Muscle indwelling needle

Abstract

The invention relates to a muscle indwelling needle which comprises a needle part. The needle part comprises a needle base, a needle head cover and a guide needle; the needle base comprises a soft mat used for being attached to a human body, multiple indwelling hoses are arranged at the front end of the soft mat, the needle base and the needle head cover are a bonding rigid body, and a cavity gap capable of containing injection fluid is formed between the needle base and the needle head cover; the guide needle is provided with single hard needles or multi-joint hard needles which correspond to and are similar to the number, shape and distribution of the indwelling hoses, the hard needles penetrate through the needle head cover and are inserted into the indwelling hoses, and the tail tips of the hard needles extend out of the indwelling hoses; the guide needle is an independent single body and is connected with the bonding rigid body to form a puncture function body. The technical operation of the muscle indwelling needle comprises two sequential steps of indwelling puncture and medicine injection, when indwelling puncture is conducted, the hard needles and indwelling hoses are together inserted into human muscles, and after the guide needle is pulled out, the assembly of the base and the needle head cover is left outside the human skin; when medicine injection is conducted, a specified or ordinary syringe is adopted to be pierced into the soft mat on the upper surface of the head cover, and liquid medicine enters the human muscle through the indwelling hoses by being driven by the pressure.

Description

technical field [0001] The invention relates to an indwelling needle for intramuscular injection, which belongs to the field of indwelling medical technology for intramuscular injection. Background technique [0002] In the existing medical technology, indwelling needles have been used for intravenous injection. At present, there are no indwelling needles for intramuscular injection. The main reason is that the hard foreign objects indwelling in the human host cause irritation pain and inconvenience. [0003] Although the drug absorption of intramuscular injection is more reliable than that of oral administration, its maintenance of drug concentration is more stable than that of intravenous injection, and its technical operation is simpler than that of intravenous injection, the current intramuscular injection has the following major defects: repeated injections are painful; It must be carried out on a specific occasion in the hospital; the injection of drugs is concentrated...

Problems solved by technology

[0002] In the existing medical technology, indwelling needles have been used for intravenous injection. At present, there is no indwelling needle for intramuscular injection. The main reason is that the hard foreign objects indwelling in the human host cause irritation and pain and inconvenient activities.

[0003] Although the drug absorption of intramuscular injection is more reliable than that of oral administration, its maintenance of drug concentration is more stable than that of intravenous injection, and its technical operation is simpler than that of intravenous injection, the current intramuscular injection has the following major defects: repeated injections are painful; It must be carried out on a specific occasion in the hospital; the injection of drugs is concentrated, forming drug irritation and causing sequelae; large doses of drugs cannot be used; suitable body parts for injection are limited
