[0002] Injection therapy is a commonly used treatment method in clinical practice. Depending on the location of the needle reaching the human tissue, injection therapy is divided into different specific treatment methods such as intradermal injection, subcutaneous injection, intramuscular injection and intravenous injection. Different injection treatment methods have different clinical applications. Compared with other treatment methods, injection therapy can make the drug absorbed faster, so as to achieve the therapeutic effect faster. In addition, some special drugs cannot enter the human body through oral administration, such as insulin, etc. They must enter the human body through injection therapy to achieve the therapeutic effect.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0026] like Figure 1 to Figure 6 As shown, the embodiment discloses a multifunctional children's injection bed chair, which is mainly composed of a cushion 1, a base 2, a backrest 3, a leg support 4 and an arm support device. The base 2 is installed at the bottom of the cushion 1, and the height of the base 2 can be raised and lowered. The bottom of the base 2 is provided with a caster 5 with a brake to facilitate the movement and parking of the injection bed chair. The backrest 3 is hinged at the rear end of the cushion 1 and can be adjusted in pitch, and the leg support 4 is hinged at the front end of the cushion 1 and can be adjusted in pitch; when the backrest 3 and the leg support 4 are laid flat, the present invention is in the form of a bed, and the patient can lie or lie prone; when the backrest 3 is raised and the leg support 4 is put down, the present invention is in the form of a chair, and the patient can maintain a sitting position. The arm support device is installed on the cushion 1, and the arm support device is used to provide support and fixation for the patient's arm. The pitch adjustment structure of the above-mentioned backrest 3 and leg support 4 can adopt the existing technology, which is not particularly limited here.

[0027] In clinical applications, since the positions of the patient's arms are different when the patient is lying down and sitting up, in order to provide reasonable and comfortable support and fixation for the patient's arms in different positions, the present invention designs the following arm support device.

[0028] like Figure 1 to Figure 4As shown, the arm support device is mainly composed of a mounting shaft 6, a swivel seat 7, an L-shaped support rod 8, a crossbeam 9 and an arm support 10. The mounting shaft 6 is fixedly mounted on the bottom of the seat cushion 1, the swivel seat 7 is rotatably mounted on the lower end of the mounting shaft 6, the end of the crossbar 8a of the L-shaped support rod 8 is connected to the swivel seat 7, the swivel seat 7 can drive the vertical rod 8b of the L-shaped support rod 8 to rotate around the rear part of the seat cushion 1, and a swivel locking mechanism is arranged between the swivel seat 7 and the mounting shaft 6 to lock the vertical rod 8b to the left or right side of the seat cushion 1; the rear end of the crossbeam 9 is rotatably mounted on the upper end of the vertical rod 8b and can be locked at any position, and a height-adjustable arm support 10 is installed on the crossbeam 9; a swing drive mechanism is installed in the swivel seat 7, the end of the crossbar 8a is connected to the swing drive mechanism, and the swing drive mechanism can drive the vertical rod 8b of the L-shaped support rod 8 to swing back and forth for adjustment.

[0029] When the present invention is in the form of a chair [see Figure 1 】, at this time, the arm support device is in the front support position. In this position, the upper end of the vertical rod 8b of the L-shaped support rod 8 is inclined toward the leg support 4, and the crossbeam 9 and the arm support 10 are located on the side of the cushion 1. At this time, the patient's arm that needs to be supported can be comfortably placed on the arm support 10. If the other arm needs to be supported, it is only necessary to unlock the swivel locking mechanism, so that the swivel seat 7 can drive the vertical rod 8b of the L-shaped support rod 8 to rotate to the other side of the cushion 1 through its own rotation [see Figure 2 ], the crossbeam 9 and the arm support 10 will also rotate to the other side along with the vertical rod 8b, and then be locked when they are in place.

[0030] When the present invention is in the form of a bed, if the arm support device is in the front support position, it will not be compatible with the position of the patient's arm when lying down, and this requires adjustment. The specific adjustment method is: first use the swing drive mechanism in the swivel seat 7 to drive the vertical rod 8b of the L-shaped support rod 8 to swing backward, so that the upper end of the vertical rod 8b of the L-shaped support rod 8 turns to tilt toward the head end of the backrest 3; then unlock the connection between the rear end of the crossbeam 9 and the upper end of the vertical rod 8b, rotate the crossbeam 9 180 degrees and then lock it again. At this time, the crossbeam 9 and the arm support 10 are located on one side of the backrest 3, which can adapt to the position of the patient's arm when lying down, and the patient's arm can be comfortably supported [see Figure 3 】.

[0031] In this embodiment, the rotary locking mechanism is mainly composed of an electromagnetic lock 11 and a lock ring 12. The electromagnetic lock 11 is fixedly mounted on the top of the rotary seat 7, the lock pin head of the electromagnetic lock 11 faces the mounting shaft 6, and the switch of the electromagnetic lock 11 is mounted on the crossbeam 9; the lock ring 12 is fixedly mounted on the mounting shaft 6 at a position directly opposite to the lock pin head, and locking recesses for inserting the lock pin are provided on both sides of the outer surface of the lock ring 12. In this arrangement, when the crossbeam 9 and the arm support 10 in the arm support device are located on one side of the seat cushion 1 and are locked, the lock pin of the electromagnetic lock 11 is inserted into the locking recess on one side. When the arm support device needs to be rotated to the other side of the seat cushion 1, the switch of the electromagnetic lock 11 is first pressed to retract the locking pin and disengage the locking recess. At this time, the swivel seat 7 can rotate around the mounting axis 6. When the swivel seat 7 drives the L-shaped support rod 8, the cross beam 9 and the arm support 10 to rotate to the other side of the seat cushion 1, the switch of the electromagnetic lock 11 is released, and the locking pin extends forward and is inserted into the locking recess on the other side, and the arm support device is locked.

[0032] In this embodiment, the rear end of the cross beam 9 is provided with a plug-in platform 9a extending downward, the upper end of the vertical rod 8b is inserted into the plug-in platform 9a, and the side wall of the plug-in platform 9a is provided with a locking hand wheel 16. When in use, the locking hand wheel 16 is loosened, and the rear end of the cross beam 9 can rotate freely around the upper end of the vertical rod 8b, and the locking hand wheel 16 can be tightened again after the rotation is adjusted to the right position.

[0033] In this embodiment, the vertical rod 8b includes an upper rod section 8b.1 and a lower rod section 8b.2, and the upper rod section 8b.1 and the lower rod section 8b.2 are sleeved and connected and can be telescopically adjusted. The docking station 9a is arranged at the upper end of the upper rod section 8b.1, and the axial center line of the docking station 9a and the center line angle of the crossbeam 9 are greater than 90 degrees [preferably 120 degrees]. The purpose of such arrangement is that for patients of different heights, their body positions when lying down will be different, and the height requirements of the arm support 10 will also be different. Generally speaking, people with short bodies will require the arm support 10 to be lower and closer to the cushion 1. At this time, the arm support 10 can be lowered by shortening the length of the vertical rod 8b, and because the axial center line of the docking station 9a and the center line angle of the crossbeam 9 are greater than 90 degrees, in the bed form, when the vertical rod 8b is shortened, the arm support 10 will also move toward the cushion 1, so that two needs can be met with one adjustment.

[0034] In this embodiment, the swing drive mechanism includes a worm wheel 13, a worm 14 and a hand wheel 15. The worm wheel 13 is fixedly mounted on the cross bar 8a, the worm 14 is arranged beside the worm wheel 13 and meshes with the worm wheel 13, and both ends of the worm 14 are rotatably connected to the swivel seat 7 and penetrate the swivel seat 7 to be exposed and respectively mounted with hand wheels 15. In this arrangement, even if the direction of the swivel seat 7 changes after rotation, it can be ensured that the hand wheel 15 always faces outward, which is convenient for adjustment.

[0035] In this embodiment, a square groove is provided on the top of the cross beam 9, and a square block 10a matching the shape of the square groove is provided at the bottom of the arm support 10. The square block 10a is movably installed in the square groove. A rotatable adjustment handle 17 is installed at the bottom of the cross beam 9. The screw of the adjustment handle 17 penetrates upward into the square groove and is threadedly connected with the square block 10a. With such an arrangement, the height of the arm support 10 can be fine-tuned by screwing the adjustment handle 17, which is conducive to providing the patient's arm with the most comfortable support. In addition, the square block 10a at the bottom of the arm support 10 is arranged to be biased to one end, so that the arm support 10 can be taken out and turned 180 degrees according to the use requirements, further enriching the adjustment flexibility of the arm support 10.

[0036] In addition, the injection bed chair of the present invention can also be provided with a restraint belt assembly [not shown in the figure] as needed. The restraint belt assembly includes an arm restraint belt arranged on the arm support 10, and / or a hip restraint belt arranged on the seat cushion 1, and / or an upper body restraint belt arranged on the backrest 3, and / or a lower limb restraint belt arranged on the leg support 4. In this way, for patients with poor cooperation, one or more restraint belts can be used for auxiliary fixation to improve the safety of injection treatment. The restraint belt can be a conventional product, and its form is varied, so it is not particularly limited here.

[0037] In this embodiment, an infusion auxiliary device is also installed on the crossbeam 9. The infusion auxiliary device is used to allow the patient's hands to maintain a suitable infusion posture during intravenous infusion, thereby improving the safety of infusion and the comfort of the patient.

[0038] In this embodiment, the infusion auxiliary device includes a liquid storage seat 18, a delivery pump and an elastic hollow gripping ball 19. The liquid storage seat 18 is installed at the front end of the cross beam 9, and liquid is stored inside the liquid storage seat 18; the top of 18 and the rear end of the cross beam 9 are both provided with a mounting joint 20 for mounting the elastic hollow gripping ball 19, and the inner end of the mounting joint 20 is connected to the inside of the liquid storage seat 18 through a pipeline via a delivery pump, and the liquid inside the liquid storage seat 18 can be transported to the elastic hollow gripping ball 19 through the pipeline by the delivery pump to expand the elastic hollow gripping ball 19, and a heating element for heating the liquid is also provided inside the liquid storage seat 18. With such a configuration, when the present invention is transformed between the bed form and the chair form, the position of the arm support 10 also needs to be changed accordingly, and at this time, the installation position of the elastic hollow gripping ball 19 can be changed for adaptation [the arm support 10 also needs to adjust the installation direction according to the situation]. Since the elastic hollow gripping ball 19 can expand and contract, for patients with different palm sizes, the size of the elastic hollow gripping ball 19 can be adjusted for adaptation. In low-temperature seasons, a heating element can be used to heat the liquid in the liquid reservoir 18 to keep the elastic hollow gripping ball 19 at a suitable temperature, further improving the comfort of the patient. The heating element can be a conventional product in the prior art, and is not specifically limited here.

[0039] In this embodiment, a storage box 21 is installed on the upper part of the back of the backrest 3, and the upper part of the inner side of the storage box 21 is connected to the backrest 3 through a damping hinge. This arrangement can facilitate the storage and placement of commonly used items, and no matter what angle the backrest 3 is placed, the storage box 21 can be unfolded and placed vertically and the position can be kept stable through the damping hinge. A drawer can be set in the storage box 21 or a flip-top storage box can be used to place items, which is not limited here.

[0040] The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by a person of ordinary skill in the art based on the above description shall fall within the scope of protection of the present invention.
