Description

Technical Field

[0001] The invention belongs to the technical field of medical nursing equipment, and in particular relates to an anti-seepage partition and an anti-seepage middle sheet using the anti-seepage partition. Background Art

[0002] The middle sheet is widely used in clinical medicine. When used, the middle sheet is laid on the bed sheet to reduce the contamination of the patient's urine or other body fluids on the bed sheet and mattress. The middle sheets currently used in clinical practice are mostly blue middle sheets in disposable surgical kits. Some patients who are bedridden for a long time even use plastic sheets. Both of these materials are non-breathable materials. When used by patients, they come into direct contact with the skin, causing many discomforts. Long-term use will cause itching, allergies and other discomfort symptoms on the skin.

[0003] With the development of science and technology, a simple double-layer structure composed of non-woven fabrics and cast films has emerged. However, this structure only protects the sheets from being contaminated and has a relatively simple function. It is also easy to be damaged and cannot bear weight. For some patients with urinary incontinence or when a large amount of liquid may flow uncontrollably, the simple non-woven fabrics and cast films have limited absorption capacity, and the liquid on the middle sheet cannot be discharged. The wet middle sheet contacts the patient and easily causes discomfort to the patient. For this reason, we propose an anti-seepage partition for the middle sheet and an anti-seepage middle sheet.

[0017] The present application also discloses an anti-seepage middle sheet using the anti-seepage partition plate.

[0018] A seepage-proof middle sheet comprises a waterproof membrane fixed to the middle part of a bed body, the upper end of the waterproof membrane is fixedly connected to a non-woven fabric layer, and the left and right sides of the non-woven fabric layer are open, the front and rear ends of the non-woven fabric layer are both provided with rubber inflatable columns, and a plate body is inserted in the non-woven fabric layer, and the plate body is arranged between two rubber inflatable columns.

[0022] Preferably, the waterproof membrane is fixedly connected to the bed body via a magnetic rubber strip, and lower ends of both sides of the waterproof membrane are lower than the lower side of the bed body.

[0023] Preferably, a one-way valve is provided at the center of one end of the rubber inflatable column, and the one-way valve is connected to the inflatable device through a pipeline.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The anti-seepage partition of the present application is provided with a guide groove. When the liquid seeping down the middle sheet is angled, the liquid is drained to both sides of the plate body through the guide groove and collected by the liquid collecting box, thereby avoiding the incomplete absorption of the liquid caused by the insufficient absorption capacity of the middle sheet made of simple non-woven fabric and cast film, thereby improving the comfort of the patient when using it and improving the applicability of the middle sheet;

[0026] (2) The anti-seepage middle sheet with an anti-seepage partition improves the anti-seepage ability of the middle sheet by setting a plate body. According to specific usage conditions, when a large amount of liquid is about to flow uncontrollably, the plate body can be selectively inserted and pulled out, further improving the applicability of the middle sheet. In addition, the rubber inflatable columns on both sides can create a gap between the middle sheets, making it easier to insert the plate body. The operation is simple and the use is convenient.

[0027] (3) The wedge-shaped slope facilitates the scraper to enter between the non-woven fabric layer and the plate body, and avoids the problem of curling the non-woven fabric layer when the scraper slides along the plate body. The other side of the scraper is an arc surface with a smooth transition from the top to the bottom, so that when the scraper scrapes under the human body, it can form a squeeze on the lower side of its wedge-shaped slope, and its arc-shaped top and back can form a larger area of ​​support, thereby reducing the patient's discomfort;

[0028] (4) By setting a cover plate, the cover plate is relatively hard, and when the scraper bar is hanging, the liquid can be pressed out more completely. The pressed out and hanging liquid flows down along the front side of the cover plate to the scraper bar and is directly absorbed by the scraper bar, avoiding the problem that the scraped liquid is absorbed by the non-woven fabric layer above after the scraper bar passes. When there is too much liquid, it is squeezed by the cover plate during the movement of the scraper bar, and the liquid flows into the guide groove again; when the scraper bar passes through and reaches the other side of the plate body, the pull rope on the other side is pulled to make the scraper bar pass through the non-woven fabric layer and the plate body again. In this process, the side of the cover plate facing the scraper bar is The matching curved surface can also avoid rolling up the non-woven fabric layer, and can also squeeze and scrape the non-woven fabric layer again to further squeeze out and scrape off the liquid thereon. Moreover, in this process, since the cover plate is in an arc shape, one side of it is located at the bottom of the scraper strip, and the other side is at the top of the scraper strip. The scraper strip below the top of the cover plate is in an open state. During the pull-back process, since the scraper strip is deformable, the cover plate is pressed down to squeeze out the liquid adsorbed in the scraper strip and flow it into the chute. After such a process, when the scraper strip is pulled between the non-woven fabric layer and the plate body next time, the scraper strip can restore its water absorption performance.

[0029] Moreover, in order to achieve its absorption performance, the absorbent material usually has numerous tiny gaps in its material. When it contacts with the non-woven fabric layer, there is a great friction force. Therefore, in the solution of the present application, the outer wall of the cover plate is smooth and made of a hard material with elasticity, which greatly reduces the friction force between the cover plate and the non-woven fabric layer. While ensuring the good water absorption of the scraper strip, the non-woven fabric layer will not be wrinkled, and the force required to pull the scraper strip is also greatly reduced.

[0030] (5) The formation of the baffle completely covers the upper edge of the scraper strip. With this structure, the friction between the scraper strip and the non-woven fabric layer is completely replaced by the cover plate, which greatly improves the service life of the scraper strip. In particular, since the scraper strip does not need to consider the friction between the scraper strip and the non-woven fabric layer, it can be made of a water-absorbing material with a more porous texture and better water-absorbing performance, further improving the absorption capacity of the liquid on the non-woven fabric layer; the scraper strip can be made of a material with better water absorption;

[0031] (6) In a natural state, the upper edge of the cover plate is tilted upward. In the scheme of the present application, in a natural state, the upper edge of the cover plate is tilted upward, that is, the tangent line of the top of the cover plate is tilted upward. First, the scraping strength of the upper edge of the cover plate on the non-woven fabric layer is greatly improved. Furthermore, in the scheme of the present application, along the width direction of the hospital bed, the cover plate is in a manner where one side is open and the other side is in contact with the plate body. The direction of the open side is defined as the positive direction, and the direction of the side opposite to the positive direction is defined as the reverse direction. When the scraper and the cover plate are dragged in the positive direction, the cover plate squeezes and scrapes the non-woven fabric layer on the one hand, so that the liquid on and inside the non-woven fabric layer is scraped off until the scraper is sucked in by the scraper or directly flows into the guide groove. Furthermore, the cover plate is fixedly connected to the scraper. Since the non-woven fabric layer cover plate is pressed by the patient to form a downward bulge, during the movement process. In the embodiment, there is actually a certain upward pulling force on the upper end of the cover plate, which ensures that during the movement, the upper edge of the cover plate can adhere to the non-woven fabric layer to achieve a good scraping and squeezing effect. Similarly, when pulling in the reverse direction, a better scraping and squeezing effect can be achieved. Moreover, when the scraper and the cover plate are dragged in the forward direction, although the pressure strip is also in a compressed state, the degree of compression is less than that in the reverse pull, that is, when pulling in the forward direction, it is more convenient for the scraper to absorb the liquid, and when pulling in the reverse direction, it is more convenient to squeeze out the liquid in the scraper; and the setting of the h value also ensures that when pulling in the reverse direction, as much liquid in the scraper can be squeezed out as much as possible, so that when the lower side is pulled, the scraper can absorb as much liquid as possible.

[0032] (7) The setting of the scraper, on the one hand, can also provide support for the patient above when dragging in the forward direction, thereby increasing the contact area between the entire scraper assembly and the patient and reducing the patient's discomfort. On the other hand, due to the existence of the scraper, the middle part of the cover plate can be subjected to force and thus squeeze the middle part of the scraper, which is further conducive to squeezing out the liquid in the scraper and facilitating the absorption of the liquid when pulling next time. On the other hand, when pulling in the reverse direction, the scraper plays a major scraping role due to the pressure deformation of the upper flying cover plate, which is further conducive to the liquid on and inside the non-woven fabric layer to fall off, and the fallen liquid falls directly to avoid the possibility of being absorbed by the non-woven fabric layer again.

[0033] (8) The middle or upper middle part of the side wall of the guide groove is convex inward. Such a structure enables the side wall of the guide groove to provide a certain upward support for the non-woven fabric layer in the vertical direction, thereby preventing the non-woven fabric layer from sinking too much into the guide groove and causing the scraper to be unable to drag.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1, please refer to Figure 1 - Fig.11,

[0048] A seepage-proof partition comprises a plate body 1, wherein a plurality of guide grooves 3 are arranged at equal intervals on the upper end of the plate body 1, and liquid collecting boxes 2 are arranged at both ends of the plate body 1, the inner cavity of the liquid collecting box 2 is hollow, and a plate body slot 4 is provided on the side of the liquid collecting box 2 facing the plate body 1, and the plate body slot 4 matches the end of the plate body 1, and a guide hole 5 is provided at the position corresponding to each guide groove 3 on the side of the liquid collecting box 2 facing the plate body 1, and the lower edge of the guide hole 5 is aligned with the guide groove 3, and the guide hole 5 is connected to the inner cavity of the liquid collecting box 2, and a scraper 18 is also arranged on the plate body 1, and the length of the scraper 18 is adapted to the width of the plate body 1, and the lower side of the scraper 18 and the upper side of the plate body 1 are in close sliding fit with each other, and a pull rope 19 is provided on the scraper 18, and the length of the pull rope 19 is greater than the width of the plate body 1.

[0049] In this embodiment, preferably, the inner wall of the guide groove 3 is sprayed with a polytetrafluoroethylene coating, the center of the bottom of the guide groove 3 protrudes upward, and the two ends of the bottom of the groove are arranged to be inclined downward outward; the polytetrafluoroethylene coating is arranged to prevent the liquid from adhering to the inner wall of the guide groove 3, thereby improving the diversion effect of the guide groove 3, and the two ends of the bottom of the groove are arranged to be inclined downward outward, so that the liquid falling into the guide groove 3 can automatically flow out to both sides under the action of gravity, thereby improving the diversion effect;

[0050] In the solution of the present application, by setting a scraper bar 18, when there is liquid leakage, by pulling the scraper bar 18, the scraper bar 18 slides between the plate body 1 and the non-woven fabric layer 11. During the sliding, on the one hand, the liquid on the plate body 1 is hung in the guide groove 3. On the other hand, more importantly, when the scraper bar 18 scrapes, it not only scrapes the plate body 1, but also scrapes the non-woven fabric layer 11 and the liquid attached to the lower side of the patient's body, which can squeeze out the liquid inside the non-woven fabric layer 11 and the lower part of the patient's clothes. When the liquid flows out, due to the existence of the scraper bar 18, the squeezed liquid is seriously The scraper strip 18 flows into the chute, so after the scraper strip 18 hangs over the non-woven fabric layer 11, the liquid thereon is greatly reduced, and the non-woven fabric material itself is relatively thin, so the residual liquid can also be quickly evaporated and dried, and this method greatly improves the patient's comfort; further, especially when the liquid is a viscous liquid such as blood, body tissue or gastric juice, this method can directly avoid the problem of these liquids crusting and hardening on the middle sheet, which causes the entire sheet and the patient's clothes to be completely scrapped, and also greatly reduces the risk of these liquids forming pathogens and infections.

[0051] Preferably, along the width direction of the bed body 9, one side of the scraper strip 18 is a wedge-shaped inclined surface, and the other side is a curved surface with a smooth transition from the top to the bottom. The wedge-shaped inclined surface facilitates the scraper strip 18 to enter between the non-woven fabric layer 11 and the plate body 1, and avoids the problem of curling the non-woven fabric layer 11 during the sliding process of the scraper strip 18 along the plate body 1, and the other side of the scraper strip 18 is a curved surface with a smooth transition from the top to the bottom, so that when the scraper strip 18 scrapes under the human body, it can form a squeeze on the lower side of its wedge-shaped inclined surface, and its curved top surface and back can form a larger area of ​​support, reducing the patient's discomfort.

[0052] Preferably, the scraper 18 is made of a deformable and elastic water-absorbing material that can absorb water and restore its shape after the pressure is eliminated. For example, a sponge is used as the scraper 18, and a cover plate 20 is also provided on the scraper 18. The outer wall of the cover plate 20 is smooth. The cover plate 20 extends upward from the lower side of the scraper 18 along the arc surface of the scraper 18 to the top of the scraper 18, covering the arc surface of the scraper 18. The cover plate 20 is made of an elastic hard material that is harder than the scraper 18, such as hard plastic, hard silicone material, etc. By setting the cover plate 20, the cover plate 20 is relatively hard, and when the scraper 18 is hung, the liquid can be pressed out more completely, and the pressed and hung liquid flows down along the front side of the cover plate 20 to the scraper 18, and is directly absorbed by the scraper 18, so as to avoid the problem that the scraped liquid is absorbed by the non-woven fabric layer 11 located above after the scraper 18 passes. When there is too much liquid, it is squeezed by the cover plate 20 during the movement of the scraper 18, and the liquid flows into the guide groove 3 again; when the scraper 18 passes through and reaches the other side of the plate body 1, the pull rope 19 on the other side is pulled to make the scraper 18 pass through between the non-woven fabric layer 11 and the plate body 1 again. In this process, the cover plate 20 faces the side that is opposite to the scraper 1 8 The arc surface that matches the arc surface can also avoid rolling up the non-woven fabric layer 11, and can also squeeze and scrape the non-woven fabric layer 11 again, further squeezing and scraping the liquid thereon, and in this process, since the cover plate 20 is in an arc shape, one side of it is located at the bottom of the scraper strip 18, and the other side is at the top of the scraper strip 18, and the scraper strip 18 below the top of the cover plate 20 is in an open state. During the pull-back process, since the scraper strip 18 is deformable, the cover plate 20 is pressed down, squeezing the liquid adsorbed in the scraper strip 18 out and flowing it into the chute. After such a process, when the scraper strip 18 is pulled between the non-woven fabric layer 11 and the plate body 1 next time, the scraper strip 18 can restore its water absorption performance;

[0053] Moreover, in order to achieve its absorption performance, the absorbent material usually has numerous tiny gaps in its material. When it comes into contact with the non-woven fabric layer 11, there is great friction. Therefore, in the scheme of the present application, the outer wall of the cover plate 20 is smooth and made of elastic hard material, which greatly reduces the friction between the non-woven fabric layer 11 and ensures the good water absorption of the scraper strip 18 while preventing the non-woven fabric layer 11 from wrinkling. Moreover, the force required to pull the scraper strip 18 is greatly reduced.

[0054] Preferably, the upper side of the cover plate 20 covers the upper side of the scraper strip 18 and then extends along the wedge-shaped slope of the scraper strip 18 to form a baffle plate 21. The formation of the baffle plate 21 completely covers the upper edge of the scraper strip 18. With this structure, the friction between the scraper strip 18 and the non-woven fabric layer 11 is completely replaced by the cover plate 20, which greatly improves the service life of the scraper strip 18. In particular, since the scraper strip 18 does not need to consider the friction between the non-woven fabric layer 11, it can be made of a water-absorbing material with a more porous texture and better water-absorbing performance, further improving the absorption capacity of the liquid on the non-woven fabric layer 11; the scraper strip 18 can be made of a material with better water absorption.

[0055] Preferably, the distance between the lower edge of the baffle 21 and the board body 1 is h, and the h value matches the elasticity of the scraper 18, so that when the scraper 18 produces the maximum deformation between the non-woven fabric layer 11 and the board body 1, the lower edge of the baffle 21 does not contact the board body 1.

[0056] Preferably, in a natural state, the upper edge of the cover plate 20 is tilted upward. In the scheme of the present application, in a natural state, the upper edge of the cover plate 20 is tilted upward, that is, the tangent line of the top of the cover plate 20 is tilted upward, firstly, the scraping strength of the upper edge of the cover plate 20 on the non-woven fabric layer 11 is greatly improved. Furthermore, in the scheme of the present application, along the width direction of the bed, the cover plate 20 is in a manner of one side being open and the other side being in contact with the plate body 1, and the direction of the open side is defined as the positive direction, and the direction of the side opposite to the positive direction is defined as the reverse direction. When the scraper bar 18 and the cover plate 20 are dragged forward, the cover plate 20 squeezes and scrapes the non-woven fabric layer 11 on the one hand, so that the liquid on and inside the non-woven fabric layer 11 is scraped off to the scraper bar 18 and sucked in or directly flows into the guide groove 3. Furthermore, the cover plate 20 is fixedly connected to the scraper bar 18. Since the non-woven fabric layer 11, the cover plate 20 is pressed by the patient to form a downward bulging shape, Therefore, during the movement, there is actually a certain upward pulling force on the upper end of the cover plate 20, ensuring that during the movement, the upper edge of the cover plate 20 can be attached to the non-woven fabric layer 11 to achieve a good scraping and squeezing effect. Similarly, when pulling in the opposite direction, a better scraping and squeezing effect can be achieved. Moreover, when the scraper strip 18 and the cover plate 20 are dragged in the forward direction, although the pressure strip is also in a compressed state, the degree of compression is less than that in the reverse pull. That is, when pulling in the forward direction, it is more convenient for the scraper strip 18 to absorb the liquid, and when pulling in the reverse direction, it is more convenient to squeeze out the liquid in the scraper strip 18. The setting of the h value also ensures that when pulling in the reverse direction, as much liquid as possible in the scraper strip 18 can be squeezed out, so that when the lower side is pulled, the scraper strip 18 can absorb as much liquid as possible.

[0057] Preferably, a scraper is also provided on the outer side of the middle part of the cover plate 20, the scraper protrudes toward the side away from the cover plate 20, and the scraper is arranged upwardly and obliquely toward the lower side of the cover plate 20. The arrangement of the scraper, on the one hand, can also form support for the patient above when dragging in the forward direction, increase the contact area between the entire scraper strip 18 assembly and the patient, and reduce the patient's discomfort. On the other hand, due to the existence of the scraper 22, the middle part of the cover plate 20 can be subjected to force and then squeeze the middle part of the scraper strip 18, so that it is further conducive to pressing out the liquid in the scraper strip 18, which is convenient for absorbing the liquid when pulling next time. On the other hand, when pulling in the reverse direction, due to the compression and deformation of the upper flying cover plate 20, the scraper forms the main scraping effect, so that it is further convenient to hang the liquid on and inside the non-woven fabric layer 11, and the hanging liquid falls directly to avoid the possibility of being absorbed by the non-woven fabric layer 11 again.

[0058] Preferably, the middle or upper middle part of the side wall of the guide groove 3 is convex inward. Such a structure enables the side wall of the guide groove 3 to form a certain upward support for the non-woven fabric layer 11 in the vertical direction, thereby preventing the non-woven fabric layer 11 from sinking too much into the guide groove 3 and causing the scraper 18 to be unable to drag.

[0059] In this embodiment, preferably, a drain port 6 is provided at the bottom of the rear side of the liquid collecting box 2, and the drain port 6 is connected to the bottom of the inner cavity of the liquid collecting box 2; the drain port 6 is provided to facilitate the discharge of the liquid in the liquid collecting box 2, and to facilitate the cleaning and disinfection of the inner cavity of the liquid collecting box 2, so as to facilitate the recycling and reuse of the liquid collecting box 2.

[0060] In this embodiment, preferably, the substrate of the board body 1 is made of ABS plastic material, and the outer wall of the board body 1 is wrapped with a polyurethane rubber layer; the structural strength of the board body 1 is ensured by the ABS plastic material substrate, and the comfort of the patient is improved when the upper end of the board body 1 is in contact with the patient by the polyurethane rubber layer.

[0068] The working principle and use process of the present invention are as follows: when the waterproof single is used, the waterproof membrane 10 is fixed to the bed body 9 by the magnetic rubber strips 15 on both sides of the waterproof membrane 10. When a large amount of liquid is about to flow down uncontrollably, gas is pumped into the rubber inflatable column 13 through the one-way valve 14 to expand the rubber inflatable column 13, supporting the non-woven fabric layer 11 to a certain height in front and back, so that a gap is formed in the middle of the non-woven fabric layer 11. A plate body 1 with an absorbent cotton pad 12 at the bottom is inserted into one side of the non-woven fabric layer 11. After the plate body 1 is inserted, the two sides of the absorbent cotton pad 12 are pulled down, and the self-adhesive silicone strips 1 are torn off. 6, the self-adhesive silicone strip 16 is adhered and fixed on the waterproof film 10, and then the two sides of the plate body 1 are sleeved with the liquid collecting box 2 to complete the setting of the plate body 1. When a large amount of liquid seeps down from the non-woven fabric layer 11, it is drained by the guide groove 3 on the plate body 1 and introduced into the liquid collecting boxes 2 on both sides for collection. When the liquid is drained, the liquid collecting box 2 is removed, and then the plate body 1 is pulled out. The wet non-woven fabric layer 11 is directly in contact with the absorbent cotton pad 12, and the absorbent cotton pad 12 absorbs the residual liquid on the non-woven fabric layer 11 to ensure that the non-woven fabric layer 11 is dry, thereby improving the comfort of the patient when using it.
