Description

Anal muscle strength and reflex detector

Technical Field: The present invention relates to the technical field of medical devices, and is an instrument for measuring anal muscle strength and reflex.

Background technology: For the diagnosis and treatment of patients with spinal cord injury in the shock stage, it is often judged by measuring the anal reflex whether the shock stage of the patient has disappeared. Currently, the presence or absence of contraction of the anus felt by fingers is clinically used as an index to judge. Due to the difference in finger sensation, not only the diagnosis is not objective, but also the slight contraction is sometimes difficult to detect, which leads to unreliable results and affects the diagnosis and treatment of patients.

SUMMARY OF THE INVENTION: The present invention provides a detection instrument that can quickly and objectively reflect anal muscle strength or reflex. It includes five parts: a pressure indicator, a pressure sensor, an inflatable ball, a three-way pipe and a pressure probe, wherein the pressure probe is composed of a probe rod and an air bag placed outside the probe rod. For ease of description, the accompanying drawings are introduced first.

The present invention is described in detail in conjunction with accompanying drawing now.

The present invention consists of a pressure indicator 1, a pressure sensor 2, a three-way pipe 3, an inflatable ball 4 and a pressure probe 5, wherein the pressure probe 5 includes a probe 6 and an air bag sheathed outside it. The pressure indicator 1 is connected with the pressure sensor 2 by a wire, and the pressure sensor 2 is connected with one end of the three-way pipe 3 through a rubber tube. The threads are matched so as to connect with the probe rod 6, and the air bag is sleeved on the outside of the probe rod 6 and fixed at the mouth of the tee pipe. The shape of the three-way pipe is an asymmetrical T-shape, and its side nozzle is located near the end connected to the pressure sensor 2, and is connected with the inflatable ball 4 through a rubber tube. The outer edges of the three nozzles of the three-way pipe are all provided with trapezoidal ribs to prevent the rubber tubes and airbags sheathed outside from slipping off. The probe 6 is in the shape of a hollow cylinder, the top is blunt and closed, and there are air holes around it, and the tail is open and screwed to the tee pipe through the external thread. When in use, first inflate with an inflatable ball, and the gas enters the air bag through the air hole of the probe 6. After the air bag is filled, close the inflation valve to prevent gas leakage, and clamp the rubber tube with a clip near the mouth of the three-way pipe. When the pressure is on, the pressure on the baroreceptor 2 is the same as the pressure on the airbag; gently insert the pressure probe 5 into the anus, and then adjust the pressure indicator to zero. At this time, the patient’s penis is pulled or the clitoris is squeezed. , then the sacral reflex makes the anal sphincter contract, causing the air pressure change of the air bag, which is transmitted to the baroreceptor 2, and the value change is displayed by the pressure display instrument. Even a slight change can be displayed, thereby reducing misdiagnosis or missed diagnosis.

The detection instrument of the invention is easy to operate, quick to detect, and can objectively reflect the change of anal muscle strength, thereby reflecting the treatment effect of spinal cord and cauda equina nerve injury in patients, and can be used for the detection of anal reflex and the evaluation of treatment effect of spinal cord and cauda equina nerve injury.

Detailed ways:

The pressure indicator and the pressure sensor used in the present invention can be selected from existing products in the market, and of course they can also be self-made on demand.

The three-way pipe used in the present invention has an asymmetrical T-shape, and is close to the end connected to the pressure sensor 2 with the mouth of the inflatable ball, so as to facilitate the operation when the pressure probe 5 is inserted into the anus. The nozzle connected to the pressure probe 5 is provided with an internal thread, which matches the external thread at the tail of the probe rod 6 . The outer edges of the three nozzles of the three-way pipe are all provided with trapezoidal external threads, and the external threads connected with the pressure probe 6 are slightly deepened and lengthened to prevent the air bag from slipping off.

The probe 6 of the present invention is hollow cylindrical, the top is blunt and closed, the length of the body is 3-8cm, the outer diameter is 0.3-0.6cm, and the pores around it can be hole-shaped or groove-shaped; the length of the tail is about 0.5cm, The outer diameter is based on the matching of the outer thread and the inner thread of the tee nozzle.

The size and shape of the air bag of the present invention are determined by the probe 6, and the length and diameter are slightly larger than the probe 6. Can be made into thin latex tubing of uniform texture to allow for a uniform tube shape when inflated.
