Technical Field

[0001] This utility model relates to the field of hospital bed technology, specifically a hospital bed connection device. Background Technology

[0002] Hospital beds generally refer to nursing beds, which are designed according to the patient's treatment needs and bedridden lifestyle. They are designed to allow family members to accompany the patient and have multiple nursing functions and operation buttons. They are insulated and safe beds, with functions such as weight monitoring, back support for meals, intelligent turning over, prevention of bedsores, negative pressure urination and bedwetting alarm monitoring, mobility and transportation, rest, rehabilitation (passive movement, standing), and drug administration and infusion. Rehabilitation beds can be used alone or in conjunction with treatment or rehabilitation equipment. The guardrails on both sides of the bed prevent the patient from slipping off the bed and assist in getting up.

[0003] A published patent document with announcement number CN215350149U discloses a hospital bed rail connecting device. This published patent document includes a connecting body, which is a right-angled triangle. The connecting body has connecting holes at the two right-angled sides away from the right angle, and a groove at the right angle. The groove has fixing holes on both sides, and a fixing device is connected inside the groove. The fixing device includes a fixing plate, a fixing hook, and a mating hole. The fixing plate mates with the groove, and the mating hole is located on the fixing plate. A connecting rod passes through the mating hole and connects to the connecting body. The fixing hook connects to the fixing plate. This solves the problem of hospital beds needing to be frequently flipped up and down. However, the aforementioned published patent document can only realize the up and down flipping function of the railing, but cannot flip the railing to the required angle for fixing, resulting in poor flexibility of use.
