Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an intrarectal pressurized medicine dressing device based on dynamic airbag support. Background Art
[0002] Under physiological conditions, the rectal cavity is in a closed state. At this time, the rectal mucosa is not smooth and has wrinkles, while the rectal wrinkles often disappear in a filled state. Rectal mucosal lesions, such as viral warts and submucosal latent HPVs infection, are often combined with photodynamic therapy. Before treatment, the photosensitizer must be applied locally with a wet compress for 3 hours before light therapy.
[0003] Before the current photodynamic therapy for rectal viral warts, the prepared photosensitizer needs to be soaked in the required gauze and then inserted into the rectum as a whole. This method has the following problems: 1. When the gauze is inserted for wet compress, the rectal mucosa is not easy to fully contact with the photosensitizer, and the photodynamic therapy effect cannot be guaranteed; 2. The photosensitizer is expensive, and a large amount of medicine is required to completely soak the required gauze. In fact, only the gauze that contacts the rectal mucosa at the periphery actually plays the role of wet compress, and the photosensitizer in the center of the gauze cannot contact the rectal mucosa, resulting in a great waste of photosensitizer; 3. No matter what position the patient adopts for applying the medicine, due to the effect of gravity, the rectal mucosa part of the anti-gravity wet compress can only absorb less medicine, or even cannot absorb any medicine, which has a certain impact on the photodynamic therapy effect. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] The basic technical solution provided by the utility model is: an intrarectal pressurized dressing device based on dynamic airbag support, comprising a mounting seat and an adjusting column, the mounting seat is rotatably connected to the adjusting column, the adjusting column is rotatably connected to two groups of mounting sleeves, the two groups of mounting sleeves are rotatably connected to two groups of connecting rods, the connecting rods are rotatably connected to a support plate, the mounting seat is fixedly connected to the adjusting sleeve through a connecting column, the adjusting sleeve is threadedly connected to the adjusting column, the adjusting sleeve is connected to the support plate through the connecting rod, the support plate is slidably connected to a pressure plate, the support plate is provided with a pressure measuring component, the pressure plate is fixedly connected to an airbag, and the airbag is detachably connected to a dressing layer.

The adjusting sleeve and the adjusting column can be controlled to move relative to each other through threaded cooperation. The adjusting sleeve controls the support plate to move away from or close to the adjusting column through a connecting rod, so that the support plate drives the airbag to move outward or inward through the pressure plate. The pressure measuring assembly is used to measure the pressure exerted by the pressure plate on the support plate.
[0008] The beneficial effects of the basic technical solution are: before the device is inserted into the patient's rectum, the gas inside the airbag is emptied to reduce its volume, and the airbag is placed close to the adjusting column by rotating the adjusting column, thereby facilitating the insertion of the device into the rectum and reducing the difficulty of operation for medical staff; when the device is inserted into the designated position, the airbag is inflated to increase its volume, and the airbag is placed away from the adjusting column by rotating the adjusting column, and the pressure exerted by the device on the rectum can be accurately controlled by the pressure measuring component, thereby achieving the purpose of complete disappearance of rectal folds and full stretching and exposure of the rectal mucosa, so that the dressing layer is in full contact with the rectal mucosa, thereby improving the effectiveness of the rectal mucosa in absorbing the photosensitizer, thereby reducing the amount of photosensitizer used and improving the absorption rate of the mucosa.
[0009] Preferably, the pressure measurement assembly comprises a pressure sensor, and the pressure sensor is located between the support plate and the pressure plate.

[0017] Preferably, the airbag is fixedly connected with an injection tube connected to the first injection groove, and a one-way valve is provided at the connecting end of the injection tube and the airbag.
[0018] Through the above arrangement, the photosensitizer is injected into the first injection tank through the injection pipe, and the function of the one-way valve is to block the photosensitizer in the first injection tank and the second injection tank to prevent it from flowing back into the injection pipe, thereby ensuring the effectiveness of the photosensitizer.

[0020] Through the above arrangement, when the photosensitizer of the dressing layer needs to be supplemented, the photosensitizer is injected into the injection tube through the syringe, which not only reduces the waste of photosensitizer but also ensures the effectiveness of photodynamic therapy. The one-way valve 2 prevents the gas from flowing out of the ventilation hole, and the one-way valve 3 prevents the liquid and gas in the part of the injection tube located at the left end of the ventilation hole from flowing to the liquid inlet hole. By repeatedly pumping and pressing the piston of the empty syringe (the syringe without photosensitizer), the residual photosensitizer in the injection tube can be pushed into the first injection tank, thereby avoiding its waste.
