Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to a drug solution administration device that measures the weight of an animal and administers to the animal an amount of drug solution that matches the animal's weight and the type of drug solution, and particularly relates to a drug solution administration device. The present invention relates to an automatic drug administration device that automatically dispenses a drug into a syringe needle or syringe with a holder and administers it to an animal using a computer-controlled rotary pump.

[Prior art]

As shown in the first diagram, the conventional drug administration device measures the weight of an animal using an electronic balance 1, inputs the weight signal into a computer 2 to calculate the weight, prints the weight on a printer 3, and outputs the weight from the computer. 2, the body weight is converted to the amount of drug using the weight-medicine amount conversion coefficient (amount of drug in ml/kg of body weight) entered in advance, and the amount of drug is displayed on the display device 4, and the worker is displayed. Check the amount of the drug solution in the drug solution container 5.
This was a so-called manual device in which a medical solution 6 was dispensed into a syringe 7, and an operator injected the drug into the injection site of the animal using the syringe 7 containing the drug.

In such a conventional liquid drug administration device, the worker measures the weight of the animal, then fills the syringe 7 with an amount of drug 6 that matches the body weight and the type of drug, and then injects the animal into the syringe 7. The efficiency of drug dispensing and administration to animals is poor, and it takes an extremely long time to administer drug solutions to several hundred animals.

When a syringe 7 filled with a drug solution 6 is held in the hand and injected, the drug solution 6 often leaks from the tip of the syringe 7, causing an error in the amount of the injection solution and making it impossible to accurately inject the required amount of the drug solution 6.

In order to administer the drug solution 6 to a large number of animals, the syringe 7 must be inserted into the drug solution container 5 many times. Therefore, there are drawbacks such as the fact that the drug solution 6 in the drug solution container 5 is easily contaminated by bacteria adhering to the syringe 7.

[Purpose of the invention]

The present invention was made to solve the above-mentioned drawbacks, and instead of using a conventional syringe to dispense and inject (administer) the required amount of drug solution, a rotary pump controlled by a computer is used. By configuring the system so that the required amount of liquid medicine can be automatically dispensed into a liquid medicine dosing device such as a syringe needle with a holder or a syringe, and then injecting or injecting the same, the work efficiency of liquid medicine dispensing to the liquid medicine dosing device can be improved. It significantly improves the work efficiency of drug administration to animals, allows drug solution administration to a large number of animals in a short time, eliminates drug solution leakage, and accurately administers the required amount of drug solution. An object of the present invention is to provide a drug solution automatic administration device that can avoid contamination of a drug solution in a drug solution container with bacteria by eliminating the need to put in a drug solution container.

is a memory for storing those data, and the computer 14 and memory 15 are provided as necessary. The above calculation may be performed by the processor 10.

[Effect of the embodiment]

The operation will be explained in the above configuration. First, a key operation for cleaning the keyboard 9 is performed, and the character signal Kc output from this is decoded by the processor 10, which outputs a constant designation signal _S1 , and the memory 8 is processed by this signal _S1 . Outputs the specified constant signal _k1 . The processor 10 inputs and decodes this constant signal _k1 , and uses it as a pre-cleaning signal.
Output Sk ₁ . The roller pump 12 receives this signal.
Sk ₁ determines the predetermined number of rotations required for pre-washing, e.g. 10
As a result, the drug solution 6 is sucked from the drug solution container 5 and discharged from the injection needle 13, thereby washing and filling the inside of these and the tip of the injection needle 13 with the drug solution 6. Of course, this pre-washing is always performed when exchanging the chemical solution.

Next, the animal is placed on the electronic balance 1 and its weight W is measured, and the weight value is displayed as a digital value.
The output signal w of the electronic balance 1 is input to a processor 10 to read and store the weight W. On the other hand, the processor 10 decodes numerical and character key signals Km and Kc output by operating the keys on the keyboard 9.

From this, the processor 10 outputs a constant designation signal S ₂ , numerical values, and character signals m and c. Memory 8 is a signal
Outputs a constant signal k ₂ specified by S ₂ . The processor 10 reads this constant signal k ₂ and converts the measured weight W into the amount of drug solution Q (ml) = conversion constant K ₂ (ml/Kg) x
The measured body weight (Kg) is converted into a liquid medicine amount Q using a conversion formula, and from this, a liquid medicine quantity signal q and a liquid medicine discharge signal Sq corresponding to the liquid medicine quantity Q are output.

The display device 4 displays numerical values, character signals m, c,
Enter the weight signal w and drug volume signal q and enter the test name.
The animal number, sex, group, weight W, and amount of drug solution Q are displayed, and the printer 3 prints them out. Also, these data are stored in the memory 8 or external memory 11.
It can also be memorized and saved.

By inserting the injection needle 13 into a predetermined injection site of the animal and pressing the foot switch or the finger switch provided on the holder of the injection needle 13, the roller pump 12 inputs the drug solution discharge signal Sq, and thereby the animal's weight W and It rotates at a predetermined number of revolutions in order to discharge an amount Q of drug solution suitable for the type of drug solution, and injects the required amount Q of drug solution 6 into the injection site of the animal through the injection needle 13. If a syringe is used instead of the injection needle 13, the animal can be made to drink the required amount Q of the drug solution 6.

By repeating the above procedure, a predetermined number of animals can be injected with a drug solution in an amount appropriate for each animal's body weight, and can be made to drink it. When changing the type of chemical solution, it is necessary to change the amount of the chemical solution, but this can be handled by changing the conversion constant K ₂ in the memory 8 by operating keys on the keyboard 9.

When the drug solution has been administered to a predetermined number of animals, the computer 14 or processor 10 records the average weight, deviation amount, deviation range, etc. of the drug solution amount for each type of animal.
It is also possible to calculate this and store it in the memory 15, memory 8, or external memory 11, display it on the display device 4, or print it on the printer 3.

Note that when a roller pump is used as the rotary pump 12 as in the embodiment, the flow rate per revolution of the pump changes due to changes in the inner diameter and elasticity of the tube over time, so it is necessary to calibrate this. This flow rate calibration is performed as follows.

Place a 100ml container on electronic balance 1. Holding the injection needle 13 in your hand, turn the pump 12 at a predetermined number of revolutions.
For example, it rotates 100 revolutions, sucks in pure water with a specific gravity of 1.0, and discharges it from the injection needle 13 into the container above the balance 1. The flow rate per revolution of the pump is displayed on the display device 4, and the flow rate per revolution of the pump is calibrated to this flow rate by key operations on the keyboard 9.
With this calibration, pump 1 is controlled by the chemical liquid discharge signal Sq.
By changing the rotation speed of 2, a predetermined amount Q of drug solution can be administered.

When changing the rotation speed of the pump 12 during washing, change the washing constant K ₁ by operating the keys on the keyboard 9.
By changing the rotation speed of the pump 12 during pre-washing, it is possible to discharge an amount of chemical solution suitable for pre-washing and perform pre-washing.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the weight of the animal is measured using the electronic balance 1, the amount of drug solution Q that matches the body weight W and the type of drug solution is calculated by a computer, and the amount of drug solution Q is calculated by using a computer. By controlling the rotational speed of the rotary pump 12 for ejection, the required amount Q of the drug solution can be administered to the animal from the drug solution administering device 13, so that the efficiency of dispensing the drug solution to the dosing device 13 and the efficiency of the drug administration task are improved. It is possible to significantly improve drug administration to a large number of animals in a short period of time. In addition, since the drug is administered with the dosing device 13 inserted into the animal's injection site or inserted into the animal's mouth, the drug does not leak from the dosing device 13, and the required amount Q of drug can be administered accurately. , putting the dosing device 13 into the drug solution container 5,
Since the rotary pump 12 only sucks the medicinal liquid from the medicinal liquid container 5 and discharges it to the dosing device 13, there is no backflow, so there is no risk of the medicinal liquid 6 in the medicinal liquid container 5 being contaminated by bacteria.
