AI Technical Summary
Existing muscle strength testing instruments are difficult to adapt to testing small tensions in patients after anesthesia. Their complex structure and unsuitability can easily lead to premature extubation and cause secondary injury.
A simple pull-type muscle strength tester was designed, which includes a pressure sensor, a monitoring component, a handle, a pull rope, and a protective sleeve. It adopts a soft structure made of silicone material and detects muscle strength by pulling the rope against the handle. The monitoring component displays the muscle strength level.
It enables a simple and stable way to detect muscle strength in patients after anesthesia, avoiding the risk of premature extubation, reducing the possibility of re-intubation, and protecting the health of patients.

Abstract
Claims
1. A simple test instrument for pull type muscle strength, comprising a pressure sensor and a monitoring assembly, the pressure sensor is electrically connected to the monitoring assembly, the monitoring assembly is configured with a battery and a charging interface, a master controller, a display screen to be able to receive and display pressure; characterized in that: It also includes a handle and pull rope, a hanging base, and a protective sleeve. The handle is provided with an axially penetrating hole. The two ends of the pressure sensor are respectively provided with hanging bases. One end of the pull rope is connected to the hanging base, and the other end of the pull rope passes through the hole in the handle. The protective sleeve is axially hollow to form a cavity, and the pressure sensor and the hanging base are arranged in the cavity. The side wall of the protective sleeve is provided with a groove. The inner side wall of the groove is provided with a charging port that penetrates the outer wall of the protective sleeve. The monitoring component is disposed in the groove, and the charging interface is arranged at the charging port.
2. The simple test instrument of paired-pull muscle force according to claim 1, characterized in that: The inner walls at both ends of the casing are respectively provided with radially inwardly contracting limiting rings.
3. The simple test instrument of paired-pull muscle force according to claim 2, characterized in that: The suspension base includes a base plate and a lifting ring. The lifting ring has a U-shaped structure, with the open end of the lifting ring located on the outer end face of the base plate. One end of the pull rope is tied to the closed end of the lifting ring, and the inner end face of the base plate is connected to a pressure sensor.
4. The simple test instrument of paired-pull muscle force according to claim 3, characterized in that: The width of the end face of the seat plate is smaller than that of the cavity and larger than that of the inner diameter of the limiting ring.
5. The simple test instrument for measuring the muscle strength according to claim 1, wherein: The inner bottom wall of the groove of the protective sleeve is provided with a wiring hole that connects to the cavity; wherein, the wiring hole is rectangular and forms a stepped groove structure with the groove.
6. The simple pull-type muscle strength tester according to claim 1, characterized in that: The protective sleeve is a soft cylindrical structure made of silicone material.
7. The simple test instrument of claim 1, wherein: The outer layer of the pull rope is a silicone layer with a thickness of 1-3mm.
8. The simple test instrument of claim 1, wherein: The outer layer of the handle is a silicone layer with a thickness of 1-3mm.
