Anal sphincter muscle strength detection device

Abstract

The invention provides an anal sphincter muscle strength detection device which comprises a shell, a force measuring mechanism and a control circuit. The shell is of a cylindrical structure and is provided with an insertion part and a display part, the end of the insertion part is smooth, and a display screen is arranged on the display part; the force measuring mechanism is provided with acting plates uniformly arranged at the outer side of the shell in a surrounding manner, a center rod arranged in the shell in a sliding manner in the axial direction of the shell and a pressure sensor corresponding to one end of the center rod, and the center rod is in transmission connection with the acting plates so that pressure borne by the acting plates can be transmitted to the pressure sensor; and the control circuit is arranged in the shell, the control circuit is provided with a single-chip microcomputer minimum system, and the single-chip microcomputer minimum system is connected with a power supply circuit, the display screen and the pressure sensor. The anal sphincter muscle strength detection device can detect the muscle force of the anal sphincter of a patient, the muscle force is displayed in a numerical value manner through the display screen, the defect that finger detection is affected by subjective factors of medical staff is overcome, and operation is convenient and fast.

Description

Technical field [0001] The present invention belongs to the technical field of medical testing equipment, and in particular, the present invention relates to an anal sphincter muscle muscle strength detecting device. Background technique [0002] Anal sphincter is a muscle sphincter and an eliminate muscle, both of which are different. The internal sphincter is dominated by an autonomous nervous system, just like the internal organs, is not subject to will control, and the surrounding muscles are controlled by the neurotrophic deficiency of neurotactoma in the pyrogen, and is affluent. [0003] In rectal surgery, the anal function is required to evaluate the anal sphincter during the low orientation of the anus. It is important to work properly after surgery. In addition, there are some basin-bottomed benign diseases, and anal sphincter contraction capacity is also required. At present, it is commonly used in clinically refers to the anus. It is inserted into the patient anus, al...

Problems solved by technology

At present, the commonly used finger test is used in clinical practice, inserting fingers into the patient's anus, allowing the patient to actively contract the anus, and feel the contraction force of the anal sphincter through the fingers. This detection method is easily affected by the doctor's subjective factors and lacks objective judgment standards.

[0004] In the prior art, for example, the Chinese invention patent application with the application number CN202011183770.6 discloses an anal sphincter quantification pressure measuring device. The end of the push rod provided with the air bag is inserted into the anus of the patient through the push handle, so that through the contraction of the air bag Obtain the strength changes of the patient's anal sphincter; although it can obtain the muscle strength of the anal sphincter through the airbag and the force sensor collection device, it needs to be connected to an external display device to display the muscle strength value, which is not convenient to use

[0005] Furthermore, the Chinese utility model patent with the application number CN202020399856.1 discloses an anal sphincter function evaluation device. When medical personnel inject gas into the air bag through the intake catheter, the pressure gauge will measure the pressure value in the air bag in real time, thereby It is convenient to achieve the rated air pressure in the airbag, even if the existing inflation device such as a syringe can be used to achieve the purpose of precise gas injection; it needs to use a syringe for gas injection during detection, which is more cumbersome to operate and less convenient to use
