in the radial direction, and the L-shaped inner elastic sheets 332 are naturally inclined inward, when the L-shaped inner elastic sheets 332 are outwardly expanded by the conical sleeve 34, the rear end of the L-shaped inner elastic sheets 332 can be clamped to the reverse teeth 32, the elastic sleeve 33 can prevent the rear sliding sleeve 28 from moving backward when the rear sliding sleeve 28 moves axially forward, and the air bag sleeve 29 is kept in the radially expanded state.

[0032] The L-shaped inner elastic sheets 332 are in the state of being inwardly contracted in the natural state, the conical sleeve 34 can be pushed into the root of the elastic sleeve by a tool hook, each L-shaped inner elastic sheet 332 is outwardly expanded, the L-shaped inner elastic sheets 332 are in a straight line state, the rear end of the L-shaped inner elastic sheets 332 is clamped to the reverse teeth 32, the rear end of the L-shaped inner elastic sheets 332 has elasticity, when the push tube 31 moves forward with the rear sliding sleeve 28, the rear end of the L-shaped inner elastic sheets 332 is self-adapted to clamp the reverse teeth 32 of the push tube 31, and the conical sleeve 34 is tightly pushed into the elastic sleeve 33, and the conical sleeve 34 cannot be separated from the elastic sleeve 33 without external intervention, the conical sleeve 34 can be pulled out of the elastic sleeve 33 by the tool hook, the L-shaped inner elastic sheets 332 are reset, the L-shaped inner elastic sheets 332 are no longer outwardly expanded to clamp the reverse teeth 32, and the rear sliding sleeve 28 can freely slide.

[0033] The sanitary film sleeve 44 is closed at one end and open at the other end, and the open end is provided with a tightening belt, which is used to isolate the indwelling thermometer 2 implanted into the cow, and keep the indwelling thermometer 2 hygienic before and after invading the anus of the cow.

[0034] The device use process: the initial state of the indwelling thermometer 2 is not installed in the implantation device 11, first push the conical sleeve 34 to the elastic sleeve 33 by the tool hook, make the L-shaped inner elastic sheet 332 all outwardly expand; In the initial state, the triangular clamping piece 16 and the push rod 15 are located at the rear side, the tester manually slides the outer sleeve 18 backward, so that the outer sleeve 18 is separated from the L-shaped outer elastic sheet 17, at this time all the L-shaped outer elastic sheet 17 automatically expands outward, the front end of the L-shaped outer elastic sheet 17 is separated from the edge of the port of the guide pipe 13, and no longer blocks the port of the guide pipe 13, at this time the indwelling thermometer 2 is inserted into the guide pipe 13 of the implantation device 11 and partially exposed, the ball head 26 at the rear end of the indwelling thermometer 2 is inserted into the triangular clamping piece 16, at this time the indwelling thermometer 2 is installed in the implantation device 11, and the tester releases the rear sleeve 28, the outer spring 19 pushes the outer sleeve 18, so that the outer sleeve 18 again presses the L-shaped outer elastic sheet 17, so that each L-shaped outer elastic sheet 17 is in a state of inward contraction, at this time the front end of the L-shaped outer elastic sheet is pressed on the surface of the indwelling thermometer 2, the front end of the L-shaped outer elastic sheet 17 is in a roll-shaped or arc-shaped structure, which prevents the L-shaped outer elastic sheet 17 from scratching the indwelling thermometer 2; The health film sleeve 44 is sleeved on the outside of the output pipe 12 of the implantation device 11, and the open end of the health film sleeve 44 is tightly buckled on the output pipe 12; Press the switch of the implantation device 11, so that the motor 141 rotates forward, the screw sleeve 143 synchronously drives the push rod 15 to axially advance, the indwelling thermometer 2 carrying the health film sleeve 44 enters the cow anus, after the indwelling thermometer 2 is implanted into the cow anus, the rear end of the indwelling thermometer 2 falls off from the port of the guide pipe 13 of the implantation device 11 (i.e. off the port), and at the same time the front end of the L-shaped outer elastic sheet 17 is again buckled on the edge of the port of the guide pipe 13 under the elasticity of itself, blocking the port of the guide pipe 13; After the indwelling thermometer 2 off the port of the guide pipe 13, press the switch of the implantation device 11, so that the motor 141 reversely rotates, the screw sleeve 143 synchronously drives the push rod 15 to axially retreat, and pulls the core rod 25 backward (i.e. pulls the indwelling thermometer 2 backward), at this time the front end of the L-shaped outer elastic sheet 17 buckled on the edge of the port of the guide pipe 13 will block the indwelling thermometer 2, so that the indwelling thermometer 2 cannot enter the guide pipe 13, Figure 8As shown, since the rear end of the indwelling thermometer 2 is blocked and the indwelling thermometer 2 is pulled back by the push rod 15, the front end of the L-shaped outer spring 17 supports the push tube 31, so that the rear sliding sleeve 28 and the push tube 31 move axially forward on the shell 21 of the indwelling thermometer 2, compressing the air bag sleeve 29, and causing the air bag sleeve 29 to expand radially after being compressed axially. When the air bag sleeve 29 expands to the limit position, under the pulling action of the push rod 15, the triangular clamping piece 16 is separated from the ball head 26 (the triangular clamping piece 16 must have enough pulling force to be separated from the ball head 26), so that the implanting device 11 is separated from the indwelling thermometer 2, and the indwelling thermometer 2 is indwelled in the anus of the cow, so that the indwelling thermometer 2 detects the body temperature of the cow.

[0035] That is, during the pulling process of the push rod 15, the front end of the L-shaped outer spring 17 blocks the rear end of the push tube 31, so that the rear sliding sleeve 28 can move axially forward.

[0036] Since the rear end of the L-shaped inner spring 332 is elastic, when the rear sliding sleeve 28 and the push tube 31 move axially forward, the rear end of the L-shaped inner spring 332 can adaptively clamp the reverse tooth 32.

[0037] The purpose of the radial expansion of the air bag sleeve 29 is that after the indwelling thermometer 2 is implanted in the anus of the cow, it is easy to fall out of the anus, so that after the air bag sleeve 29 expands radially, the indwelling thermometer 2 can be clamped and supported on the inner wall of the anus of the cow for a period of time, because the detection of the body temperature needs to have a temperature recovery and stable process, the clamping and expansion of the air bag sleeve 29 of the device is realized through a linkage action, and the air bag sleeve 29 is expanded during the pulling process of the push rod 15, and is not simply inflated and expanded.

[0038] When the body temperature detection is completed and the indwelling thermometer 2 needs to be taken out of the anus of the cow, since the conical sliding sleeve 34 is still located in the elastic clamping sleeve 33, the rear end of the L-shaped inner spring 332 clamps the reverse tooth 32, so that the rear sliding sleeve 28 is in a locked state, and the air bag sleeve 29 is still supported on the inner wall of the anus of the cow. The detection personnel pulls out the conical sliding sleeve 34 from the elastic clamping sleeve 33 by a tool hook, the L-shaped inner spring 332 of the elastic clamping sleeve 33 automatically returns elastically to an inwardly contracted state, no longer outwardly clamping the reverse tooth 32, and the rear sliding sleeve 28 and the push tube 31 are unlocked. The rear sliding sleeve 28 is moved axially outwardly by the air bag sleeve 29, and the air bag sleeve 29 is reset. At this time, the indwelling thermometer 2 can be taken out of the anus of the cow.

[0039] After the indwelling thermometer 2 is taken out, it is disinfected and cleaned, and the conical sliding sleeve 34 is pushed into the elastic clamping sleeve 33 again, so that the L-shaped inner spring 332 clamps the reverse tooth 32 of the push tube 31. Next time, the indwelling thermometer 2 can be directly inserted into the implanting device 11, and when the rear sliding sleeve 28 and the push tube 31 move axially forward, the rear end of the L-shaped inner spring 332 can adaptively clamp the reverse tooth 32.

[0040] In this embodiment, a veterinary animal temperature detection device is described with the difference from the embodiment 1 as the center.

[0041] In this embodiment, as shown in Figure 7 A tool hook can be hooked in the hanging ring 341, and the tapered sliding sleeve 34 is pushed and pulled to move axially on the core rod 25.

[0042] The above description is only the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
