Description

Technical Field

[0001] The invention relates to the technical field of hemorrhoid treatment, in particular to an ointment injection device for hemorrhoid treatment. Background Art

[0002] Hemorrhoids, commonly known as hemorrhoids, are common anorectal diseases caused by congestion or congestion and swelling of the venous plexus at the anal canal or lower rectum. Hemorrhoids can be divided into external hemorrhoids, internal hemorrhoids and mixed hemorrhoids. The causes include downward movement of anal cushions or varicose veins, as well as bad bowel habits, chronic diseases, low-fiber diet habits, etc. About 40% of patients have no symptoms. Common symptoms include bleeding during defecation, perianal itching, pain and prolapse of hemorrhoids. Early hemorrhoids may be asymptomatic, and depending on the type and severity of the disease, different symptoms may occur, including bleeding, perianal itching, pain and prolapse.

[0003] In the treatment of hemorrhoids, ointments or suppositories are usually injected or squeezed into the anus for treatment. In order to facilitate the injection of ointments, some ointments are placed inside the cartridge of the injection device for patients to inject. When injecting the medicine, the patient is first required to squat and expand the anus, then aim the medicine outlet at the anus, and then push the piston rod inside the medicine storage cartridge to inject the medicine into the anus. However, in order to ensure sufficient ointment, the medicine storage cartridge will have a certain length, so the piston rod extends a long distance. In order to push the piston rod, the patient's hand must at least reach the end of the medicine storage cartridge. Some patients with poor body flexibility or short arms find it difficult to do this when squatting, which is inconvenient for patients to operate alone. Summary of the invention

[0034] Working principle: When in use, first insert a finger into the adjusting groove 213 and twist it to adjust the damping size of the liquid pushing piston cylinder 205. When adjusting, twist the threaded adjusting column 211 through the adjusting groove 213. When the threaded adjusting column 211 is twisted, it will move inward or outward along the threaded cylinder 210. When it moves inward, it will squeeze the air, so that the elastic damping sheet 207 is compressed and expanded, so that it is close to the inner wall of the liquid pushing cylinder 202, so that the damping becomes larger. When it moves outward, it will increase the space of the air inside the active piston 204, thereby forming a negative pressure, so that the elastic damping sheet 207 is compressed and contracted, thereby gradually reducing the effect of sticking to the inner wall of the liquid pushing cylinder 202, so that the damping becomes smaller, and the damping of the liquid pushing piston cylinder 205 is adjusted to a suitable size; Then twist and remove the external thread pressure-proof cover 501 and the internal thread dust-proof cylinder 502, sleeve the internal thread injection docking cylinder 301 on the surface of the external thread injection docking head 103 and twist it, and insert the extrusion push head 104 into the medicine pushing piston 307 to complete the docking; When injecting medicine, one hand holds the docked device so that the medicine pushing positioning head 306 is aimed at the anus. When aligning, the foreign body sensation of the medicine pushing positioning head 306 is enhanced to ensure accuracy. After the medicine pushing positioning head 306 is aimed at the anus, the other hand presses the liquid pushing piston cylinder 205. The liquid pushing piston cylinder 205 squeezes the transmission fluid through the active piston 204. The transmission fluid enters the pressure cylinder 101 along the hydraulic extension hose 201 from the inside of the liquid pushing cylinder 202 to squeeze the squeezing push head 104 and the driven piston 105. The squeezing push head 104 slides out of the pressure cylinder 101 under pressure, and the reset tension spring 109 is stretched. The squeezing push head 104 pushes the medicine pushing piston 307 to slide, and the medicine pushing piston When 307 slides, the ointment inside the medicine storage cartridge body 302 and the anti-wear ball head 305 is pressed into the patient's anus along the medicine pushing positioning head 306, thereby completing the injection of medicine. After the injection is completed, the anti-wear ball head 305 is removed from the anus, and then the liquid pushing piston cylinder 205 is released, and the reset tension spring 109 is reset and contracted, thereby driving the extrusion push head 104 and the driven piston 105 to reset. After the extrusion push head 104 and the driven piston 105 are reset, the transmission fluid is squeezed back to the liquid pushing cylinder 202, thereby squeezing the active piston 204 to make the liquid pushing piston cylinder 205 slide outward. When injecting medicine, the hydraulic extension hose 201 can be used to wrap the liquid pushing cylinder 202 in front of the patient to avoid excessive extension of the hand; When applying the ointment, the internal threaded coating docking tube 401 is sleeved on the surface of the external threaded coating docking joint 303 and tightened, pressing the liquid pushing piston cylinder 205, and the liquid pushing piston cylinder 205 squeezes the transmission fluid through the active piston 204. The transmission fluid enters the pressure-bearing cylinder 101 along the hydraulic extension hose 201 from the inside of the liquid pushing cylinder 202 to squeeze the extrusion push head 104 and the driven piston 105. The extrusion push head 104 slides outward from the pressure-bearing cylinder 101 under pressure, and the reset tension spring 109 is stretched, and the extrusion push head 104 pushes the medicine pushing piston 307 to slide. When the medicine pushing piston 307 slides, the ointment inside the medicine storage cylinder body 302 and the anti-wear ball head 305 is pressed into the extension tube 403 along the medicine pushing positioning head 306, and then penetrates into the sponge smearing block 406 along the medicine discharging seam 405, so that the ointment is penetrated inside the sponge smearing block 406, and then the sponge smearing block 406 penetrated with the ointment is applied to the affected area.
