Description

Rectum injection drug feeder

Technical Field

The utility model relates to the field of medical instruments, in particular to a rectal injection drug feeder.

Background

When in rectal administration, the medicine is delivered into the intestinal canal through anus, absorbed by the rectal mucosa and enters the large circulation, and the medicine effect is exerted to treat systemic or local diseases.

For patients who use rectal suppositories in clinic to achieve the aim of treatment, medical staff usually plug the suppository drugs into anus by fingers, and the mode is operated completely by feeling, which can cause inaccurate dosing, increase pain of the patients, bring inconvenience to the medical staff and other problems.

Clinical application proves that the clinical effects of rectal administration and intravenous administration are not obvious, the utilization rate of the rectal administration is better than that of oral administration, and the rectal administration can simultaneously apply Chinese and western medicines, thereby reducing the occurrence of side effects and enhancing the treatment effect. Rectal administration is therefore often used in the clinic.

For patients who use rectal suppositories in clinic to achieve the treatment purpose, medical staff usually plug solid medicines of the suppositories into anus by fingers, errors can be generated on the positions of the medicines, and particularly under the condition of higher temperature, the suppositories are easy to melt and soften, the suppositories are difficult to be placed into anus, and the administration dosage of the medical staff is inaccurate, so that inconvenience is brought to the patients and the medical staff.

Preferably, the expander 1 comprises an expander 101, a grip 102, a lamp 103, a lamp groove 104, a mounting hole 105, an anti-slip groove 106 and a switch 107; the expansion cylinder 101 and the grip 102 are integrally formed; the lamp groove 104 is arranged in the inner side surface of the expansion cylinder 101, and the bottom surface is provided with a mounting hole 105 and an anti-skid groove 106; the lamp 103 is placed in the lamp groove 104; the switch 107 is provided on the lamp 103. The materials of the expansion cylinder 101 and the grip 102 are transparent plastics, and the expansion cylinder 101 is conical; the lamp 103 uses a button cell as a power supply, and the expansion cylinder 101 is made of transparent plastic, so that when the lamp 103 is turned on, the expansion cylinder 101 is in a light emitting state due to refraction of light.

Preferably, the expander 1 and the injector 2 can be detached, so that the subsequent cleaning of the device is facilitated; the injector head 202 of the injector 2 may be selected to be of a suitable length and size depending on the site of the patient to be dosed; in the use process, the passenger flow of the dilator 1 is at the anorectal position of the patient, and medical staff can exchange the injection head 202 or inject the medicament for multiple times according to the injury of the patient.

Preferably, the front end of the dilator 1 is provided with an opening, so that the part of the anorectal area of the patient, which needs to be loaded with medicine, can be extruded into the dilator 1, and then, medical staff can more accurately and effectively load medicine on the affected part.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model has simple structure and reasonable design; the accurate control of the medicine feeding depth can be achieved, and the problems of unsanitary medicine feeding, unsanitary medicine feeding and the like are solved; the device can be used for feeding medicine aiming at the deep part of the anorectal of a patient, and all parts in the device can be detached, so that the subsequent cleaning and disinfection of the device are facilitated; the device can freely enter and exit, and the depth of the entering and exiting can be controlled; the front end of the device is provided with an opening, the part of the anorectal of the patient needing to be loaded with medicine can be extruded into the device, and then medical staff can accurately and effectively load medicine on the part of the affected side.
