Full automatic mix push injection pump

Abstract

The invention relates to a full automatic mix push injection pump, which comprises a main controller, and also comprises a medicine push injection device and a mix emulsifying device, wherein the medicine push injection apparatus comprises a support, a transmission device and at least two injectors; a pipe body of each of the injectors is fixed and mounted on the support; a group of slide grooves are formed on the support; a slide regulating stopper is mounted in each of the slide grooves; and the transmission device comprises a power mechanism and a push plate connected to the power mechanism. According to the invention, the full automatic mix injection pump is capable of avoiding various defects of the original method in the existing technology; the disadvantages of manually mixing and pushing are solved; through the ultrasonic emulsification technology, the ultrasonic power can be regulated to the best emulsification effect and unsafe and unstable emulsification during the manually mixing process is avoided; the speed of the injection pump is regulated by a computer, thus stable injection with constant speed is realized and the disadvantages of injecting too fast or too slow are avoided; the waste of medicine and the pollution to the medicine due to repeatedly match up medicine are avoided; and at the same time, the time of operation is reduced.

Description

technical field [0001] The invention relates to a fully automatic mixing injection pump, which belongs to the field of medical equipment. Background technique [0002] In the process of hepatic arterial interventional chemoembolization for primary liver cancer, a very important step is to mix iodized oil and water-soluble chemotherapeutic drugs to form an oil-in-water or water-in-oil emulsion to achieve embolization of lesions with iodized oil. Chemotherapeutic drugs reside in the lesion and continue to kill tumor cells. The current common method is to repeatedly mix iodized oil and water-soluble drugs by mechanical means to achieve the purpose of forming an emulsion, and manually inject the mixed drugs into tumor blood vessels. There are following defectives in this original method: 1. the method for mechanical mixing, is subject to operator's individual influence factor bigger, as the stability of emulsified iodized oil such as how many times of operator's mixing, the siz...

AI Technical Summary

Problems solved by technology

There are following defectives in this original method: 1. the method for mechanical mixing, is subject to operator's individual influence factor bigger, as the stability of emulsified iodized oil such as how many times of operator's mixing, the size of mixing force, the length of mixing time etc. Sexuality is greatly affected, and at the same time, the speed of injection after emulsification also affects the stability of emulsified lipiodol, which has a greater impact on the therapeutic effect

2. The leakage of chemotherapy drugs and iodized oil will be caused during the mechanical mixing process. Sometimes the syringe will be broken during the mixing process, resulting in waste of drugs. At the same time, chemotherapy drugs will have toxic effects on the operator, such as chemotherapy drugs. Splash into eyes or stain skin

3. After the iodized oil is mixed, the clinician needs to manually inject the emulsified iodized oil into the patient's body. During this process, the clinician needs to observe repeatedly under radiation to confirm that the iodized oil enters the tumor blood vessel without reflux or abnormality. embolism, the clinician needs to be exposed to radiation for a long time, which will cause personal injury to the clinician

Based on this, in order to avoid radiation damage to the body, some doctors speed up the injection or reduce the dosage, which will affect the therapeutic effect

4. During each injection of iodized oil emulsion, according to the size of the lesion and the patient’s response to treatment, the nurse needs to dispense the medicine several times. After the nurse dispenses the medicine, the doctor manually mixes it again, which not only increases the operation time, but also increases the chance of infection

5. During the operation, if the prepared emulsified iodized oil is injected, if it is found that the tumor embolism is complete or reflux occurs, often this part of the drug can no longer be injected, and the rest of the drug will be wasted

[0003] After retrieval, the invention patent with the patent number of 2012104386384 discloses a syringe pump, but the disclosed content of the patented technical solution is only suitable for direct injection of a drug or a drug that has been mixed and emulsified, and there are still many shortcomings. Solve the above-mentioned technical problems
