Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a side-lying infusion-type double-layer arm-fixing surgical pillow. Background Art

[0002] During the operation, the patient's position is crucial for the smooth progress of the operation, the convenience of operation of medical staff and the comfort of the patient. The correct position can ensure the full exposure of the surgical field, facilitate the doctor's operation, and reduce the occurrence of surgical complications. The lateral position is one of the common positions in surgery, especially for surgery on the chest, lateral waist, hip joint and other parts. At this time, it is particularly important to fix the patient's head, arms and lower limbs to ensure the stability of the operation and the safety of the patient. After the operation is completed, especially after the side-lying type of surgery, the patient is often required to remain in a side-lying state for recovery to prevent pulling on the postoperative wound. In addition, in the actual patient treatment process, patients with some diseases must also remain in a side-lying state. For example, for bedridden patients with endotracheal intubation, during the process of drainage and sputum removal, the patient needs to remain in a side-lying position. It is easy for patients to remain in a side-lying position in a state of awake consciousness, but it is difficult for patients to remain in a side-lying resting position under sedation or other unconscious states.

[0003] In addition, during and after surgery, patients need infusions and other medical procedures on their wrists or arms. During anesthesia recovery, people's bodies and arms tend to turn over unconsciously. At this time, the turning of the body or the movement of the arms may affect the surgical area or involve the surgical drainage tube, leading to certain medical risks.

[0004] In response to the above problems, the traditional operation method is to fix the arm with materials such as bandages, wraps or arm supports, but this fixation method is very inconvenient and usually requires the assistance of other personnel; in addition, these fixation methods usually only bind and fix the arm alone, which is not convenient for the patient to place the arm when lying on the side. At the same time, this fixation method cannot be untied by the patient after surgery, and requires the assistance of other personnel. In addition, the traditional fixation has obvious shortcomings in terms of fixation effect and comfort, such as easy loosening, inconvenience in injection and infusion, and too low elbow position. The fixed structure composed of bandages, wraps or arm supports requires medical staff to manually fix it many times, which is inefficient. In addition, the traditional postoperative arm fixation is simply stacked, which will also affect the effect of infusion and other medical operations. Summary of the invention

[0005] (I) Technical problems solved: In view of the deficiencies of the prior art, the present invention provides a side-lying infusion type double-layer arm-fixing surgical pillow, which uses the pressure of the patient's head on the pillow to limit the arm, and does not require medical staff to use bandages, wraps or hand supports to fix the patient's arms many times. The pillow can be reused many times, and the present invention divides the hand pillow into two upper and lower grids, so that both upper limbs can be placed in one grid respectively, keeping the hands stable, so that the elbows have a certain height, and also conducive to the stability of the side-lying position. At the same time, both upper limbs are placed parallel to the side of the face, which is the same as the natural placement of the hands during normal sleep. Compared with using bandages, wraps or hand supports, it is more in line with the natural position of both upper limbs when the human body is sleeping on the side. Both upper limbs are placed flat in one grid respectively, which is convenient for medical staff to give injections and infusions during surgery, and avoids the infusion line from being bent and affecting the efficiency and effect of infusion.

[0006] (II) Technical solution: To achieve the above-mentioned purpose, the present invention provides the following technical solution: a side-lying infusion-type double-layer arm-fixing surgical pillow, comprising a pillow and a fixing frame part, the fixing frame is designed with a placement groove of a double-layer upper and lower structure, the placement grooves at the upper and lower positions of the fixing frame are respectively designed with lateral openings for convenient arm placement, the upper and lower ends of the opening position of each layer of the placement groove of the fixing frame are respectively designed with fixed air bags, the fixed air bags are in a contracted state when not inflated, the pillow is designed with an air delivery air bag made of elastic material, and the air delivery air bag is connected to the fixed air bag through a trachea.

[0007] When in use, the patient's head is separated from the upper surface of the pillow, the air delivery airbag is in an expanded state, and the fixed airbag is in a contracted state. At this time, the patient's arms are first placed in the placement grooves of the upper and lower layers of the fixing frame respectively, and then the patient's head is pressed on the pillow. The gravity of the head squeezes the air delivery airbag, and the gas in the air delivery airbag is pressed into the fixed airbag. After the fixed airbags in the upper and lower layers of the fixing frame are inflated, the patient's arms are locked in the placement grooves of the fixing frame.

[0008] Preferably, the fixing frame adopts an integrated structure, a bottom plate is designed at the bottom of the fixing frame, and a horizontal middle plate and upper plate are designed above the plane of the bottom plate; one side of the middle plate and the upper plate are connected to the bottom plate through a side plate, and the other sides of the bottom plate, the middle plate and the upper plate are open to form the placement grooves placed up and down; one end of the bottom plate is extended, and the pillow is placed on the upper surface of the extended end, and the fixed airbags are respectively assembled at the upper and lower positions of the corresponding lateral openings of the bottom plate, the middle plate and the upper plate.

[0009] Preferably, the upper and lower surfaces of the placement groove are designed with hand rests, and the bottom plate, middle plate and upper plate are integrated by plastic injection molding.

[0010] Preferably, cotton is filled between the pillow and the air delivery airbag, and both the air delivery airbag and the fixed airbag are made of rubber.

[0011] Preferably, a gas inlet for installing a trachea is provided on the side surface of the pillow, and the gas inlet and the trachea are detachably connected.

[0012] Preferably, the pillow is designed with a raised silicone pad at one end near the patient's armpit, and when the patient lies on his side, the silicone pad fits in the patient's armpit.

[0013] Preferably, the fixing frame is designed with an adjustment frame at the connection of the double-layer structure, and the adjustment frame includes an upper adjustment plate and a lower adjustment plate, and the upper adjustment plate and the lower adjustment plate are fixedly connected to the lower surface of the upper layer and the upper surface of the lower layer of the fixing frame respectively.

[0014] Preferably, a base is designed at the bottom of the fixing frame, and the fixing frame is placed on the ground near the side of the bed where the patient is located through the base.

[0015] Preferably, a main shaft is designed between the upper adjustment plate and the lower adjustment plate, and threaded holes are provided in the upper and lower adjustment plates near the main shaft ends. The main shaft is cylindrical, and threaded holes arranged in a circular array are designed on the surface of the main shaft. The upper and lower adjustment plates are detachably connected to the main shaft through threaded holes and bolts.

[0016] Preferably, the fixing frame is divided into two layers, an upper layer and an lower layer, a placement groove is designed on the upper surface of the double-layer structure, an armrest is installed at the bottom of the placement groove, and fixed airbags are designed and installed on both sides of the upper end of the placement groove. Beneficial Effects

[0017] 1. The side-lying infusion double-layer arm fixed surgical pillow can be used in side-lying surgery, in the postoperative recovery process of side-lying surgery, and when the side-lying position is required in the ICU or ward. The device is equipped with an air-transmitting airbag inside the pillow, which is connected to the fixed airbag through a trachea. When using the fixed frame during surgery, after the patient loses his or her consciousness and is placed in a side-lying position, the medical staff will first place the patient's arm into the placement slot. At this time, the fixed airbag is not inflated. After the arm is adjusted, the medical staff will lift the patient's head and place the pillow under the head. The weight of the head is used to press the airbag in the pillow downward. After the airbag is compressed, the air in the airbag moves through the trachea to the inside of the fixed airbag, so that the fixed airbag is inflated. When the fixed airbag is inflated, the protruding structure will automatically lock the arm to complete the limit. This locking method is achieved through an airbag structure, which is not only gentler, but also the locking of the wrist or arm position is synchronized with the action of the patient's head pressing on the pillow. In this way, when the patient feels uncomfortable with the locked part, the patient's head and the locked arm or wrist will shake unconsciously, which can loosen the lock and make the locked arm or wrist automatically move in a small range, thereby ensuring the blood flow of the locked part of the arm or wrist, and at the same time preventing the fixed arm or elbow from completely detaching when the patient is unconscious.

[0018] 2. When anesthesia recovery patients, ICU sedation awake patients or ward awake patients need to maintain a lateral position, the patients can use it by themselves, and the hand can be locked by pressing the pillow with the head. When the arm or wrist needs to be removed, the patient can release the fixed airbag that locks the arm or wrist by raising his head, so that the patient can take out his hand by himself. This design is more convenient than the traditional arm fixation method using bandages, wraps or hand supports. As long as the patient's head presses on the pillow, the position can be limited. When the patient's head leaves the pillow, the fixed airbag that locks the arm can be released. No outside assistance is required, which can greatly reduce the workload of bedside personnel. At the same time, the patient can easily adjust to a comfortable position by raising his head.

[0019] 3. Since the arms are restrained by airbags made of rubber, the arms have a certain degree of freedom of movement inside the fixed airbags, avoiding muscle tension and blood circulation problems caused by the arms being in a rigid state for a long time. At the same time, the upper limbs are placed parallel to the sides of the face, which is the same as the natural placement of the hands when sleeping on the side. Compared with bandages, wraps or hand supports, it is more in line with the natural relaxation of the upper limbs when sleeping on the side. The upper limbs can be placed in a grid separately, which is convenient for medical staff to give injections and infusions during or after surgery, and avoid the infusion line being folded to affect the efficiency and effect of the infusion.

[0020] 4. The side-lying infusion double-layer arm-fixing surgical pillow is designed with a silicone pad that fits the armpit on the side close to the patient's armpit. When the patient needs to undergo side-lying surgery and lies on his side on the bed, the silicone pad is just located under the patient's armpit, supporting the armpit space after the patient raises his arm, preventing the patient from maintaining a side-lying position for a long time, resulting in prolonged compression of one side of the limbs or joints, and reducing the discomfort such as soreness or numbness experienced by patients after surgery.

[0021] 5. The side-lying infusion double-layer arm-fixed surgical pillow can adopt an independent structure. The fixing frame is separated from the bed where the patient is located, and the angle between the upper and lower layers of the fixing frame can be changed through the adjustment frame to adapt to patients of different body shapes and different surgical requirements. At the same time, the surgical pillow has a simple structure and is easy to implement. The fixing frame structure can be specifically set according to different side-lying needs. It is convenient to realize patient autonomous control by only ensuring that the air-transmitting airbag is connected to the fixed airbag. At the same time, the patient can autonomously control this surgical pillow through the movement of the head. In an unconscious state, the fixed airbag of the fixing frame part can also interact with the air-transmitting airbag of the patient's head pillow. When the patient is uncomfortable lying on his side for a long time, the arm fixing part can be adjusted through the patient's unconscious head movement to ensure that the blood vessels in the locking part of the arm or wrist are unobstructed.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0026] Example 1: Please refer to Figure 1-3 , A side-lying infusion type double-layer arm-fixing surgical pillow, a side-lying infusion type double-layer arm-fixing surgical pillow, comprising a pillow 1 and a fixing frame 2, the fixing frame 2 is designed with a placement groove 201 of a double-layer upper and lower structure, the placement grooves 201 at the upper and lower positions of the fixing frame 2 are respectively designed with lateral openings for convenient arm placement, the upper and lower ends of the opening position of each layer of the placement groove 201 of the fixing frame 2 are respectively designed with fixed airbags 202, the fixed airbags 202 are in a contracted state when not inflated, the pillow is designed with an air delivery airbag 101 made of elastic material, the air delivery airbag 101 is connected with the fixed airbag 202 through a trachea 3; See also Figure 3 When in use, the medical staff lifts the patient's head to separate it from the upper surface of the pillow 1, the air delivery bag 101 is in an expanded state, and the fixed bag 202 is in a contracted state. At this time, the medical staff places the patient's arms in the placement grooves 201 of the upper and lower layers of the fixing frame 2, and then presses the patient's head on the pillow 1; the pillow 1 can also be temporarily removed first, the fixed bag 202 is in a contracted state, and the medical staff places the patient's arms in the placement grooves 201 of the upper and lower layers of the fixing frame 2, and then lifts the patient's head and places the pillow 1 under the patient's head. The gravity of the head squeezes the air delivery bag 101, and the gas in the air delivery bag 101 is pressed into the fixed bag 202. After the fixed bags 202 of the upper and lower layers of the fixing frame 2 are inflated, the patient's arms are locked in the placement grooves 201 of the fixing frame 2.

[0027] See also Figure 2The fixing frame 2 adopts an integrated structure, and a bottom plate 203 is designed at the bottom of the fixing frame 2, and a horizontal middle plate 204 and an upper plate 205 are respectively designed above the plane of the bottom plate 203; one side of the middle plate 204 and the upper plate 205 are connected to the bottom plate 203 through a side plate 206, and the other sides of the bottom plate 203, the middle plate 204, and the upper plate 205 are open to form the placement slots 201 placed up and down; one end of the bottom plate 203 is extended, and the pillow 1 is placed on the upper surface of the extended end. This design uses the pressure generated by the patient's head to fix the device, and no additional fixing equipment is required; the fixed airbags 202 are respectively assembled at the upper and lower positions of the corresponding lateral openings of the bottom plate 203, the middle plate 204, and the upper plate 205.

[0028] See also Figure 2 The upper and lower surfaces of the placement groove 201 are designed with hand pillows 207, which are used to improve the comfort of arm placement and are made of soft material; the bottom plate 203, the middle plate 204, and the upper plate 205 are processed as a whole by plastic injection molding, which reduces the overall weight of the device and facilitates the placement of the device on the bed.

[0029] See also Figure 7 The pillow 1 and the air delivery bag 101 are filled with cotton. Both the air delivery bag 101 and the fixed air bag 202 are made of rubber. Rubber, as a highly elastic material, has the ability to return to its original state after being squeezed and deformed if the applied external force disappears. The specific manifestation of the application in the present invention is: when the patient's head leaves the pillow 1, the air delivery bag 101 inside the pillow 1 returns to its original state, so that the gas in the fixed air bag 202 returns to the inside of the air delivery bag 101 through the trachea 3.

[0030] See also Figure 1-2 The side surface of the pillow 1 is provided with an air delivery port 102 for installing the trachea 3 , and the air delivery port 102 and the trachea 3 are detachably connected.

[0031] See also Figure 1 , 2 7. The pillow 1 is designed with a raised silicone pad 103 at one end near the patient's armpit. When the patient lies on his side, the silicone pad 103 fits the patient's armpit. When the patient needs to undergo a side-lying surgery and lies on his side on the bed, the silicone pad 103 is just located at the patient's armpit, supporting the armpit space after the patient raises his arm, preventing the patient from maintaining a side-lying posture for a long time, which causes the limbs or joints on one side to be compressed for a long time, and reducing the discomfort such as soreness or numbness of the patient after the operation.

[0032] In actual use, when the patient needs to lie on the bed in the side-lying position, the medical staff first lifts the anesthetized patient's head to make it leave the pillow 1, and then puts the patient's arm into the placement slot 201. At this time, the fixed airbag 202 is not inflated, and the medical staff can freely adjust the patient's arm in the placement slot 201. After the adjustment is completed, the medical staff rests the patient's head on the pillow 1. The pillow 1 can also be temporarily removed first, and the patient's arm is placed in the placement slot 201 and adjusted to a suitable position. The medical staff lifts the patient's head and re-places the headrest 1 under the patient's head. The patient's head gravity is used to press the air delivery bag 101 in the pillow 1 downward. After the air delivery bag 101 is compressed, the air in the air delivery bag 101 moves to the inside of the fixed bag 202 through the trachea 3, so that the fixed bag 202 is inflated. When the fixed bag 202 is inflated, the protruding structure will lock the arm and complete the limit. This design is more convenient and stable than the traditional arm fixing method using bandages, wraps or hand supports. As long as the patient's head causes pressure on the pillow 1, the limit can be achieved. The patient can restore the freedom of the arm when leaving the pillow 1, and because the air bag made of rubber material is used to restrict the arm, the arm has a certain degree of freedom of movement inside the fixed bag 202, avoiding muscle tension and tissue necrosis caused by the arm being in a state of stalemate for a long time. This method is also in line with the natural posture when sleeping on the side. The two upper limbs are placed flat in a grid, which is convenient for medical staff to give injections and infusions during surgery, and avoids the infusion pipeline from being folded and affecting the efficiency and effect of infusion.

[0033] Example 2: Please refer to Figure 4-6 In another embodiment of the present invention, the fixing frame is designed with an adjustment frame 4 at the connection of the double-layer structure, which is used to adjust the distance between the double-layer structures to adapt to the body shapes of different patients. The adjustment frame 4 includes an upper connecting plate 401 and a lower connecting plate 402, and the upper connecting plate 401 and the lower connecting plate 402 are fixedly connected to the lower surface of the upper layer of the fixing frame and the upper surface of the lower layer respectively.

[0034] See also Figure 4 The bottom of the fixing frame is designed with a base 208 to enhance stability and prevent the fixing frame from sliding during surgery. The fixing frame is placed on the ground near the side of the patient's bed through the base 208.

[0035] See also Figure 5A main shaft 403 is designed between the upper connecting plate 401 and the lower connecting plate 402. The upper connecting plate 401 and the lower connecting plate 402 are provided with threaded holes at one end close to the main shaft 403. The main shaft 403 is cylindrical, and the surface of the main shaft 403 is provided with threaded holes arranged in a circular array. The upper connecting plate 401 and the lower connecting plate 402 are detachably connected to the main shaft 403 through the threaded holes and bolts. The user can change the position between the upper and lower layers of the fixing frame 2a by disassembling and changing the angle formed by the upper connecting plate 401 and the lower connecting plate 402 on the main shaft 403.

[0036] See also Figure 6 The fixing frame 2a is divided into two layers, an upper layer and an lower layer, and a placement groove 201a is designed on the upper surface of the double-layer structure. An armrest 207a is installed at the bottom of the placement groove 201a, and inward fixed air bags 202a are designed and installed on both sides of the upper end of the placement groove 201a.

[0037] In actual use, another embodiment adopts an independent structure, the fixing frame 2a is separated from the bed where the patient is located, and the angle between the upper and lower layers of the fixing frame 2a can be changed by adjusting the frame 4 to adapt to patients of different body shapes and different surgical requirements.
