Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a medical soft and hard mattress for preventing pressure injuries. Background Art

[0002] In clinical practice, especially in intensive care units, patients are bedridden for a long time due to various diseases. For patients with limited mobility, due to their inability to frequently turn over and change their sleeping positions, pressure injuries are likely to occur. Pressure injuries are local injuries to the skin and / or subcutaneous tissue caused by pressure or the combination of pressure and shear force, usually located at bony prominences, but may also be related to pressure caused by medical devices or other objects. During the blood flow through the skin and subcutaneous tissue, it is blocked by continuous pressure exceeding capillary pressure, and nutrients cannot be supplied to the skin and subcutaneous tissue in a timely manner, gradually resulting in skin tissue necrosis and ulcers. This disease not only increases the probability of patients developing complications but also brings more pain to them. Clinically, in order to prevent pressure injuries, air mattresses are mostly used on patients' beds. However, patients are prone to sliding on air mattresses, which affects their activities in bed, and the air mattresses have poor air permeability, affecting the comfort of use. Some conscious patients complain that the overly soft mattress affects their sleep and they do not feel fully rested. Most of the current clinical mattresses have a single softness and hardness and do not have the function of preventing pressure injuries. Therefore, the utility model designs a medical soft and hard mattress for preventing pressure injuries. Content of the Utility Model

[0019] The present utility model will be specifically described below in conjunction with the accompanying drawings.

[0020] As shown in the attached Figure 1 to the attached Figure 4 , Specific embodiments:

[0022] A medical soft and hard mattress for preventing pressure injuries includes a foldable mattress body 1 and a sheet 2. The upper and lower surfaces of the mattress body 1 are a soft surface and a hard surface respectively. The mattress body 1 can be flipped so that the soft surface or the hard surface faces upward on the bed frame. The sheet 2 can be laid on the upward soft surface or hard surface. A plurality of inflatable pads 3 are provided on the sheet 2, and are respectively fixed at positions corresponding to the elbows, sacrococcygeal regions, heels and scapular regions of the patient. An inflation tube 4 is provided on the inflatable pad 3, and a plug connector 5 is provided at the end of the inflation tube 4. The plug connector 5 can be inserted into an insertion hole 6 provided on the soft surface and / or the hard surface. A through hole 7 corresponding to the position of the insertion hole 6 is provided on the sheet 2. The insertion hole 6 is connected to a one-way inflation connector 8 through a pipe inside the mattress body 1. The one-way inflation connector 8 is provided on the side surface of the mattress body 1. The one-way inflation connector 8 is connected to an air pump through an external pipeline.

[0023] When the medical soft and hard mattress for preventing pressure injuries of the present utility model is in use, first flip the mattress body 1 according to the needs of the patient so that the soft surface or the hard surface faces upward. Since the mattress body 1 is foldable, the length can be shortened after folding, which is convenient for flipping. After flipping, lay the sheet 2 on the upper end of the mattress body 1, insert each plug connector 5 of the inflatable pad 2 into the corresponding insertion hole 6, connect the air pump to the one-way inflation connector 8, let the patient lie flat on the sheet 2, and the air pump starts to inflate. The inflatable pads 3 bulge to support the elbows, sacrococcygeal regions, heels and scapular regions of the patient where pressure injuries are likely to occur.

[0024] The inflatable pad 3 is fixed on a support pad 9. A fixing area 10 corresponding to each inflatable pad 3 is provided on the sheet 2. The support pad 9 is detachably arranged at any position in the fixing area 10. The fixing area 10 is designed according to patients of different heights and body types. For example, for the fixing area corresponding to the elbow, in the lying state of patients of different heights and body types, the possible positions where the elbows are placed are all within the fixing area, so that the position of the inflatable pad 3 corresponding to the elbow can be adjusted to meet the needs of patients of different heights and body types.

[0025] Specifically, the support pad 9 is adhered to the fixing area 10 on the inflatable pad 3 through a magic tape. Preferably, the back surface of the support pad 9 is provided with a magic tape hook surface, and the fixing area 10 of the sheet 2 is provided with a magic tape fluff surface. The magic tape hook surface is likely to scratch the patient's skin and is not suitable to be arranged on the sheet 2.

[0026] It should be noted that when the patient sleeps on the side, the parts prone to pressure injury are the outer ankle, the lateral side of the knee joint, the greater trochanter, the rib, and the acromioclavicular joint. The above-mentioned fixed area 10 preferably covers the parts prone to pressure injury when the patient sleeps on the side, which is convenient for adjustment to adapt to patients who are used to sleeping on the side.

[0027] The inflatable cushion 3 is in a U-shaped horseshoe shape, and the two ends of the inflatable cushion 3 are close to each other and form a groove at its center for accommodating the patient's elbow, sacrococcygeal region, heel or scapular region. The groove can protect the prominent bones of these parts of the body and avoid causing injuries.

[0028] A pressure sensor 11 is provided at the central groove of the inflatable cushion 3 corresponding to the patient's sacrococcygeal region. The pressure sensor 11 is fixed on the support cushion 9. The first adapter 12 is provided on both the soft surface and the hard surface of the mattress body 1. The transmission adapter of the pressure sensor 11 is inserted into the first adapter 12. The second adapter 13 is provided on the side of the mattress body 1. The second adapter 13 and the first adapter 12 are connected by a signal transmission line built in the mattress body 1. The second adapter 13 and the air pump are both connected to the controller. When the patient lies flat, initially the inflatable cushion 3 is not inflated. When the patient's sacrococcygeal region contacts the pressure sensor 11, the controller receives the signal and starts the air pump to inflate all the inflatable cushions 3. When the sacrococcygeal inflatable cushion 3 is fully inflated, the patient's sacrococcygeal region no longer contacts the pressure sensor 11, the pressure signal decreases or disappears, and the inflation stops.

[0029] The mattress body 1 is composed of three sub-mattresses 101. The adjacent sub-mattresses 101 are connected by a flexible connecting strip 102. The connecting strip 102 is a cloth strip, and one of the sub-mattresses 101 can be folded to the top of its adjacent sub-mattress 101 for folding. The three-section mattress design not only meets the use of some nursing beds that require adjustment of the head and foot of the bed height, but also facilitates flipping the mattress to exchange the soft and hard surfaces after folding, making the operation more convenient.

[0030] Although the present utility model has been disclosed above with preferred embodiments, they are not used to limit the present utility model. Any person skilled in this art can make various changes or modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be defined by the protection scope of the claims of this application.
