Description

Technical Field

[0001] The invention relates to a veterinary mercury-free thermometer and a use method thereof, belonging to the technical field of temperature measurement. Background Art

[0002] Thermometers are roughly divided into veterinary thermometers and human thermometers according to the different measurement objects. Veterinary thermometers are different from human thermometers in the measurement site and measurement method. In clinical practice, veterinary thermometers are usually used to measure the temperature in the rectum of animals. Veterinary thermometers are divided into electronic thermometers and traditional mercury stick thermometers. The temperature accuracy of electronic thermometers is unstable, the precision is poor, the price is a bit high, and it is not easy to use after using it for a long time. In addition, electronic thermometers are calibrated with traditional mercury stick thermometers, but once traditional mercury stick thermometers are accidentally broken during use, the mercury stick thermometers will be damaged. Silver will evaporate, and mercury has particularly good adsorption properties. Mercury vapor is easily adsorbed by walls and clothes, becoming a source of continuous air pollution. Although inhaling a small amount of it will not cause much harm to the body, long-term inhalation of large amounts will cause mercury poisoning; and the existing traditional veterinary thermometers are not applicable and are not suitable for all animals. When measuring large animals, they are easy to fall off from the anus, thus requiring replacement of a slightly larger thermometer. Therefore, it is urgent to develop and produce a mercury-free thermometer that can replace traditional mercury veterinary thermometers on a large scale and has greater universality.

The scale lines on the scale card 5 correspond to the actual temperature lines. A protective sleeve 6 is wrapped on the outer surface of the glass tube body 2. The side wall thickness of the protective sleeve 6 gradually increases from the front end to the rear end. The protective sleeve 6 is provided with openings 7 on both sides of the glass tube body 2 corresponding to the scale card 5, and semicircular protrusions 8 are irregularly arranged on the upper and lower surfaces of the protective sleeve 6; the placement of the scale card 5 eliminates the need for acid etching or silk-screening of scales in the thermometer manufacturing process. At the same time, the semicircular protrusions 8 on the protective sleeve 6 can increase the friction between the thermometer and the animal's anus without causing damage to the animal's anus, thereby preventing the protective sleeve 6 from falling off during measurement and affecting the measurement result.

[0033] In this embodiment, the protective cover 6 is made of transparent silica gel; silica gel can prevent the thermometer from causing harm to the animal when it is inserted into the anus of the animal.

[0034] In this embodiment, an inflation device 9 is fixedly installed at the rear end of the glass tube body 2. The inflation device 9 is a cylindrical structure. A piston plate 10 is slidingly and sealingly connected inside the inflation device 9. A push-pull rod 11 is fixedly connected in the middle of the piston plate 10. A pull ring 12 is arranged at the tail end of the push-pull rod 11. The pull ring 12 is tied to one end of a thin rope, and the other end of the thin rope is tied to a clip. Two air intake check valves 13 are respectively arranged on the upper and lower surfaces of the piston plate 10. An inflatable airbag 14 is wrapped on the outer surface of the rear end of the glass tube body 2. The inflatable airbag 14 is connected to the inflation device 9 through an air inlet duct 15 arranged on the bottom side of the inflatable device 9. An air outlet check valve 16 is arranged on the air inlet duct 15, and a small air release valve 17 is arranged on the outer surface of the inflatable airbag 14.

[0035] In this embodiment, the inflatable airbag 14 expands longitudinally after being inflated.

[0036] In this embodiment, the thermometer also includes a storage box 18, with soft foam placed at the bottom of the storage box 18, a small gap the size of the thermometer is opened in the middle of the soft foam, and an installation cover 19 is slidably sleeved on the upper part of the storage box 18, and friction grooves 20 are provided on both sides of the installation cover 19.

[0037] A method for using a veterinary mercury-free thermometer comprises the following steps:

[0038] Step 1: Open the storage box 18, take out the thermometer, hold the rear end of the thermometer, and use a little force to swing the temperature-sensitive liquid column in the capillary hole 3 to below the 35-degree scale line;

[0039] Step 2: Disinfect the outer surface of the thermometer with alcohol and then apply lubricating oil. Clamp the hair on the tail base with the clip tied with a thin rope. Grab the animal's tail, then hold the thermometer and slowly insert it into the anus slightly in the dorsal direction.

[0040] Step 3: For larger animals, all parts of the thermometer except the inflation device 9 can be slowly inserted into the anus, and then the left hand holds the inflation device 9, and the right hand slowly pushes and pulls the push-pull rod 11 back and forth to slowly inflate the inflation airbag 14 until it fits tightly against the inner wall of the animal's anus, and the thermometer is left standing for 3-5 minutes;

[0041] Step 4: slowly take out the thermometer, hold the far end of the thermometer with your right hand in a horizontal direction and level with your eyes, make your eyes look directly at the temperature-sensitive liquid column, read the measured value, and then pull out the small deflation valve 17 to discharge the gas in the inflatable airbag 14;

[0042] Step 5: Use an alcohol cotton ball to disinfect and clean the thermometer, and then put it back into the storage box 18.

[0043] The mercury-free thermometer for animals described in this embodiment uses gallium-indium-tin alloy instead of mercury as the temperature-sensitive liquid. A scale card 5 is placed in the axial direction inside the glass tube body 2. The scale lines on the scale card 5 range from 35 degrees to 43 degrees. The placement of the scale card 5 eliminates the need for acid etching or silk-screening scales in the thermometer manufacturing process. A curved neck tube 4 is provided at a position where the capillary pore 3 is close to the temperature-sensitive bulb 1. The flow area of ​​the curved neck tube 4 is smaller than the flow area of ​​the capillary pore 3. After the thermometer is pulled out of the animal's body, the external temperature is low, and the temperature-sensitive liquid in the temperature-sensitive bulb 1 contracts when it is cooled and is disconnected in the narrow curved neck tube 4. The curved neck tube 4 prevents the temperature-sensitive liquid that has risen into the capillary pore 3 from returning, and is used to record the highest measured temperature. The outer surface of the glass tube body 2 is wrapped with a protective sleeve 6, and the thickness of the side wall of the protective sleeve 6 gradually increases from the front end to the rear end. The protective sleeve 6 is provided with openings 7 on both sides of the glass tube body 2 corresponding to the scale card 5. Semicircular convex points 8 are irregularly arranged on the upper and lower surfaces of the protective sleeve 6. When measuring the rectal temperature of the animal, since the protective sleeve 6 is made of transparent silicone, the semicircular convex points 8 on the protective sleeve 6 can increase the friction between the thermometer and the animal's anus without causing damage to the animal's anus, so as to prevent the thermometer from falling off during measurement and affecting the measurement result. The opening 7 provided on the protective sleeve 6 is used to check the measured temperature; when measuring the body temperature of large animals, in order to prevent the thermometer from falling off, an inflation device 9 is fixedly installed at the rear end of the glass tube body 2. A piston sheet 10 is slidably and sealably connected inside the inflatable device 9, a push-pull rod 11 is fixedly connected in the middle of the piston sheet 10, a pull ring 12 is arranged at the tail end of the push-pull rod 11, the pull ring 12 is tied to one end of a thin rope, and the other end of the thin rope is tied to a clip. By tying a rope with a clip on the pull ring 12, it can prevent the thermometer from falling off and being damaged on the ground, and it can also prevent the thermometer from being trapped in the rectum of the animal and being difficult to take out. Two air inlet check valves 13 are respectively arranged on the upper and lower surfaces of the piston sheet 10, and an inflatable airbag 14 is wrapped on the outer surface of the tail of the glass tube body 2. The inflatable airbag 14 is connected to the inflatable device 9 through an air inlet 15 arranged on the bottom side of the inflatable device 9, and an air outlet check valve 16 is arranged on the air inlet 15. When the push-pull rod 1 When the push-pull rod 11 is pulled back, a negative pressure state is formed in the inflatable device 9. At this time, the two air inlet check valves 13 are opened inwardly to inflate under the pressure difference of the external atmospheric pressure. Then, when the push-pull rod 11 is pushed forward, the two air inlet check valves 13 are closed, and the piston plate 10 squeezes the air in the inflatable device 9 into a high-pressure state. The high pressure causes the air outlet check valve 16 to open and discharge the gas into the inflatable airbag 14. In this way, the push-pull rod 11 is pushed and pulled back and forth to inflate the inflatable airbag 14. The inflated inflatable airbag 14 can fix the thermometer without hurting the animal's anus, preventing the thermometer from falling off and causing inaccurate measurement results. A small air release valve 17 is provided on the outer surface of the inflatable airbag 14. When the thermometer is pulled out, the valve is opened to discharge the gas and wait for the next use.

[0044] A method for using a mercury-free thermometer for animals, first open a storage box 18, take out the thermometer, hold the rear end of the thermometer, and use a little force to swing the temperature-sensitive liquid column in the capillary hole 3 to below the 35-degree scale line, first disinfect the outer surface of the thermometer with alcohol and then apply lubricating oil, clamp the hair on the tail root of the animal with a clip tied with a thin rope, grab the tail, and then hold the thermometer, slightly tilted to the dorsal direction and slowly insert it into the anus. For larger animals, the entire part of the thermometer except the inflation device 9 can be removed. Insert the thermometer into the anus slowly, then hold the inflation device 9 with the left hand, and slowly push and pull the push-pull rod 11 back and forth with the right hand to slowly inflate the inflatable airbag 14 until it is tightly fitted with the inner wall of the animal's anus. Leave the thermometer for 3-5 minutes, then slowly take out the thermometer, hold the distal end of the thermometer with the right hand horizontally and at eye level, so that the eyes look directly at the temperature-sensitive liquid column, read the measured value, and then unplug the small air release valve 17 to discharge the gas in the inflatable airbag 14, disinfect and wipe the thermometer with an alcohol cotton ball, and put it back into the storage box 18.

[0045] The present invention adopts gallium indium tin alloy as the temperature-sensing liquid of the thermometer, thereby increasing the safety of the thermometer during use; a protective cover made of transparent silicone wrapped on the outer surface of the thermometer can increase the friction between the thermometer and the animal's anus without harming the animal, thereby preventing the thermometer from falling off from the animal's anus; an inflatable airbag is wrapped on the outer surface of the tail of the thermometer, and the inflatable airbag can be used in conjunction with an inflating device to expand the inflatable airbag longitudinally, which is suitable for anal temperature measurement of large animals and reduces the possibility of the thermometer falling off from the anus.
