Description

Anorectal medicine applicator

Technical Field

The utility model relates to the field of medical instruments, in particular to a drug delivery device for anorectal medicine.

Background Art

Anorectal medicine is a department that specializes in the treatment of constipation, anal fissure, anal fistula, anal abscess, anal stenosis, anal papilla hypertrophy, perianal eczema, mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. The scope of its research is mainly on diseases of the organs at the end of the digestive system, which is between 8-12 cm from the anus to the rectum. However, the existing anorectal medicine applicators have the following problems during use:

Most of the existing anorectal drug delivery devices are in the form of syringes. The drug delivery device is inserted into the anus, and the injection rod is manually pushed by a person to drive the injection piston to squeeze the medicine in the drug delivery device outward, so that the medicine reaches the patient's anus or intestine through the remote hole. However, this manual direct push injection method makes it difficult for the person to control the pushing force, which can easily lead to pushing too fast and causing the medicine to quickly leak out and flow out of the person's body, causing waste. There is also no detailed capacity marking on the drug delivery device, and a part of the front end of the drug delivery device will be inserted into the patient's anus, making it difficult for medical staff to check the remaining amount of medicine in real time when injecting medicine into the patient's anus, and thus difficult to control the injection amount.

Utility Model Content

The utility model aims to provide a drug delivery device for anorectal medicine to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings and implementation modes:

As shown in Figures 1 to 4, an anorectal medication device comprises a medication tube 1, a shift ring 3 is connected to the upper side of the medication tube 1, a medication head 9 is threadedly connected to the bottom of the medication tube 1, and the medication head 9 is provided with a plurality of groups of medication outlet holes 10, a push rod 2 is threadedly connected to the medication tube 1, and the push rod 2 is rotatably connected to a piston 11, and the piston 11 abuts against the inner wall of the medication tube 1, and a gripping plate 4 is connected to the top of the push rod 2, and the gripping plate 4 is located outside the medication tube 1, and an air hole is provided on the upper side of the medication tube 1, and an arc plate 5 is slidably connected to the side wall of the medication tube 1, and the arc plate 5 is provided with scale lines 15, and the arc A slider 13 is connected to the top of the shaping plate 5, and the holding plate 4 is provided with a limiting ring groove 12. The slider 13 is slidably connected to the limiting ring groove 12, and the slider 13 can slide in a circle along the limiting groove. The slider 13 is connected to a rolling ball 14, and the rolling ball 14 is in conflict with the limiting ring groove 12. The dosing tube 1 is connected to an air bag 8, and the dosing tube 1 is connected to a micro air pump 6. The micro air pump 6 is connected to an air intake pipe 7, and the air intake pipe 7 is connected to the air bag 8. The longitudinal section of the air bag 8 is I-shaped; the structure and working principle of the micro air pump 6 are well known to practitioners in this field and will not be repeated here.

The specific implementation process is as follows:

Twisting the gripping plate 4 drives the push rod 2 to rotate, which in turn drives the piston 11 to move up and down along the dosing tube 1, connects the dosing head 9 to the dosing tube 1, rotates the gripping plate 4 to drive the push rod 2 and the piston 11 to move upward, and then sucks the medicine into the dosing tube 1, and the gripping plate 4 rotates and moves upward while pulling the arc plate 5 upward. Since the slider 13 is slidably connected with the limiting ring groove 12, the arc plate 5 moves upward as the gripping plate 4 rotates, and then the arc plate 5 is pulled out, and the upper port of the dosing tube 1 and the scale line 15 can be used to read the inhaled medicine volume at any time; when administering medicine, insert the dosing head 9 into the patient The threaded push rod 2 also avoids wasting medicine due to accidentally pushing the push rod 2 when inserting the dosing head 9. After the dosing head 9 is inserted into the corresponding position, the micro air pump 6 is started to inflate the air bag 8, and the anus is sealed by the air bag 8. The holding plate 4 is twisted to drive the piston 11 to move downward, and the medicine in the dosing tube 1 is pushed out from the medicine outlet 10 to complete the dosing. The arc plate 5 will also move downward with the downward movement of the holding plate 4, and the remaining amount of medicine in the dosing tube 1 can be read in time, so that the medical staff can accurately control the dosage and control the treatment process. After use, the drug dispenser can be taken out of the patient's affected area.

The present technical solution is provided with an arc plate 5 on the side wall of the drug delivery tube 1, and a scale line 15 is provided on the arc plate 5. The arc plate 5 will move with the movement of the push rod 2, so as to facilitate the medical staff to accurately control the injected medicine and the remaining medicine in the drug delivery tube 1, which is convenient to use and greatly improves the usability of the device. When the front end of the drug delivery device is inserted into the anus of the patient, accurate readings can also be made, and observation is convenient. The readings can be made by cooperating with the rear port of the drug delivery tube 1, which is convenient to use. The piston 11 is driven to move up and down by rotating the push rod 2, and then the medicine is delivered, which avoids the medical staff pushing the push rod to deliver the medicine in the direction of the push rod 2, resulting in too fast delivery and waste of liquid medicine, and further improves the stability of drug delivery. Qualitative; an airbag 8 is provided, and the airbag 8 is inflated to make it swell up, so as to seal the medication tube 1 and the anus, effectively preventing a large amount of liquid medicine from flowing out, improving the use efficiency, and solving the problem that the liquid medicine is easy to flow out of the patient's anus after being discharged; the medication head 9 is threadedly connected to the medication tube 1, and when the medication hole 10 of the medication head 9 is damaged during transportation, only the medication head 9 can be replaced to reduce waste; the longitudinal section of the airbag 8 is I-shaped, which ensures the comfort of the patient while achieving double leakage prevention and improving the sealing effect of the liquid medicine; the friction between the slider 13 and the side wall of the limiting ring groove 12 is reduced by the rolling ball 14, thereby improving the smoothness of the upward and downward movement of the arc plate 5.
