Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to an intelligent skin flap microcirculation detection compression airbag. Background Art

[0002] In clinical practice, conventional postoperative bandaging is generally used to compress and stop bleeding in the flap transfer area. Due to the large variability of body structure and shape, it is difficult for fixed conventional postoperative bandaging to produce sufficient hemostatic pressure in the flap transfer area. Insufficient compression can lead to a higher risk of local flap hematoma. However, if compression is simply performed using a fixed device such as an airbag, the microcirculation of the local flap will be damaged, leading to a series of clinical problems such as flap necrosis and pressure sores.

[0003] However, due to individual differences, it is difficult to give a constant and suitable pressure to effectively prevent the occurrence of hematoma. Therefore, it is necessary to measure the temperature and hemostatic pressure of the local skin flap to maximize the hemostatic pressure without blocking the microcirculation. At present, in order to achieve the above-mentioned measurement and adjustment of hemostatic pressure, medical staff need to perform instrument testing repeatedly. This method will greatly increase the labor of medical staff, and it is impossible to achieve real-time online monitoring. There is still the problem that the hemostatic pressure cannot be adjusted in real time.

[0004] Based on this, it is necessary to develop an intelligent skin flap microcirculation detection compression airbag to overcome the above technical problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent skin flap microcirculation detection compression airbag, which effectively overcomes the defects of the prior art.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a wire tube connected to the bladder is arranged side by side at the medium injection tube, and the pressure sensor is connected to the processor via a line passing through the wire tube.

[0010] Furthermore, a first control valve is provided at the above-mentioned joint.

[0011] Furthermore, the joint is sealed with a puncturable rubber stopper.

[0012] Furthermore, the processor is provided with a communication module, and the communication module is connected to a backend terminal via a network.

[0013] Furthermore, the above-mentioned background terminal is a host computer, mobile phone or tablet.

[0014] Furthermore, temperature sensors are evenly dispersed and embedded on the surface of the capsule, and the temperature sensors are connected to the processor circuit.

[0015] Furthermore, the joint is connected with a tee, one of the interfaces of the tee is connected to the medium injection system through a pipeline, and the other interface of the tee is provided with a second control valve.

[0016] Furthermore, the medium injection system includes an air pump or a liquid pump, the outlet of the air pump or the liquid pump is connected to one of the interfaces of the three-way valve through a first pipeline, and a third control valve is provided on the pipeline.

[0017] Furthermore, the above-mentioned bladder body is a strip-shaped bladder body, and the surfaces of both ends thereof are provided with Velcro tapes that can adhere to each other, or the two ends of the above-mentioned bladder body are respectively connected to elastic bandages.

[0018] The beneficial effects of the present invention are: the structural design is simple and reasonable, and it can monitor the pressure changes in real time during use, especially when implanted under the patient's tissue, and adjust the pressure in the balloon according to the pressure changes, so as to achieve the purpose of adjusting the balloon according to the difference in individual morphology, so that the balloon has sufficient pressure to effectively prevent the formation of hematoma, and will not cause problems such as flap necrosis and pressure sores due to excessive compression that damages the blood circulation of the flap.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Example 1

[0029] like Figure 1 As shown, the intelligent skin flap microcirculation detection compression airbag of this embodiment includes a balloon body 1, and pressure sensors 2 are evenly dispersed and embedded on the surface of the balloon body. The balloon body 1 is connected to a medium injection tube 11 connected to its inner cavity, and a joint 12 is provided at the end of the medium injection tube 11. The pressure sensor 2 is connected to a processor;

[0030] The processor adopts a wired connection mode. Specifically, a wire tube 13 connected to the bladder 1 is arranged side by side at the medium injection pipe 11. The pressure sensor is connected to the processor (denoted by A in the figure) via a line passing through the wire tube 13.

[0031] In this embodiment, when used, taking external ear plastic surgery as an example, the first-stage operation needs to implant the intelligent skin flap microcirculation detection compression airbag of this embodiment in the mastoid area behind the patient's ear, and then inject the medium into the airbag 1 for expansion. After the operation, the pressure sensor 2 monitors the pressure data of the local skin flap in real time. Once the pressure is lower than the "low pressure" parameter, the medical staff immediately injects the medium into the capsule 1 to increase the pressure. If the pressure in the capsule 1 reaches or exceeds the "high pressure" parameter, the medical staff immediately extracts the medium from the capsule 1 and adjusts the pressure in the entire capsule 1, so that the pressure of the airbag can be adjusted in time under the real-time detection guidance of the pressure sensor 2, ensuring that the entire airbag can effectively stop bleeding without blocking microcirculation, avoiding the occurrence of complications such as skin flap necrosis and pressure sores. On the whole, it not only significantly reduces the risk of postoperative hematoma, but also promotes the survival rate of the skin flap by maintaining the normal microcirculation of the skin flap, and reduces the occurrence of postoperative complications. This intelligent compression adjustment technology can greatly improve the rehabilitation effect after surgery and has important clinical application prospects.

[0032] The core advantage of the intelligent flap microcirculation detection compression airbag of this embodiment is that it can use the pressure sensor 2 to provide real-time local flap pressure data feedback, realize personalized compression adjustment, maximize the postoperative flap survival rate, and reduce the occurrence of postoperative complications.

[0033] Based on Example 1, the joint 12 may have at least the following two structures combined to achieve pressure regulation:

[0034] 1) If Figure 1 As shown, a first control valve 121 is provided at the joint 12, and the opening and closing states can be adjusted by the first control valve 121. When the pressure needs to be adjusted, the equipment or instrument for medium injection or extraction can be connected at the joint 12, and the first control valve 121 can be opened to realize the operation of injection pressure increase or extraction pressure reduction.

[0035] 2) If Figure 2 As shown, the connector 12 is sealed with a puncturable rubber plug 122 .

[0036] In the solution 2), the entire compression airbag is equipped with a syringe for injecting or extracting a medium. The needle of the syringe is used to pierce the rubber stopper 122 to achieve the operation of injecting or extracting the medium into the balloon body 1.

[0037] In this embodiment, the processor is provided with a communication module, and the communication module is connected to the back-end terminal via a network. More specifically, the communication module can be designed as a wired communication module or a wireless communication module (both of which are products of the prior art and are integrated on the processor) according to actual needs. When a wired communication module is used, it is necessary to connect the back-end terminal (such as a computer) by wiring at the processor to achieve wired transmission; when a wireless communication module is used, a conventional Bluetooth or WIFI or 4G / 5G communication module on the market can be used to achieve network transmission with the back-end terminal (such as a mobile phone, tablet, etc.).

[0038] In this embodiment, the background terminal is a host computer, a mobile phone or a tablet, so as to ensure that the patient's local flap pressure data can be remotely fed back in real time.

[0039] Example 2

[0040] like Figure 3 As shown, on the basis of Example 1, temperature sensors 3 are evenly dispersed and embedded on the surface of the capsule 1, and the temperature sensors 3 are connected to the processor circuit.

[0041] In this embodiment, a temperature sensor 3 is also provided on the surface of the capsule 1, and the temperature sensor 3 is used to monitor the temperature information of the local skin flap in real time. If the temperature information is close to the normal value (human body temperature is used as the reference standard), it means that the blood circulation at the skin flap is normal. If the temperature is greatly different from the normal value (especially lower than the normal value), it means that the blood circulation at the skin flap is abnormal. At this time, timely processing is required (including pressure adjustment of the capsule 1).

[0042] Example 3

[0043] like Figure 4 As shown, based on Example 1 and Example 2, a tee 4 is connected to the joint 12, one interface of the tee 4 is connected to the medium injection system through a pipeline, and the other interface of the tee 4 is provided with a second control valve.

[0044] In this embodiment, a tee 4 is provided at the joint 12, that is, two interfaces are exposed, one of which is specifically connected to the medium injection system to pressurize the injected medium, and a second control valve is provided at the other interface. When the pressure is too high, the second control valve can be opened to discharge the medium and reduce the pressure. Of course, a medium discharge pipeline can also be detachably connected at the interface where the second control valve is provided.

[0045] In this embodiment, the medium injection system includes an air pump or a liquid pump, the outlet of which is connected to one of the interfaces of the tee 4 via a first pipeline, and a third control valve is provided on the pipeline. The medium is automatically injected via the air pump or the liquid pump.

[0046] Of course, the second control valve and the third control valve can be set as solenoid valves. After connecting the medium injection system, the local flap pressure value can be monitored in real time, and the pressure adjustment operation can be performed in real time according to the pressure value.

[0047] Example 4

[0048] like Figure 5 As shown, in this embodiment, the processor (indicated by a in the figure) can also be integrated in the independent cavity inside the capsule 1, with an independent power supply (can be equipped with wireless charging facilities or button batteries), and the connector 12 can be eliminated. Every time a pressurization or decompression operation is required, a syringe is used to puncture into the buried capsule 1 to inject or extract the medium. Of course, the capsule 1 will not leak at the puncture site of the syringe needle and will be closed automatically.

[0049] Example 5

[0050] like Figure 6As shown, based on embodiments 1, 2, 3, and 4, the above-mentioned capsule 1 is a strip-shaped capsule, and its two end surfaces are provided with Velcro that can adhere to each other, or the two ends of the above-mentioned capsule 1 are respectively connected with elastic bandages 14.

[0051] In this embodiment, the bag body 1 is an external hemostatic compression air bag, which is designed as a belt-shaped body and can be wrapped around the part of the patient's body that needs compression and hemostasis (such as arms, thighs, etc.). After wrapping, it can be fixed by Velcro at the end, or tied to the patient's body by elastic straps 14 at both ends.
