Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a restraint seat for infusion. Background Art

[0002] Patients with mental disorders usually have disordered brain function and varying degrees of impairment in their mental activities such as cognition, emotion, behavior and will.

[0003] Patients with mental disorders may experience symptoms such as madness and behavioral disorders when they are ill. When they are receiving infusion treatment, once they encounter an attack, due to their lack of self-awareness and controllable consciousness, their limbs will move randomly, which may easily cause the infusion needle to be pulled out or fall off, not only prone to needle stick injuries, but also affecting the progress of infusion treatment. Utility Model Content

[0004] The utility model aims to provide a restraint seat for infusion, which can be used to restrain the hands of patients with mental disorders to prevent the infusion needle from being pulled out or falling off due to upper limb behavior disorder during infusion treatment.

[0005] The utility model is realized by the following technical solutions:

[0006] A restraint chair for infusion, comprising a chair body with two armrests, wherein pads are installed on the top ends of the two armrests of the chair body, wherein a restraint clamp for fixing the patient's infusion hand is installed on the top surface of one of the pads, so that the patient's infusion hand can be fixed on the pad, and a restraint belt for binding and restraining the patient's other hand is installed on the top surface of the other pad. When bound by the restraint belt, the patient's non-infusion hand has a certain range of movement space, so that the patient can use the hand to drink water, operate a mobile phone, etc., but the patient's non-infusion hand cannot touch the restraint clamp and the infusion hand, so as to prevent the patient from pulling out the infusion needle due to sudden mental disorder.

[0007] Furthermore, the pad can be detachably mounted on the top of the armrest of the seat body, the two pads can be interchanged, and the restraint clamp can be adjusted in installation position along with the pad, so that the installation position of the restraint clamp on the seat body can be adjusted according to the patient's infusion hand, making it convenient to use the restraint clamp to fix the patient's infusion hand.

[0008] Furthermore, the pad and the handrail are detachably connected via a first bolt, which facilitates disassembly and assembly.

[0009] Furthermore, two limit plates spaced apart in the left-right direction are fixed to the bottom end surface of each pad, and a slot for clamping the armrest is formed between the pad and the two limit plates, which can improve the stability of the pad when installed on the top of the armrest and prevent the pad from tipping over.

[0010] Furthermore, the restraint clamp includes an arc-shaped splint, and the left and right ends of the arc-shaped splint are integrally formed with flanges. Two hinged seats spaced along the front-to-back direction are fixedly installed on the top surface of one of the pads. One of the flanges of the arc-shaped splint is hinged to the two hinged seats, so that the arc-shaped splint can be rotated, and the other flange of the arc-shaped splint and the pad can be detachably connected by a second bolt. When the arc-shaped splint is flipped open, the patient's infusion hand can be placed on the top surface of the pad, and then the arc-shaped splint is flipped over so that it cooperates with the pad to clamp and fix the patient's infusion hand, and the second bolt is installed to fix the arc-shaped splint on the pad.

[0011] Furthermore, a finger restraint plate is fixedly installed on the top surface of one of the pads, and the finger restraint plate is located on the front side of the arc-shaped splint. Four limit holes are opened on the finger restraint plate, all of which penetrate along the front-to-back direction. The four limit holes are used to wear the other four fingers of the patient's infusion hand except the thumb. When the patient's infusion hand is clamped and fixed on the pad by the restraint clamp, the four fingers are respectively inserted into the four limit holes, which can improve the stability of the clamping and fixation of the infusion hand and prevent the patient's infusion hand from shaking drastically.

[0012] Furthermore, the top surface of each pad, the inner wall surface of the arc-shaped clamping plate and the inner wall surface of each limiting insertion hole are fixedly installed with a soft bottom layer, which can prevent pressure sores and improve comfort.

[0013] Furthermore, the restraint belt is composed of a wrap and a connecting belt, one end of the connecting belt is fixed on the pad, and the other end of the connecting belt is fixedly connected to the middle part of the wrap, and the two ends of the wrap are detachably connected by Velcro; when the restraint belt is used to bind the patient's non-infusion hand, the wrap is wrapped around the wrist of the non-infusion hand, and the two ends of the wrap are connected by Velcro to bind and restrain the patient's non-infusion hand.

[0014] Furthermore, the length of the connecting belt is not greater than half of the distance between the two armrests, so as to avoid the connecting belt being too long and causing the non-infusion hand of the patient to touch the restraint clamp and the patient's infusion hand when the strap is used to bind the patient's non-infusion hand.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The restraint seat can be used to restrain the hands of patients with mental disorders when they receive infusion treatment, so as to prevent the patients from pulling out the infusion needle or committing other harmful behaviors due to sudden mental disorders; by installing a restraint clamp and a restraint belt on the top of the two armrests of the seat body respectively, the restraint clamp and the pad are used to clamp and fix the patient's infusion hand, and the restraint belt is used to tie and restrain the patient's non-infusion hand. Since the restraint belt has a certain length, the patient's non-infusion hand has a certain range of movement space, so that the patient can use this hand to drink water, operate a mobile phone, etc., but due to the length limit of the connecting belt, the patient's non-infusion hand cannot touch the restraint clamp and the infusion hand, so as to prevent the patient from pulling out the infusion needle due to sudden mental disorders, and avoid needle stick injuries caused by upper limb behavior disorder during infusion treatment and affect the infusion treatment process.

[0036] The specific method of using the restraint seat in this embodiment is as follows:

[0037] When a patient with a mental disorder receives infusion treatment, the restraint seat can be used to restrain the patient's hands to prevent the patient from pulling out the infusion needle or engaging in other harmful behaviors due to a sudden mental disorder;

[0038] The patient sits on the chair body 1, and taking the patient's left hand as the infusion hand as an example, the installation positions of the restraint clamp 3 and the restraint belt 4 are as follows: Figure 1 If the patient's right hand is the infusion hand, Figure 1 The positions of the two pads 2 are exchanged, thereby exchanging the positions of the restraining fixture 3 and the restraining belt 4;

[0039] Flip open the arc splint 2.1, place the patient's infusion hand on the pad 2, insert four fingers into the four limit holes 8 on the finger restraint plate 7 respectively, flip the arc splint 2.1 and install the second bolt 2.3, use the second bolt 2.3 to fix the arc splint 2.1 on the pad 2, and the arc splint 2.1 cooperates with the pad 2 to clamp and fix the patient's infusion hand;

[0040] Wrap the strap 4.1 of the restraint belt 4 around the wrist of the patient's non-infusion hand, and connect the two ends of the strap 4.1 with Velcro 10 to bind and restrain the patient's non-infusion hand. Since the connecting strap 4.2 has a certain length, the patient's non-infusion hand has a certain range of activity space, so that the patient can use this hand to drink water, operate a mobile phone, etc. However, due to the length limitation of the connecting strap 4.2, the patient's non-infusion hand cannot touch the restraint clamp 3 and the infusion hand, so as to prevent the patient from pulling out the infusion needle due to sudden mental disorder;

[0041] The restraint seat can be used to restrain the hands of patients with mental disorders to prevent the infusion needle from being pulled out or falling off due to upper limb behavior disorder during infusion treatment. In addition, a foot restraint mechanism for binding the patient's feet, such as a splint or ankle restraint strap, can be installed on the supporting feet of the seat body 1 to restrain the feet.
