The invention relates to the technical field of pharmaceutical preparations, and particularly discloses an anti-inflammatory analgesic indometacin long-acting suppository and a preparation method thereof.The suppository is composed of indometacin sustained-release microspheres and a modified fatty matrix; eudragit RS100 / RL100 is used as a compound framework of the sustained-release microspheres, the sustained-release microspheres are prepared through a spherocrystal granulation process, the modified fatty matrix is prepared from a mixed fatty glyceride compound matrix sustained-release aid, a three-dimensional suspending dispersant and the like through melting, pre-crystallization and high-speed homogenization processes, and the three-dimensional suspending dispersant contains modified nano silicon dioxide, glycerin monostearate and beewax. According to the invention, a microsphere-matrix dual controlled release system is constructed, so that burst release of drugs is eliminated, and long-acting stable release is realized; the microspheres are prevented from settling and agglomerating through a physical locking mechanism, and the storage stability of the preparation is improved by matching with a dual anti-oxidation system; meanwhile, rectal mucosa stimulation is reduced, the preparation process is simple, the quality is controllable, and the composition is suitable for anti-inflammation and analgesia of various diseases and has a wide clinical application prospect.

The invention relates to the technical field of medical instruments, in particular to a defecation assisting device which comprises a handheld push-pull part, a long handle, a push-pull rod and an outward shifting part, the long handle is a tubular rod, the push-pull rod slides in the long handle, the length of the push-pull rod is larger than that of the long handle, the outward shifting part is fixed to the upper end of the push-pull rod, and the handheld push-pull part is in threaded connection to the lower end of the push-pull rod. The disposable defecation assisting device solves the problem that when an existing disposable defecation assisting device is adopted to assist a patient in defecation, due to the fact that a long handle stretching into the rectum of the patient rubs with the rectum mucosa repeatedly, the rectum mucosa of the patient is damaged.

The application provides a ibuprofen suppository, a preparation method and application thereof, and belongs to the technical field of medicines. The application overcomes the defects of slow effect, easy leakage and low bioavailability of traditional suppositories. The suppository is a hollow suppository, which comprises a shell layer and content filled in a hollow cavity of the shell layer; the shell layer is composed of a water-soluble base and a bioadhesive material, the water-soluble base is a mixture of PEG 400 and PEG 1000 ; the content contains ibuprofen active ingredients and an absorption promoter; the content is in the form of a solid powder, when the suppository enters the rectum, the shell layer dissolves and adheres to the rectal mucosa, and the content is directly exposed to the rectal body fluid in the form of a solid powder and is quickly dissolved. The application is particularly suitable for children's antipyretic and analgesic drug preparation, and has the advantages of rapid effect, accurate dosage and good compliance.

The utility model discloses a kind of propelling devices using Kaiselu, set including propelling bracket, with the output pipe Kaiselu medicine bag and bowl type plug, the lower portion of the propelling bracket is equipped with guide pipe, the lower end of the guide pipe is equipped with spherical head, the output pipe middle part is bent into guide pipe, the bowl type plug is movably connected in the lower end port of spherical head, the Kaiselu medicine bag is exported Kaiselu medicine liquid by output pipe and spherical head, the upper portion of the propelling bracket is equipped with control component, and spherical head is entered anus by finger pressing down with the characteristics that it can avoid scratching anus or rectal mucosa accident, alleviate patient pain and improve medical care operation efficiency.

The invention discloses a constipation drug administration device, belongs to the technical field of constipation drug administration, and aims to solve the problems that when a constipation drug administration device is used for administration, a drug is easily blocked and adsorbed by excrement, ineffective loss of the drug is caused, and meanwhile the treatment efficiency is reduced. The constipation drug administration device comprises a liquid storage cylinder, and a liquid storage cavity is formed in the liquid storage cylinder; one side of the liquid storage cylinder communicates with a medicine injection assembly, a handrail assembly is arranged at one end of the liquid storage cylinder, a rotating cylinder is arranged at the other end of the liquid storage cylinder, a limiting insertion assembly is slidably arranged on the outer wall of the rotating cylinder, a spiral rotating assembly is fixedly connected to one end of the rotating cylinder, and a pushing assembly is slidably arranged in the liquid storage cylinder. According to the device, after the liquid outlet disc is attached to the rectal mucosa, the electromagnetic valve is conveniently switched, so that a medicament is uniformly sprayed out through the liquid outlet holes, the contact area of the medicament and the rectal mucosa is increased, the blocking of excrement is reduced, the drug effect absorption efficiency is improved, and then the invalid loss of the medicament is reduced.

This invention is titled "A Preservative and Bacterial Retention Swab and Method for Anorectal Sampling." It belongs to the field of medical testing technology. It primarily addresses the problem of insufficient sample volume and inaccurate test results, even false negatives, caused by operators using handheld cotton swabs for anorectal sampling and failure to promptly preserve and increase bacteria. Its main features are: an anal swab consisting of a swab handle and a swab head; the end of the swab head has a sampling hole and a tubular cavity; the sampling method is as follows: (1) Insert the anal swab into an anal swab tube containing a preservation solution or a bacterial growth solution; (2) The subject assumes a lateral or knee-chest position; (3) The operator manually or with an AI robotic arm removes the anal swab and gently inserts it into the anus, rotating or moving it back and forth at the rectal mucosa; (4) Then, the anal swab is slowly removed and directly placed into an anal swab tube for sealing, preserving or culturing the sample. This invention mainly collects samples from the anus and rectum and preserves and increases bacteria for the detection of microorganisms and parasites in the body.

This utility model relates to the field of body temperature measurement technology and discloses an electronic rectal thermometer for newborns. It includes a soft grip for medical personnel to hold, with a soft front end fixedly connected to one end. A blunt tip for adhering to the rectal mucosa is fixedly connected to the end of the soft front end away from the soft grip. A battery pack for providing power is located on the side of the soft grip away from the soft front end, and the battery pack and the soft grip are detachable. Medical personnel hold the soft grip and gently insert the blunt tip into the newborn's rectum. The soft front end naturally bends with the tissue shape. The battery pack provides power during this process. A touch switch recognizes the touch action through a capacitive sensing mechanism. Upon triggering, an electrical signal is generated and transmitted to the signal controller via a control connection line and a reinforced connector, initiating the device's signal transmission and processing flow. This avoids the problem of poor contact with mechanical buttons and ensures the reliability of the switch control.
