The invention discloses a clinical postoperative analgesic and hemostatic device for anorectal surgery, and relates to the field of medical equipment. The device includes an injection bottle and a base, a lubricating mechanism is installed on the side wall of the upper end of the injection bottle, a sealing mechanism is installed at the side wall of the injection bottle, and a pushing mechanism passes through the side wall of the lower end of the injection bottle; and positioning blocks are fixedly connected to the inner side wall of the base, the side wall of the upper end of each positioningblock abuts against the side wall of the lower end of the injection bottle, a moving mechanism is installed on the inner side wall of the base, and the side wall of the upper end of the moving mechanism abuts against the side wall of the lower end of the injection bottle. Through the cooperation among the lubricating mechanism, the sealing mechanism, the pushing mechanism and the positioning blocks, in the process of injecting a medicine into a patient, due to the squeeze between an anus and a soft capsule, a lubricating fluid is squeezed out, so that the anus is lubricated, and the conditionthat pain is caused to the patient during direct insertion of the device into the anus is avoided.

The invention provides a ropivacaine hydrochloride sodium chloride injection and a preparation method thereof. The method comprises the process steps of: burdening, carbon adsorption, rough filtering, fine filtering, filling, sterilizing, lamp detecting, packing and the like. The prepared ropivacaine hydrochloride sodium chloride injection has a definite medicinal effect and high safety; the test result of each index in a stability test is accordant with specifications, and the defects of the requirement of repeated injection, inconvenience in using, easiness in increasing secondary pollution by freeze-dried powder and the like existing in a ropivacaine water injection are overcome; the ropivacaine hydrochloride sodium chloride injection is particularly suitable for a patient using an analgesia pump; during use in a large volume, an instant stable concentration is kept for a medicinal liquid, so that a remarkable postoperative analgesic effect is achieved, and the requirement of an opioid medicament is remarkably lowered; and moreover, the effect can be enhanced rapidly by administrating in a self-pressing way.

The invention belongs to the field of medical supplies and provides an anesthesia dressing and a preparation method thereof. The anesthesia dressing includes an anesthesia layer and a heating layer, the anesthesia layer is a gel containing anesthesia drugs and anesthesia drug slow-release microspheres, and the heating layer sequentially includes an isolation film adjacent to the anesthesia layer, a self-heating material and a gas-permeable film . The anesthesia dressing provided by the present invention is simple and convenient to use, easy to apply, and does not need to be cleaned after use; the anesthesia dressing uses anesthesia drug and anesthesia drug slow-release microcapsules to prolong the duration of the anesthesia effect, and uses heating to shorten the duration of the anesthesia effect. The onset time of anesthetic drugs makes the anesthetic dressing have the advantages of fast onset of anesthesia effect and long duration. It can be widely used in various operations that require surface anesthesia, and is also convenient for postoperative analgesia and various intractable pains. Treatment.

The invention belongs to the field of the anorectal department, and particularly relates to a clinical postoperative analgesia and hemostasis device in the anorectal department. For the problems thatan existing single chip microcomputer is exposed to easily cause electric leakage, and heating of medicine liquid in a medicine chest is not uniform, the following scheme is proposed that the device comprises a medicine chest, wherein one side of the medicine chest is provided with a booster pump, one side of the booster pump is provided with a threaded hose, one end of the threaded hose is provided with a ball bag, the inner wall of the bottom side of the medicine chest is provided with a heater, the side, away from the booster pump, of the medicine chest is provided with a single chip microcomputer, the inner wall of the top side of the medicine chest is provided with a rotating hole, and the top side of the medicine chest is fixedly provided with a motor. The clinical postoperative analgesia and hemostasis device in the anorectal department has the advantages that a protection box is arranged to effectively avoid the problem of electric leakage caused by the fact that the medicine liquid leaks on the single chip microcomputer, and eliminate potential safety hazards; stirring rods drive agitating blades to stir the medicine liquid in the medicine chest all-directionally, so thatthe medicine liquid is heated more uniformly, thereby avoiding the discomfort of a patient caused by the too large temperature difference during drug administration.
