Description

Technical Field

[0001] This utility model relates to the field of home furnishing manufacturing technology, and in particular to a mattress. Background Technology

[0002] Memory foam mattresses, with their slow rebound properties, can distribute pressure by conforming to the contours of the human body, effectively improving pressure distribution during everyday sleep and becoming one of the mainstream mattress categories. Their standard shape is mostly a rectangular structure, meeting the sleep needs of ordinary users. However, in special scenarios, especially for applications requiring strict postural support such as hair transplant surgery, existing memory foam mattresses and specialized operating tables have significant technical shortcomings.

[0003] During hair transplant surgery, patients need to remain conscious after topical anesthesia and undergo a 3-6 hour procedure on the back of the head while lying prone. The core requirement for the support structure in this scenario is to prevent pressure damage to critical areas of the head and torso (such as the face, chest, and abdomen) while ensuring stable exposure of the surgical area (back of the head) to guarantee sufficient operating space during the prolonged prone position. However, existing products cannot meet these requirements. On the one hand, existing ordinary memory foam mattresses lack designs adapted for medical scenarios. Their standard rectangular structure and general pressure distribution logic are only developed for everyday sleeping positions such as supine and side-lying, without considering the characteristics of the long-term prone position required for hair transplant surgery: when lying prone, the face needs to bear continuous pressure, and ordinary memory foam cannot form a pressure-reducing structure that conforms to the facial contours, which can easily lead to poor facial blood circulation; at the same time, the surgical area at the back of the head lacks dedicated space to avoid interference with the surgical procedure, and the mattress can interfere with the operation, failing to meet the precision requirements of medical procedures. On the other hand, the support structure of existing operating tables has obvious performance shortcomings. Currently, the filling material of the operating table used in hair transplant surgery is mostly ordinary rigid sponge, whose elasticity and pressure distribution ability are far lower than that of professional memory foam material. When the patient lies face down, the rigid sponge cannot effectively buffer the local pressure brought by the body weight, especially in the chest, abdomen and other pressure-bearing areas, which can easily produce a strong feeling of pressure. Moreover, the rigid sponge has poor deformation recovery ability. After lying face down for a long time (more than 1 hour), the pressure will continue to intensify, causing the patient to experience discomfort such as chest tightness and back pain. This not only affects the patient's surgical experience, but may even interfere with the surgical process in severe cases, and cannot meet the positional support requirements of long-term surgery of 3-6 hours. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a mattress that solves the problem that existing ordinary memory foam mattresses, due to their lack of adaptive design, cannot meet the needs of pressure distribution, surgical area avoidance, and long-term comfort for patients lying prone for a long time during hair transplant surgery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a mattress, including a mattress body, which is divided into a head support area and a torso support area. The front of the head support area is flush with the front of the torso support area, and the head support area is located in front of the torso support area. The front of the torso support area is made of elastic material and has several grooves. The head support area has a face ventilation hole that runs through it longitudinally.

[0006] Furthermore, the torso support area is divided into a front region and a rear region, the front region being close to the head support area and the rear region being far from the head support area, and the front region being provided with the groove.

[0007] Furthermore, the depth of the groove is less than the thickness of the mattress body.

[0008] Furthermore, the mattress body includes a first support layer and a second support layer, the first support layer is located above the second support layer, and the first support layer and the second support layer are fixedly disposed together, and the upper surface of the first support layer constitutes the front of the torso support area.

[0009] Furthermore, the depth of the trench is less than or equal to the thickness of the first support layer.

[0010] Furthermore, the first support layer is made of memory foam, and the second support layer is made of memory foam or elastic foam.

[0011] Furthermore, the mattress body also includes a third support layer, which is fixedly disposed at the bottom of the second support layer.

[0012] Furthermore, the third support layer is made of memory foam or elastic cotton.

[0013] Furthermore, the walls of the facial ventilation holes are provided with facial contact surfaces.

[0014] Furthermore, the face-fitting surface is arranged at an angle from top to bottom toward the center of the face ventilation holes.

[0015] The beneficial effects of this utility model compared with the prior art are as follows: A mattress includes a mattress body, which is divided into a head support area and a torso support area. The front of the head support area and the torso support area are arranged flush with each other, and the head support area is located in front of the torso support area. The front of the torso support area is made of elastic material and has several grooves. The head support area has a face ventilation hole that runs through it longitudinally. The design of separate head and torso support areas allows for individual adaptation to the different support needs of the head and torso when the patient is lying prone during hair transplant surgery. This avoids the problem of a one-piece structure being unable to adequately support both. Furthermore, several grooves on the front of the torso support area further optimize the cushioning performance of the elastic material. During the patient's prone position, these grooves adapt to slight body movements, dispersing local pressure and preventing discomfort such as lower back pain and chest tightness caused by concentrated pressure. This also improves the fit between the body and the mattress surface, enhancing comfort during prolonged prone positions. In addition, the longitudinally running facial ventilation holes in the head support area create an effective airflow channel between the face and the outside environment when the patient is lying prone, allowing sweat and heat generated by the scalp to escape promptly, preventing discomfort caused by a stuffy environment.

[0027] like Figures 1 to 2 As shown, this utility model provides a mattress, including a mattress body. The mattress body is divided into two functional areas according to the distribution of body parts when a person is lying prone: a head support area 1 and a torso support area 2. The head support area 1 is used to support the head (including the face, jaw, and part of the neck), while the torso support area 2 is used to support the torso from the shoulders to the hips. To ensure balanced body force when lying prone, the front surfaces (i.e., the surfaces in contact with the body) of the head support area 1 and the torso support area 2 are arranged flush, with the head support area 1 located in front of the torso support area 2 to accommodate the body position where the head is in front and the torso is behind when lying prone. The front of the trunk support area 2 is made of elastic material to conform to the curve of the torso when the patient is lying prone, thus cushioning the local pressure from the body weight. Simultaneously, the front of the trunk support area 2 has several grooves 2111. These grooves 2111 can be arranged in a straight, interlaced, circular, or other shapes. Taking the straight, interlaced arrangement as an example, they can be arranged parallel along the length of the mattress (i.e., the length of the human torso) or staggered along the width of the mattress (i.e., the width of the human torso). The cross-sectional shape of the grooves 2111 can be U-shaped, V-shaped, or trapezoidal, etc., to further increase the deformation space of the elastic material and enhance the pressure distribution effect. The head support area 1 has a longitudinally penetrating facial ventilation hole 11. The position of the facial ventilation hole 11 must correspond to the position of the face (such as the mouth and nose area) when the patient is lying prone. The cross-sectional shape of the hole can be designed as an oval or rectangular shape according to the facial contour to ensure that an effective air circulation channel can be formed between the face and the outside world when lying prone, avoiding stuffiness.

[0028] The partitioned design of the head support area 1 and the torso support area 2 can respectively adapt to the different support needs of the head and torso when the patient is lying prone during hair transplant surgery, avoiding the problem that the overall structure cannot take into account the support adaptability of both. At the same time, the grooves 2111 set on the front of the torso support area 2 can further optimize the cushioning performance of the elastic material. During the patient's prone position, the grooves 2111 can adapt to slight body movements, disperse local pressure, and avoid discomfort such as back pain and chest tightness caused by pressure concentration. At the same time, it can improve the fit between the body and the mattress surface and enhance the comfort of long-term prone position. In addition, the vertically penetrating facial ventilation holes 11 of the head support area 1 can form an effective air circulation channel between the face and the outside world when the patient is lying prone, so as to timely expel the sweat and heat generated by the scalp respiration and avoid discomfort caused by a stuffy environment.

[0029] In some embodiments, the torso support area 2 is divided into a front area 211 and a rear area 212. The front area 211 is close to the head support area 1 and corresponds to the shoulder to waist position when the human body is lying down. The rear area 212 is far from the head support area 1 and corresponds to the waist to hip position when the human body is lying down. The front area 211 is provided with a groove 2111; and the groove 2111 is only provided in the front area 211, while the rear area 212 maintains a flat surface. When a person lies prone, the torso from the shoulders to the waist is close to the head and has a relatively high frequency of movement (such as slight adjustments to the head position easily causing shoulder movements). This area also contains organs and tissues such as the chest or a protruding belly, which have a higher demand for pressure cushioning. Therefore, grooves 2111 are only set in the front area 211 to enhance the pressure distribution effect for this high-demand area, so that the user can lie prone for a long time without discomfort. The rear area 212 (from the waist to the buttocks) has relatively stable force distribution, and the flat surface can provide more stable support, avoiding insufficient support due to too many grooves 2111. In some embodiments, the depth of the groove 2111 is less than the thickness of the mattress body to ensure that the groove 2111 only penetrates the front part of the torso support area 2 and does not penetrate the entire mattress body. The reason for this design is that if the depth of the groove 2111 is equal to or greater than the thickness of the mattress body, the groove 2111 will penetrate the mattress body, destroying the overall structural stability of the mattress and potentially causing a support break in the torso support area 2, making it unable to effectively support the body weight; while when the depth of the groove 2111 is less than the thickness of the mattress body, the bottom of the groove 2111 still retains a certain thickness of support structure, which can ensure the deformation space of the elastic material to achieve pressure distribution and maintain the structural strength of the mattress body, avoiding support failure. In some embodiments, the mattress body includes a first support layer 21 and a second support layer 22. The first support layer 21 is located above the second support layer 22. The two are fixed by bonding (e.g., using medical-grade environmentally friendly adhesive) or physical fixing (e.g., edge stitching, snap-fit ​​connection) to ensure that no relative displacement occurs during use. The upper surface of the first support layer 21 forms the front of the torso support area 2, that is, the grooves 2111 are all provided on the first support layer 21. In some embodiments, the depth of the trench 2111 is less than or equal to the thickness of the first support layer 21. Specifically, if the thickness of the first support layer 21 is 6 cm, the depth of the trench 2111 can be designed to be 4-6 cm: when the depth of the trench 2111 is equal to the thickness of the first support layer 21, the trench 2111 only penetrates the first support layer 21 and does not touch the second support layer 22. At this time, the deformation space of the first support layer 21 is the largest, and the pressure dispersion effect is optimal; when the depth of the trench 2111 is less than the thickness of the first support layer 21 (e.g., 4 cm), the bottom of the trench 2111 retains 2 cm of the first support layer 21 material, which can further improve the support around the trench 2111 while ensuring the deformation space. In some embodiments, the first support layer 21 is made of memory foam, which has slow rebound properties and can slowly deform and conform to the contour according to the pressure of the human body. The pressure is evenly distributed, which can effectively reduce local pressure and is very suitable for the needs of the torso support area 2. The second support layer 22 is made of memory foam or elastic foam. When memory foam is used, its density must be higher than that of the first support layer 21 (e.g., the first support layer 21 is 50D and the second support layer 22 is 70D) to ensure basic support. When elastic foam is used, high-elastic polyester elastic foam can be selected, which has a fast deformation recovery speed and can quickly return to its original shape after the patient adjusts his position, avoiding long-term sinking. In some embodiments, the mattress body further includes a third support layer 23, which is fixedly disposed at the bottom of the second support layer 22. The third support layer 23 is fixedly disposed at the bottom of the second support layer 22, and the fixing method can be by adhesive, sewing, or multi-layer buckle connection. By adding the third support layer 23, the overall support performance can be further optimized, so that the mattress can be adapted to operating tables of different thicknesses and meet the structural strength requirements for long-term use. In some embodiments, the third support layer 23 is made of memory foam or elastic foam. When memory foam is used, its density must be higher than that of the second support layer 22 (e.g., the second support layer 22 is 70D and the third support layer 23 is 80D) to ensure sufficient hardness and anti-slip properties. At the same time, the slow rebound characteristics of memory foam can also help buffer the bottom pressure and avoid hard contact between the mattress and the operating table. When elastic foam is used, high-elastic rubber elastic foam can be selected, which has good elastic deformation ability and coefficient of friction. It can not only conform to the surface of the operating table through deformation to improve anti-slip properties, but also quickly return to its original shape when the mattress is moved, making it convenient to use. In some embodiments, the walls of the facial ventilation holes 11 are provided with facial fitting surfaces 111. These facial fitting surfaces 111 refer to surfaces formed on the walls of the ventilation holes through processes such as grinding and shaping, which conform to the contours of the human face (i.e., the cheeks), rather than traditional right-angled hole walls. For example, the cross-section of the facial ventilation holes 11 is designed to be elliptical, with its major axis along the width of the mattress (fitting the width of the face) and its minor axis along the length of the mattress (fitting the height of the face). The upper and lower sides of the hole wall (corresponding to the forehead and chin positions) are designed as concave arc-shaped fitting surfaces, and the left and right sides (corresponding to the cheek positions) are designed as convex arc-shaped fitting surfaces, so that when the patient lies prone, the face can naturally fit against the hole wall, reducing local pressure. In some embodiments, the facial contact surface 111 is arranged at an angle from top to bottom towards the center of the facial ventilation holes 11. Specifically, the walls of the facial ventilation holes 11 gradually slope towards the central axis of the hole from the top (near the upper surface of the mattress) to the bottom (near the lower surface of the mattress), forming a tapered hole wall structure that is wider at the top and narrower at the bottom. When the patient lies prone, the upper part of the face (forehead) contacts the wide-diameter area at the top of the hole wall, and the lower part of the face (chin) contacts the narrow-diameter area at the bottom of the hole wall. The angled hole wall can better conform to the contour curve of the face from the forehead to the chin. This design achieves a high degree of fit with the contour of the human face, minimizes facial pressure points, and further improves the comfort of lying prone for a long time; at the same time, it optimizes the airflow path of the ventilation holes, enhances the breathability, and provides a better support experience for the patient during the surgical procedure while awake. The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
