[0045] The following combination Figures 1-21 , some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] In the first aspect, the present invention provides a full-position mattress, such as Figure 1 and Figure 2 As shown, it includes a first mattress 1, a second mattress 2 and a third mattress 3; the second mattress 1 is arranged at one end of the first mattress 1; the first mattress 1 and the second mattress 2 have the same width, and the thickness of the second mattress 2 is less than the thickness of the first mattress 1, so that a step groove is formed between the first mattress 1 and the second mattress 2; the third mattress is arranged above the second mattress, and the upper surface of the third mattress is flush with the upper surface of the first mattress.

[0047] In this embodiment, the first mattress 1 is used as the main body of the mattress, and the second mattress 2 is located below the patient's head. When used in a prone position, the patient's face faces the second mattress 2. Since the thickness of the second mattress 2 is less than that of the first mattress 1, the second mattress 2 will not contact the patient's face, thereby preventing the patient from suffocating. At the same time, it is convenient for medical facilities such as airway tubes to pass through the top of the second mattress 2 to contact the patient's head and provide treatment to the patient.

[0048] In this embodiment, the third mattress 3 is stacked with the second mattress 2 , and the sum of the thicknesses of the second mattress 2 and the third mattress 3 is the same as the thickness of the first mattress 1 .

[0049] This arrangement allows the full-position mattress to be used as both a prone position mattress and a supine position mattress.

[0050] When used as a prone position mattress, the third mattress 3 is not used. When used as a supine position mattress, the third mattress 3 is placed on the second mattress 2.

[0051] In a preferred embodiment, the first mattress 1 and the second mattress 2 are integrally provided.

[0052] Specifically, in this embodiment, the first mattress 1 and the second mattress 2 are provided as an integrated unit, which can ensure the stability of the relative position of the first mattress 1 and the second mattress 2 and facilitate direct use after moving without the need for separate assembly.

[0053] It is understandable that the first mattress 1 and the second mattress 2 can be an integral structure or they can be separate structures, as long as the thickness of the first mattress 1 is greater than the thickness of the second mattress 2 .

[0054] In a preferred embodiment, Figure 3As shown, a support portion 8 is provided at one end of the first mattress 1 close to the second mattress 2 , and the support portion 8 is used to maintain the support state of the first mattress 1 at this position.

[0055] In this embodiment, the support portion 8 is provided so that when the first mattress 1 is inflated or deflated, the end of the first mattress 1 close to the second mattress 2 will not be affected, and the end portion can be prevented from being easily deformed and causing discomfort to the patient.

[0056] Specifically, in this embodiment, the material of the support portion 8 can be sponge, or other flexible materials with a certain supporting strength, which can ensure the supporting effect while avoiding the comfort affected by too high hardness.

[0057] In this embodiment, the first mattress 1 and the second mattress 2 are both air mattresses, and when the first mattress 1 and the second mattress 2 are integrally arranged, the communication pipe between the first mattress 1 and the second mattress 2 can be arranged through the support portion 8.

[0058] In a preferred embodiment, Figures 12-18 As shown, the third mattress 3 includes a left movable unit and a right movable unit; the length of the left movable unit is smaller than that of the right movable unit; and the joint between the left movable unit and the right movable unit is perpendicular to the length direction of the head ventilation groove.

[0059] In this embodiment, the third mattress 3 is divided into two parts along the length direction of the bed, namely a left movable unit and a right movable unit, that is, the left end part of the third mattress 3 can be moved and removed, or the right end part of the third mattress 3 can be moved and removed.

[0060] This setting allows the patient to lie in a prone position with the head in a side-facing position, with the left or right movable unit providing a certain degree of support, thereby reducing pressure on the forehead and increasing comfort during use.

[0061] Specifically, in this embodiment, the third mattress 3 is arranged symmetrically, that is, the left movable unit can also be arranged on the right side, and the right movable unit can also be arranged on the left side. When in use, the patient can use the left side of the face to support or the right side of the face to support.

[0062] It can be understood that, in this embodiment, the third mattress 3 is divided into two parts, but it is not limited to two parts, and it can also be divided into three or more parts for assembly.

[0063] In a preferred embodiment, the full-recumbent mattress further includes an outer cover 9 ; the first mattress 1 , the second mattress 2 , and the third mattress 3 are all disposed within the outer cover 9 .

[0064] In this embodiment, the outer cover 9 covers the first mattress 1, the second mattress 2, the third mattress 3 and even the fourth mattress 4. After the patient has finished using the mattress, the outer cover 9 is removed and only the outer cover 9 needs to be cleaned, which is convenient for cleaning the full-recumbent mattress and avoids cross infection that may occur when different patients use the mattress.

[0065] Specifically, in this embodiment, the outer cover 9 is configured to be bag-shaped, and an opening is formed on the upper surface or the lower surface thereof via a zipper, so that the full-recumbent mattress can be conveniently placed into the outer cover 9 .

[0066] It is understandable that the outer cover 9 can be arranged in the bag-like structure mentioned above, or it can be other structures, such as a cover structure that only covers the upper surface and four side surfaces of the full-recumbent mattress.

[0067] In a preferred embodiment, the third mattress 3 is made of sponge or airbag.

[0068] It is understandable that, in this embodiment, the material of the third mattress 3 may be sponge, but it is not limited to sponge, and it may also be other materials.

[0069] In a preferred embodiment, the full-recumbent mattress further comprises a fourth mattress 4; Figures 3 to 20 As shown, the fourth mattress is arranged at the end of the second mattress 2 away from the first mattress 1, and the thickness of the fourth mattress 4 is the same as or less than the thickness of the first mattress 1, and greater than the thickness of the second mattress 2, so that the stepped groove can be formed into a head ventilation groove with a rectangular cross-section.

[0070] Specifically, in this embodiment, when the thickness of the fourth mattress 4 is less than that of the first mattress 1 and greater than that of the second mattress 2 , it saves material and facilitates the placement and removal of the third mattress 3 .

[0071] In this embodiment, the first mattress 1, the second mattress 2 and the fourth mattress 4 can be set as an integrated arrangement. At this time, a head ventilation groove is formed above the second mattress 2 between the first mattress 1 and the fourth mattress 4, and the third mattress 3 is placed in the head ventilation groove. The connection method between the third mattress 3 and the head ventilation groove can be a clearance fit, a transition fit or an interference fit.

[0072] When used as a prone position mattress, the third mattress 3 is removed from between the first mattress 1 and the fourth mattress 4, so that a head ventilation groove is formed between the first mattress 1 and the fourth mattress 4. At this time, the patient's head faces downward, with the forehead placed on the fourth mattress 4, and the chin can be placed on the first mattress 1, or suspended in the air, so that the mouth and nose are in the head ventilation groove, which facilitates the connection of the ventilation tube to the patient's mouth and nose.

[0073] In this embodiment, when the fourth mattress 4 is separated from the second mattress 2, due to individual differences among patients, after the third mattress 3 is removed, the width of the head ventilation groove can be adjusted by moving the position of the fourth mattress 4 so that it can be suitable for different patients.

[0074] That is to say, the full-lying position mattress provided by the utility model can be used as a prone position mattress and can also be used as a normal position mattress, achieving a multifunctional effect.

[0075] In a preferred embodiment, the fourth mattress 4 is provided with a head placement groove, such as Figure 19 and Figure 20 shown.

[0076] When the patient is in the prone position, after removing the third mattress 3, the patient's forehead is placed in the head placement groove 7, which can not only locate the patient's position to prevent the patient from shaking and affecting the stability of the tracheal connection, but also increase the patient's comfort during use.

[0077] In this embodiment, the head placement groove 7 is an arc-shaped groove.

[0078] It should be pointed out that the head placement groove 7 can be set as an arc groove, but it is not limited to the arc groove. It can also be other structures, such as a rectangular groove, a trapezoidal groove, etc., as long as it can achieve the placement and positioning of the patient's head.

[0079] In this embodiment, in order to prevent the full-recumbent mattress from sliding during use, an anti-slip pad 6 can be provided under the first mattress 1, the second mattress 2 and the fourth mattress 4. Figure 8 、 Figure 9 and Figure 10 shown.

[0080] Specifically, in this embodiment, the anti-slip pad 6 can be connected to the first mattress 1, the second mattress 2 and the fourth mattress 4 by means of Velcro or the like, further ensuring that the first mattress 1, the second mattress 2 and the fourth mattress 4 will not slide during use, thereby improving the patient's comfort during use.

[0081] In a preferred embodiment, a positioning groove / positioning protrusion 4 is provided on the side wall of the head ventilation groove, and a positioning protrusion 4 / positioning groove is provided on the third mattress 3, and the positioning protrusion 4 is provided in coordination with the positioning groove.

[0082] In this embodiment, to prevent the third mattress 3 from sliding within the head ventilation groove when used as a normal mattress, positioning protrusions 4 are provided on opposite sides of the third mattress 3, and positioning grooves corresponding to the positioning protrusions 4 are provided at the ends of the first mattress 1 and the fourth mattress 4. After the positioning protrusions 4 are set in the positioning grooves, the third mattress 3 can be prevented from moving in the left and right directions.

[0083] Specifically, in this embodiment, the positioning groove matches the shape of the positioning protrusion 4 .

[0084] More specifically, in this embodiment, the shape of the positioning groove can be a rectangular groove, a semicircular groove, an arcuate groove, or a trapezoidal groove, etc., as long as it can match the shape of the positioning protrusion 4.

[0085] In a preferred embodiment, the positioning groove is provided on a side wall at a middle portion or an end portion of the head ventilation groove.

[0086] In this embodiment, the positioning groove can be set in the middle of the head ventilation groove or at both ends, as long as the positioning groove and the positioning protrusion 4 can be matched to achieve the positioning of the third mattress 3 in the head ventilation groove.

[0087] It can be understood that in this embodiment, positioning grooves are provided on both the first mattress 1 and the fourth mattress 4, but positioning grooves may be provided only on the first mattress 1 or the fourth mattress 4. In this case, only one positioning protrusion 4 needs to be provided on the third mattress 3.

[0088] It can also be understood that the number of positioning grooves can be one or more, and they can be set on the first mattress 1 and the fourth mattress 4 respectively, or they can be set on the first mattress 1 or the fourth mattress 4, and the shapes of the multiple positioning grooves can also be the same or not completely the same, as long as the positioning grooves and the positioning protrusions 4 can cooperate to achieve the positioning of the third mattress 3.

[0089] It can also be understood that, in this embodiment, the positioning protrusion 4 is provided on the third mattress 3 , which may be achieved by providing the positioning protrusion 4 on the first mattress 1 and / or the fourth mattress 4 , and providing a matching positioning groove on the third mattress 3 .

[0090] In this embodiment, when the third mattress 3 is positioned in the head ventilation groove, the positioning protrusion 4 can be set on the side wall that matches the first mattress 1 and the fourth mattress 4, such as Figure 4 and Figure 5 As shown, it can also be set at the bottom, such as Figure 6 and Figure 7 shown.

[0091] In a preferred embodiment, a foot groove 10 is formed on the upper surface of the first mattress 1 at one end away from the second mattress 2 .

[0092] In this embodiment, a foot groove 10 is provided on the first mattress 1, which can place the toes of the patient when the patient is in a prone position, thereby avoiding the toes being supported for a long time and improving the comfort of the patient.

[0093] In this embodiment, the foot groove 10 can be set as a through groove, that is, it passes through the width direction of the first mattress 1, or it can be set as a groove that is not through the width direction, as long as it can facilitate the placement of the feet.

[0094] In a preferred embodiment, a perineal groove 11 is provided on the upper surface of the middle portion of the first mattress 1 .

[0095] In this embodiment, after the perineal groove 11 is provided on the upper surface of the middle portion of the first mattress 1, compression of the genitals can be avoided when the male patient is in a prone position, thereby protecting the health of the genitals and improving the comfort of the male patient during use.

[0096] In a preferred embodiment, the first mattress 1 is a micro-permeable mattress; or, the first mattress 1 and the second mattress 2 are both micro-permeable mattresses; or, the first mattress 1, the second mattress 2 and the fourth mattress 4 are all micro-permeable mattresses.

[0097] In this embodiment, the first mattress 1 is a slightly air-permeable mattress, which can effectively prevent the patient from developing bedsores when lying on his back or prone position for a long time, thereby improving the patient's comfort when using the mattress.

[0098] At the same time, the fourth mattress 4 can also be set as a slightly breathable mattress, so that when used in a prone position, it will be more comfortable to place the forehead on the fourth mattress 4, avoiding the occurrence of sweating and stickiness on the forehead due to long-term use.

[0099] In a preferred embodiment, the first mattress 1 includes a plurality of air cushion units; the plurality of air cushion units are spliced ​​together; and the air cushion units are provided with a plurality of micro air holes.

[0100] In this embodiment, the first mattress 1 is composed of multiple air cushion units, and each air cushion unit is provided with multiple micro air holes on the upper surface. When in use, the micro air holes always blow air to the outside, thereby reducing the direct contact area between the patient's skin and the air cushion unit, which not only increases comfort but also avoids bedsores caused by long-term large-area airtightness.

[0101] In this embodiment, each air cushion unit is connected to a ventilation pump, and each ventilation pump is connected to a flow control valve; or all air cushion units are connected to the same ventilation pump, and a flow control valve is provided at the air inlet of each air cushion unit.

[0102] By setting the flow control valve, the air cushion units at different positions can control different air intakes according to different pressures, so that the air intake of the air cushion units and the exhaust of the micro-air holes reach a balance, ensuring the normal use of the first mattress 1.

[0103] In a preferred embodiment, a ventilation tube is connected to the air cushion unit; one end of the ventilation tube is connected to the air pump, and the other end of the ventilation tube is connected to the air cushion unit for inputting gas into the air cushion unit.

[0104] Alternatively, in this embodiment, one end of the ventilation tube is connected to the air pump, and the other end of the ventilation tube is arranged above the air cushion unit. The ventilation tube has a plurality of air holes for blowing air to the upper surface of the air cushion unit.

[0105] The ventilation tube is arranged above the air cushion unit, so that the ventilation pump on the ventilation tube is different from the ventilation pump connected to the air cushion unit, so that the air source of the air cushion unit is different from the air source of the ventilation tube, avoiding the dry and hot air in the air cushion unit blowing on the patient's back, which is easy to cause dehydration, and improving the patient's comfort.

[0106] In a second aspect, the present invention further provides a full-recumbent treatment bed, which includes any of the full-recumbent mattresses described above.

[0107] The beneficial effects of the embodiments of the present utility model are:
