Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an anorectal medication device. Background Art

[0002] Anorectal administration refers to a method of delivering drugs into the intestine through the anus, where they are rapidly absorbed by the rectal mucosa into the general circulation to exert their efficacy in treating systemic or local diseases. Rectal administration in the prior art is mainly achieved by the following three methods: retention enema, rectal drip, and suppository insertion.

[0003] In the traditional way of applying medicine in the rectum, medical staff usually use a syringe, connect a catheter to the syringe, insert the catheter from the patient's anus into the rectum, and apply the medicine in the rectum. However, when injecting the medicine, the medicine flows out of the catheter and falls under the action of gravity, so it can only contact a part of the rectal wall, making the contact area between the medicine and the rectal wall small, resulting in the patient's inability to absorb the medicine well. In addition, the traditional rectal drug delivery device is a disposable device, which causes a waste of resources. Utility Model Content

[0004] In order to overcome the shortcomings of the existing anorectal medication device, such as small medication area and non-reusability, the utility model provides an anorectal medication device which can enlarge the medication area and can be reused.

[0005] The technical solution of the utility model is: an anorectal drug delivery device, including a stretching component and a medicine application component, the stretching component includes a mounting ring, a limit plate and an elastic sheet, the mounting ring is symmetrically connected to the limit plate, and four elastic sheets are connected to the mounting ring in an interval manner, the medicine application component includes a liquid storage cylinder, a cylinder cover, an extrusion ring, a nozzle, a connecting rod, a first fixed plate, a sliding rod, a second fixed plate and a piston, the liquid storage cylinder is detachably connected to the cylinder cover, the middle part of the liquid storage cylinder is clamped with an extrusion ring, a side of the liquid storage cylinder away from the cylinder cover is connected to a plurality of nozzles, the cylinder cover is connected to a connecting rod, the side of the connecting rod away from the cylinder cover is symmetrically connected to the first fixed plate, a sliding rod is slidably connected between the side of the connecting rod away from the cylinder cover and the cylinder cover, one end of the sliding rod away from the liquid storage cylinder is connected to the second fixed plate, a piston is slidably connected in the liquid storage cylinder, and the piston is fixedly connected to the end of the sliding rod, the medicine application component can slide in the stretching component and squeeze the elastic sheet through the extrusion ring to stretch the elastic sheet.

[0006] As a preferred technical solution of the utility model, each edge of the elastic sheet is chamfered.

[0007] As a preferred technical solution of the utility model, all parts of the anorectal medication dispenser are made of stainless steel, which is convenient for high-temperature disinfection to achieve the effect of repeated use.

[0008] As a preferred technical solution of the utility model, it also includes a limiting block. Limiting grooves are provided on the facing side walls of the four elastic sheets. Four limiting blocks are circumferentially connected to the extrusion ring, and the limiting blocks can slide in the limiting grooves.

[0009] As a preferred technical solution of the utility model, it also includes a sealing ring, and a sealing ring is arranged at the connection between the liquid storage cylinder and the cylinder cover.

[0010] As a preferred technical solution of the utility model, a buffer spring is also included, and a buffer spring is connected between the second fixing plate and the connecting rod.

[0011] Beneficial effects: 1. The utility model cooperates with the medicine-applying component and the expansion component. The extrusion ring expands the patient's rectal wall by squeezing the elastic sheet, thereby increasing the contact area between the intestinal wall and the medicine solution, and then sprays the medicine solution around the liquid storage cylinder through the nozzle, so that the rectal wall can better contact and absorb the medicine solution. At the same time, the parts of the anorectal drug delivery device can also be quickly disassembled for high-temperature disinfection, which is convenient for reuse, thereby reducing medical costs.

[0012] 2. The utility model makes it difficult for the elastic sheet to rotate by the cooperation of the limit block and the limit groove, thereby reducing the patient's discomfort. The buffer spring is optimally arranged to enable medical staff to push out the medicine at a slower speed, avoiding pushing out a large amount of medicine at one time due to improper operation, which causes greater irritation to the patient.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0019] Embodiment: An anorectal drug delivery device, such as Figure 1-Figure 4 As shown, it includes a spreading component and a medicine applying component, the spreading component includes a mounting ring 1, a limiting plate 2 and an elastic sheet 3, the mounting ring 1 is symmetrically connected to the limiting plate 2, and four elastic sheets 3 are spacedly connected to the mounting ring 1, and each edge of the elastic sheet 3 is chamfered to avoid damage to the patient's intestines. The medicine applying component includes a liquid storage cylinder 5, a cylinder cover 51, an extrusion ring 6, a nozzle 8, a connecting rod 9, a first fixed plate 10, a sliding rod 11, a second fixed plate 12 and a piston 13, the liquid storage cylinder 5 is detachably connected to the cylinder cover 51, the middle part of the liquid storage cylinder 5 is clamped with the extrusion ring 6, and the side of the liquid storage cylinder 5 away from the cylinder cover 51 is connected with multiple A nozzle 8 is provided, and a connecting rod 9 is connected to the cylinder cover 51. A first fixed plate 10 is symmetrically connected to the side of the connecting rod 9 away from the cylinder cover 51. A sliding rod 11 is slidably connected between the side of the connecting rod 9 away from the cylinder cover 51 and the cylinder cover 51. An end of the sliding rod 11 away from the liquid storage cylinder 5 is connected to a second fixed plate 12. A piston 13 is slidably connected inside the liquid storage cylinder 5. The piston 13 is fixedly connected to the end of the sliding rod 11. The medicine applying component can slide in the stretching component and squeeze the elastic sheet 3 through the squeezing ring 6 to stretch the elastic sheet 3. All components of the anorectal drug delivery device are made of stainless steel, which is convenient for high-temperature disinfection to achieve the effect of repeated use.

[0020] First, the medical staff performs high-temperature disinfection on the anorectal drug delivery device, and then puts it aside for use. Then, the medical staff guides the patient to adjust to a suitable body position, takes out the expansion component of the anorectal drug delivery device, and inserts the elastic sheet 3 from the anus to the rectum on the side away from the mounting ring 1 until the second fixing plate 12 fits with the perianal skin. At this time, the anus is expanded to the same size as the mounting ring 1, and then takes out the drug application component of the anorectal drug delivery device, first pushes the sliding rod 11 so that the sliding rod 11 drives the piston 13 to slide in the direction away from the cylinder cover 51, and then immerses the liquid storage cylinder 5 in the medicine so that the medicine submerges the nozzle 8, and pulls the sliding rod 11 to make the piston 13 move closer to the cylinder cover 51. The piston 13 is pushed by the sliding rod 11 to slide in a direction away from the cylinder cover 51, and the medicine in the liquid storage cylinder 5 is squeezed out from the nozzle 8. Since the nozzle 8 is arranged along the circumference of the liquid storage cylinder 5, the medicine can be sprayed all around, thereby making a larger contact with the rectal wall, increasing the drug administration area, and making the patient's rectum better absorb the medicine.

[0021] like Figure 1 As shown, it also includes a limiting block 7. The limiting grooves 4 are arranged on the facing side walls of the four elastic sheets 3. Four limiting blocks 7 are connected to the extrusion ring 6 along the circumferential direction. The limiting blocks 7 can slide in the limiting grooves 4.

[0022] When the extrusion ring 6 slides on the elastic sheet 3, the limiting block 7 slides in the limiting groove 4 at the same time, so that the elastic sheet 3 can be limited to prevent the elastic sheet 3 from rotating and causing discomfort to the patient.

[0023] like Figure 4 As shown, a sealing ring 14 is also included. The sealing ring 14 is arranged at the connection between the liquid storage cylinder 5 and the cylinder cover 51. The arrangement of the sealing ring 14 can prevent the liquid medicine from leaking from the liquid storage cylinder 5 and the cylinder cover 51.

[0024] like Figure 1 As shown, a buffer spring 15 is also included. The buffer spring 15 is connected between the second fixed plate 12 and the connecting rod 9. The setting of the buffer spring 15 can generate a certain resistance when pushing the sliding rod, so that the medical staff can push out the medicine at a slower speed, avoiding pushing out a large amount of medicine at one time due to improper operation, causing greater irritation to the patient.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
