Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an intelligent compression cuff. Background Art

[0002] In clinical medicine, when medical staff perform intravenous infusion or venous blood collection, they often need to tighten a compression cuff to replenish the body's blood volume and make the veins visible. A compression cuff is also called a tourniquet.

[0003] Most of the existing compression cuffs are in the form of a rubber tube. When users tighten the cuff through the rubber tube, they usually need to use both hands to operate. When adjusting the tightness, they can only do so by removing it and tightening it again, which is time-consuming, labor-intensive, and has poor practicality.

[0004] The purpose of applying a compression cuff is to increase local venous filling and facilitate puncture. If the compression cuff is used for more than 1 minute, the local blood oxygen content can be reduced, lactic acid can be increased, and pH can be decreased. If the compression lasts for 3 minutes, bilirubin, cholesterol, AST, ALP, etc. can be increased by more than 5%. After the operation is completed, the compression should be released in time. If the cuff is used for too long, blood return will be blocked, blood vessels will expand, blood pressure in the capillaries will increase, blood flow will decrease, and fluid loss will occur. Continuous high pressure in the veins will reduce water and electrolytes in the tissue return, and the concentration of proteins and protein complexes will increase; blood flow will be blocked, and the activity of fibrin will increase; cells will continue to metabolize, which will increase the metabolic product lactic acid, etc. Therefore, the cuff should be used for less than 1 minute. After the needle enters the blood vessel, it is advisable to relax the cuff.

[0005] Most of the existing cuffs are disposable, which is wasteful, and patients often forget to take them off after use. When patients take them off by themselves, it is inconvenient to operate with one hand, and the intelligent level is low, resulting in poor user effect. Summary of the invention

The long groove 13 is parallel to the central axis of the rotating shaft 12, and the cross section of the long groove 13 is a convex shape. A fixed block 21 is set at one end of the compression belt 4. When the opening and closing structure 14 is opened, the fixed block 21 slides from the end of the rotating shaft 12 into the long groove 13 to prevent the fixed block 21 from sliding out of the outer cylindrical surface of the rotating shaft 12. The opening and closing structure 14 can be a variety of structures, which can be opened and closed to facilitate the fixed block 21 to enter or leave the long groove 13.

[0057] In this embodiment, a bottom plate 30 can be provided on the bottom surface of the shell 2. The bottom plate 30 and the rotating shaft 12 are an integral structure and can be detachably connected to the shell 2 to avoid direct contact between the patient and the shell 2.

[0066] The interaction between the devices can utilize a variety of signals and technologies to achieve the above functions. These signals and technologies include: orthogonal signals, CDMA, TDMA, FDMA, OFDMA, ultra-wideband signals, chirp signals, laser signals, and many other signals. The signals between the microprocessor 18 and the devices can be modulated (AM, FM, PSK, FSK, MSK, QAM or any other possible modulation can be used) or can be encoded or configured in other ways to include timing, synchronization, control, data, multipath signal component identification, security code, information to ensure proper operation, and redundancy.

The microprocessor 18 and the adjustment device 3, the opening and closing device 1, the display screen 6, the alarm device 20 and the timer 19 can receive power via a wired or wireless connection, or can receive power from a disposable battery or a rechargeable battery.

[0068] The working principle of the present invention is:

[0069] One end of the compression belt 4 is connected to the housing 2 through the opening and closing device 1, and the other end of the compression belt 4 is connected to the housing 2 through the adjusting device 3, and the closed ring 5 is put on the patient's arm or leg. The tightness of the compression belt 4 is adjusted by adjusting the button 10, and the timer 19 is adjusted to set two time points, which are displayed on the display screen 6. Pull out the blood vessel development lamp 15, and adjust the appropriate angle through the folding bracket 16 so that the blood vessel development lamp 15 can illuminate the vein for easy operation. After the operation is completed, open the opening and closing device 1 and remove the compression belt. If the operator forgets to remove it, when the first time point is reached, the alarm device 20 will alarm to remind the operator to remove the compression belt 4. If the operator walks away and does not hear it, when the second time point is reached, the microprocessor 18 drives the opening and closing device 1 to automatically disconnect and release the compression, which is particularly suitable for patients with limited mobility or unconsciousness to avoid excessive compression time caused by inconvenient operation.

[0070] The display screen 6 selected in this embodiment is VGG12864E-S002, with a resolution of 128×64 and a built-in 64×64 display data RAM. Each bit of data in the RAM corresponds to the light or dark state of a point on the display screen 6. Therefore, two column drive controllers are used, each with 64 rows of output row drivers. The connection between the VGG12864E module and the microprocessor 18 is indirect control. The interface circuit of the display screen 6 is as follows: Figure 7 As shown, the commonly used chip for the interface circuit is P89C669. Port P1 of P89C669 is used as the data port, P3.2 and P3.3 are used as chip select signals, P3.4 is used as a reset control signal, P3.5 is a register select signal, P3.6 is an enable signal E, and P3.7 is a read-write signal.

[0071] The alarm circuit selected in this embodiment is controlled by the P3.7 port of the single-chip microcomputer, outputs an alarm signal, and drives the alarm circuit until the reset key RESET and the power key are pressed.

[0072] The alarm circuit consists of a 555 timer, a sounder and a common light-emitting diode. The circuit diagram is as follows: Figure 8 shown.

[0073] The 555 timer is connected to a low-frequency multivibrator, and its control voltage input and output terminal 5 is connected to the P3.7 terminal of the microprocessor 18 based on AT89C51, and is controlled by the pulse signal output from the P3.7 pin. Due to the charging and discharging effect of capacitor C4, when P3.7=1, the oscillation frequency of the 555 output pulse is low, and when P3.7=0, the oscillation frequency of the 555 output pulse is high. The pulse signal is added to the sounder through the separated capacitor C2, and the sounder will emit two kinds of high and low alternating sounds. At the same time, the high and low level pulse signal output from the P3.7 pin with an interval of 1s is added to the light-emitting diode LED through the resistor R1, and the LED will flash and emit light, achieving the effect of simultaneous sound and light alarm.
