Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and particularly relates to an intelligent air bag pressurizing device used after pacemaker implantation. BACKGROUND

[0002] With the rapid development of cardiac intervention surgery, permanent artificial cardiac pacemaker implantation has become an important means for treating certain cardiac dysfunction caused by arrhythmia and is widely used in clinical practice. The surgery has important significance in saving patients' lives, improving cardiac function and improving patients' quality of life. The postoperative treatment and nursing of permanent pacemaker implantation is an important part of clinical work, among which, the compression hemostasis and protection of the incision and pocket site after operation are particularly crucial.

[0003] After permanent pacemaker implantation, the incision and pocket site of the patient are prone to common complications such as bleeding and hematoma, and the range of motion of the upper limb of the patient on the surgical side is limited. If the postoperative compression hemostasis method is improper, it is easy to cause adverse conditions such as incision bleeding, hematoma formation or incision dehiscence, thereby affecting the postoperative recovery effect.

[0004] At present, the commonly used postoperative compression hemostasis method in clinical practice is the sandbag compression method, that is, a sandbag is placed at the postoperative incision to compress and hemostasis the wound by using the weight of the sandbag. However, this method has many shortcomings in actual application. Since the self-weight of the sandbag is fixed, the pressure exerted by the sandbag on the wound cannot be adjusted, and it is difficult to accurately control according to the individual differences of patients and the needs at different postoperative time periods. During the compression process, the sandbag is prone to slip, especially when the patient's body position changes, the sandbag may slip to the tracheal area, which may cause serious safety hazards. At the same time, the actual pressure borne by the wound is often insufficient, the hemostasis effect is not ideal, and the frequent slippage of the sandbag can easily cause delayed pocket hematoma.

[0005] In addition, the arm on the surgical side of the patient is prone to involuntary forceful abduction after operation, which may pull the incision and cause the wound to dehisce. In order to prevent the sandbag from slipping, multiple adhesive tapes are usually used to fix the sandbag on the surface of the patient's skin in clinical practice, which can easily cause damage to the skin. Since different patients repeatedly use the same sandbag, it is not easy to thoroughly clean the sandbag once it is contaminated with blood and other contaminants, and there is a risk of cross infection. During the compression hemostasis process, medical staff also need to frequently check and adjust the position of the sandbag, further increasing the nursing workload.

[0006] In summary, the existing sandbag compression hemostasis method after permanent pacemaker implantation has shortcomings in terms of pressure adjustment capability, stability, safety, patient comfort and efficiency of medical staff, and improvement of the postoperative incision compression hemostasis method is urgently needed. SUMMARY

[0007] The application aims at solving the problems in the prior art and provides an intelligent air bag pressurization device used after pacemaker implantation.

[0008] To achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0009] An intelligent air bag pressurization device used after pacemaker implantation comprises a shell, and the device comprises a pressurization fixing assembly and a battery power supply system, a central control unit, a pressure acquisition module, a touch screen display and operation system and a pressure generator arranged on the shell.

[0010] Preferably, the battery power supply system comprises a switch and a power supply seat arranged on the shell, and is used for providing power for the device.

[0011] Preferably, the pressure acquisition module comprises a pressure sensor used for acquiring pressure data in the pressurization air bag, and the pressure acquisition module transmits the data to the central control unit.

[0012] Preferably, the pressure generator is connected with the inside of the pressurization air bag through a gas pump connecting pipe, and an electromagnetic valve is arranged between the pressure generator and the gas pump connecting pipe.

[0013] Preferably, the central control unit comprises a main control board, which is used for processing the pressure data acquired by the pressure acquisition module and controlling the pressure generator according to preset parameters to adjust the pressure in the pressurization air bag.

[0014] Preferably, the central control unit adopts a 32-bit ARM kernel microcontroller (MCU) to process data, thereby ensuring accurate control of the air bag pressure.

[0015] Preferably, the touch screen display and operation system comprises a touch screen, which is used for displaying the pressure data acquired by the pressure acquisition module.

[0016] Preferably, the device further comprises an alarm mechanism, which is used for issuing an alarm when the pressure data acquired by the pressure acquisition module exceeds a preset pressure range.

[0017] The application has the following beneficial effects:

[0018] The intelligent air bag pressurization device used after pacemaker implantation can display the pressure value in the pressurization air bag in real time through the touch screen, and can stably control the pressure applied to the wound during the patient's breathing and chest fluctuation, thereby being beneficial to maintaining the relative constancy of the pressure at the wound and improving the reliability of compression hemostasis.

[0019] The shoulder and arm fixing belt in the pressurizing fixing assembly can limit the range of motion of the upper limb on the surgical side of the patient, so that the upper limb on the surgical side is kept within a safe range of motion, avoiding pulling on the postoperative wound caused by the arm being involuntarily abducted or force, and being beneficial to the stable healing of the wound.

[0020] By arranging the touch screen display and operation system in the device, medical staff can set the pressure parameters according to the postoperative condition of the patient, the device can automatically run according to the set parameters after starting, and the buzzer is prompted after running, reducing the frequency of manual intervention and improving the work efficiency of medical staff.

[0021] When the device is applied in clinical medical practice teaching and postoperative care after permanent pacemaker implantation, the operation mode is relatively simple, the use process is convenient and fast, the stable control of the wound pressurization process can be realized, and the scientific, accurate and reliable pressurization hemostasis effect can be achieved.

[0022] By reasonably setting the interval time of pressure change and the pressure adjustment process, the continuous compression strength on the puncture point and the wound site can be reduced, the safety of the patient is improved, and the work burden of medical staff is reduced while ensuring the hemostasis effect.

[0023] In addition, the alarm mechanism arranged in the device can prompt the patient and medical staff when the pressure is abnormal, which is helpful to timely find the situation of insufficient pressure and avoid adverse consequences caused by abnormal pressure.

[0024] When the pressurized air bag is used for compression hemostasis of the wound, the contact area of the air bag and the skin is large, the pressure acting on the skin surface can be effectively dispersed, the pressure injury to the skin is reduced, and the comfort of the patient is improved. By fixing the shoulder and arm on the surgical side, the air bag compression site is more stable, and the patient's involuntary upper arm abduction action is limited, which is helpful to avoid the adverse effects on respiration and incision healing, thereby further improving the overall comfort of the patient.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0029] In one embodiment, referring to Figs. 1-2 , an intelligent airbag pressurization device after pacemaker implantation includes a shell 1, the device includes a pressurization fixing assembly 14 and a battery power supply system, a central control unit, a pressure acquisition module 10, a touch screen display and operation system and a pressure generator 11 arranged on the shell 1; the pressurization fixing assembly 14 includes an adjustable shoulder fixing belt 3, a limiting arm fixing belt 2, an adjustable chest fixing belt 4 and a pressurization airbag 5.

[0030] As a preferred embodiment of the present application, the pressurization fixing assembly 14 is used to fix the airbag and limit the range of motion of the arm on the operation side.

[0031] As a preferred embodiment of the present application, the pressurization fixing assembly 14 is a vest type binding belt device.

[0032] As a preferred embodiment of the present application, the battery power supply system includes a switch 7 and a power supply seat 8 arranged on the shell 1, which is used to provide power for the device.

[0033] As a preferred embodiment of the present application, the pressure acquisition module 10 includes a pressure sensor used to acquire pressure data in the pressurization airbag 5, and the pressure acquisition module 10 transmits the data to the central control unit.

[0034] As a preferred embodiment of the present application, in order to realize accurate control of the pressure in the pressurization airbag 5, the central control unit converts the relationship between the air pressure in the pressurization airbag 5 and the pressure acting on the postoperative wound after receiving the pressure data acquired by the pressure acquisition module 10. Specifically, the air pressure in the pressurization airbag 5 is used to generate a compression effect on the wound, and the bearing capacity generated thereby can be calculated by the relationship between the gas pressure and the effective bearing area.

[0035] In the calculation process, the force F generated in the pressurization airbag 5 satisfies the following relationship between the internal air pressure P of the airbag and the effective bearing area A: F = P × A, wherein F is the force generated by the pressurization airbag 5, the unit is Newton (N); P is the air pressure inside the pressurization airbag 5, the unit is Pascal (Pa); A is the effective bearing area formed by the contact between the pressurization airbag 5 and the human body, the unit is square meter (m²).

[0036] Since the clinical use usually takes kilogram-force as the reference unit of pressure, for the convenience of medical staff to understand and set parameters, the force calculated above needs to be converted from Newton unit to kilogram-force unit. The conversion relationship between Newton and kilogram-force is: 1 kgf = 9.80665 N, therefore, the kilogram-force value F_kgf generated by the pressurized air bag can be obtained by the following formula: F_kgf = F / 9.80665.

[0037] The central control unit calculates and processes the air pressure data collected by the pressure collection module 10 based on the conversion relationship above, and controls the working state of the pressure generator in combination with the preset parameters, so that the pressure applied to the postoperative wound by the pressurized air bag 5 is kept within the set range, realizing the stable and adjustable pressurization of the wound.

[0038] As a preferred embodiment of the present application, the pressure generator 11 is connected to the inside of the pressurized air bag 5 through the air pump connection pipe 6, and an electromagnetic valve 12 is arranged between the pressure generator 11 and the air pump connection pipe 6.

[0039] As a preferred embodiment of the present application, the central control unit includes a main control board 9 for processing the pressure data collected by the pressure collection module 10 and controlling the pressure generator 11 according to the preset parameters to adjust the pressure in the pressurized air bag 5.

[0040] As a preferred embodiment of the present application, the central control unit uses a 32-bit ARM core microcontroller (MCU) for data processing, and the air pressure sensor in the pressure collection module is used to collect the air pressure value in the pressurized air bag 5 in real time and transmit the collected air pressure data to the central control unit. The central control unit processes the collected air pressure value and converts it into the kilogram-force value equivalent to the force acting on the postoperative wound of the patient.

[0041] The central control unit controls the working state of the pressure generator according to the pressure value converted above. When the pressure value is lower than the preset range, the central control unit controls the air pump in the pressure generator to open and pressurize the pressurized air bag 5; when the pressure value is higher than the preset range, the central control unit controls the electromagnetic valve arranged in the pressure generator to open and depressurize the pressurized air bag 5. By controlling the running state of the air pump and the opening and closing state of the electromagnetic valve, the pressure in the pressurized air bag 5 is kept within the required range, thereby realizing the accurate control of the air bag pressure.

[0042] As a preferred embodiment of the present application, the touch screen display and operation system comprises a touch screen 13 for displaying the pressure data collected by the pressure collection module. The touch screen 13 adopts a touch operation mode and can display the pressure value in the pressurized air bag 5 in real time. The medical staff can set the operation parameters of the device through the touch screen 13, including the initial pressure value when the device starts, the interval time of pressure change, the pressure reduction value, and the operation time of the device.

[0043] After the above-mentioned parameter setting is completed, the device starts and automatically operates according to the set parameters, and adjusts the pressure in the pressurized air bag 5 according to the preset pressure change rule during the operation. When the device operation ends, the buzzer in the alarm mechanism issues a prompt to remind the medical staff that the device operation state has ended.

[0044] As a preferred embodiment of the present application, the device further comprises an alarm mechanism for issuing an alarm when the pressure data collected by the pressure collection module 10 exceeds the preset pressure range.

[0045] The present application uses a chest-like binding belt device to fix the postoperative wound of the patient, sets a pressurized air bag 5 at the surgical wound, and controls the pressure generator 11 through an embedded microcontroller. Through the coordinated control of the air pump and the electromagnetic valve 12, the pressure in the pressurized air bag 5 can be adjusted in real time and accurately, so that the pressure applied to the wound is kept within a stable range, thereby facilitating the acceleration of wound healing.

[0046] In the early postoperative period, a large pressure needs to be applied to the wound to ensure that the wound does not bleed, for example, a pressure equivalent to about 1 kg; as time goes by, the wound gradually heals, and the required pressure also gradually decreases accordingly. In the traditional sandbag compression method, pressure adjustment is usually achieved by replacing sandbags of different weights, for example, replacing a 1 kg sandbag with a 0.5 kg sandbag. During the replacement of the sandbag, the sandbag needs to be temporarily removed from the wound, which can easily cause the risk of bleeding. In the present scheme, the pressure in the pressurized air bag 5 is automatically adjusted, and the pressure applied to the wound can be gradually reduced according to the pre-set parameters. During the entire adjustment process, the pressurized air bag 5 does not need to leave the patient's body, thereby effectively reducing the risk of wound bleeding.

[0047] In addition, the binding belt device also has the function of limiting the range of motion of the patient's operative arm, so that the operative arm can only move slightly, avoiding the arm from being involuntarily abducted or exerting force on the wound to cause traction, thereby further reducing the adverse effects on wound healing.

[0048] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
