Description

A hospital bed backrest device

technical field

The utility model relates to a medical device, in particular to a backrest device for a hospital bed.

Background technique

Patients often need to lie on the hospital bed in a semi-recumbent manner after the operation, which can prevent lung infection and bedsores. However, most of the sickbeds in the hospital have single functions at present, and can only be used for patients to rest in bed. Although more advanced sickbeds also have a backrest turning mechanism, due to structural limitations, the handwheel is set at the foot of the sickbed. When getting up, the nursing staff must go to the foot of the bed and turn the handwheel. When the patient sits up, the nursing staff cannot touch the patient, and the patient has no sense of security. Moreover, the structure of this type of turning mechanism is relatively complicated, and the length of the screw rod is relatively large. , high cost and inconvenient to use.

In order to solve the above-mentioned problems of complex structure, lack of sense of security for patients when sitting up, and inconvenient use, a hospital bed backrest device has appeared on the market, which is a structure independent of the bed and can be placed on the bed at any time for patients to lie down It can be used at any time, and can be stored at any time. The backrest device of this kind of hospital bed generally comprises a bottom including a bottom bracket frame, a backrest frame, a turning mechanism capable of turning the backrest frame upwards, a backboard and a pillow, and the lower ends of the straight beams on both sides of the backrest frame are rotatably mounted on the two sides of the bottom bracket frame. On the side, the back board is installed on the back frame, the pillow is installed on the top beam of the back frame, and the turning mechanism is arranged between the bottom support frame and the back frame. When in use, as long as the backrest device is placed on the hospital bed, the backrest frame and the backboard can be turned up to a suitable position through the turning mechanism, and the patient can lie on the backboard in a half-lying position. During the backrest process of the patient, the nursing staff It can keep in touch with the patient all the time, give the patient enough sense of security, has a simple structure and low manufacturing cost.

Yet above-mentioned this sickbed backrest device also has following shortcoming: one, owing to lacking the upward support mechanism to patient's body, patient is quite strenuous when half-lying, and slides down easily to the bed board of sickbed, is difficult to maintain patient's half-lying posture 2. When half-recumbent, the patient sometimes needs to flip slightly to both sides. Even under the care of the nursing staff, the patient still feels that there is a danger of slipping to the sides, which feels very unsafe, so many patients are unwilling to use it. This hospital bed backrest device.

Contents of the invention

The technical problem to be solved by the utility model is to provide a backrest device for a hospital bed, which can make the patient more comfortable and relaxed when half-lying, maintain a better half-lying posture of the patient, and is safer. The technical scheme adopted is as follows:

A backrest device for a hospital bed, comprising a bottom support frame, a backrest frame, a turning mechanism capable of turning the backrest frame upwards, a backboard and a pillow, the lower ends of the straight beams on both sides of the backrest frame are rotatably mounted on both sides of the bottom support frame Above, the backboard is installed in the backrest frame, the pillow is installed on the top beam of the backrest frame, and the turning mechanism is arranged between the bottom bracket frame and the backrest frame, and the feature is: the straight beams on both sides of the backrest frame The armrest mechanism and the two sides of the backboard are also provided with limit bars.

As a preferred solution of the present utility model, it is characterized in that: the armrest mechanism includes an armrest and an armrest strut, one end of the armrest is hinged to the straight beam of the backrest frame, the lower surface of the other end of the armrest is provided with an armrest card slot, and the armrest strut One end is hinged with the straight beam of the backrest frame and is located under the armrest, and the other end of the armrest support rod is located in the card slot of the armrest. The armrests, armrest stays and straight beams of the backrest frame form a triangular stable support structure. When the backrest device is to be stored away, the handrails and handrail stays are stored close to the straight beams of the backrest frame, saving storage space. The armrest mechanism can also only include the armrest, and the straight beam of the backrest frame is provided with a clamping hole, and one end of the armrest is clamped in the clamping hole, and when the backrest device is to be stored, the armrest is pulled out from the clamping hole.

As a preferred solution of the present utility model, it is characterized in that: the turning mechanism includes a backrest support rod and a plurality of backrest clamping slots arranged on the side of the bottom bracket frame; one end of the backrest support rod is hinged with the straight beam of the backrest frame, and the backrest The other end of the strut is in the slot of the backrest. When the back support bar is removed from the backrest slot, the back frame can be folded with the bottom bracket frame; when the end of the back support bar is put into the backrest slot, the back frame can be turned upward; by adjusting the end of the back support bar The upper part is in different backrest slots, so as to adjust the upward flipping range of the backrest frame. flip mechanism is ok

As a further preferred solution of the utility model, it is characterized in that: from the two sides of the backboard to the middle, the longitudinal section area of the limiting strip gradually decreases. There is a smooth transition between the limit bar and the backboard, and the structure is more reasonable. When the patient rolls over, he will not be oppressed by the obviously protruding limit bar and cause pain.

As a further preferred solution of the utility model, it is characterized in that: the backboard is provided with a plurality of ventilation holes. It makes the patient's back ventilated, which is comfortable and prevents the occurrence of bedsores.

As a further preferred solution of the present utility model, it is characterized in that: the cross-section of the pillow is circular or oval. The cross-section of the pillow is round or oval, which is more comfortable and more scientific and reasonable.

Compared with the prior art, the utility model has the following advantages: when the patient is half-lying, the arm is hung on the armrest mechanism, which is more comfortable and relaxed, and the armrest mechanism plays an upward supporting role for the patient to maintain the patient's better half-lying position Posture: By setting the limit bar, the patient will not fall from both sides when turning over, ensuring the safety of the patient and giving the patient a sense of security.
