Description

Anal sphincter function evaluation device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an anal sphincter function evaluation device.

Background

The main function of the anal sphincter is to assist and control defecation, an important tissue structure at the end of the lower digestive tract. Wherein the internal sphincter is formed by the deformation of the internal ring muscle of the rectal wall descending to the anal canal, surrounds the upper 2/3 part of the anal canal, and is surrounded by the superficial and deep layers of the combined longitudinal muscle and the external sphincter; belongs to smooth muscle, is innervated by vegetative nerves, is involuntary, and is not innervated by consciousness; it only needs the physiological function of closing anal canal and assisting defecation; the rectum pressure-maintaining device is in a contraction state at ordinary times, excrement, liquid and gas in the rectum are prevented from flowing out, a certain pressure of the rectum is maintained, the contraction state can work continuously, fatigue is not easy, but spasm is easy, and the anus is narrow, defecation is difficult or pain is caused. The external sphincter is the outermost muscle of the anal canal, belongs to the striated muscle and is divided into three layers, namely subcutaneous, superficial and deep layers; receptor innervation, voluntary muscle; the main functions are closing anus and controlling defecation, but the anus is easy to fatigue, and if the contraction time is long, the fecal incontinence is easy to occur.

Clinically, various perianal diseases are caused by anatomical or functional abnormalities of anal sphincters, for example, anal fissure can be caused by sphincter spasm, functional anorectal pain can be caused by hypoxia of muscle tissues or abnormal innervation, fecal incontinence and constipation can be caused by sphincter contractile dysfunction or operation damage to normal anatomical structures, although the postoperative anatomical structures are complete, the functional recovery time is long, perianal pain is felt by patients, and the like, so that the life quality of the patients is seriously influenced.

Therefore, on the basis of treatment such as medicine, operation or acupuncture, the recovery condition of the anal sphincter is crucial to be evaluated, and the existing evaluation device has poor feedback effect, cannot provide clear feedback for medical staff in time, and can realize accurate evaluation only by measuring for many times.

Disclosure of Invention

As the preferred scheme of the utility model, the end of the pressure measuring conduit is provided with a pressure gauge interface, and the pressure gauge is detachably connected with the pressure gauge interface; the manometer can be dismantled and connect and make manometer repeatedly usable, when medical personnel finished the aassessment, can take off the manometer from the manometer interface preferentially, and the gaseous accessible pressure measurement pipe in the gasbag discharges this moment, is flat gas state after the gaseous part in the gasbag discharges, and medical personnel of being convenient for take out the gasbag from patient's anus in, have reduced patient's uncomfortable when taking out the gasbag and have felt.

As the preferred scheme of the utility model, the end part of the air inlet conduit is provided with an air injection interface which is used for being connected with the injector nipple in a plugging way; the setting of gas injection interface for medical personnel's accessible ordinary syringe need not to purchase extra air pump and other devices and uses in coordination for the gasbag injection gas, very big reduction the acquisition cost of hospital, thereby the expense when making the patient use reduces.

As the preferred scheme of the utility model, the air bag is made of elastic material and has a bullet structure; the fixed effect of ball gasbag department at patient's anus is better compared to the gasbag of bullet type, and the gasbag is difficult for producing when receiving patient's anal sphincter extrusion and slides, vertical accuracy when having guaranteed the aassessment.

As a preferable scheme of the utility model, a holding part is arranged at the tail end of the air bag, and the holding part is of a flat plate-shaped structure; medical personnel can hold the portion of gripping in order to fill in the gasbag to patient's anus, and traditional evaluation device needs medical personnel to hold the gasbag and fills in patient's anus with it when using, and patient's anus department is infected by the bacterium on medical personnel's hand easily.

As a preferable scheme of the utility model, the surface of the air bag is provided with scale strips along the length direction; the medical staff can observe the inserting depth of the air bag in time.

As a preferable scheme of the utility model, the surface of the air bag is provided with a ring groove along the circumferential direction; the anus of the patient can be embedded into the ring groove to limit the air bag to slide left and right relative to the anus of the patient.

Compared with the prior art, the utility model discloses the pressure value that the middle pressure gauge can be accurate feedback goes out because of extruding the gasbag and producing changes, and when medical personnel injected into gas in to the gasbag through the admission line, the manometer can the pressure value in the real-time measurement gasbag to be convenient for reach rated air pressure value in making the gasbag, even adopt current aerating device such as syringe can also reach the purpose of accurate gas injection.
