Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nursing equipment, in particular to a field medical bed position pressure sore nursing equipment. BACKGROUND

[0002] Long-term bedridden wounded people are prone to pressure sores, and many bed position pressure sore nursing equipment for wounded personnel turning over have appeared to solve this problem. The main working components of this kind of bed position pressure sore nursing equipment are basically in the design of turning over structure. By setting the turning over structure on the nursing bed, the wounded person can be assisted to turn over through the turning over structure when lying on the bed to achieve nursing and prevent the occurrence of pressure sores.

[0003] However, for some special occasions, such as field operations, stretchers are the most commonly used medical tools. The stretchers used in field operations must also have folding functions, so that they can be carried with them to meet the needs of immediate use during the transfer process. The wounded person is placed on the stretcher for transfer. In this case, the existing bed position pressure sore nursing equipment is not suitable for field medical use. The reason is that the turning over structure in the prior art needs to be installed on a fixed rigid bed body or a rigid support structure. A relatively stable and wide rigid support bed body or a rigid support structure is needed to achieve the assisted turning over of the wounded person. The stretchers used in field operations are relatively simple and light and need to be folded at any time. The stability and support capacity of such stretchers cannot match the above-mentioned turning over structure. The wounded person can only be transferred by the stretcher during the transfer process. However, the pressure sores on the wounded person's body may continue to contact the stretcher during the transfer process, resulting in severe pressure sores. If the wounded person has a wound, the wound cannot continuously contact the stretcher, otherwise the wound may worsen. SUMMARY

DETAILED DESCRIPTION

[0035] One specific embodiment of the present application will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present application is not limited by the specific embodiment.

[0036] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the technical solutions of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0037] Long-term bedridden patients are prone to pressure sores, and the causes of pressure sores are generally due to long-term vertical pressure, shear force and friction on the skin. Therefore, the focus of pressure sore prevention and care is to prevent the skin from being pressed for a long time and to maintain ventilation. In view of this problem, many bed position pressure sore nursing devices have appeared. The main working parts of this type of bed position pressure sore nursing device are basically in the design of a turning structure. By setting a turning structure on the nursing bed, the patient can be assisted to turn over by the turning structure when lying in bed to achieve nursing and prevent pressure sores.

[0038] But for some special use places such as field operations, the stretcher is the most commonly used medical tool, and the stretcher used in field operations at present is roughly shown in Figure 1 The stretcher 1 includes two fixed rods 20, a canvas 21 fixed between the two fixed rods 20, a handle sleeve 22 sleeved on the part of the two fixed rods 20 extending out of the canvas 21, and a support leg 23 fixed to the bottom of the part of the two fixed rods 20 close to the handle sleeve 22. The wounded wounded person is placed on the stretcher 2 for transfer. In this case, the existing recumbent pressure sore nursing equipment is more difficult to be used in field operations. The reason is that the turning-over structure in the prior art needs to be installed on a fixed rigid bed body or a rigid support structure, and a relatively stable and wide rigid support bed body or a rigid support structure is needed to realize the auxiliary turning-over of the wounded person. The stretcher suitable for field operations is relatively simple and light and needs to be folded at any time. The stability and support capacity of the stretcher cannot match the turning-over structure. The wounded person can only be transferred by the stretcher during the transfer. The pressure sore on the wounded person may continuously contact the stretcher during the transfer, which may cause the pressure sore to be serious. If the wounded person has a wound, the wound cannot continuously contact the stretcher, otherwise the wound may be aggravated.

[0039] Therefore, the embodiment of the present application provides a field operation medical recumbent pressure sore nursing equipment which can be well matched and installed on a field operation folding stretcher, and locally supports the part near the pressure sore or the part near the wound of the wounded person, so as to ensure that the recumbent pressure sore or the wound is not pressed in the field operation environment.

[0040] The embodiment of the present application provides a field operation medical recumbent pressure sore nursing equipment, which comprises an inflatable pad, a longitudinal moving assembly and a support bracket. The inflatable pad has a charging and discharging port and is configured to be connected to a stretcher. The shape of the inflatable pad is matched with the stretcher. The longitudinal moving assembly is located in the inflatable pad. The longitudinal moving assembly comprises two fixed pulleys and a rope ring wound on the two fixed pulleys. The two fixed pulleys are symmetrically installed in the inflatable pad and are arranged along the length direction of the inflatable pad. One of the two fixed pulleys is connected with a driving member to make the fixed pulley rotate and drive the rope ring to move along the length direction of the inflatable pad. The support bracket is fixedly connected to the rope ring. When the inflatable pad is in an unfilled state, the support bracket supports the part of the inflatable pad directly contacting 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 entire 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 the stretcher, it can be used in conjunction with the stretcher during field operations. When folding the stretcher, the inflatable cushion can be folded up together with the stretcher after deflating. When transferring the wounded, the wounded lies on the inflatable cushion, first open the inflation and deflation port to discharge part of the air in the inflatable cushion to make the inflatable cushion concave, and the driving part on the longitudinal moving assembly can rotate the fixed pulley, thereby rotating the rope loop to adjust the position of the support on the inflatable cushion so that it supports the wounded near the pressure sore or wound. 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 also provide care for the pressure sore position to prevent it from worsening. Even in the process of transferring 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 component 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 means of several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numeral in each drawing.

[0043] refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , Figure 2 This is a schematic diagram of the overall structure of a field medical supine pressure ulcer care device provided by an embodiment of the present invention. Figure 3 This is a schematic diagram of the overall structure of a field medical supine pressure ulcer care device in use provided by an embodiment of the present invention. Figure 4 for Figure 2 The cross-sectional view along the AA direction, Figure 5 for Figure 2 Cross-sectional view along the BB direction, 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, the field medical bedsores nursing equipment provided by the embodiment of the present application comprises: an inflatable pad 10, a longitudinal moving assembly 11 and a support 13, the inflatable pad 10 is provided with a charging and discharging port, the inflatable pad 10 is configured to be connected to a stretcher 2, the shape of the inflatable pad 10 is matched with the stretcher 2, the longitudinal moving assembly 11 is located in the inflatable pad 10, the longitudinal moving assembly 11 comprises: two fixed pulleys 110 and a rope ring 111 arranged on the two fixed pulleys 110, the two fixed pulleys 110 are symmetrically installed in the inflatable pad 10, the two fixed pulleys 110 are arranged along the length direction of the inflatable pad 10, one of the two fixed pulleys 110 is connected with a driving member 112, so that the fixed pulley 110 rotates, thereby driving the rope ring 111 to move along the length direction of the inflatable pad 10, the support 13 is fixedly connected to the rope ring 111, when the inflatable pad 10 is in an uncharged state, the support 13 supports the part of the inflatable pad 10 directly contacted with the support 13.

[0044] It should be understood that the upper surface of the inflatable pad 10 should be made of soft material, such as soft rubber material, and a breathable mesh can be added to the upper surface of the inflatable pad 10, so that when supporting a part of the body, the wounded body directly contacts with the breathable mesh, thereby increasing the breathability, and a connecting piece made of rigid material is arranged in the inflatable pad 10, so that the longitudinal moving assembly 11 can be stably connected in the inflatable pad 10, the longitudinal moving assembly 11 can be a mechanism capable of realizing linear displacement, such as a common gear and rack structure, a slide rail and slide block mechanism, a connecting rod mechanism, a screw and nut mechanism, etc., but considering the special practical situation of field operation, it is necessary to transfer at any time, and all equipment needs to be conveniently carried, therefore, the longitudinal moving assembly 11 in the embodiment of the present application adopts the form of the fixed pulley 110 and the rope ring 111, so that the steel rope 11 can be folded when being folded, thereby adapting to the use of the stretcher in field operation, the support 13 can be driven by the longitudinal moving assembly 11 to move along the length direction of the inflatable pad 10, thereby adapting to the support of each part of the wounded in field operation, so that each part of the body can reduce the direct pressure on the bed, thereby playing a pressure sore nursing role, when it is not necessary to support a part of the body, the inflatable pad 10 can be fully charged, so that the support 13 does not protrude from the surface of the inflatable pad 10 at this time, which is similar to the inflatable mattress fixed on the stretcher, and the inflatable pad 10 can also be detached when not in use, folded after being deflated or folded together with the stretcher for storage, thereby facilitating the carrying in field operation, the connection between the inflatable pad 10 and the stretcher 1 can be achieved by arranging a bandage or a magic tape around the inflatable pad 10 and winding the bandage or the magic tape on the fixed rod 20.

[0045] The wild field medical lying position pressure sore nursing equipment provided by the embodiment of the present application has the following advantages: the whole device is designed as an inflatable pad, so that the whole device is light in weight and can be used in wild field medical treatment; the inflatable pad is fixed on a stretcher, so that the inflatable pad can be used with the stretcher in the wild field; when the stretcher is folded, the inflatable pad can be deflated and folded together with the stretcher for carrying; when the wounded person is transferred, the wounded person lies on the inflatable pad, the inflation outlet is opened to deflate the inflatable pad to make the inflatable pad concave, the driving member on the longitudinal moving assembly is driven to rotate the fixed pulley, so that the rope ring is rotated to adjust the position of the support bracket on the inflatable pad, and the support bracket is supported near the pressure sore or the wound of the wounded person, so that the pressure sore or the wounded part of the wounded person is lifted, the pressure on the pressure sore or the wounded part is released, and the pressure sore or the wounded part is ventilated and nursed; in addition, if the support bracket is moved at a constant speed, the back of the body can be massaged, the blood flow speed is increased, new pressure sores can be further avoided, the pressure sore position can be nursed, and the pressure sore position cannot be worsened; even in the process of transferring the wounded person in the wild field, the inflatable pad can be adjusted and folded with the stretcher at any time, so that the wounded person can be nursed in time, and the inflatable pad can be folded with the stretcher at any time, so that the inflatable pad can be carried and used at any time in the wild field.

[0046] Considering that the wounded person is weak after being wounded, and the wounded person needs to be transferred in the wild field, the support bracket 13 needs to be better adapted to the wounded person.

[0047] Based on the above problems, reference is made to Figure 7 , Figure 7 The support bracket provided by the first embodiment of the present application has the following advantages: as shown in the sectional view of the support bracket, Figure 7 In the wild field medical lying position pressure sore nursing equipment provided by the embodiment of the present application, the support bracket 13 comprises a body 130 and a support surface 131, the body 130 is connected with the longitudinal moving end 121, and the support surface 131 is fixed to one side of the body 130 away from the longitudinal moving end 121; the support surface 131 is in an arc structure as a whole, and the arc structure is convex to the side away from the body 130; in this way, the body 130 plays a role in supporting as a whole to ensure a certain supporting strength, and the part of the body that supports the body, that is, the support surface 131, is designed as an arc structure, so that the part of the inflatable pad 10 that is supported is in an arc structure, that is, the part of the inflatable pad 10 that contacts the body has an arc, instead of a straight line; in this way, even if the body of the wounded person moves due to shaking and the like in the process of transferring in the wild field, the body of the wounded person will not collide with the convex part of the inflatable pad 10, so as to avoid further injury to the wounded person or impact on the pressure sore part, and increase comfort.

[0048] Reference is made to Figure 8 , Figure 8A sectional view of the support bracket provided for the second embodiment of the present application is shown in Figure 8 The top of the support surface 131 is in a planar structure, which is designed to reduce the pressure on the contact part of the wounded person in the case of surface contact, and to avoid the discomfort caused by point contact. It is to be noted that the planar structure of the top of the support surface 131 is smoothly connected with the arc-shaped structure of the side of the support surface 131, which further reduces the impact collision with the part of the wounded person, and also has a small impact on the inflatable cushion 10.

[0049] Referring again to Figure 8 , the side of the support surface 131 away from the body 130 has a plurality of protrusions 135 arranged in an array, which can have a certain massage effect, thereby significantly improving the massage effect during the movement of the support bracket 3, further promoting the blood circulation of the wounded person, and further avoiding the generation of new pressure sores, and also nursing the pressure sores to prevent them from worsening.

[0050] Referring again to Figure 8 , the cavity 132 is formed between the body 130 and the support surface 131, the support surface 131 is made of flexible material, and the support assembly is connected in the cavity 132. The support assembly supports the support surface 131. The cavity 132 is formed between the body 130 and the support surface 131, and the support surface 131 is made of flexible material, which can make the support surface 131 have a certain deformation, adapt to the shape of each position of the body during the movement of the body relative to the inflatable cushion 10 during the transfer in the field, and change the shape of the support surface 131 according to the softness of the body part (such as the hardness of the part where the bone is located and the part where the muscle is located) during the movement of the support bracket 13, to avoid hard collision with the wounded part or the pressure sore part. The support assembly connected in the cavity 132 can support the support surface 131 to a certain extent, avoid the situation that the support surface 131 is too low to support a part of the body, and further ensure that each part of the back of the wounded person can be lifted in turn, so that the pressure sore or the wounded part is separated from the surface of the inflatable cushion, so that these parts are not pressed and ventilated, and the generation of pressure sores is prevented.

[0051] Specifically, in the embodiment of the present application, the support assembly comprises a spring 133 and a scissor linkage structure 134. One end of the spring 133 is fixed to the body 130, and the other end is fixed to the support surface 131. The extension direction of the spring 133 is consistent with the height direction of the body 130. The scissor linkage structure 134 is located in the spring 133. One end of the scissor linkage structure 134 is rotatably connected to the body 130, and the other end is rotatably connected to the support surface 131. The extension direction of the scissor linkage structure 134 is consistent with that of the spring 133.

[0052] The scissors linkage structure 134 comprises a plurality of linkage assemblies, and it should be understood that the spring 133 is fixed at both ends with spring seats, the spring seats are respectively fixed on the support surface 131 and the bottom of the body 130, the spring 133 is supported through the spring seats, a plurality of sequentially pivoted linkages are connected in the spring, the plurality of linkages are relatively resolved, and the scissors linkage structure is formed. The topmost and lowest linkages are connected with the corresponding spring seats. The spring 133 can play a role in supporting the support surface 131 elastically, and further adapt to the shape of each position of the body when the body moves relative to the air cushion 10 during the transfer process in the field, and change the rigid support to flexible support, so that the wounded person is more comfortable. In addition, the support 13 can change the shape of the support surface 131 during the movement process according to the softness of the body part (such as the hardness of the part where the bone is located and the part where the muscle is located), so as to avoid hard collision with the body of the wounded person. The support assembly connected in the cavity 132 can play a certain supporting role on the support surface 131, so as to avoid the situation that the support surface 131 is too low to support the body part, and further ensure that the wounded person can be lifted up sequentially. In this way, the neck and the neck part can be separated from the surface of the air cushion, so that these parts are not pressed and ventilated, preventing the occurrence of pressure sores. The scissors linkage structure 134 can play a guiding role on the spring 133, so as to avoid the spring 133 from being skewed during the extension and retraction process and thus losing the support on the support surface 131. In addition, the scissors linkage structure 134 can play a certain rigid supporting role, further avoiding the crushing of the spring 133, and ensuring the moderate elastic support.

[0053] Again referring to Figure 2 , the bottom support air cushion 14 is connected between the air cushion 10 and the stretcher 2. The bottom support air cushion 14 has a gas charging and discharging port. The top surface shape of the bottom support air cushion 14 matches the bottom surface shape of the air cushion 10. Considering that the stretcher often cannot be completely straightened during the transfer process, it is generally recessed towards the middle position. When the air cushion 10 is deflated during the nursing of the wounded person, it also presents a collapsed state, and the supportability is poor, which may not be able to support the top surface of the support 13 on the surface of the air cushion, so as to support the wounded person pressure sores or wound parts. Therefore, the bottom support air cushion 14 is connected between the air cushion 10 and the stretcher 2. The bottom support air cushion 14 can be provided with a bandage or a magic tape around the circumference. The bandage or the magic tape can be wound on the fixed rod 20 to realize the fixation of the two. The bottom of the air cushion 10 and the top surface of the bottom support air cushion 14 are completely attached through the magic tape. After the bottom support air cushion 14 is fully inflated, the air can form a support on the bottom of the air cushion 10, so as to further support the support 13, so as to ensure that it can support the wounded person, so that the pressure sores or wound parts are separated from the surface of the air cushion 10, and the nursing effect is achieved.

[0054] Considering that the support 13 can be moved at any position at any time as much as possible, again referring to Figure 4 ,Figure 5 、 Figure 6 and Figure 9 wherein, Figure 9 is Figure 5 The local structure amplification diagram at H in the air field medical lying position pressure sore nursing equipment in the embodiment of the application further comprises a transverse moving assembly 12 connected at the inner side wall in the width direction of the inflatable pad 10, each transverse moving assembly 12 comprises a support frame 120, a lead screw 121 and a nut seat 122, the support frame 120 is in a U shape, the support frame 120 is fixed at the bottom of the side wall in the width direction of the inflatable pad 10, the lead screw 121 is arranged in the width direction of the inflatable pad 10, one end of the lead screw 121 is rotationally connected with the side wall of the support frame 120, the other end of the lead screw 121 extends out of the inflatable pad 10 through the side wall of the support frame 120 and the inflatable pad 10, the nut seat 122 is screwed with the lead screw 121, the bottom of the nut seat 122 is slidingly matched with the bottom of the support frame 120 in the width direction of the inflatable pad 10, and the fixed pulley 110 is connected to the nut seat 122 in one-to-one correspondence.

[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 when used in the field, the part of the lead screw 121 extending out of the inflatable pad 10 is fixed with a rotating handle 123, the rotation of the lead screw 121 is realized by rotating the rotating handle 123 during use, and the fixed pulley 110 can be moved, so that the support bracket 13 can move in the transverse direction, it should be noted that the connection part of the self-locking bearing 124 and the inflatable pad 10 needs to be sealingly connected, such as sealingly connected through a sealing ring, the bottom of the support frame 120 plays a guiding role, a sliding groove is formed in the width direction of the inflatable pad 10 at the bottom of the support frame 120, and the bottom of the nut seat 122 is slidingly matched with the sliding groove, so that the fixed pulley 110 can move in the longitudinal direction while moving in the transverse direction with the nut seat 122.

[0056] When folding, the inflatable pad 10 and the bottom support air pad 14 are both deflated, and the two are folded in the width direction of the inflatable pad 10.

[0057] In the embodiment of the application, with specific reference to Figure 9The driving member 112 comprises a telescopic rod arranged along the width direction of the air cushion 10, one end of the telescopic rod is fixedly connected with the center of the fixed pulley 110, and the other end of the telescopic rod extends out of the side wall of the air cushion 10 through the side wall of the support frame 120. The telescopic rod is arranged as a telescopic rod so as to be telescopic with the fixed pulley 110 when the fixed pulley 110 moves laterally with the nut seat 122. Considering the field use, the telescopic rod is connected with the side wall of the support frame 120 through a self-locking bearing, the telescopic rod is sealingly connected with the side wall of the air cushion 10, and the part of the telescopic rod extending out of the air cushion 10 is fixed with a hand wheel 113. In use, the longitudinal movement is realized by rotating the hand wheel 113. In addition, it should be noted that the fixed pulley 110 is rotationally connected with a fixed frame 114, and the fixed frame 114 is fixed with the nut seat.

[0058] In the embodiment of the present application, the flexible surface of the air cushion 10 away from the stretcher 2 is flexible, and the part of the air cushion 10 supported by the support 13 and other areas will not be in an excessively tight state when the air cushion 10 is in a concave state, that is, the part of the air cushion 10 not in contact with the body is relatively collapsed, the contact area of the body and the air cushion 10 is reduced to the greatest extent, the pressure on the non-contact part of the body is released, and the generation of pressure sores is further avoided. For example, the material of the air cushion 10 is relatively soft, and a breathable mesh can be added to the upper surface of the air cushion 10, so that the body of the wounded person directly contacts the breathable mesh when supporting a part of the body, and the breathability is increased.

[0059] Considering the comprehensive consideration of the support height and comfort, the height difference between the highest part and the lowest part of the air cushion 10 is 3cm-5cm when the air cushion 10 is in an unfull air state. If the support height is less than 3cm, the distance between the part of the body not in contact with the air cushion 10 and the air cushion 10 is small, the breathability is not good, and pressure sores are easily generated. If the support height is greater than 5cm, the distance between the part of the body not in contact with the air cushion 10 and the air cushion 10 is large, the extrusion effect of the contact part is obvious, and blood stasis is easily generated.

[0060] The above-mentioned embodiments are only some specific embodiments of the present application, but the embodiments of the present application are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present application.
