Description

Technical Field

[0001] The invention relates to the technical field of nursing equipment, and in particular to a field medical lying position pressure sore nursing equipment. Background Art

[0002] Patients who are bedridden for a long time are prone to pressure sores. To address this problem, many devices for nursing patients who are used to turn over the injured have emerged. The main working parts of such devices are basically in the design of the turning structure. By setting a turning structure on the nursing bed, the turning structure can assist the injured in turning over while they are in bed, so as to achieve care and prevent the occurrence of pressure sores.

[0003] However, for some special occasions, such as field battles, stretchers are the most commonly used medical tools. The stretchers used in field battles must also have a folding function so that they can be carried with them and used at any time during the transfer process. The injured are placed on the stretcher for transfer. In this case, the existing supine pressure sore care equipment is difficult to apply to field medical use. The reason is that the turning structure in the prior art needs to be installed on a fixed rigid bed or a rigid support structure, and a relatively stable and wide rigid support bed or a rigid support structure is required to assist the wounded in turning over. The stretchers suitable for field battles are relatively simple and thin and need to be folded at any time. The stability and supporting capacity of this stretcher cannot match the above-mentioned turning structure. The wounded can only be transferred by stretcher, and the pressure sores on the wounded may continue to contact the stretcher during the transfer process, resulting in severe pressure sores. If the wounded still have wounds on their bodies, the wounds cannot continue to contact the stretcher, otherwise the wounds may worsen. Summary of the invention

DETAILED DESCRIPTION

[0035] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0036] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Patients who are bedridden for a long time are prone to pressure sores. Pressure sores are generally caused by long-term vertical pressure, shear force, and friction on the skin. Therefore, the prevention and care of pressure sores focus on preventing the skin from being under pressure for a long time and keeping it breathable. To address this problem, many supine pressure sore care devices have emerged. The main working parts of this type of supine pressure sore care device are basically in the design of the turning structure. By arranging a turning structure on the nursing bed, the turning structure can assist the patient to turn over while in bed, so as to achieve care and prevent the occurrence of pressure sores.

[0038] However, for some special use places such as field battles, stretchers are the most commonly used medical tools. Currently, the stretchers used in field battles are roughly as follows: Figure 1 As shown, the stretcher 1 includes two fixing rods 20, a canvas 21 is fixed between the two fixing rods 20, a handle 22 is sleeved on the part of the two fixing rods 20 extending out of the canvas 21, and a supporting leg 23 is fixed to the bottom of the two fixing rods 20 near the handle 22. The injured person is placed on the stretcher 2 for transfer. In this case, the existing lying pressure sore care equipment is difficult to be used in field medical treatment. The reason is that the turning structure in the prior art needs to be installed on a fixed rigid bed or rigid support structure, and a relatively stable and wide rigid support bed or rigid support structure is required to assist the wounded in turning over. The stretchers suitable for field combat are relatively simple and thin and need to be folded at any time. The stability and supporting capacity of this stretcher cannot match the above-mentioned turning structure. The wounded can only be transferred by stretcher, and the pressure sores on the wounded may continue to contact the stretcher during the transfer process, resulting in severe pressure sores. If the wounded still have wounds on their bodies, the wounds cannot continue to contact the stretcher, otherwise the wounds may worsen.

[0039] To this end, an embodiment of the present invention provides a field medical supine pressure sore care device, which can be well matched and installed on a field folding stretcher to provide local support to the parts near the pressure sores or wounds of the wounded, thereby ensuring that the supine pressure sores or wounds are not squeezed in the field environment.

[0040] At least one embodiment of the present invention provides a field medical supine pressure sore care device, comprising: an inflatable cushion, a longitudinal moving assembly and a support bracket, the inflatable cushion having an inflation and deflation port, the inflatable cushion being configured to be connected to a stretcher, the shape of the inflatable cushion matching the stretcher, the longitudinal moving assembly being located in the inflatable cushion, the longitudinal moving assembly comprising: two fixed pulleys and a rope loop wound around the two fixed pulleys, the two fixed pulleys being symmetrically mounted in the inflatable cushion, the two fixed pulleys being arranged along the length direction of the inflatable cushion, one of the fixed pulleys being connected to a driving member to rotate the fixed pulley, thereby driving the rope loop to move along the length direction of the inflatable cushion, the support bracket being fixedly connected to the rope loop, and when the inflatable cushion is in an uninflated state, the support bracket props up the inflatable cushion that is in direct contact with the support bracket.

[0041] In the field medical supine pressure sore nursing equipment provided by the above-mentioned embodiment of the present invention, by designing the overall load-bearing part of the equipment into an inflatable cushion form, the overall weight of the equipment will be lighter and can be adapted for field medical use; by fixing the inflatable cushion on a stretcher, it can be used in conjunction with the stretcher during field operations; when folding the stretcher, the inflatable cushion can be deflated and folded up together with the stretcher and carried around; when transferring a wounded person, the wounded person lies on the inflatable cushion, and the inflation and deflation port is opened first to discharge part of the air in the inflatable cushion to make the inflatable cushion concave; the fixed pulley can be rotated by the driving member on the longitudinal moving assembly, thereby rotating the rope loop to adjust the position of the support on the inflatable cushion so that it supports the vicinity of the pressure sore or wound of the wounded person, thereby It can lift the pressure sore or injured part of the wounded, relieve pressure and ventilate the pressure sore or injured part, and provide care. In addition, if the support bracket is moved at a uniform speed, it can massage the back of the body and increase blood flow rate, which can further avoid the occurrence of new pressure sores and also provide care for the pressure sore position to prevent it from worsening. Even in the process of transferring the wounded in the field, the inflatable cushion can be adjusted, folded and transferred at any time with the stretcher to ensure that the wounded receive timely care. At the same time, the longitudinal moving assembly composed of a fixed pulley and a rope loop cooperates with the inflatable cushion to ensure that the movement of the support bracket can be guaranteed and it can also be folded together with the inflatable cushion when the stretcher is folded, so that it is suitable for carrying and use at any time in the field.

[0042] The present invention is described below by several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one accompanying drawings, the component may be represented by the same reference numeral in each of the accompanying drawings.

[0043] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 2 The overall structural diagram of a field medical supine pressure sore nursing device provided by an embodiment of the present invention is as follows: Figure 3 A schematic diagram of the overall structure of a field medical supine pressure sore nursing device provided by an embodiment of the present invention when in use, Figure 4 for Figure 2 Sectional view along AA direction, Figure 5 for Figure 2 Cross-sectional view along the BB axis. Figure 6 for Figure 4 The enlarged schematic diagram of the local structure at G in the middle is as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an embodiment of the present invention provides a field medical lying position pressure sore nursing equipment, including: an inflatable cushion 10, a longitudinal moving assembly 11 and a support bracket 13, the inflatable cushion 10 has an air filling and discharging port, the inflatable cushion 10 is configured to be connected to the stretcher 2, the shape of the inflatable cushion 10 matches the stretcher 2, the longitudinal moving assembly 11 is located in the inflatable cushion 10, and the longitudinal moving assembly 11 includes: two fixed pulleys 110 and a rope loop 111 wound around the two fixed pulleys 110, the two fixed pulleys 110 are symmetrically installed in the inflatable cushion 10, the two fixed pulleys 110 are arranged along the length direction of the inflatable cushion 10, one of the fixed pulleys 110 is connected to the driving member 112, so that the fixed pulley 110 rotates, thereby driving the rope loop 111 to move along the length direction of the inflatable cushion 10, and the support bracket 13 is fixedly connected to the rope loop 111, and when the inflatable cushion 10 is not inflated, the support bracket 13 supports the inflatable cushion 10 directly in contact with the support bracket 13. .

[0044] It should be understood that the upper surface of the inflatable cushion 10 should be made of a softer material, such as a softer rubber material, and a layer of breathable mesh can be added to the upper surface of the inflatable cushion 10, so that when supporting a certain part of the body, the injured person's body can directly contact the inflatable mesh to increase breathability. A connector made of rigid material is added to the inflatable cushion 10, so that the longitudinal moving component 11 can be stably connected to the inflatable cushion 10. The longitudinal moving component 11 can be any mechanism that can achieve linear displacement, such as the commonly used gear rack structure, slide rail slider mechanism, connecting rod mechanism, screw nut mechanism, etc. However, considering the special practical occasions such as field combat, it is necessary to transfer at any time and all equipment needs to be easy to carry. Therefore, the longitudinal moving component 11 in the embodiment of the present invention adopts the form of a fixed pulley 110 and a rope loop 111, so that when folding When folded, the steel cable 11 can be folded and suitable for use as a stretcher in the field. The support bracket 13 can be driven by the longitudinal moving component 11 to move along the length direction of the inflatable cushion 10, which is suitable for supporting various parts of the wounded in the field lying position, so that various parts of the body can reduce the direct pressure on the bed, and play a role in pressure sore care. When there is no need to support a certain part of the body, the inflatable cushion 10 can be filled with air. At this time, the support bracket 13 will not protrude from the surface of the inflatable cushion 10, and it can be fixed on the stretcher like an inflatable mattress, and can also be removed when it is not needed. After deflation, it can be folded or folded together with the stretcher for easy carrying in the field. The connection between the inflatable cushion 10 and the stretcher 1 can be provided with straps or Velcro around the inflatable cushion 10, and the straps or Velcro can be wrapped around the fixing rod 20 to achieve the fixation of the two.

[0045] The field medical supine pressure sore nursing equipment provided by the embodiment of the present invention designs the entire load-bearing part of the equipment into an inflatable cushion form, so that the overall weight of the equipment will be lighter and can be adapted for field medical use; by fixing the inflatable cushion on a stretcher, the equipment can be used in conjunction with the stretcher during field operations; when folding the stretcher, the inflatable cushion can be deflated and then folded up together with the stretcher and carried around; when transferring a wounded person, the wounded person lies on the inflatable cushion, and the inflation and deflation ports are first opened to discharge part of the air in the inflatable cushion to make the inflatable cushion concave; the fixed pulley can be rotated by the driving member on the longitudinal moving assembly, thereby rotating the rope loop to adjust the position of the support on the inflatable cushion so that it is supported near the pressure sore or wound of the wounded person, thereby being able to It can lift the pressure sore or injured part of the wounded, relieve pressure and ventilate the pressure sore or injured part, and provide care. In addition, if the support bracket is moved at a uniform speed, it can massage the back of the body, increase blood flow rate, further avoid the occurrence of new pressure sores, and care for the pressure sore position to prevent it from worsening. Even in the process of transferring the wounded in the field, the inflatable cushion can be adjusted, folded and transferred at any time with the stretcher to ensure that the wounded receive timely care. At the same time, the longitudinal moving assembly composed of a fixed pulley and a rope loop cooperates with the inflatable cushion to ensure that the movement of the support bracket can be guaranteed and it can also be folded in conjunction with the inflatable cushion when the stretcher is folded, so that it is suitable for carrying and use at any time in the field.

[0046] Considering that the wounded are weak after being injured, and in a field environment, the wounded often need to be transferred, therefore, more consideration needs to be given to whether the support brace 13 can better cooperate with the wounded body.

[0047] Based on the above problems, refer to Figure 7 , Figure 7 A cross-sectional view of a support bracket provided in the first embodiment of the present invention, as shown in FIG. Figure 7 As shown, in the field medical supine pressure sore nursing equipment provided by the embodiment of the present invention, the support bracket 13 includes: a main body 130 and a support surface 131, the main body 130 is connected to the longitudinal movable end 121, the support surface 131 is fixedly connected to the side of the main body 130 away from the longitudinal movable end 121, the support surface 131 is an arc-shaped structure as a whole, and the arc-shaped structure protrudes toward the side away from the main body 130, so that the main body 130 plays an overall supporting role to ensure a certain supporting strength, and the part that supports the body, that is, the support surface 131, is designed to be an arc-shaped structure, so that the part of the inflatable cushion 10 that is supported can be an arc-shaped structure, that is, the part of the inflatable cushion 10 that contacts the body has an arc, rather than a straight ridge line, so that even if the wounded person's body moves due to shaking during the field transfer process, it will not produce a hard collision with the protruding part of the inflatable cushion 10, thereby avoiding further injury to the wounded person or impact on the pressure sore site, thereby increasing comfort.

[0048] refer to Figure 8 , Figure 8A cross-sectional view of a support bracket provided for a second embodiment of the present invention, as shown in FIG. Figure 8 As shown, the top of the support surface 131 is a planar structure. The reason why the top of the support surface 131 is a planar structure is to reduce the pressure on the contact part of the injured person in the case of surface contact and avoid the discomfort caused by point contact. It should also be noted that the smooth transition between the planar structure on the top of the support surface 131 and the arc-shaped structure on the side of the support surface 131 further reduces the impact and collision with the injured person's part, and can also have a smaller impact on the supported inflatable cushion 10.

[0049] Reference again Figure 8 The side of the support surface 131 facing away from the main body 130 has a plurality of protrusions 135, and the plurality of protrusions 135 are arranged in an array. The plurality of protrusions 135 can play a certain massage role, thereby playing an obvious massage role during the movement of the support bracket 3, thereby further promoting the blood circulation of the wounded, further avoiding the occurrence of new pressure sores, and also caring for the position of the pressure sores to prevent them from worsening.

[0050] Reference again Figure 8 A cavity 132 is formed between the body 130 and the support surface 131, and the support surface 131 is made of a flexible material. A support component is connected in the cavity 132, and the support component supports the support surface 131. A cavity 132 is formed between the body 130 and the support surface 131, and the support surface 131 is made of a flexible material. In this way, the support surface 131 can have a certain deformation, which can adapt to the shape of various positions of the body when the body moves relative to the inflatable cushion 10 during the transfer during the field battle, and the rigid support is changed into a flexible support, so that the wounded are more comfortable. In addition, the support support 13 moves During the process, the shape of the support surface 131 can be changed according to the softness of the body parts (such as the different hardness of the bone and muscle parts), so as to avoid hard collision with the injured part or the pressure sore part of the injured person. The support component connected in the cavity 132 can provide a certain support for the support surface 131, so as to avoid the support surface 131 being too low and unable to support a part of the body, and further ensure that various parts of the injured person's back can be lifted in turn, so that the pressure sore or injured part can be separated from the surface of the inflatable cushion, so that these places will not be compressed and keep ventilated, thereby preventing the occurrence of pressure sores.

[0051] Specifically, in an embodiment of the present invention, the support assembly includes: a spring 133 and a scissors-link structure 134, one end of the spring 133 is fixed to the main body 130, and the other end is fixed to the support surface 131, the extension and retraction direction of the spring 133 is consistent with the height direction of the main body 130, the scissors-link structure 134 is located in the spring 133, one end of the scissors-link structure 134 is rotatably connected to the main body 130, and the other end is rotatably connected to the support surface 131, and the extension and retraction direction of the scissors-link structure 134 is consistent with the spring 133.

[0052] The scissor-type connecting rod structure 134 includes a plurality of connecting rods. It should be understood that spring seats are fixed at both ends of the spring 133, and the spring seats are respectively fixed on the support surface 131 and the bottom of the body 130. The spring 133 is supported by the spring seat, and a plurality of connecting rods pivoted in sequence are connected inside the spring. The plurality of connecting rods are relatively loose and present a scissor-type structure. The connecting rods at the top and the bottom are both connected to the corresponding spring seats. The spring 133 can play an elastic supporting role on the support surface 131, and can further adapt to the shape of various positions of the body when the body moves relative to the inflatable cushion 10 during transfer during field combat, and change the rigid support into a flexible support to make the wounded more comfortable. In addition, the support bracket 13 can be adjusted according to the softness of the body parts (such as the different hardness of the bone and muscle parts) during movement. ) changes the shape of the support surface 131 to avoid hard collision with the injured person's body, and a support component is connected in the cavity 132 to provide certain support for the support surface 131, to avoid the support surface 131 being too low and unable to support a certain part of the body, and to further ensure that various parts of the injured person's back can be lifted in turn, so that the neck and the heel of the neck can be separated from the surface of the inflatable cushion, so that these places will not be compressed and can remain ventilated, thereby preventing the occurrence of pressure sores. The scissor-type connecting rod structure 134 can guide the spring 133, to avoid the spring 133 from tilting during the extension and contraction process and thus losing support for the support surface 131. In addition, the scissor-type connecting rod structure 134 can provide certain rigid support, to further avoid crushing the spring 133 and ensure appropriate elastic support.

[0053] Reference again Figure 2 A bottom support air cushion 14 is connected between the inflatable cushion 10 and the stretcher 2. The bottom support air cushion 14 has an inflation and deflation port. The top surface shape of the bottom support air cushion 14 matches the bottom surface shape of the inflatable cushion 10. Considering that the stretcher often cannot be completely stretched during the transfer process and is generally concave toward the middle position, when caring for the wounded, after the inflatable cushion 10 is deflated, it also collapses, and the support is poor. It may not be possible to support the top surface of the support bracket 13 on the surface of the inflatable cushion, thereby failing to support the pressure sores or wounds of the wounded. Therefore, when the inflatable cushion 10 is deflated, the top surface of the support bracket 13 may not be supported on the surface of the inflatable cushion, and thus the pressure sores or wounds of the wounded cannot be supported. A bottom supporting air cushion 14 is connected between the pad 10 and the stretcher 2. Straps or Velcro can be set around the bottom supporting air cushion 14. The straps or Velcro can be wrapped around the fixing rod 20 to fix the two. Then the bottom of the inflatable cushion 10 and the top surface of the bottom supporting air cushion 14 are completely fitted together by Velcro. After the bottom supporting air cushion 14 is filled with air, the air can support the bottom of the inflatable cushion 10, thereby further supporting the supporting bracket 13, ensuring that it can support the injured person, so that the pressure sore or wound area is separated from the surface of the inflatable cushion 10, and playing a nursing role.

[0054] Considering that the support bracket 13 can be moved at any time at any position as much as possible, refer again to Figure 4 , Figure 5 , Figure 6 and Fig. 9 ,in, Fig. 9 for Figure 5 The enlarged schematic diagram of the local structure at H in the middle shows that the field medical supine pressure sore nursing equipment in the embodiment of the present invention also includes lateral movement components 12 respectively connected to the inner side walls in the width direction of the inflatable cushion 10, each group of lateral movement components 12 includes: a support frame 120, a screw 121 and a nut seat 122, the support frame 120 is U-shaped, the support frame 120 is fixed to the bottom of the side wall in the width direction of the inflatable cushion 10, the screw 121 is arranged along the width direction of the inflatable cushion 10, one end of the screw 121 is rotatably connected to the side wall of the support frame 120, and the other end of the screw 121 passes through the support frame 120 and the side wall of the inflatable cushion 10 and extends out of the inflatable cushion 10, the nut seat 122 is screwed to the screw 121, and the bottom of the nut seat 122 is slidably matched with the bottom of the support frame 120 along the width direction of the inflatable cushion 10, and the fixed pulley 110 is connected to the nut seat 122 one by one.

[0055] The lead screw 121 and the side wall of the support frame 120 are rotationally connected through a self-locking bearing 124. Considering that it is inconvenient to use electronic components during field use, the part of the lead screw 121 extending out of the inflatable cushion 10 is fixed with a rotating handle 123. When in use, the lead screw 121 is rotated by rotating the rotating handle 123, thereby driving the fixed pulley 110 to move, so that the support bracket 13 can move laterally. It should be noted that the connection part between the self-locking bearing 124 and the inflatable cushion 10 needs to be sealed, such as through a sealing ring. The bottom of the support frame 120 plays a guiding role. The bottom of the support frame 120 is provided with a slide groove along the width direction of the inflatable cushion 10, and the bottom of the nut seat 122 is slidably matched with the slide groove. In this way, on the one hand, the fixed pulley 110 can move with the lateral movement of the nut seat 122 while also completing the longitudinal movement.

[0056] When folding, both the inflatable cushion 10 and the bottom supporting air cushion 14 are deflated, and the two are folded along the width direction of the inflatable cushion 10 .

[0057] In the embodiments of the present invention, specific reference is made to Fig. 9The driving member 112 includes a telescopic rod, which is arranged along the width direction of the inflatable cushion 10, one end of the telescopic rod is fixedly connected to the center of the fixed pulley 110, and the other end of the telescopic rod passes through the side wall of the support frame 120 and extends out of the side wall of the inflatable cushion 10. The driving member 112 is set to a telescopic rod. When the fixed pulley 110 moves laterally with the nut seat 122, the telescopic rod can be extended and retracted to cooperate with it as the position changes. Considering field use, the telescopic rod is connected to the side wall of the support frame 120 through a self-locking bearing, the telescopic rod is sealed with the side wall of the inflatable cushion 10, and the telescopic rod extends out of the part of the inflatable cushion 10 to fix the hand wheel 113. When in use, longitudinal movement is achieved by turning the hand wheel 113. It should also be noted that the fixed pulley 110 is rotatably connected to the fixed frame 114, and the fixed frame 114 and the nut seat are fixed.

[0058] In an embodiment of the present invention, the side of the inflatable cushion 10 facing away from the stretcher 2 is a flexible surface. When the inflatable cushion 10 is in a recessed state, the flexible surface can prevent the portion of the inflatable cushion 10 supported by the support bracket 13 from being overly stretched with other areas, that is, other portions of the inflatable cushion 10 that are not in contact with the body are relatively collapsed, thereby minimizing the contact area between the body and the inflatable cushion 10 to the greatest extent possible. The pressure on the non-contact parts of the body is released, further avoiding the occurrence of pressure sores. For example, a softer rubber material can be used, and a layer of breathable mesh can be added to the upper surface of the inflatable cushion 10. In this way, when a certain part of the body is supported, the injured person's body can be in direct contact with the breathable mesh to increase breathability.

[0059] Taking into account the comprehensive consideration of support height and comfort, when the inflatable cushion 10 is in an uninflated state, the height difference between the highest and lowest points of the inflatable cushion 10 is 3cm-5cm. If the support height is lower than 3CM, the distance between the other parts of the body that are not in contact with the inflatable cushion 10 and the inflatable cushion 10 is small, the air permeability is not very good, and pressure sores are prone to occur. If the support height is greater than 5CM, the distance between the other parts of the body that are not in contact with the inflatable cushion 10 and the inflatable cushion 10 is large, the squeezing effect on the contact part is obvious, which can easily lead to congestion.

[0060] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
