Description

rectal drug delivery device

technical field

The utility model relates to the technical field of medical appliances, in particular to a rectal drug delivery device.

Background technique

Modern medicine believes that the intestinal wall tissue of the rectum is a semipermeable membrane with selective absorption and excretion functions. The intestinal wall of infants is thin, which has the advantages of high permeability, large intestinal wall pores, low protein binding rate, and can increase the volume of drug distribution. Rectal administration replaces some unnecessary infusions. Traditional Chinese medicine, especially traditional Chinese medicine for clearing away heat and detoxification, replaces some unnecessary use of antibiotics. It is in line with the national policy of double restrictions on infusion and antibiotics, reduces infusion reactions and allergic reactions, and reduces the risk of clinical accidents. occur. Moreover, rectal administration reduces the clinical adverse reactions caused by the large particle size of traditional Chinese medicine injections and impurities entering the blood, which is conducive to the healthy development of the Chinese medicine industry in the motherland.

Traditionally, for rectal administration of infants and young children, a syringe is generally used to connect the administration tube, and the administration tube is inserted from the patient's anus into the rectum. However, the drug delivery tube is a flexible tube. After the drug delivery tube is inserted into the patient's anus, it will irritate the patient, especially infant patients, who will involuntarily contract the sphincter and pinch the drug delivery tube, making it difficult to continue inserting the drug delivery tube until the end of the patient's anus. In the rectum. And infants and young children are too old to relax the sphincter according to the instructions of the medical staff, which brings trouble to the work of rectal administration. Moreover, the dosage standard for infants and young children is relatively strict, and when medical personnel use a syringe to extract the medicinal solution, they generally cannot face up to the scale line on the syringe. The liquid level of the liquid is directly in line with the line of sight. Observe whether the amount of liquid medicine extracted is just right. If the amount is insufficient, it needs to be drawn again. If the amount is too large, the excess amount needs to be discharged, which causes waste and is troublesome.

Therefore, it is necessary to provide a new rectal drug delivery device to solve the above technical problems.
