Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to a postoperative clinical pressure-resistant protective nursing device. Background Technology

[0002] After abdominal surgery, the incision is covered with gauze dressing, and various drainage tubes and catheters are inserted into the abdomen. Post-operatively, for warmth and concealment, blankets are often placed directly on the patient. This can easily lead to the following drawbacks: First, the blankets directly contact the wound and drainage tubes, causing pain and discomfort; second, it easily leads to contamination of the blankets and wound infection, especially in hot summer weather; third, the direct pressure on the drainage tubes may obstruct drainage, affecting the surgical and treatment outcomes. Furthermore, since the abdominal incision is below the chest, the pressure from blankets and during sleep can easily cause the wound to reopen. Currently, basic protection is only achieved by covering the wound with gauze, which still poses significant safety risks.

[0003] Currently, a shield is usually placed over the wound to cover it and isolate it from pressure. To ensure the shield's stability, it is usually tied or clamped to the patient. This requires careful control of the force applied to avoid patient discomfort while ensuring the shield's stability. However, the fixation force can only be judged based on the patient's own feelings or experience, making it difficult to control accurately. Excessive force can easily cause patient discomfort. In addition, due to the shield's obstruction, it is difficult to control the distance between the shield and the wound.

[0004] Therefore, a postoperative clinical pressure-resistant protective nursing device is needed to solve the above problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a postoperative clinical pressure-resistant protective nursing device, comprising: a clamping assembly for clamping on both sides of the patient's waist; a baffle disposed on the clamping assembly for shielding the surgical site on the patient's abdomen; the clamping assembly includes a base plate and two mounting platforms disposed opposite each other on the base plate, each mounting platform being provided with a sponge clamping plate, the two sponge clamping plates being disposed opposite each other; a driving assembly for driving the sponge clamping plates to clamp the patient's waist is disposed on the right mounting platform, the driving assembly including: an airbag cavity formed within the right mounting platform; a compression airbag disposed within the airbag cavity; and a compression plate slidably disposed within the airbag. Inside the cavity, pressure is applied to the compression bladder; a screw is rotatably mounted inside the bladder cavity and threadedly connected to the compression plate; a first handle is rotatably mounted on the mounting platform, and the first handle has a shaft portion that inserts into the mounting platform; an abutment wheel is slidably mounted on the shaft portion and rotates synchronously with the shaft portion; a transmission wheel is fixed to one end of the screw and is used to transmit the torque of the abutment wheel to the screw; a sliding sleeve slides along the axis of the shaft portion inside the mounting platform, and an abutment spring is provided between the sliding sleeve and the abutment wheel, with both ends of the abutment spring abutting against the abutment wheel and the sliding sleeve respectively; wherein, the abutment wheel is provided with axially protruding transmission teeth in the circumferential direction, and the transmission wheel has tooth grooves for the transmission teeth to be embedded, and the transmission teeth and tooth grooves have inclined surfaces that abut against each other.

[0007] The device is installed on the patient's waist by means of a sponge clamping plate and a drive assembly. At the same time, the device is equipped with abutment wheels and drive wheels. When the clamping force is too great, the abutment wheels and drive wheels will disengage under the action of the inclined surface, so as not to continue to increase the clamping force and avoid causing discomfort to the patient.

[0008] Furthermore, a rotating ring is rotatably connected inside the mounting platform on the right side, and a pushing part is provided on the sliding sleeve. The pushing part has a contact surface that slopes from near the abutting wheel to away from the abutting wheel. A pushing column that abuts against the contact surface is fixedly connected to the rotating ring. A positioning screw with one end protruding from the mounting platform is threaded onto the rotating ring. An arc-shaped groove for the positioning screw to pass through is also provided on the mounting platform.

[0009] With the addition of a rotating ring and a sliding sleeve, the compression of the abutment spring can be adjusted by rotating the ring when the clamping force needs to be adjusted. When the compression of the abutment spring is greater, the clamping force on the patient is also greater, making it easier for medical staff to control the clamping force on different patients.

[0010] Furthermore, the mounting platform has multiple sets of paired mounting cavities, with the two pairs of mounting cavities distributed vertically. A sliding rod with one end extending out of the mounting platform is slidably connected inside the mounting cavity, and the two vertically distributed sliding rods are connected to a sponge clamping plate through a universal ball joint.

[0011] Furthermore, an extension airbag is also provided inside the installation cavity. One end of the extension airbag is connected to one end of the slide rod, and the extension airbag and the compression airbag are connected through a first telescopic tube.

[0012] The extension airbag drives the slide bar to extend. Since the extension airbags are all connected to the compression airbags, the force of the extension airbags pushing the slide bar is consistent, ensuring that the clamping force applied to different areas of the patient is consistent.

[0013] Furthermore, the baffle includes a first plate and a second plate. The first plate is slidably disposed on the mounting platform on the left side. The second plate has a connecting strip that is inserted into the first plate and slidably connected to the first plate. A limit screw is threadedly connected to the first plate, and one end of the limit screw abuts against the connecting strip to limit the connection strip.

[0014] By setting the first plate and the second plate, the distance between the first plate and the second plate can be adjusted to adjust the blocking range. At the same time, by using the connecting strip and the limiting screw, the limiting screw is tightened so that one end of the limiting screw abuts against the connecting strip, thereby limiting the first plate and the second plate.

[0015] Furthermore, the first plate includes a sliding part slidably disposed on the mounting platform on the left side and a plate-shaped part hinged to the sliding part. A vertically extending sliding groove is provided on the mounting platform on the left side. The sliding part has a portion slidably disposed in the sliding groove. A vertically arranged threaded shaft is rotatably connected in the sliding groove. The threaded shaft passes through the portion of the sliding part located in the sliding groove and is threadedly connected to the sliding part. Coaxially arranged limiting sleeves are fixedly provided on both the sliding part and the plate-shaped part. Bolts pass through the two limiting sleeves to limit the sliding part and the plate-shaped part.

[0016] With its sliding and plate-shaped parts, when nursing operations are required, the plate-shaped parts can be flipped open to facilitate medication or nursing care. At the same time, the sliding parts can be slid on the mounting table to adjust the distance between the first and second plates and the wound.

[0017] Furthermore, a second handle is rotatably connected to the mounting platform on the left. One end of the second handle is fixedly connected to a first crown wheel. A second crown wheel located below the first crown wheel is slidably connected to the threaded shaft along the axial direction. The second handle transmits torque to the threaded shaft through the engagement of the first and second crown wheels. A retaining ring is fixedly connected to the threaded shaft. A compression spring is connected between the retaining ring and the second crown wheel. The two ends of the compression spring abut against the second crown wheel and the retaining ring, respectively. An annular airbag is installed inside the mounting platform on the left. A pushing ring is installed below the annular airbag and slides inside the mounting platform. The pushing ring is located above the second crown wheel and abuts against the second crown wheel. The pushing ring pushes the second crown wheel downward so that it no longer engages with the first crown wheel.

[0018] With the second handle, threaded shaft, first crown wheel, and second crown wheel, when the second handle rotates, the threaded shaft rotates via the first and second crown wheels, thereby causing the sliding part to move. With the annular airbag, when the annular airbag inflates, the first and second crown wheels disengage, preventing the first and second plates from pressing on the wound.

[0019] Furthermore, both the first and second plates are provided with abutment airbags at their lower ends, which are connected by telescopic pipes. The abutment airbags are used to abut against the periphery of the surgical site, and the abutment airbags and the annular airbags are connected by a second telescopic pipe.

[0020] When the abutment airbag comes into contact with the periphery of the wound, it will compress, which will then cause the annular airbag to expand, thus stopping the first plate and the second plate from moving.

[0021] Furthermore, both the first and second plates are provided with adjustment plates on their lower sides. The airbag is fixedly mounted on the lower end of the adjustment plate. A lead screw shaft and a guide rod are rotatably connected to the adjustment plate. The lead screw shaft and guide rod located on the lower side of the first plate pass through the first plate and are threadedly connected to the first plate. The lead screw shaft and guide rod located on the lower side of the second plate pass through the second plate and are threadedly connected to the second plate.

[0022] By using an adjustment plate, lead screw, and guide rod, the distance between the adjustment plate and the first and second plates can be controlled by blocking the lead screw, thereby adjusting the distance between the first and second plates and the wound site.

[0023] The beneficial effects of this application are as follows:

[0024] 1. The sponge clamping plate and drive assembly are used to fix the sponge clamping plate to the patient's waist. At the same time, the abutment wheel and drive wheel are set. When the clamping force is too large, the abutment wheel and drive wheel will disengage under the action of the inclined surface, so as not to continue to increase the clamping force and avoid causing discomfort to the patient.

[0025] 2. By using the rotating ring and sliding sleeve, when the clamping force needs to be adjusted, the compression degree of the abutment spring can be adjusted by rotating the rotating ring. When the compression degree of the abutment spring is greater, the clamping force on the patient is also greater, which makes it easier for medical staff to control the clamping force on different patients.

[0026] 3. By setting up the abutment airbag, when the abutment airbag comes into contact with the periphery of the wound, the abutment airbag will be compressed, which will then cause the annular airbag to expand, so that the first plate and the second plate will stop moving. By blocking the lead screw shaft, the distance between the adjustment plate and the first plate and the second plate can be controlled, thereby adjusting the distance between the first plate and the second plate and the wound.

[0045] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Reference Figure 1-9A postoperative clinical pressure-resistant protective nursing device includes: a clamping assembly, a baffle 101, a mounting platform 102, a sponge clamping plate 103, an airbag cavity 104, a compression airbag 105, a compression plate 106, a screw 107, a first handle 108, an abutment wheel 109, a transmission wheel 110, and a sliding sleeve 111.

[0047] The clamping assembly includes a base plate 112 and two mounting platforms 102 fixed on the base plate 112 and arranged opposite each other. The mounting platforms 102 and the base plate 112 form a U-shaped structure, and baffles 101 are disposed on the two mounting platforms 102. The baffles 101 include a first plate 113 and a second plate 114. The second plate 114 has a connecting strip 115 that is inserted into and slidably connected to the first plate 113. A limiting screw 116 is threadedly connected to the first plate 113, and one end of the limiting screw 116 abuts against the connecting strip 115 to limit the connection strip 115. By controlling the extension length of the connecting strip 115, the coverage area that the first plate 113 and the second plate 114 can cover can be adjusted.

[0048] In one embodiment, two mounting platforms 102 are each provided with opposing foam clamping plates 103. The two foam clamping plates 103 move relative to each other to clamp the patient's waist for installation. The mounting platform 102 is provided with multiple pairs of vertically distributed sliding rods 117. One end of each sliding rod 117 is inserted into the mounting platform 102 and slides within it. The other end of each sliding rod 117 is connected to the foam clamping plate 103 via a universal ball joint. When clamping, the sliding rod 117 extends out of the mounting platform 102, thus fixing the foam clamping plate 103 in the position of the patient's waist.

[0049] The mounting platform 102 has a mounting cavity 118. One end of the slide rod 117 is inserted into the mounting cavity 118, and an extension airbag 119 is also provided in the mounting cavity 118. When the extension airbag 119 inflates, it will push the slide rod 117 to move, causing the slide rod 117 to extend.

[0050] An airbag cavity 104 is provided in the mounting platform 102 on the right side. A compression airbag 105 is placed in the airbag cavity 104. The compression airbag 105 and the extension airbag 119 are connected through a first telescopic tube 120. When the compression airbag 105 is compressed, the extension airbag 119 is inflated through the first telescopic tube 120.

[0051] A compression plate 106 is slidably connected inside the airbag cavity 104, and the compression plate 106 is located on one side of the compression airbag 105. A screw 107 is rotatably connected inside the airbag cavity 104 and threadedly connected to the compression plate 106. By rotating the screw 107, the compression plate 106 is moved to apply pressure to the compression airbag 105.

[0052] The mounting platform 102 on the left side is also rotatably connected to a first handle 108. The first handle 108 has a shaft portion 121 that is inserted into the mounting platform 102, wherein the shaft portion 121 is coaxially arranged with the screw 107.

[0053] An abutment wheel 109 is axially slidably connected to the shaft 121, and the abutment wheel 109 rotates synchronously with the shaft 121. The abutment wheel 109 is provided with axially protruding transmission teeth in the circumferential direction.

[0054] One end of the screw 107 is fixedly connected to a transmission wheel 110, and the transmission wheel 110 has a tooth groove for the transmission teeth to be inserted.

[0055] When the transmission teeth are engaged in the tooth groove, the abutment wheel 109 can transmit torque to the transmission wheel 110.

[0056] The transmission teeth and tooth grooves have inclined surfaces that abut against each other. When the abutting wheel 109 rotates, it transmits torque to the transmission wheel 110 through the inclined surfaces. Under the action of the inclined surfaces, the abutting wheel 109 tends to move away from the transmission wheel 110. When the abutting wheel 109 moves away from the transmission wheel 110 until the transmission teeth disengage from the tooth grooves, the abutting wheel 109 and the transmission wheel 110 can no longer transmit torque.

[0057] A sliding sleeve 111 is provided on the side of the abutment wheel 109 away from the transmission wheel 110, and the sliding sleeve 111 is slidably disposed within the mounting platform 102. An abutment spring 122 is provided between the sliding sleeve 111 and the abutment wheel 109, and the two ends of the abutment spring 122 abut against the sliding sleeve 111 and the abutment wheel 109 respectively.

[0058] A pushing part 123 is provided on the side of the sliding sleeve 111 away from the abutting wheel 109. The pushing part 123 has a contact surface that extends spirally around the axis and is inclined from near the abutting wheel 109 to away from the abutting wheel 109.

[0059] A rotating ring 124 is rotatably connected inside the mounting platform 102 on the left side, and a push post 125 is fixedly connected to the rotating ring 124 and abuts against the contact surface. When the rotating ring 124 is rotated, the push post 125 and the contact surface act to push the sliding sleeve 111 to move closer to the abutting wheel 109, thereby compressing the abutting spring 122.

[0060] A positioning screw 126 with one end extending out of the mounting platform 102 is threaded onto the rotating ring 124. The mounting platform 102 is also provided with an arc-shaped groove 127 for the positioning screw 126 to pass through. When the end of the positioning screw 126 abuts against the edge of the arc-shaped groove 127, it limits the rotation of the rotating ring 124.

[0061] In this embodiment, when it is necessary to control the clamping force of the sponge clamping plate 103 on the patient, the positioning screw 126 is pushed to rotate the rotating ring 124. This, in turn, causes the sliding sleeve 111 to move and compress the abutment spring 122 under the action of the pushing post 125 and the contact surface. By controlling the rotation angle of the rotating ring 124, the degree of compression of the abutment spring 122 is adjusted, thereby adjusting the clamping force of the sponge clamping plate 103.

[0062] At this time, the abutment wheel 109 receives the thrust of the abutment spring 122, and the transmission teeth are engaged in the tooth groove. When the first handle 108 rotates, it drives the screw 107 to rotate, which in turn causes the compression plate 106 to apply pressure to the compression airbag 105. The first telescopic tube 120 causes the elongated airbag 119 to expand, pushing out the slide rod 117, so that the sponge clamping plate 103 clamps the patient's waist. When a certain clamping force is reached, the compression plate 106 can no longer deform the compression airbag 105, and at this time the screw 107 stops rotating. When the first handle 108 continues to rotate, the abutment wheel 109 moves away from the transmission wheel 110 under the action of the inclined surface and no longer transmits torque.

[0063] In one embodiment, a first plate 113 is slidably disposed on a mounting platform 102 on the left side. The first plate 113 includes a sliding portion 128 slidably disposed on the mounting platform 102 on the left side and a plate-shaped portion 129 hinged to the sliding portion 128. By deflecting the plate-shaped portion 129 relative to the sliding portion 128, the plate-shaped portion 129 has an open and closed state. When in the open state, it facilitates the dressing change operation.

[0064] Both the sliding part 128 and the plate-shaped part 129 are fixedly provided with coaxially arranged limiting sleeves 130. Bolts pass through the two limiting sleeves 130 to limit the sliding part 128 and the plate-shaped part 129. When the bolts are simultaneously inserted into the two limiting sleeves 130, the plate-shaped part 129 is in a closed state. At this time, the plate-shaped part 129 is relatively fixed to the sliding part 128 and moves synchronously with the sliding part 128 to adjust the distance between the first plate 113 and the second plate 114 and the wound.

[0065] A vertically extending sliding groove 131 is provided on the mounting platform 102 on the left side, and the sliding part 128 has a portion that is slidably disposed within the sliding groove 131. A vertically arranged threaded shaft 132 is rotatably connected within the sliding groove 131, and the threaded shaft 132 passes through the portion of the sliding part 128 located within the sliding groove 131 and is threadedly connected to that portion. By rotating the threaded shaft 132, the sliding part 128 is moved, thereby adjusting the distance between the first plate portion and the second plate portion and the wound.

[0066] Adjusting plates 133 are provided on the lower sides of both the first plate 113 and the second plate 114. A lead screw 134 and a guide rod 135 are rotatably connected to the adjusting plate 133. The lead screw 134 and guide rod 135, located on the lower side of the first plate 113, pass through the first plate 113, and the lead screw 134 is threadedly connected to the first plate 113. This allows the adjusting plate 133 to move up and down relative to the first plate 113 by blocking the lead screw 134, thus adjusting the position of the adjusting plate 133. Similarly, the lead screw 134 and guide rod 135, located on the lower side of the second plate 114, pass through the second plate 114, and the lead screw 134 is threadedly connected to the second plate 114. Likewise, rotating the lead screw 134 allows the adjusting plate 133 to move up and down relative to the second plate 114, thus adjusting the position of the adjusting plate 133.

[0067] An abutment airbag 136 is fixedly connected to the lower end of the adjustment plate 133. The abutment airbag 136 is used to contact the outer side of the patient's wound. The two abutment airbags 136 are connected by a corrugated tube.

[0068] A second handle 137 is rotatably connected to the mounting platform 102 on the left side. One end of the second handle 137 is fixedly connected to a first crown wheel 138. A second crown wheel 139 located below the first crown wheel 138 is slidably connected to the threaded shaft 132 along the axial direction. The second handle 137 transmits torque to the threaded shaft 132 through the engagement of the first crown wheel 138 and the second crown wheel 139. Rotating the second handle 137 causes the threaded shaft 132 to rotate under the action of the first crown wheel 138 and the second crown wheel 139, which in turn causes the sliding part 128 to move, adjusting the distance between the first plate 113 and the second plate 114 and the wound.

[0069] A retaining ring 140 is fixedly connected to the threaded shaft 132. A compression spring 141 is connected between the retaining ring 140 and the second crown wheel 139. The two ends of the compression spring 141 abut against the second crown wheel 139 and the retaining ring 140, respectively. Under the action of the compression spring 141, the first crown wheel 138 and the second crown wheel 139 are engaged, thereby transmitting torque.

[0070] An annular airbag 142 is also provided inside the mounting platform 102. A push ring 144 that slides inside the mounting platform 102 is provided on the lower side of the annular airbag 142. When the annular airbag 142 expands, the push ring 144 will move downward.

[0071] The contact airbag 136 and the annular airbag 142 are connected by a second telescopic tube 143. When the contact airbag 136 comes into contact with the patient, the contact airbag 136 is compressed, causing the annular airbag 142 to inflate through the second telescopic tube 143, which in turn causes the push ring 144 to move.

[0072] The push ring 144 is located above and abuts against the second crown wheel 139. When the push ring 144 moves downward, it drives the second crown wheel 139 downward, so that it is no longer engaged with the first crown wheel 138. At this time, the first crown wheel 138 and the second crown wheel 139 no longer transmit torque.

[0073] Both the first telescopic tube 120 and the second telescopic tube 143 are corrugated pipes.

[0074] In this embodiment, when it is necessary to adjust the distance between the first plate 113 and the second plate 114 and the wound, the distance between the abutment spring 122 and the first plate 113 and the second plate 114 is adjusted by rotating the lead screw shaft 134. When the second handle 137 is rotated, the first plate 113 and the second plate 114 will move downwards through the sliding part 128. When the abutment airbag 136 contacts the patient, it is compressed, and the annular airbag 142 inflates through the second telescopic tube 143. At this time, the push ring 144 pushes the second crown wheel 139, and the second crown wheel 139 and the first crown wheel 138 are no longer engaged. The first plate 113 and the second plate 114 can no longer move downwards, avoiding pressure on the wound.

[0075] Usage instructions or work process:

[0076] 1. The patient lies on the base plate 112 between the two mounting platforms 102. The first plate 113 and the second plate 114 are positioned above the wound, providing cover and protection. Rotating the first handle 108 causes the screw 107 to rotate under the action of the abutment wheel 109 and the transmission wheel 110. This causes the compression plate 106 to apply pressure to the compression airbag 105, compressing it. Through the first telescopic tube 120, the extended airbag 119 pushes out the slide rod 117, allowing the sponge clamping plate 103 to clamp the patient's waist. When a certain clamping force is reached, the inclined surface of the transmission teeth and grooves causes the abutment wheel 109 to move away from the transmission wheel 110, simultaneously compressing the abutment spring 122, causing the transmission teeth to disengage from the grooves. At this point, the screw 107 stops rotating, ceasing clamping. When adjusting the clamping force, the positioning screw 126 is pushed, causing the rotating ring 124 to rotate. Then, under the action of the pushing column 125 and the contact surface, the sliding sleeve 111 moves and compresses the abutment spring 122. By controlling the rotation angle of the rotating ring 124, the degree of compression of the abutment spring 122 is adjusted, thereby adjusting the clamping force of the sponge clamping plate 103.

[0077] 2. When it is necessary to adjust the distance between the first plate 113 and the second plate 114 and the wound location, rotating the second handle 137 causes the threaded shaft 132 to rotate via the first crown wheel 138 and the second crown wheel 139. This causes the sliding part 128 to move downwards, which in turn causes the first plate 113 and the second plate 114 to move downwards. When the contact airbag 136 contacts the patient, the contact airbag 136 is compressed, causing the annular airbag 142 to inflate via the second telescopic tube 143. This causes the pushing ring 144 to move. When the pushing ring 144 moves downwards, it causes the second crown wheel 139 to move downwards, so that it no longer engages with the first crown wheel 138. At this point, torque is no longer transmitted, and the first plate 113 and the second plate 114 no longer move downwards, thus avoiding pressure on the wound location.
