Description

Technical Field

[0001] This invention relates to the field of fascial pressure measuring instruments, specifically a disposable automatic fascial pressure measuring instrument. Background Technology

[0002] With the development of transportation, construction, and technology, people are moving faster, higher, and farther. However, various traffic accidents, workplace injuries, and natural disasters are occurring frequently. Due to the increase in crush injuries and limb fractures, orthopedic surgeons are facing unprecedented pressure. Clearly, a significant factor contributing to this situation is a condition called compartment syndrome. If not detected or treated promptly, it can lead to limb loss and even endanger the patient's life. Currently, there are no specialized instruments for measuring compartment pressure in China. Compartment pressure measurement in China generally uses the Whitesides method, which monitors the pressure within the lower leg compartment using a needle device. Compartment syndrome is a series of early symptoms and signs caused by acute ischemia and hypoxia of the muscles and nerves within the osteofascial compartment formed by bone, interosseous membrane, intermuscular septum, and deep fascia. It is also known as acute compartment syndrome or osteofascial septum syndrome.

[0003] The "Automatic Fascial Compression Measuring Instrument" disclosed in application number "CN101530322A" is also an increasingly mature technology, "involving the fields of mechanical automation and measurement and control. This instrument consists of the following parts: ① uniform injection device ② pressure transmission device ③ display and control section ④ housing and power supply. When the fluid flow rate is very low, the pressure at each port of the three-way valve in the pressure transmission device is approximately equal, and the pressure at both ends of the air column at the sensor end is equal. The measurement error depends on the liquid flow rate, tubing material, length, diameter, height, etc. This error can be calculated by the measurement and control section, and the actual pressure value can be obtained by the difference method. The uniform injection device is a component that ensures pressure balance and low flow rate. Due to the air column barrier at the sensor end, the liquid will not be contaminated, thus ensuring the aseptic requirements of the measurement process. This instrument uses a single-chip microcomputer to control the coordinated work of each component to complete the accurate measurement of fascial compartment pressure. This invention is mainly used for the diagnosis of compartment syndrome in orthopedic trauma, thus serving as an indicator for deciding whether to perform decompression.

[0004] Compartment syndrome is a serious clinical emergency, commonly occurring in the forearm and lower leg. If not diagnosed and treated promptly, it can lead to muscle necrosis, nerve damage, and even amputation. Traditional methods of fascial pressure measurement suffer from problems such as complex procedures, inaccurate measurements, and cross-infection due to repeated use.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a disposable automatic fascial compression measuring instrument: 1. During the evacuation of air from the fascial compartment, in order to inject saline solution once and monitor the pressure inside the fascial compartment, the rotation of the first motor drives the first gear to rotate. During the rotation of the first gear, it is easy to drive the first gear rack to rotate. This rotation of the first gear rack meshes with the first gear rack, thereby driving the first push rod at one end of the first gear rack to pull.

The LCD screen displays the pressure data inside the fascial compartment, and the microcontroller controls the electronic components on the measuring instrument to facilitate pressure detection within the fascial compartment. When the pressure gas inside the fascial compartment changes, a suction tube draws it out, allowing for pressure measurement via a pressure gauge. This enables medical personnel to more intuitively detect pressure changes. Simultaneously, a pressure sensor further facilitates monitoring of the fascial compartment pressure and obtains accurate data. Attached Figure Description

For example, they can refer to a fixed connection or configuration, a detachable connection or configuration, or an integral connection or configuration. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] like Figures 1-7 As shown, the disposable automatic fascia compression measuring instrument proposed in this invention includes a measuring instrument housing 1, a control mechanism 2 is fixedly connected to the bottom of the measuring instrument housing 1, and a suction mechanism 3 is fixedly connected to one side of the inside of the measuring instrument housing 1. An injection mechanism 4 is installed on the other side of the interior of the measuring instrument housing 1; A monitoring mechanism 5 is installed on the top of the suction mechanism 3.

[0026] The control mechanism 2 includes a fixed plate 201, a wireless signal receiving module 202 fixedly connected to the top of the fixed plate 201, a wireless signal transmission module 203 provided on one side of the wireless signal receiving module 202, an analysis module 204 provided on one side of the wireless signal transmission module 203, and a data recording module 205 provided on one side of the analysis module 204.

[0027] In practical use, when monitoring the pressure inside the fascia chamber, the wireless signal receiving module 202 and the wireless signal transmission module 203 work together to facilitate the transmission or reception of data collected on the internal pressure inside the fascia chamber, thereby facilitating the monitoring of the pressure inside the fascia chamber. The analysis module 204 controls the pressure inside the fascia chamber, and the data recording module 205 facilitates the recording of pressure data inside the fascia chamber.

[0028] The suction mechanism 3 includes a first motor 301 fixedly connected to the inside of the measuring instrument housing 1, a first gear 302 fixedly connected to the bottom end of the first motor 301, a first gear rack 303 meshing with one side of the first gear 302, a first slider 304 fixedly connected to the top of the first gear rack 303, the top of the first slider 304 slidably connected to the first slide rail 305, a first push rod 306 fixedly connected to one end of the first gear rack 303, a first piston 307 fixedly connected to one end of the first push rod 306, a suction cylinder 308 sleeved on the outside of the first piston 307, and a first delivery pipe 309 fixedly connected to one side of the suction cylinder 308.

[0029] In practical use, when evacuating the air from the fascia chamber, in order to inject physiological saline and monitor the pressure inside the fascia chamber, the rotation of the first motor 301 drives the first gear 302 to rotate. During the rotation of the first gear 302, it is easy to drive the first gear 302 to rotate. The rotation of the first gear 302 meshes with the first gear rack 303, thereby driving the first push rod 306 at one end of the first gear rack 303 to pull. The first push rod 306 drives the first piston 307 to move inside the suction cylinder 308, so that the suction cylinder 308 extracts the air from the fascia chamber through the first delivery pipe 309.

[0030] The injection mechanism 4 includes a second drive motor 401 fixedly connected to the top of the measuring instrument housing 1. A second gear 402 is fixedly connected to the transmission end of the second drive motor 401. A second gear rack 403 is meshed with one side of the second gear 402.

[0031] In practical use, during the injection of fluid into the fascial compartment, in order to detect compartment syndrome, the pressure change inside the fascial compartment is detected by injection. The rotation of the second drive motor 401 drives the second gear 402 to rotate, so that the second gear 402 can mesh with the second gear rack 403 during rotation, facilitating the pushing of the second gear rack 403. At the same time, the pushing of the second gear rack 403 facilitates the adjustment of the second push rod 404, so that the second push rod 404 can push the second piston 405 to extend and retract inside the syringe barrel 406, so that the saline solution inside the syringe barrel 406 is injected into the fascial compartment, thereby facilitating pressure detection. The injection solution is introduced through the second delivery tube 407.

[0032] One end of the first delivery pipe 309 and the second delivery pipe 407 are respectively connected to the three-way valve 6. One end of the three-way valve 6 is connected to the connecting pipe 601, and one end of the connecting pipe 601 is fixedly connected to the needle 602.

[0033] In practical use, the three-way valve 6 facilitates injection and delivery, and also allows gas inside the fascia chamber to be easily discharged into the suction cylinder 308. The needle 602 facilitates insertion into the fascia chamber.

[0034] The monitoring mechanism 5 includes an LCD screen 501 fixedly connected to the top of the measuring instrument housing 1, a microcontroller 502 fixedly mounted on one side of the LCD screen 501, a first detection tube 503 fixedly connected to the top of the measuring instrument housing 1, the bottom end of the first detection tube 503 being connected to the top of the suction cylinder 308, a gas supply pipe 505 fixedly connected to the top of the first detection tube 503, a pressure gauge 506 fixedly connected to the top of the gas supply pipe 505, a pressure sensor 507 fixedly connected to the top of the gas supply pipe 505, and a second detection tube 504 fixedly connected to one end of the gas supply pipe 505, the bottom end of the second detection tube 504 being connected to the suction cylinder 308.

[0035] In practical use, the LCD screen 501 displays the pressure data inside the fascial compartment, and the microcontroller 502 controls the electronic components on the measuring instrument to facilitate pressure detection inside the fascial compartment. The first detection tube 503 and the second detection tube 504 allow for the suction of gas inside the fascial compartment when the pressure changes, which is then detected by the pressure gauge 506. This allows medical personnel to more intuitively detect pressure changes. The pressure sensor 507 is a high-precision disposable sensor that converts the pressure inside the fascial compartment into an electrical signal. This sensor has good biocompatibility and anti-interference performance, ensuring measurement accuracy and equipment safety. This sensor combination facilitates the monitoring of fascial compartment pressure.

The pressure sensor 507 is also electrically connected to an external power supply via a microcontroller 502. Working principle: Insert the injection device needle 602 of the device into the patient's fascia compartment, ensuring accurate insertion without damage, and press the operation button to start the measurement process; The device automatically injects the liquid pre-filled in the syringe 406 into the fascial chamber. At the same time, the pressure sensor 507 detects the pressure change in the fascial chamber. After the measurement is completed, the device automatically stops the injection and displays the measurement result on the LCD screen 501. Doctors can make diagnostic and treatment decisions based on the displayed pressure value. After the measurement is completed, the disposable injection device and pressure sensor 507 are removed from the equipment and disposed of in accordance with medical waste disposal regulations; Clean and disinfect the other parts of the equipment in preparation for the next use.

[0040] Additional notes: The syringe 406 is pre-filled with saline or other suitable liquid. The liquid is injected into the fascial compartment through the injection tubing. The injection device is designed for single use to avoid cross-infection caused by reuse. It consists of a microcontroller 502, an LCD screen 501, and operation buttons.
