Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, relates to a body position drainage auxiliary device for lung ultrasound. BACKGROUND

[0002] Pulmonary infection is one of the common complications of severe bedridden patients, is an important factor for clinical off-line extubation, and is also the cause of patient death and functional recovery disorders. The incidence of neurosurgery combined with pulmonary infection is 27.5% to 67.3%, and the incidence is positively correlated with the severity of the disease. The incidence and hazard rate have a great influence on the treatment prognosis. The traditional body position drainage and back tapping method can achieve some drainage effect, but it cannot accurately distinguish the position of sputum accumulation and the more suitable effective drainage position, and the blind body position drainage not only increases the unknown risk factors of the patient, but also increases the load of nursing work. Studies have shown that clinical application of lung ultrasound can accurately distinguish the position of sputum accumulation and atelectasis, and can accurately take effective drainage position, so as to achieve the most effective drainage purpose and prevent and reduce the incidence of pulmonary infection and accumulation.

[0003] CN219332294U discloses a body position drainage sputum drainage auxiliary device, which comprises a first supporting pad. The first supporting pad is made of pressure-resistant material and comprises a front half-arch block and a rear half-arch block which are integrally formed. The upper surfaces of the front half-arch block and the rear half-arch block are connected to form an arc-shaped structure. The front-to-back length of the front half-arch block is greater than that of the rear half-arch block. The height of the upper surface of the front half-arch block gradually decreases from the rear to the front, and the height of the upper surface of the rear half-arch block gradually decreases from the front to the rear. The height of the front lower edge of the upper surface of the front half-arch block is lower than that of the rear lower edge of the upper surface of the rear half-arch block.

[0004] The first supporting pad of the patent is made of pressure-resistant material and is not easily deformed by pressure. It is stable and reliable in use. The patient's waist is located directly above the upper surface of the rear half-arch block, the patient's lungs are located directly above the upper surface of the front half-arch block, and the patient's head is located below the front lower edge of the upper surface of the front half-arch block. The patient's mouth is lower than the patient's lungs, which facilitates sputum drainage in the corresponding lateral position and improves the sputum drainage effect.

[0005] However, the body position drainage sputum drainage auxiliary device of the patent lacks a support structure specifically for fixing the patient's body position, which may cause the patient to feel tired when maintaining a single body position for a long time. Fatigue may cause the patient to deform the body position in the later stage of the treatment process, thereby affecting the effect of body position drainage. In addition, the patient may not be able to accurately follow the posture guidance provided by medical staff, resulting in inaccurate body position and affecting the effect of lung drainage.

[0006] In addition, on the one hand, due to the difference in understanding of those skilled in the art; on the other hand, because the applicant studied a large number of literatures and patents when making the utility model, but limited by the size and did not list all the details and contents in detail, but this is not the utility model does not have these features of the prior art, on the contrary, the utility model has all the characteristics of the prior art, and the applicant reserves the right to add related prior art in the background art. Content of the utility model

[0007] In view of the deficiencies of the prior art, the present application provides a body position drainage auxiliary device for lung ultrasound, which aims to solve one or more technical problems in the prior art.

[0008] The utility model relates to a kind of body position drainage auxiliary devices for lung ultrasound, including the upper limb part for carrying the upper half body of patient, the lower limb part for carrying the lower half body of patient and the ultrasonic equipment for detecting the sputum accumulation position of patient lung, the inside of upper limb part is respectively installed with several peltier according to the form and position corresponding to several standard drainage body position, several peltier corresponding to the same standard drainage body position can be connected in parallel or in series in the way of the same wire with the controller outside upper limb part electrically connected, controller can make all peltier connected with the wire enter or exit working state by the way of connecting or disconnecting any wire, wherein, controller passes through the wire corresponding to the drainage body position suitable for patient, so that several peltier that enter working state due to power on can form temperature sensing area in the form of the upper surface of upper limb part contacted with patient to indicate patient to adjust to correct body position.

[0009] Medical staff can accurately detect the accumulation position of sputum in patient's lung using ultrasonic equipment, thereby determining the best body position drainage scheme for the patient individually. Subsequently, the peltier at a specific position inside the upper limb part is driven by the controller to work, so as to construct an intuitive temperature sensing area on its surface, providing immediate feedback for the patient to adjust the body position, significantly improving the accuracy and efficiency of body position drainage. By accurately controlling the operation of peltier, not only can the patient be effectively stabilized in the best treatment position, but also the risk of treatment effect attenuation caused by improper body position can be significantly reduced. In addition, the peltier element has the characteristics of instant response, which can quickly start and work when powered on, and immediately stop running when powered off. This working mode significantly speeds up the formation and regression process of the temperature sensing area. Since the peltier can quickly adjust the temperature, it can be easily switched between different drainage body positions to meet the treatment needs of the patient. This rapid temperature change capability enables the patient to quickly adjust to the best body position, thereby improving the efficiency and treatment effect of body position drainage.

[0010] According to a preferred embodiment, the upper limb part comprises a main block, wherein two sides of the main block are provided with barriers, which define the boundary of the patient's upper body movement range in the form of being higher than the upper surface of the main block. The barriers on both sides of the main block are higher than the upper surface, forming a physical boundary to limit the movement of the patient's upper body. This design helps to stabilize the position of the patient's upper body, reduce unnecessary movement during treatment, and prevent accidental slipping or moving to an inappropriate position during treatment.

[0011] According to a preferred embodiment, the main block is configured with a skeleton inside for holding and supporting the upper surface and the lower surface thereof, and the wires connected with the several Peltier devices can be fixed on the skeleton. The skeleton configured inside the main block can provide additional support and strength, ensuring that the main block remains stable when carrying the patient's upper body. This structural design helps to distribute the weight of the patient, reducing discomfort or injury caused by pressure concentration. Fixing the wires connected with the Peltier devices on the skeleton helps to maintain the orderly arrangement of the wires, avoiding disorganized or entangled wires, thereby improving the reliability and safety of the device.

[0012] According to a preferred embodiment, the main block is configured with several protrusions protruding from its upper surface, and part of the protrusions can form several working groups on the upper surface of the main block in a form corresponding to the shape and position of several standard drainage body positions, wherein the lower part of the protrusions in the same working group are configured with Peltier devices electrically connected with the controller through the same wire, and the cooling surfaces of these Peltier devices face the internal cavities of the protrusions. The human body is more sensitive to temperature changes below body temperature, and using the cooling surface of the Peltier device can more accurately control the temperature of the protrusions in contact with the human body, keeping it within the appropriate low temperature range, thereby improving the user's perception sensitivity. The lower part of the protrusions in the same working group is configured with Peltier devices electrically connected with the controller through the same wire, which means that medical staff can manually control the cooling of each working group individually. This modular cooling design improves the flexibility and efficiency of the system. Medical staff can operate the controller to disconnect the power supply after the patient is adjusted to the correct drainage body position, so as to avoid the continuous stimulation of the low temperature of the Peltier device to the patient's skin. In addition, medical staff can also start and stop the corresponding Peltier devices intermittently according to the treatment time of the patient, so as to relieve the pressure sores that may be caused by the patient maintaining the same drainage posture for a long time through the cooling effect of the Peltier device.

[0013] According to a preferred embodiment, the main block is internally integrated with a plurality of temperature sensors in a manner corresponding to the location of the temperature-sensitive area, the temperature sensors are arranged in the internal cavities of the protrusions within the temperature-sensitive area to capture the temperature changes of the respective areas, and each temperature sensor is electrically connected to the controller. By arranging the temperature sensors in the cavities inside the protrusions, the temperature changes of the areas corresponding to the temperature-sensitive area can be directly monitored. This layout enables the temperature sensors to more accurately capture local temperature changes, thereby improving the accuracy of temperature monitoring. Each temperature sensor is electrically connected to the controller, which means that temperature data can be transmitted to the controller in real time.

[0014] According to a preferred embodiment, the internal cavity wall of the protrusion is surrounded by a filling layer composed of thermal insulation material, wherein the filling layer retains an opening at the top area of the internal cavity wall directly contacting the patient's skin. The filling layer composed of thermal insulation material can effectively prevent heat exchange between the inside of the protrusion and the external environment. This local thermal insulation helps to maintain the temperature inside the protrusion and reduces energy loss, improving energy efficiency. Due to the thermal insulation effect of the filling layer, the temperature changes inside the protrusion will not be affected by the temperature fluctuations of the external environment, so that the temperature of the area directly contacting the patient's skin can be more accurately controlled. The opening retained at the top area of the internal cavity wall directly contacting the patient's skin allows the temperature of this area to be directly in contact with the patient's skin, which can provide a more direct temperature sensation for the patient.

[0015] According to a preferred embodiment, the upper limb part includes an additional block detachably connected to the main block, and the additional block is assembled on both sides of the main block in a manner matching the insertion interfaces reserved on the containment side. By disassembling the upper limb part into a detachable main block and an additional block, a modular design is achieved. This design allows flexible adjustment or replacement of the components of the upper limb part to correspond to the drainage position adopted by the patient according to different patient treatment needs. In addition, the insertion interface design of the containment side allows medical staff to quickly and stably assemble the appropriate additional block according to the treatment needs.

[0016] According to a preferred embodiment, the upper limb part is provided with a headrest, which is arranged at the end away from the lower limb part and above the upper surface of the main block, and the end close to the protrusion is provided with a slope matching the curvature of the neck. The design of the headrest helps to support the patient's neck and maintain the natural curvature of the cervical spine, avoiding excessive tension or discomfort of the neck muscles and cervical spine during long-term treatment. In addition, a suitable headrest design can encourage the patient to maintain the recommended body position, as an improper head position can cause discomfort, thereby prompting the patient to naturally adjust to a more comfortable and correct body position.

[0017] According to a preferred embodiment, the lower limb part is detachably connected with the upper limb part, wherein at least a part of the area of the lower limb part contacting the upper surface of the patient's body is recessed downward to form a second positioning groove for guiding the placement posture of the patient's lower limbs, and the second positioning grooves equipped on different lower limb parts correspond to different standard drainage body positions in different shapes. The second positioning groove of the lower limb part is designed to guide the placement posture of the patient's lower limbs, and the shape and size thereof can be adjusted according to different standard drainage body positions to adapt to the anatomical structure and treatment needs of different patients. The recessed design of the second positioning groove can better fit the curve of the patient's lower limbs, provide stable support, and reduce the discomfort of the patient caused by maintaining the same posture for a long time. Through accurate guidance of the placement posture of the lower limbs, the second positioning groove helps the patient to maintain the correct body position, thereby improving the treatment effect of body position drainage and promoting the discharge of sputum.

[0018] According to a preferred embodiment, the additional block is recessed downward at least in a part of the area of the additional block contacting the upper surface of the patient's body to form a first positioning groove for guiding the placement posture of the patient's upper limbs, and the first positioning grooves equipped on different additional blocks correspond to different standard drainage body positions in different shapes. By designing the first positioning grooves in different shapes, the additional block can provide a clear placement position for the patient's upper limbs, ensuring that the patient can correctly place the upper limbs according to the requirements of the standard drainage body position. Different additional blocks are equipped with first positioning grooves of different shapes, so that the auxiliary device can adapt to multiple standard drainage body positions, increasing the application range and flexibility of the device, and medical staff can quickly identify and use additional blocks matched with specific drainage body positions, simplifying the treatment preparation process and improving the work efficiency of medical staff. The recessed design of the first positioning groove can better fit the curve of the patient's upper limbs, provide stable support, and reduce the discomfort of the patient caused by maintaining the same posture for a long time.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] This utility model relates to a postural drainage assist device for lung ultrasound, which is designed to improve the accuracy and comfort of patients during postural drainage. Figure 1 As shown, the device comprises an upper limb section 100, a lower limb section 200, and an ultrasound device 300. Inside the upper limb section 100, a series of Pellets 114 are arranged according to the specific shape and spatial position of standard clinical drainage positions (such as lateral decubitus and supine positions). These Pellets 114 are flat and positioned close to the inner surface of the upper limb section 100 to ensure that temperature changes are transmitted instantly. Each Pellet 114 corresponding to a standard drainage position can be connected in parallel or series to a dedicated lead wire. These lead wires extend from inside the upper limb section 100 and form an electrical connection with an external controller 116.

[0031] Preferably, the medical staff can use the ultrasound device 300 to scan the patient's lungs to accurately identify the sputum accumulation area, and determine the optimal body position drainage posture accordingly. Specifically, the ultrasound device 300 includes an ultrasound probe 310 and an ultrasound imager 320. When the medical staff operates the ultrasound device 300, the ultrasound probe 310 is used to scan the patient's chest, and the ultrasound imager 320 is used to observe and identify abnormal areas in the lung image, such as high-density shadows or echo-enhanced areas, which usually indicate sputum accumulation. With professional knowledge and experience, the medical staff can determine the specific location of sputum accumulation in the lungs, providing accurate basis for subsequent body position drainage treatment. Subsequently, the medical staff can activate a number of Peltier devices 114 corresponding to the body position by using the controller 116. When the Peltier devices 114 are activated due to power-on, they will form a clear temperature-sensitive area on the upper surface of the upper limb part 100 in contact with the patient, which provides intuitive tactile feedback through temperature changes (preferably in the form of cooling), effectively guiding the patient to adjust to the correct body position. This design not only ensures the accurate implementation of body position drainage, but also greatly improves the patient's participation and compliance, making the entire treatment process smoother and more efficient.

[0032] Preferably, as shown in Figure 2 The design of the upper limb part 100 adopts a modular concept, including a main block 110 and an additional block 120, to facilitate adjustment and assembly according to the specific needs of the patient. The main block 110 serves as the basic support structure, and the two vertical edges of the main block 110 are equipped with barriers 111. These barriers 111 are perpendicular to the upper surface of the main block 110 and have a certain height, to ensure the stability and safety of the patient's upper body during treatment. There is enough distance between the two barriers 111 to fully accommodate the various body positions that the patient may adopt while lying on the main block 110. The height of the barriers 111 is designed in consideration of ergonomics, which can limit the movement of the patient's upper body and prevent them from falling off the surface of the main block 110 during treatment, without unnecessarily restricting the patient's limb movement. The design of the additional block 120 provides additional support and customization for the main block 110. They are matched with the reserved interfaces on the sides of the barriers 111 of the main block 110 through precisely designed plug-in interfaces, ensuring that the additional block 120 can be stably installed on both sides of the main block 110. This plug-in interface design facilitates the installation and removal of the additional block 120, and the installation position of the additional block 120 can be individually configured according to the patient's anatomical structure and the requirements of the treatment body position.

[0033] Preferably, as shown in Figure 2 , Figure 3 , Figure 5As shown, the upper surface of the main body block 110 has multiple local protrusions, referred to as bumps 112, designed to provide specific temperature sensing upon contact with the patient's body. By design, each bump 112 has an internal cavity structure capable of accommodating a Peltier element 114. The Peltier 114 is positioned within the main body block 110, corresponding to the specific location of the bumps 112, ensuring that its cooling surface effectively contacts the internal cavity of the bump 112, thereby improving cooling efficiency. Through this design, the air within the internal cavity of the bump 112 can be sufficiently cooled by the Peltier 114, creating a significant temperature gradient that exhibits a marked temperature difference compared to surrounding inactive bumps 112 and bumps without Peltier 114. During operation, the controller 116 is responsible for activating the corresponding Peltier 114. Once activated, the temperature within the relevant bump 112 drops significantly, creating a temperature difference that results in these specific bumps 112 having a lower temperature than the surrounding inactive areas. This temperature difference allows patients to directly perceive different temperature zones through their skin, thus forming a temperature-sensing zone, such as... Figure 6 to Figure 8 As shown in the image. This feedback mechanism provides patients with intuitive information indicating whether their posture is within the correct range, ensuring effective monitoring and adjustment.

[0034] Preferably, to ensure that the patient's skin can sensitively perceive temperature fluctuations at the protrusion 112, the inner cavity wall of the protrusion 112 is designed with a filling layer made of heat-insulating material. This filling layer is designed to effectively isolate and limit the diffusion of the low temperature generated by the Peltier 114 to the surrounding area of ​​the protrusion 112, ensuring that the upper surface of the main body block 110 only shows significant temperature changes at the protrusion 112 location, thereby optimizing the effect of guiding the patient to adjust to the correct body position. It is worth noting that the filling layer inside the protrusion 112 does not completely cover the entire area of ​​the cavity wall, but deliberately retains an opening design at the top of the cavity wall, that is, the area in direct contact with the patient's skin. This design aims to avoid the filling layer interfering with the temperature transmission to the patient's skin, ensuring that the patient can perceive the temperature changes of the protrusion 112 without obstruction. The design of the temperature-sensing zone is intended to assist the patient in adjusting their body position according to temperature changes to ensure the effectiveness of postural drainage therapy. In this way, the protrusion 112 not only serves as a body position support point, but also has the function of guiding the patient to the correct body position, making the treatment process more intuitive and effective.

[0035] Preferably, such as Figure 6 to Figure 8As shown, some of the protrusions 112 are divided into three groups according to the location of the temperature-sensing zone they form: the first working group 112a corresponding to the right lateral decubitus position, the second working group 112b corresponding to the left lateral decubitus position, and the third working group 112c corresponding to the supine position. Each group of protrusions 112 has a corresponding Peltier element 114 positioned below it, ensuring efficient heat conduction. During operation, the controller 116 has three sets of switches to activate the Peltiers 114 in each group. When the controller 116 provides current to the Peltier 114 of a particular working group, the temperature within the corresponding protrusion 112 will significantly decrease, resulting in a lower temperature state than the other two groups of protrusions 112 and the protrusions 112 not assigned to a working group. This design allows the patient to perceive temperature changes in specific areas under different body positions, providing effective postural feedback and helping them maintain the correct posture.

[0036] like Figure 6 As shown, when a patient needs to undergo lung drainage treatment in a right lateral decubitus position, the Pellets 114 corresponding to the first working group 112a will be activated. Medical staff can selectively connect the wires connected to several Pellets 114 corresponding to the right lateral decubitus position through the operating controller 116, so that these Pellets 114 enter the working state, thereby forming a temperature-reduced temperature-sensing zone on the surface of the protrusions 112 in contact with the patient on the upper limb 100 to instruct the patient to adjust their body to the position indicated by the first working group 112a.

[0037] like Figure 7 As shown, when a patient needs to undergo lung drainage treatment in a left lateral decubitus position, the Pellets 114 corresponding to the second working group 112b will be activated. Medical staff can selectively connect the wires connected to several Pellets 114 corresponding to the left lateral decubitus position through the operating controller 116, so that these Pellets 114 can enter the working state, thereby forming a temperature-reduced temperature-sensing zone on the surface of the protrusions 112 in contact with the patient on the upper limb 100 to instruct the patient to adjust their body to the position indicated by the second working group 112b.

[0038] like Figure 8 As shown, when a patient needs to undergo lung drainage treatment in a supine position, the Pelta 114 corresponding to the third working group 112c will be activated. Medical staff can selectively connect the wires connected to several Pelta 114s corresponding to the supine position through the operating controller 116, so that these Pelta 114s can enter the working state, thereby forming a temperature-reduced temperature-sensing zone on the surface of the protrusion 112 in contact with the patient on the upper limb 100 to instruct the patient to adjust their body to the position indicated by the third working group 112c.

[0039] Preferably, the arrangement of the protrusions 112 should follow these principles: they should not be too close together to avoid causing discomfort to the patient's skin, nor should they be too wide to ensure effective guidance for the patient's postural adjustment. For applications involving adult patients, the ideal spacing between the protrusions 112 is set to 5 to 10 centimeters, a configuration designed to achieve optimal comfort and guidance.

[0040] Preferably, such as Figure 2 , Figure 3 As shown, the attachment block 120 is designed to include a surface that contacts the patient's upper limb, and at least a portion of it is intentionally recessed to form a first positioning groove 121 for guiding the correct placement of the patient's upper limb. The geometry and dimensions of the first positioning groove 121 are designed to mimic the natural hanging posture of the patient's arm, adapting to the requirements of different standard drainage positions, thereby avoiding the impact of improper arm posture on the drainage effect. The groove is arc-shaped, effectively accommodating the natural curve of the arm and providing stable support, especially when the forearm and upper arm are naturally bent, the first positioning groove 121 can match well with them. For adult patients, the length of the first positioning groove 121 is set to approximately 25-30 cm to accommodate the length of most adult upper limbs. To meet the needs of patients of different body types, the width of the first positioning groove 121 is designed to be 6-10 cm and the depth is designed to be 3-5 cm, ensuring that both thin and relatively robust patients can comfortably place their arms. In addition, the first positioning groove 121 also has a certain inclination, so that the forearm is naturally raised when the patient's arm is placed, simulating a relaxed daily posture. In this way, the first positioning groove 121 ensures that the patient's upper limbs can be stably placed in the predetermined position during postural drainage, thereby improving the treatment effect.

[0041] Preferably, such as Figure 3 As shown, the add-on block 120 can be equipped with various shapes of first positioning slots 121 to achieve individualized treatment, depending on different drainage position requirements. The shape design of these positioning slots references the natural positioning posture of the human upper limb in different drainage positions, ensuring that the patient receives appropriate support and positioning in various drainage positions. In addition, the design of the positioning slots also takes into account the patient's comfort to reduce discomfort that may occur during prolonged treatment. Through this structural design, the add-on block 120 can provide customized positional support for patients and optimize the therapeutic effect of positional drainage.

[0042] Preferably, such as Figure 2As shown, the upper limb portion 100 also includes a headrest 115 assembly designed to support the patient's head. The headrest 115 is constructed such that its top edge is higher than the upper surface of the main body block 110 to conform to the natural shape of the human head. The headrest 115 is positioned on the side of the upper limb portion 100 closest to the patient's head to provide a stable head support point. The side of the headrest 115 near the protrusion 112 on the upper surface of the main body block 110 is specifically designed with a slope that conforms to the physiological curve of the neck. This design ensures that the headrest 115 not only supports the patient's head but also conforms to the contour of the patient's neck, maintaining the natural curvature of the cervical spine. This allows the patient to maintain head and neck comfort during postural drainage therapy, reducing neck muscle tension and pressure, thereby improving overall treatment effectiveness and patient comfort.

[0043] Preferably, such as Figure 2 to Figure 4 As shown, the lower limb portion 200 is designed for quick-detachment connection with the upper limb portion 100, facilitating adjustment or replacement as needed for treatment. At least a portion of the surface of the lower limb portion 200 that contacts the patient's lower limb is designed with a recessed structure, forming second positioning grooves 210. The geometry and dimensions of these second positioning grooves 210 are designed to guide the patient's lower limb into a specific positioning posture corresponding to that in the upper limb portion 100, thereby accommodating different standard drainage positions. To meet the needs of different patients and different drainage positions, the lower limb portion 200 can be equipped with various second positioning grooves 210 of different shapes.

[0044] In summary, both the lower limb unit 200 and the additional block 120 are key components of the lung ultrasound-guided positioning and drainage assistive device. Both can be quickly and securely assembled onto the main body block 110 based on the drainage position determined by medical personnel using the ultrasound equipment 300. The second positioning groove 210 of the lower limb unit 200 is specifically designed to guide the patient's lower limbs to a suitable positioning posture, while the additional block 120 precisely matches the pre-reserved insertion interface on the side of the main body block 110's enclosure 111, ensuring proper support and positioning of the patient's upper limbs. At least a portion of the upper surface of the additional block 120 is designed with first positioning grooves 121. These recessed structures exhibit various shapes depending on the standard drainage position to accommodate the correct placement of the patient's upper limbs. The integrated function of these structures not only ensures that the patient maintains the correct position during positioning and drainage treatment but also provides the necessary comfort and stability, together constituting a comprehensive assistive device designed to improve treatment effectiveness and optimize the patient's treatment experience.

[0045] Preferably, the upper limb 100 integrates multiple temperature sensors, which are positioned corresponding to the temperature sensing zones to capture temperature changes in their respective areas. More preferably, each temperature sensing zone contains at least one temperature sensor, and each sensor is placed within the internal cavity of one of the protrusions 112 within its respective zone and electrically connected to the controller 116. This allows medical personnel to adjust the controller 116 based on the current temperature of the sensing zone to maintain the set temperature of the Peltier 114 within the preset temperature range of the sensing zone, ensuring the accuracy and comfort of the patient's postural drainage treatment. In this way, the temperature sensor not only serves as a temperature monitoring unit but also as a key component for achieving precise temperature control. Preferably, the temperature sensor can be a sensor from series such as OMRON E52, NST, or MLX, which includes small sensors with a diameter of φ8mm, suitable for placement within the internal cavity of the protrusion 112.
