Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to pillows. Background Technology

[0002] After each surgery, medical staff need to thoroughly disinfect the headrests used by patients to avoid cross-infection. However, since multiple surgeries may be scheduled in one operating room on the same day, when there are many surgeries, a large number of headrests need to be disinfected by spraying disinfectant. At the same time, every part of the headrests needs to be thoroughly disinfected and aired out, which prolongs the working time required for medical staff to disinfect the headrests and increases their workload. Utility Model Content

[0003] In view of this, the present invention provides a pillow to solve the problem that after surgery, medical staff need to disinfect the headrest, which increases the workload of medical staff when there are many surgeries.

[0004] This utility model provides a pillow, comprising:

[0005] A pillowcase with a receiving cavity and an opening, one side of which communicates with the outside and the other side of which communicates with the receiving cavity, the pillowcase comprising at least two breathable layers;

[0006] The pillow core is a breathable pillow core, and the pillow core has a first state in which it is disposed within the receiving cavity, and a second state in which it is disposed outside the receiving cavity.

[0007] Beneficial Effects: By specifying that the pillow core is a breathable pillow core and the pillowcase includes at least two breathable layers, the pillow formed by connecting the pillow core and pillowcase meets the requirements for pillows in operating rooms. Simultaneously, by providing a detachable connection between the pillowcase and pillow core, the pillow core can be in a first state where it is located within the pillowcase's receiving cavity (i.e., the pillow is in use), and in a second state where it is located outside the receiving cavity (i.e., the pillow is ready to be removed and replaced with a new pillowcase). Replacing the pillowcase with a new one not only achieves the same effect of preventing cross-infection but also eliminates the need for the meticulous disinfection of every part of the pillow surface required in related technologies. This saves medical staff the time needed to disinfect pillows during use, thereby reducing their workload.

[0008] Meanwhile, in this embodiment, the pillows do not need to be disinfected and aired with disinfectant, which shortens the disinfection time and avoids the situation where there are not enough pillows to affect their use.

[0009] In one optional embodiment, the breathable layer is a non-woven fabric layer;

[0010] And / or, the breathable pillow core is a gel pillow core;

[0011] And / or, the pillow cores located on both sides of the opening are detachably connected so that the opening has an open third state and a closed fourth state;

[0012] And / or, the pillow core is U-shaped.

[0013] Beneficial effects: By limiting the breathable layer to a non-woven fabric layer, non-woven fabric is low in cost and readily available, thereby achieving the technical effect of reducing the manufacturing cost of pillows;

[0014] By limiting the breathable pillow core to a gel pillow core, that is, the breathable pillow core is made of gel material. This pillow core can deform with the pressure applied by the patient's head. When the pressure of the patient's head is removed, the gel pillow core returns to its original position, thereby achieving the technical effect of improving the patient's comfort.

[0015] By detachably connecting the pillow cores located on both sides of the opening, the state of the opening can be adjusted as needed. When the pillow core is in the first state, the opening is in the fourth state, allowing the pillowcase to completely seal the pillow core within the cavity, preventing exposure and potential contamination or cross-infection, thus improving the hygiene of the pillow. Simultaneously, when the pillow core is being adjusted from the first state to the second state, the opening is in the third state, allowing the pillow core to be placed outside the pillowcase for easy replacement.

[0016] By defining the pillow core as a "U" shape, i.e., a headrest, it can be used in the prone position of patients during surgery, avoiding the stuffy and uncomfortable feeling caused by ordinary shaped pillows, such as square pillows, thereby achieving the technical effect of improving the comfort of patients in the prone position.

[0017] In one alternative embodiment, the pillow comprises:

[0018] A fixing unit is detachably connected to the pillow cores on both sides of the opening, so that the opening has a third state and a fourth state.

[0019] Beneficial effects: By setting a fixed unit that can be detachably connected to the pillow cores on both sides of the opening, the third and fourth states of the opening can be adjusted and switched.

[0020] In one optional implementation, the fixing unit includes:

[0021] The first fixing structure is connected on one side to the pillow core on the side of the opening;

[0022] The second fixing structure is connected on one side to the pillow core on the other side of the opening, and the other side of the second fixing structure is detachably connected to the other side of the first fixing structure.

[0023] In one optional embodiment, the first fixing structure is a first zipper, the second fixing structure is a second zipper, and the first zipper and the second zipper are detachably connected.

[0024] Alternatively, one of the first fixing structure and the second fixing structure may be a hook-and-loop fastener and the other may be a loop-and-loop fastener.

[0025] In one alternative embodiment, the pillowcase includes:

[0026] An antibacterial layer is disposed on one side of the breathable layer and connected to the breathable layer.

[0027] Beneficial effects: By setting an antibacterial layer, the types of bacteria that can be isolated can be further increased, thereby achieving the technical effect of improving the hygiene of the pillow.

[0028] In one alternative embodiment, the antibacterial layer is a bamboo fiber layer or a cotton or linen layer.

[0029] In one alternative embodiment, the pillow comprises:

[0030] An extension unit is connected to the pillowcase, the extension unit is arranged along the length direction of the pillowcase, and is used to adjust the thickness of the pillowcase, and / or, the extension unit is arranged along the thickness direction of the pillowcase, and is used to adjust the length of the pillowcase.

[0031] Beneficial effects: By setting up extension units, the thickness and length of the pillowcase can be adjusted, eliminating the need to make multiple sizes of pillowcases to fit different sizes of pillow cores, thereby improving the applicability of the pillowcase and achieving the technical effect of saving pillow manufacturing costs.

[0032] In one alternative implementation, the extension unit includes:

[0033] The first extension structure is connected to the pillowcase on one side;

[0034] The second extension structure has one side spaced apart from the other side of the first extension structure, and one side of the second extension structure is detachably connected to the other side of the first extension structure, while the other side of the second extension structure is connected to the pillowcase.

[0035] In one alternative embodiment, the first extension structure and / or the second extension structure are disposed on the outer side of the pillowcase.

[0036] Beneficial effects: By limiting the first and second extension structures to the outer side of the pillowcase, it is possible to prevent the first and second extension structures from coming into contact with the patient and causing discomfort. This utility model, by limiting the first and second extension structures to the outer side of the pillowcase, can achieve the technical effect of improving the patient's comfort.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The following is combined with Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, a pillow is provided, comprising:

[0046] Pillowcase 1 has a receiving cavity and an opening. One side of the opening communicates with the outside and the other side communicates with the receiving cavity. Pillowcase 1 includes at least two breathable layers.

[0047] Pillow core 2 is a breathable pillow core. Pillow core 2 has a first state in which it is disposed within the receiving cavity and a second state in which it is disposed outside the receiving cavity.

[0048] In this embodiment, the pillow is used in a hospital operating room.

[0049] In this embodiment, the pillow core 2 is defined as a breathable pillow core, and the pillowcase 1 includes at least two breathable layers. This ensures that the pillow formed by connecting the pillow core 2 and the pillowcase 1 meets the requirements for pillows in the operating room, namely, breathability and hygiene. Furthermore, by providing a detachable connection between the pillowcase 1 and the pillow core 2, the pillow core 2 can be in a first state where it is located within the receiving cavity of the pillowcase 1, indicating that the pillow is in use. It can also be in a second state where the pillow core 2 is located outside the receiving cavity of the pillowcase 1, indicating that the pillow is ready to be removed and replaced with a new pillowcase 1. Replacing the pillowcase 1 with a new one not only achieves the same effect of preventing cross-infection but also eliminates the need for the meticulous disinfection of every part of the pillow surface required in related technologies. This saves medical staff time spent disinfecting pillows during use, thereby reducing their workload.

[0050] Meanwhile, in this embodiment, the pillows do not need to be disinfected and aired with disinfectant, which shortens the disinfection time and avoids the situation where there is not enough pillows to affect their use.

[0051] Of course, in other embodiments, the pillow can be used in other scenarios, such as hospital wards.

[0052] Furthermore, in this embodiment, the pillowcase 1 includes two breathable layers. Based on this, while ensuring the pillow's breathability, the two breathable layers can also block bacteria, preventing harmful substances such as bacteria from the patient's body from entering the pillow core 2, thereby achieving the technical effect of improving the safety of pillow use.

[0053] Furthermore, in this embodiment, the breathable layer is a non-woven fabric layer. Non-woven fabric is low in cost and readily available, thereby achieving the technical effect of reducing the manufacturing cost of the pillow.

[0054] Of course, in other embodiments, the material of the breathable layer may be adjusted depending on the design of the pillow.

[0055] In other embodiments, the number of layers of pillowcase 1 may be adjusted according to the design of the pillow. For example, pillowcase 1 may have one or more layers, all of which are within the protection scope of this utility model.

[0056] In addition, combined Figure 1As shown, in this embodiment, the pillow core 2 is U-shaped, that is, the pillow core 2 is a head pillow, which can be used for the patient's prone position during surgery, avoiding the stuffy discomfort caused by ordinary shaped pillows, such as square pillows, to the patient in the prone position, thereby achieving the technical effect of improving the patient's comfort in the prone position.

[0057] Among them, pillow core 2 is a breathable pillow core, and the breathable pillow core is a gel pillow core, that is, the breathable pillow core is made of gel material. The pillow core 2 can deform with the pressure applied by the patient's head. When the pressure of the patient's head is removed, the gel pillow core returns to its original position, thereby achieving the technical effect of improving the patient's comfort.

[0058] Of course, in other embodiments, the shape of the pillow core 2 can be adjusted according to the different designs of the pillow, and various shapes of pillow core 2 can be designed to suit the various lying positions of the patient during the operation.

[0059] In other embodiments, the material of the breathable pillow core is adjusted according to the different pillow designs. Alternatively, the pillow core 2 may not be breathable, all of which are within the protection scope of this utility model.

[0060] In addition, in this embodiment, the breathable pillow cores located on both sides of the opening are detachably connected so that the opening has a third open state and a fourth closed state.

[0061] The breathable pillow core on both sides of the opening refers to the two edges of the breathable pillow core that form the opening. Based on this, the state of the opening can be adjusted as needed. When the pillow core 2 is in the first state, the opening is in the fourth state, allowing the pillowcase 1 to completely seal the pillow core 2 within the cavity, preventing the pillow core 2 from being exposed and causing contamination and cross-infection, thus improving the hygiene of the pillow. Simultaneously, when the pillow core 2 is being adjusted from the first state to the second state, the opening is in the third state, allowing the pillow core 2 to be placed outside the pillowcase 1 through the opening for easy replacement of the pillowcase 1.

[0062] Specifically, in this embodiment, the opening is located on the outer side of the pillowcase 1 and follows the outer contour of the pillow core 2, i.e., the opening is a hollow "U" shape. Of course, in other embodiments, the shape of the opening may be adjusted depending on the design of the pillow.

[0063] Alternatively, the breathable pillow cores located on both sides of the opening can be fixedly connected.

[0064] Of course, in other embodiments, depending on the design of the pillow, the breathable layer can be defined as a non-woven fabric layer, the breathable pillow core as a gel pillow core, and the pillow core 2 located on both sides of the opening can be detachably connected, so that the opening has one or more structures or combinations of structures in an open third state and a closed fourth state, all of which are within the protection scope of this utility model.

[0065] In this embodiment, there is one opening. Of course, in other embodiments, the number of openings may be adjusted depending on the pillow design.

[0066] In addition, combined Figure 1 As shown, in this embodiment, the needle includes:

[0067] The fixing unit 3 is detachably connected to the breathable pillow cores on both sides of the opening so that the opening has a third state of being open and a fourth state of being closed.

[0068] By setting the fixing unit 3 to be detachably connected to the breathable pillow cores on both sides of the opening, the third and fourth states of the opening can be adjusted and switched.

[0069] The fixed unit 3 includes:

[0070] The first fixing structure 301 is connected to the pillow core 2 on the open side on one side;

[0071] The second fixing structure 302 is connected on one side to the pillow core 2 on the other side of the opening, and the other side of the second fixing structure 302 is detachably connected to the other side of the first fixing structure 301.

[0072] Specifically, one side of the first fixing structure 301 is sewn and fixed to the pillow core 2 on the side of the opening, and the second fixing structure 302 is sewn and fixed to the pillow core 2 on the other side of the opening, thereby achieving the technical effect of improving the stability of the connection between the first fixing structure 301 and the pillow core 2 and between the second fixing structure 302 and the pillow core 2.

[0073] Preferably, one side of the first fixing structure 301 is a first zipper, and the second fixing structure 302 is a second zipper. The first fixing structure 301 and the second fixing structure 302 are locked together by the engagement of the teeth of the first zipper and the teeth of the second zipper, thus placing the opening in the fourth state. The first fixing structure 301 and the second fixing structure 302 are disassembled by the separation of the teeth of the first zipper and the teeth of the second zipper, thus placing the opening in the third state.

[0074] Furthermore, the fixing unit 3 includes:

[0075] The third fixing structure 303 is slidably connected to both the first fixing structure 301 and the second fixing structure 302. By sliding along the length of the first fixing structure 301 and the second fixing structure 302, the first fixing structure 301 and the second fixing structure 302 can switch between a locked and a disassembled state. In other words, the third fixing structure 303 is a pull head.

[0076] Of course, in other embodiments, depending on the pillow design, the third fixing structure 303 may not be provided, and the teeth of the first fixing structure 301 may be manually engaged and disengaged from the teeth of the second fixing structure 302 one by one. Compared to other embodiments, in this embodiment, the user can adjust the locking and fixing state and the disassembly state between the first fixing structure 301 and the second fixing structure 302 by driving the third fixing structure 303 to slide along the length direction of the first fixing structure 301 and the second fixing structure 302, thereby improving the ease of adjustment between the fourth and third opening states, and thus improving the ease of use of the pillow.

[0077] In other embodiments, depending on the pillow design, the fixing unit 3 may not be provided. In other embodiments, the fixing unit 3 may be a stitch, with the pillow cores 2 on both sides of the opening sewn together to achieve a detachable connection between the fixing unit 3 and the pillow cores 2 on both sides of the opening. Specifically, the stitches fix the pillow cores 2 on both sides of the opening, at which point the opening is in the fourth state. Removing the stitches returns the opening to the third state. Compared to other embodiments, this embodiment, by defining the fixing unit 3 as including a first fixing structure 301 and a second fixing structure 302, eliminates the need for stitching and removing stitches, thereby achieving the technical effect of improving the ease of adjustment between the third and fourth states of the opening.

[0078] Of course, in other embodiments, depending on the design of the pillow, the connection method between the first fixing structure 301 and the breathable pillow core and between the second fixing structure 302 and the breathable pillow core can be adjusted, for example, by adhesive bonding.

[0079] In other embodiments, the specific structures of the first fixing structure 301 and the second fixing structure 302 are adjusted. For example, one of the first fixing structure 301 and the second fixing structure 302 is a hook and loop fastener and the other is a loop fastener. This can also achieve a detachable connection between the first fixing structure 301 and the second fixing structure 302.

[0080] Furthermore, in this embodiment, there is only one third fixing structure 303. Of course, in other embodiments, the number of third fixing structures 303 can be adjusted according to the different designs of the pillow. For example, two third fixing structures 303 can be used, and the two third fixing structures 303 are set in opposite directions, which can also achieve the adjustment of the third and fourth opening states.

[0081] Furthermore, in this embodiment, the pillow includes:

[0082] An extension unit, connected to pillowcase 1, is arranged along the length of pillowcase 1 and is used to adjust the thickness of pillowcase 1. Here, the length of pillowcase 1 refers to the direction along which pillowcase 1 extends. Figure 1 The extension direction shown is the "U" shaped direction, and the thickness of pillowcase 1 is... Figure 1 The location shown is D.

[0083] In this embodiment, the extension direction of the extension unit is parallel to the extension direction of the opening.

[0084] As an alternative implementation, the extension direction of the extension unit may not be parallel to the extension direction of the opening.

[0085] Of course, in other embodiments, depending on the pillow design, the extension unit can be arranged along the thickness direction of the pillowcase 1, that is, along the length direction of D, to adjust the length of the pillowcase 1. Alternatively, the extension unit includes two units, namely a first extension unit and a second extension unit. The first extension unit is arranged along the thickness direction of the pillowcase 1 to adjust the length of the pillowcase 1, and the second extension unit is arranged along the length direction of the pillowcase 1 to adjust the thickness of the pillowcase 1.

[0086] In other embodiments, depending on the pillow design, the pillow may not include an extension unit. In this case, the pillowcase 1 may be made in multiple sizes to accommodate pillow cores 2 of different sizes. Compared to other embodiments, this embodiment eliminates the need to manufacture multiple sizes of pillowcase 1 to accommodate pillow cores 2 of different sizes, thereby improving the applicability of the pillowcase 1 and achieving the technical effect of saving on pillow manufacturing costs.

[0087] In addition, in this embodiment, the extension unit includes:

[0088] The first extension structure is connected to the pillowcase 1 on one side;

[0089] The second extension structure is spaced apart from the other side of the first extension structure on one side, and the second extension structure is detachably connected to the other side of the first extension structure. The other side of the second extension structure is connected to the pillowcase 1.

[0090] Specifically, when it is necessary to adjust the thickness D of the pillowcase 1, the first extension structure and the second extension structure can be connected so that the pillowcase 1 between the first extension structure and the second extension structure is hidden in the receiving cavity, thereby achieving the technical effect of reducing the thickness D of the pillowcase 1.

[0091] Preferably, in this embodiment, multiple extension units are spaced apart along the thickness direction of the pillowcase 1. Based on this, the number of extension units can be selected according to the thickness of the pillow core 2, so that the pillowcase 1 can adapt to pillow cores 2 of various thicknesses, thereby achieving the technical effect of improving the adaptability of the pillowcase 1 to pillow cores 2 of different thicknesses.

[0092] In this embodiment, the first extension structure is a third zipper, and the second extension structure is a fourth zipper. The teeth of the third zipper engage with the teeth of the fourth zipper to reduce the thickness of the pillowcase 1. The first extension structure and the second extension structure are detached by separating the teeth of the third zipper and the fourth zipper, thereby releasing the reduced thickness of the pillowcase 1.

[0093] Preferably, the extension unit includes:

[0094] The third extension structure is slidably connected to both the first and second extension structures. By sliding along the length of the first and second extension structures, the first and second extension structures can switch between an engaged state and a disengaged state. In other words, the third extension structure is a pull head.

[0095] Of course, in other embodiments, depending on the pillow design, the third extension structure may not be provided, and the teeth of the first extension structure may be manually engaged and disengaged from the teeth of the second extension structure one by one. Compared to other embodiments, in this embodiment, the user can adjust the engagement and disengagement states between the first and second extension structures by driving the third extension structure to slide along the length direction of the first and second extension structures, thereby improving the ease of adjusting the thickness of the pillowcase 1 and thus enhancing the ease of use of the pillow.

[0096] In other embodiments, depending on the design of the pillow, the specific structure of the first extension structure and the second extension structure can be adjusted. For example, one of the first extension structure and the second extension structure may be a hook and loop fastener and the other may be a loop fastener. This can also achieve a detachable connection between the first extension structure and the second extension structure, thereby achieving the technical effect of adjusting the thickness of the pillowcase 1.

[0097] Of course, in other embodiments, along Figure 1 In the length direction of the pillowcase 1 shown, there are multiple extension units spaced apart for adjusting the length of the pillowcase 1. Based on this, the number of extension units connected can be selected according to the length of the pillow core 2, so that the pillowcase 1 can adapt to pillow cores 2 of various lengths, thereby achieving the technical effect of improving the adaptability of the pillowcase 1.

[0098] In addition, in this embodiment, both the first extension structure and the second extension structure are located on the outer side of the pillowcase 1. Based on this, it is possible to avoid the first extension structure and the second extension structure from coming into contact with the patient and hurting the patient. In this embodiment, by limiting the first extension structure and the second extension structure to the outer side of the pillowcase 1, the technical effect of improving the patient's comfort can be achieved.

[0099] Of course, in other embodiments, depending on the design of the pillow, either the first extension structure or the second extension structure is provided on the outer side of the pillowcase 1, and all of these are within the protection scope of this utility model.

[0100] In other embodiments, the positions of the first extension structure and the second extension structure are adjusted according to the different designs of the pillow.

[0101] Furthermore, in this embodiment, the pillowcase 1 includes:

[0102] An antibacterial layer is disposed on one side of the breathable layer and connected to the breathable layer. In this embodiment, the antibacterial layer may be disposed on the side of the breathable layer closer to the pillow core 2, that is, the antibacterial layer is disposed between the breathable layer and the pillow core 2. Based on this, the breathable layer initially isolates bacteria outside the pillow core 2, and the antibacterial layer can further increase the types of bacteria isolated, thereby achieving the technical effect of improving the hygiene of the pillow.

[0103] In this embodiment, the antibacterial layer and the breathable layer are sewn together and fixed at the same location as the fixing unit 3. That is, by simultaneously sewing together the antibacterial layer, the fixing unit 3, and the breathable layer, the antibacterial layer and the breathable layer are fixed together. Based on this, the number of sewing points can be reduced, and the pillow manufacturing steps can be reduced, thereby improving the ease of pillow manufacturing.

[0104] Specifically, in this embodiment, the antibacterial layer is a bamboo fiber layer. Of course, in other embodiments, the type of antibacterial layer may be adjusted depending on the pillow design; for example, the antibacterial layer may be a cotton or linen layer.

[0105] Of course, in other embodiments, depending on the design of the pillow, the connection method between the antibacterial layer and the breathable layer can be adjusted, for example, the antibacterial layer and the breathable layer can be fixed by adhesive.

[0106] In other embodiments, the antibacterial layer, the fixing unit 3, and the breathable layer may not be sewn together simultaneously, or other sewing methods may be used. These can be adjusted according to the different designs of the pillow, and all are within the protection scope of this utility model.

[0107] In other embodiments, the position of the antibacterial layer relative to the breathable layer may be adjusted depending on the design of the pillow. For example, the breathable layer may be located between the antibacterial layer and the pillow core 2. All of these are within the protection scope of this utility model.

[0108] As an alternative implementation, the pillow may not include an antibacterial layer.

[0109] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
