Description

Technical Field

[0001] The utility model relates to the technical field of rectal drug administration auxiliary equipment, in particular to a suppository extruding device with adjustable drug administration depth. Technical Background

[0002] Rectal administration refers to a method of delivering drugs into the intestine through the anus, where they are quickly absorbed by the rectal mucosa and enter the general circulation to treat systemic or local diseases. There are three main methods of rectal administration: retention enema, rectal drip, and suppository insertion.

[0003] The current method of inserting suppositories is assisted by a rectal drug delivery device. The rectal drug delivery device is generally a disposable device similar to a needle tube. The outside of the drug delivery device is provided with a scale. The patient uses the scale on the outside of the drug delivery device to judge the depth and position of drug delivery. This type of rectal drug delivery device has the following defects: although the outside of the drug delivery device is provided with a scale, the insertion depth of the drug delivery device cannot be fixed, and the suppository may not reach the ideal position in the rectum or be inserted too deep, thereby affecting the efficacy; the rectal drug delivery device is a disposable device, and each drug delivery device only contains a single dose. The rectal drug delivery device will be discarded after use. For patients with a long course of treatment, a disposable rectal drug delivery device will cause a large amount of medical waste to be generated.

[0004] In order to solve the above technical problems, a Chinese utility model patent with application number 201920619319.0 announced a rectal drug delivery device, which is characterized by: comprising a reusable drug pusher and a disposable drug loader, the drug loader is used to hold suppositories, and the drug pusher is used to push the suppositories inside the drug loader into the rectum; a baffle is installed on the outside of the mounting end of the drug loader, the diameter of the baffle is greater than the diameter of the anus, the length of the drug loader is the insertion depth in the anus, and the baffle is used to fix the position of the insertion depth; the insertion depth of the rectal drug delivery device is fixed, so that the suppository can reach the ideal position in the rectum to achieve a therapeutic effect; the rectal drug delivery device is a partially disposable drug delivery auxiliary device, which can be partially discarded after the drug delivery is completed, and the other parts can be reused after disinfection to avoid the generation of a large amount of medical waste.

[0005] However, the above-mentioned prior art still has the following technical problems: the length of the medicine charger is the insertion depth in the anus, but the length of a single medicine charger is fixed. When administering medicine to sites with different depths in the anus, it is necessary to replace medicine chargers of different lengths for rectal administration, and the insertion depth in the anus cannot be adjusted on a single medicine charger. A single rectal medicine charger is less versatile for suppositories with different anal administration depths and patients requiring different anal administration depths. Utility Model Content

[0025] Furthermore, the clamping cover 122 is also provided with a finger gripping groove 1221 to enable medical staff to hold it more comfortably.

[0026] For further information, see Figure 5 The suppository installation lubrication mechanism 11 comprises a suppository installation head 111, a lubricant extrusion net 112 and a lubricant storage bin 113; the suppository installation head 111 is a cylinder with a through hole in the center thereof for placing suppositories, and a protective film clamping protrusion 1111 and a connecting internal thread 1112 are arranged on one side of the suppository installation head 111; the lubricant extrusion net 112 is arranged on the inner wall of the through hole of the suppository installation head 111; the lubricant storage bin 113 is arranged on the suppository extrusion head 111, which is an annular groove and is connected to the outside; the lubricant extrusion net is connected to the lubricant storage bin 113; the connecting internal thread 1112 on the suppository installation head 111 is matched and connected with the connecting external thread 1213 of the extrusion barrel 121; The lubricant extrusion mechanism 11 can squeeze the lubricant in the lubricant storage bin 113 through the lubricant extrusion net 112 and apply it on the suppository to play a lubricating role and reduce the patient's discomfort.
