Medical infusion device

Abstract

The invention discloses a medical infusion device, which is characterized in that: the medical infusion device comprises an ultrasonic generator and a cavity body; the cavity body can tightly cling to the human skin and the side of the cavity body tightly clinging to the human skin is provided with a liquid permeation structure; the inside of the cavity body is provided with an ultrasonic transducer electrically connected with the ultrasonic generator through a wire; the cavity body is communicated with an infusion tube; the cavity body is provided with an air bleeder tube; the infusion tube is connected with a liquid medicine storage pump; the ultrasonic transducer is an ultrasonic piezoelectric ceramics chip; the medical infusion device also comprises a controller; the controller is connected with a computer; the liquid medicine storage pump and the ultrasonic generator are controlled by the controller; the inside of the liquid medicine outputted by the liquid medicine storage pump is provided with a pressure detection probe; and the pressure detection probe is connected with the controller. The medical infusion device has the advantages of carrying out infusion without using a needle to puncture the skin, having no wound, reducing pain of the patient and infection chance, increasing sensitivity of human cells to the medicine and improving curative effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to the technology of a medical drug delivery device. Background technique [0002] At present, there are usually intravenous injection and non-intravenous injection in the hospital to deliver medicinal liquid to the patient's body. Both of these methods require the needle to directly puncture the skin for infusion. Non-intravenous injection uses a syringe to suck the liquid medicine into the syringe, and then inserts the needle into the injection site such as people's buttocks or arms, and pushes the plunger of the syringe to inject the liquid medicine into the patient's body, because the needle is used to directly pierce the skin for infusion , so firstly it will increase the pain of the patient, secondly, if the disinfection is not in place, infection is easy to occur, and thirdly, when this method is used for injection, the human cells are less sensitive to the drug, so the curativ...

Problems solved by technology

Non-intravenous injection uses a syringe to suck the liquid medicine into the syringe, and then inserts the needle into the injection site such as people's buttocks or arms, and pushes the plunger of the syringe to inject the liquid medicine into the patient's body, because the needle is used to directly pierce the skin for infusion , so firstly it will increase the pain of the patient, secondly, if the disinfection is not in place, infection is easy to occur, and thirdly, when this method is used for injection, the human cells are less sensitive to the drug, so the curative effect is not obvious

Intravenous injection also has the disadvantages of non-intravenous injection, especially when the infusion needs to be infused for several days, the position of the needle needs to be changed, and at this time the needle must be re-inserted, which increases the pain of the patient, and for medical workers, increases the workload
