Description

Technical Field

[0001] This application relates to medical assistive devices, specifically to a device for preventing acquired pressure injury during occipital surgery and its method of use. Background Technology

[0002] Intraoperative acquired pressure injury refers to pressure injury that occurs to a patient during the course of surgery. Pressure injuries are localized injuries to the skin and / or subcutaneous tissue caused by pressure or pressure combined with shear forces, usually occurring at the depressor bony prominence, and may also be related to medical devices or other objects.

[0003] Pressure injuries are localized injuries to the skin or subcutaneous soft tissue, typically occurring at bony prominences or sites of pressure from medical devices or other instruments. In 2016, the National Pressure Ulcer Advisory Panel (NPUAP) in the United States changed the term "pressure ulcer" to "pressure injury." Pressure injuries not only cause significant physical and psychological suffering for patients and affect postoperative recovery, but also increase medical costs for patients and society, and can even lead to medical disputes. Therefore, pressure injuries have been identified as a sensitive indicator for evaluating the quality of care by researchers both domestically and internationally. Currently, the occurrence of pressure injuries is believed to depend on two factors: pressure and tissue tolerance. Infants and young children, whose thermoregulatory centers are not yet fully developed and whose sweat glands and circulatory systems are still developing, have lower skin tissue tolerance than adults and are more susceptible to the influence of the peripheral microenvironment, making them a high-risk group for pressure injuries. For infants who undergo liver transplantation, the risk of postoperative occipital pressure injury is further increased due to factors such as prolonged surgery time, hypothermia caused by freezing of the transplanted liver, and the relatively large proportion of head weight in infants. Therefore, it is an urgent problem to investigate the risk factors for postoperative occipital pressure injury in liver transplant recipients and to develop corresponding preventive measures.

[0004] Hypothermia, defined as a core body temperature below 36°C, is one of the most common complications of surgery.

[0005] Surgical positioning adjustment refers to local decompression care implemented during surgery on areas of pressure caused by the patient's position, provided that the surgery is permitted.

[0006] Common pressure points in surgical positions include the occipital region and the scapular region. The pressure points in the occipital region and the scapular region are the pressure points in both shoulders after the patient is repositioned during surgery.

[0007] Current technologies for treating acquired pressure injuries of the occipital region rely on manual intervention before, during, and after surgery, lacking products capable of automated detection and intervention. Furthermore, existing interventions are systemic, lacking localized intervention measures. Summary of the Invention

[0008] To address the problems of existing technologies, this invention provides a device and its method for preventing acquired pressure injuries of the occipital region during surgery. It employs an occipital support rod assembly to achieve multi-point support, reducing and dispersing pressure at the posterior occipital depressor. The pressure duration at the pressure-bearing area can be automatically controlled, with alternating pressure application. The duration of support at the posterior occipital depressor and the duration of pressure dispersion at the support points are both controllable, allowing for alternating cyclical support that can be synchronous or asynchronous. The gaps between the alternating support points are used to detect the temperature and humidity of the pressure-bearing area, and a flowing airflow (heated air) is introduced to create circulation and balance the temperature and humidity in the gaps.

[0009] The technical solution of the present invention is: a device for preventing intraoperative pressure injury of the occipital region, comprising a head support and a neck support;

[0010] The head support includes a headrest body, and a headrest support rod assembly is provided on the headrest body at a position for contact with the back of the patient's head.

[0011] The occipital support rod assembly is circular in shape, with several support rods evenly arranged on multiple concentric circles centered on the center point of the circle. When all the support rods are retracted, their top ends combine to form an arc-shaped support groove for supporting the back of the patient's head. The support rods can automatically move up and down and extend and retract, and adjacent support rods are fixedly connected by support rod fixing clips.

[0012] The bottom of the occipital support rod assembly is equipped with an electrical control circuit board. The bottom of each support rod is electrically connected to an electrical terminal on the electrical control circuit board. The electrical control circuit board is electrically connected to the intelligent control chip and the control circuit board. Through the intelligent control of the intelligent control chip and the control circuit board, the support rods in the occipital support rod assembly can be set into multiple sets of alternating support layouts, and it can be ensured that when each set of support rods is in use, the patient's back of the head is evenly stressed.

[0013] Furthermore, the support rod includes a support rod base, a support rod cylinder, a telescopic rod, a telescopic rod support bracket, an upper adjustment control valve for the support rod, and a lower adjustment control valve for the support rod;

[0014] The support rod base is connected to the power control circuit board. The support rod cylinder is fixedly connected to the support rod base. The telescopic rod is telescopically mounted inside the support rod cylinder. The telescopic rod support bracket is rotatably mounted on the top of the telescopic rod. An upper and lower adjustment control valve are mounted on the support rod cylinder. Adjusting the air inlet and outlet states of the upper and lower adjustment control valves controls the upward extension or downward retraction of the support rod. Preferably, the upward extension height of the support rod is 0.5-5mm. More preferably, the upward extension height is 2-3mm.

[0015] The head support is equipped with an air inlet and an air outlet on the side opposite to the neck support. An air inlet control valve is installed at the air inlet, and an air outlet control valve is installed at the air outlet. All support rods have upper adjustment control valves connected to the upper adjustment control valve gas connection pipe via gas pipes, and all support rods have lower adjustment control valves connected to the lower adjustment control valve gas connection pipe via gas pipes. The air outlet of the air inlet has two paths: one path connects to the upper adjustment control valve gas connection pipe via the support rod lifting air inlet control valve, and the other path connects to the lower adjustment control valve gas connection pipe via the support rod lowering air inlet control valve. The air outlet of the air outlet is collected from two paths: one path connects to the upper adjustment control valve gas connection pipe via the support rod lowering exhaust control valve, and the other path connects to the lower adjustment control valve gas connection pipe via the support rod lifting exhaust control valve.

[0016] Furthermore, it also includes temperature and humidity sensor components and temperature and humidity control components;

[0017] The temperature and humidity sensor assembly includes multiple temperature and humidity sensors evenly arranged in the pillow support rod assembly. Each temperature and humidity sensor is electrically connected to the power terminal on the power control circuit board, and transmits the temperature and humidity detected by the temperature and humidity sensor to the intelligent control chip.

[0018] The temperature and humidity regulating assembly includes a temperature and humidity regulating gas pipeline that surrounds each support rod in the pillow support rod assembly. Multiple temperature and humidity regulating gas outlets are evenly opened on the temperature and humidity regulating gas pipeline. The air inlet of the temperature and humidity regulating gas pipeline is connected to the air inlet through a temperature and humidity regulating air inlet pipeline. An air heater is provided on the temperature and humidity regulating air inlet pipeline.

[0019] When the temperature and humidity value detected by the temperature and humidity sensor is greater than or equal to the maximum set temperature and humidity value, the temperature and humidity adjustment component is activated to adjust the temperature and humidity value through gas flow; when the temperature and humidity value detected by the temperature and humidity sensor is less than or equal to the minimum set temperature and humidity value, the temperature and humidity adjustment component is activated to heat the gas through the air heater and adjust the temperature and humidity value through gas flow.

[0020] Furthermore, the time during which the temperature and humidity sensor detects a temperature and humidity value greater than or equal to the highest set temperature and humidity value or less than or equal to the lowest set temperature and humidity value is defined as the first measurement time. The alternation time of the support rods within the pillow support rod assembly is defined as the second measurement time, typically set to 30-60 minutes. When the first measurement time is less than the second measurement time, the first measurement time is set as the new alternation time of the support rods within the pillow support rod assembly.

[0021] Furthermore, the multiple alternating support layout can be a two-group, three-group, or four-group alternating support layout; the total pressure that each support rod can support is greater than or equal to the total pressure of the required support. Generally, the standard single-point support pressure is 4-4.7 kPa.

[0022] Furthermore, a pillow cover is provided on the top of the pillow support rod assembly, and the pillow cover is fixed to the headrest body by a pillow cover pressure ring.

[0023] Furthermore, the neck support is used to assist in supporting the patient's neck and shoulder blades, and is an inflatable airbag structure.

[0024] Furthermore, a display screen is also provided on the side of the head support facing away from the neck support.

[0025] Furthermore, a control panel is provided on the side of the head support facing away from the neck support. The control panel is equipped with a power switch, a manual / automatic switching button, a pressure adjustment button, and a temperature control adjustment button.

[0026] This invention also provides a method of using a device for preventing acquired pressure injury during occipital surgery. When the manual / automatic switch button is switched to automatic mode, the specific steps are as follows:

[0027] Step 1: Detect the total pressure of the required support structure using the pillow support rod assembly. Select the number of support rods based on the total pressure. Let the total pressure of the required support structure be P1, and the set total pressure of all support rods be P2. If P1 is less than or equal to half of P2, select a support rod quantity of half the total number of support rods. If P1 is less than or equal to one-third of P2, select a support rod quantity of one-third the total number of support rods. If P1 is less than or equal to one-quarter of P2, select a support rod quantity of one-quarter the total number of support rods.

[0028] Step 2: Select the alternating support layout based on the number of support rods. When the number of support rods is half of the total number of support rods, two sets of alternating support layouts will be automatically selected; when the number of support rods is one-third of the total number of support rods, three sets of alternating support layouts will be automatically selected; when the number of support rods is one-quarter of the total number of support rods, four sets of alternating support layouts will be automatically selected.

[0029] Step 3: Activate alternating support according to the set alternating time of the support rods in the pillow support rod assembly; each time the alternating support changes, adjust the air intake and exhaust control valves to control the next set of support rods to move upward to the support position, and then the current set of support rods moves downward to retract. At the same time, the temperature and humidity sensor assembly detects the temperature and humidity at each point, and the temperature and humidity adjustment assembly promotes the air flow between the support rods in the pillow support rod assembly.

[0030] Step 4: When the temperature and humidity value detected by the temperature and humidity sensor is greater than or equal to the maximum set temperature and humidity value, the temperature and humidity adjustment component is activated to adjust the temperature and humidity value through gas flow; when the temperature and humidity value detected by the temperature and humidity sensor is less than or equal to the minimum set temperature and humidity value, the temperature and humidity adjustment component is activated to heat the gas through the air heater and adjust the temperature and humidity value through gas flow; at the same time, the time when the temperature and humidity sensor detects a temperature and humidity value greater than or equal to the maximum set temperature and humidity value or less than or equal to the minimum set temperature and humidity value is set as the first measurement time, and the time when the support rods in the pillow support rod assembly alternate is set as the second measurement time. When the first measurement time is less than the second measurement time, the first measurement time is set as the new time when the support rods in the pillow support rod assembly alternate.

[0031] When the manual / automatic switch button is switched to manual mode, the pressure adjustment button is used to select the number of support rods and the corresponding alternating support layout, and the temperature control adjustment button is used to select the working interval of the temperature and humidity control component.

[0032] The beneficial effects of this invention are: it provides a device and method for preventing postoperative occipital pressure injury.

[0033] 1. Multiple rings of support are added around the core support area to increase support and reduce pressure in the core area;

[0034] 2. The core area and the outer perimeter are supported by multiple points.

[0035] 3. Grouping is based on the principle that the patient's back of the head is evenly stressed when supported by each set of support rods. At least two sets of support rods are used alternately at regular intervals each time. The cycle is cyclical and the support time is controllable. Tissue tolerance is usually affected by internal factors (patient's own factors) and external factors (microenvironment).

[0036] 4. Temperature and humidity sensors are arranged in multiple rings around the core area and the outer perimeter to monitor changes in temperature and humidity within the area;

[0037] 5. Multiple airflow channels and air outlets are set up in the core area and outer perimeter – the gaps between each support point;

[0038] 6. Heated airflow – adjustments can be made based on regional temperature and humidity monitoring results (microenvironmental regulation). Attached Figure Description

Detailed Implementation

[0056] The present invention will now be further described with reference to the accompanying drawings.

[0057] Pressure injuries occur because they depend on two factors: pressure and tissue tolerance. The pressure factor depends on the intensity and duration of the pressure. Tissue tolerance is typically influenced by both intrinsic factors (patient-related factors) and extrinsic factors (microenvironment).

[0058] 1. Pressure Factor – Compressive Strength:

[0059] a) The pressure mainly comes from the weight of the patient's head, shoulders and back, especially the hard points at the bony prominences (back of the head, both scapulae) that cause damage to the compressed tissues from the inside out.

[0060] b) Solution: Reduce and distribute pressure on the depressor points (posterior occipital region, bilateral scapulae) (multi-point support).

[0061] 2. Stress Factors – Duration:

[0062] a) The pressure time of the pressure-bearing part can be automatically controlled and alternately pressure-bearing (i.e., the duration of each support point is controllable and each group of support points can alternately support).

[0063] b) The duration of support points at the bony depressor points (posterior occipital region, bilateral scapulae) and the duration of support points at the dispersed support points can be controlled, with alternating cyclical support, and can be synchronous or asynchronous.

[0064] 2. Tissue tolerance – intrinsic factors:

[0065] a) Preoperative assessment is required due to the patient's own factors to determine the risk level.

[0066] b) Set adjustment data for stress factors based on risk level.

[0067] 3. Tissue tolerance – External factors (microenvironment):

[0068] Currently, there is still a lack of a universally accepted concept of the microenvironment. In 1976, nursing scholar Roaf first proposed the concept of the microenvironment, arguing that maintaining blood circulation, avoiding prolonged and continuous pressure, avoiding extreme temperature and humidity, maintaining a favorable microenvironment, and avoiding infection and fluid irritation are important factors in preventing pressure injuries. He defined the microenvironment as skin temperature, humidity, and airflow. The microenvironment mainly encompasses two aspects: the temperature and humidity of the skin surface, and airflow ultimately affects the temperature and humidity of the skin surface. Excessive temperature and humidity lead to localized skin dampness, increased metabolism, and decreased tolerance; excessively low temperature and humidity result in dry, fragile skin, slowed blood circulation, and loss of the protective layer, thus leading to pressure injuries.

[0069] a) Microenvironment – ​​Temperature.

[0070] b) Microenvironment – ​​Humidity.

[0071] c) Microenvironment - air flow: The temperature and humidity of the pressure-bearing part are detected by the gap of the alternating support points and a flowing air flow (the air can be heated) is added to form a flow circulation and balance the temperature and humidity of the gap part.

[0072] 3. Technical Structure Design Scheme

[0073] like Figure 1 , 2 As shown, a device for preventing acquired pressure injury during occipital surgery includes a head support and a neck support. The neck support is used to assist in supporting the patient's neck and shoulders, and is an inflatable airbag structure.

[0074] The head support includes a headrest body, on which a occipital support rod assembly 1 is provided at a position for contacting the back of the patient's head. A pillow cover 6 is provided on the top of the pillow support rod assembly 1, and the pillow cover 6 is fixed to the headrest body by a pillow cover pressure ring 7.

[0075] like Figure 6 , 14As shown, the occipital support rod assembly 1 is circular in shape, with several support rods evenly arranged on multiple concentric circles centered on the center point of the circle. The tops of all the support rods are combined in the retracted state to form an arc-shaped support groove for supporting the back of the patient's head. The support rods can automatically move up and down and extend and retract, and adjacent support rods are fixedly connected by support rod fixing clips 2.

[0076] like Figure 3 As shown, the bottom of the occipital support rod assembly 1 is provided with an electrical control circuit board 11. The bottom of each support rod is electrically connected to the electrical terminal on the electrical control circuit board 11. The electrical control circuit board 11 is electrically connected to the intelligent control chip 8 and the control circuit board 9. Through the intelligent control of the intelligent control chip 8 and the control circuit board 9, the support rods in the occipital support rod assembly 1 can be set into multiple alternating support layouts, ensuring that the patient's back of the head is evenly stressed when each set of support rods is in use. The multiple alternating support layouts are as follows: Figure 8 The two sets of alternating support layouts shown are as follows: Figure 9 The diagram shows either three or four alternating support layouts. Each support rod can withstand a total pressure greater than or equal to the total pressure of the object being supported. The standard single-point support pressure is typically 4-4.7 kPa.

[0077] like Figure 10 , 11 As shown, the support rod includes a support rod base 101, a support rod cylinder 102, a telescopic rod 103, a telescopic rod support bracket 104, an upper adjustment control valve 105, and a lower adjustment control valve 106. In this embodiment, the support rod base has a diameter of approximately 10mm, the support rod cylinder has a diameter of approximately 6mm, and the telescopic rod has a diameter of approximately 4mm. The support rod base 101 is connected to the power control circuit board 11. The support rod cylinder 102 is fixedly connected to the support rod base 101. The telescopic rod 103 is telescopically disposed within the support rod cylinder 102. The telescopic rod support bracket 104 is rotatably disposed on the top of the telescopic rod 103. The upper adjustment control valve 105 and the lower adjustment control valve 106 are disposed on the support rod cylinder 102. By adjusting the air inlet and outlet states of the upper and lower adjustment control valves, the support rod is controlled to extend upwards or retract downwards. In this embodiment, the height to which the support rod extends upward can be set to 0.5-5mm according to the patient's needs. In a preferred embodiment, the height to which the support rod extends upward can be set to 2-3mm according to the patient's needs. An air inlet 109 and an air outlet 107 are provided on the side of the head support facing away from the neck support. An air inlet control valve 110 is provided at the air inlet 109, and an air outlet control valve 108 is provided at the air outlet 107. Figure 7 , 13As shown, the upper regulating control valve 105 of all support rods is connected to the upper regulating control valve gas connection pipe 111 via a gas pipe, and the lower regulating control valve 106 of all support rods is connected to the lower regulating control valve gas connection pipe 112 via a gas pipe. The air outlet of the air inlet 109 is divided into two paths: one path is connected to the upper regulating control valve gas connection pipe 111 via the support rod lifting air inlet control valve 114, and the other path is connected to the lower regulating control valve gas connection pipe 112 via the support rod lowering air inlet control valve 116. The air outlet of the exhaust nozzle 107 is collected from two paths: one path is connected to the upper regulating control valve gas connection pipe 111 via the support rod lowering exhaust control valve 113, and the other path is connected to the lower regulating control valve gas connection pipe 112 via the support rod lifting exhaust control valve 115. When a portion of the support rod needs to extend upwards, open the support rod lifting intake control valve 114 and the support rod lifting exhaust control valve 115, and close the support rod lowering intake control valve 116 and the support rod lowering exhaust control valve 113. Control the upper adjustment control valve 105 of the support rod corresponding to the support rod that needs to extend upwards to allow air in and the lower adjustment control valve 106 of the support rod to exhaust air, thus slowly raising the telescopic rod corresponding to the support rod that needs to extend upwards to extend upwards. When a portion of the support rod needs to retract downwards, open the lower intake control valve 116 and the lower exhaust control valve 113 of the support rod, and close the lifting intake control valve 114 and the lifting exhaust control valve 115. Control the lower adjustment control valve 106 of the support rod corresponding to the support rod that needs to retract downwards to allow air in and the upper adjustment control valve 105 of the support rod to exhaust air, thus slowly retracting the telescopic rod corresponding to the support rod that needs to retract downwards to retract downwards.

[0078] Devices for preventing acquired pressure injuries during occipital surgery also include, for example... Figure 5 The temperature and humidity sensor assembly 4 shown and as follows Figure 4 , 12 The temperature and humidity control component 3 is shown.

[0079] The temperature and humidity sensor assembly 4 includes multiple temperature and humidity sensors evenly arranged in the pillow support rod assembly 1. Each temperature and humidity sensor is electrically connected to the power terminal on the power control circuit board 11, and transmits the temperature and humidity detected by the temperature and humidity sensor to the intelligent control chip 8.

[0080] The temperature and humidity regulating component 3 includes a temperature and humidity regulating gas pipeline 302 surrounding the support rods within the pillow support rod assembly 1. The temperature and humidity regulating gas pipeline 302 is provided with a plurality of temperature and humidity regulating air outlets 303 evenly distributed on it. The air inlet of the temperature and humidity regulating gas pipeline 302 is connected to the air inlet 109 through a temperature and humidity regulating air inlet pipeline, and an air heater 301 is provided on the temperature and humidity regulating air inlet pipeline.

[0081] When the temperature and humidity value detected by the temperature and humidity sensor is greater than or equal to the maximum set temperature and humidity value, the temperature and humidity regulating component is activated to adjust the temperature and humidity value through gas flow. When the temperature and humidity value detected by the temperature and humidity sensor is less than or equal to the minimum set temperature and humidity value, the temperature and humidity regulating component is activated to heat the gas through an air heater and adjust the temperature and humidity value through gas flow. More preferably, the time during which the temperature and humidity sensor detects a temperature and humidity value greater than or equal to the maximum set temperature and humidity value or less than or equal to the minimum set temperature and humidity value is defined as the first measurement time, and the alternation time of the support rods within the pillow support rod assembly is defined as the second measurement time, typically set to 30-60 minutes. When the first measurement time is less than the second measurement time, the first measurement time is set as the new alternation time of the support rods within the pillow support rod assembly.

[0082] like Figure 15 As shown, a display screen 12 is also provided on the side of the head support facing away from the neck support. A control panel is also provided on the side of the head support facing away from the neck support, and the control panel is provided with a power switch 14, a manual / automatic switch 16, a pressure adjustment button 13, and a temperature control adjustment button 15.

[0083] When the manual / automatic switch button 16 is switched to automatic mode, the specific steps are as follows:

[0084] Step 1: The pillow support rod assembly 1 detects the total pressure of the required support and selects the number of support rods based on this total pressure. Let the total pressure of the required support be P1, and the set total pressure of all support rods be P2. If P1 is less than or equal to half of P2, select a support rod quantity of half the total number of support rods. If P1 is less than or equal to one-third of P2, select a support rod quantity of one-third the total number of support rods. If P1 is less than or equal to one-quarter of P2, select a support rod quantity of one-quarter the total number of support rods.

[0085] Step 2: Select the alternating support layout based on the number of support rods. When the number of support rods is half of the total number of support rods, two sets of alternating support layouts will be automatically selected. When the number of support rods is one-third of the total number of support rods, three sets of alternating support layouts will be automatically selected. When the number of support rods is one-quarter of the total number of support rods, four sets of alternating support layouts will be automatically selected.

[0086] Step 3: Open the support rods in the pillow support rod assembly according to the set alternating time of the support rods. Figure 16The alternating support is shown. During each alternating support change, the air intake and exhaust control valves are adjusted to control the next set of support rods to move upwards to the support position, and then the current set of support rods moves downwards to retract. At the same time, the temperature and humidity sensor assembly detects the temperature and humidity at each point, and the temperature and humidity adjustment assembly promotes airflow between the support rods in the pillow support rod assembly.

[0087] Step 4: When the temperature and humidity value detected by the temperature and humidity sensor is greater than or equal to the maximum set temperature and humidity value, the temperature and humidity regulating component is activated to adjust the temperature and humidity value through gas flow. When the temperature and humidity value detected by the temperature and humidity sensor is less than or equal to the minimum set temperature and humidity value, the temperature and humidity regulating component is activated to heat the gas through the air heater and adjust the temperature and humidity value through gas flow. Simultaneously, the time during which the temperature and humidity sensor detects a temperature and humidity value greater than or equal to the maximum set temperature and humidity value or less than or equal to the minimum set temperature and humidity value is defined as the first measurement time, and the alternation time of the support rods within the pillow support rod assembly is defined as the second measurement time. When the first measurement time is less than the second measurement time, the first measurement time is set as the new alternation time of the support rods within the pillow support rod assembly. When the manual / automatic switch button 16 is switched to manual mode, the pressure adjustment button 13 selects the number of support rods and the corresponding alternating support layout, and the temperature control adjustment button 15 selects the working interval time of the temperature and humidity regulating component.

[0088] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
