Abstract

An electronic digital display portable elastic soft bladder intracystic pressure measuring instrument has a ring-shaped photoelectric detection board on the side wall of its bottom collar. When measuring under bright light, the lower end of the collar of the measuring instrument is close to the skin and the surface of the sphere. The round cap of the pressure measuring needle is pushed by the internal pressure of the subcutaneous expansion bladder and other soft bladders to displace the main axis in the direction of the pressure spring. Once the bottom collar is in full contact with the skin surface, the light is completely blocked, the current of the photoelectric detection board is terminated, and the displacement detector on the integrated circuit board is activated to detect and maintain the measured displacement value. The displacement value is proportional to the level of the intracystic pressure, and the displacement value can also be easily converted into pressure.

Description

Portable Elastic Soft Capsule Intracapsular Pressure Tester

The invention is a tool for measuring the internal pressure of a subcutaneous expansion sac and other soft sacs in the process of skin expansion.

At present, in the expansion of skin and soft tissues, it is necessary to obtain the internal pressure of subcutaneous expansion capsules and other soft capsules through directly connected gas-liquid pipelines, which will inevitably cause interference to the real internal pressure. However, when professional hardness testing instruments work in a portable manner, the determination of testing sampling points cannot be standardized and unified, resulting in large errors.

Therefore, the present invention provides a portable device, which is used to simply and conveniently measure the internal pressure and surface tension of the capsule through the body surface, without causing interference to the internal pressure during the measurement process, and the standardization of sampling ensures the accuracy of the detection results.

The technical scheme adopted by the present invention to solve the technical problem is: an electronic digital display portable elastic soft capsule internal pressure measuring instrument, the side wall of the bottom collar of it is an annular photoelectric detection plate, and the pressure measuring instrument with a round cap The needle passes through the central circular hole at the bottom, and is connected with the pressure spring through the main shaft, and the grid on the main shaft corresponds to the displacement detector of the integrated circuit board. When measuring under bright light, when the lower end of the collar of the measuring instrument is close to the skin and the surface of the sphere, the round cap of the indenter is pushed by the internal pressure of the subcutaneous dilatation sac and other soft sacs to push the main shaft toward the direction of the pressure spring. The bottom ring is in full contact with the skin surface, the light is completely blocked, the current of the photoelectric detection board is terminated, the displacement detector on the integrated circuit board is activated, and the measured displacement value is detected and maintained. The displacement value is proportional to the pressure in the capsule. Proportional, the pressure value it represents is equal to the restoring force after the spring is compressed. By pre-determining the corresponding relationship between the displacement value and the pressure value, the displacement value can also be easily converted into pressure.

Due to the adoption of the above scheme, the internal pressure and surface tension of the soft capsule can be easily measured through the surface, and the photoelectric detection realizes the standardization of detection.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Among Fig. 1, electronic digital display portable elastic soft capsule internal pressure tester, its bottom collar (8) sidewall is the annular photoelectric induction plate (9), has the pressing pin (1) of round cap (1) 2) Go through the central round hole at the bottom and connect with the pressure spring (5) through the main shaft (3). The force of the pressure spring (5) is adjusted and corrected by moving the pressure regulating screw (6) up and down on the fixed partition (7) . The keyboard (13) on the integrated circuit board (11) is corresponding to the window hole on the display screen (14) and the casing (15). The upper end of measuring instrument has power supply (16) pool.

In Figures 2 and 3, the working process of the electronic digital display portable elastic soft capsule internal pressure measuring instrument is as follows: when measuring under bright light, the lower end of the collar (8) of the measuring instrument is close to the skin and the surface of the sphere (17) At this time, the round cap (1) of the indenter (2) is pushed by the internal pressure of the subcutaneous expansion sac and other soft sacs to push the main shaft (3) to move in the direction of the pressure spring (5). Once the bottom ring is in full contact with the skin surface , the light is completely blocked, the current of the photoelectric sensing detection board (9) is terminated, and the displacement detector on the integrated circuit board (11) is started to sample and detect and maintain the measured displacement value, which is proportional to the level of the intracapsular pressure, The pressure value it represents is equal to the restoring force after the spring is compressed. By pre-determining the corresponding relationship between the displacement value and the pressure value (conversion coefficient), the displacement value can also be easily converted into pressure.
