Example 2

An injection chair is shown in fig. 3, and is different from embodiment 1 in that the upper end of a mounting hole 6 is provided with a storage groove 7 communicated with the mounting hole 6, an infusion rod 52 is arranged in the storage groove 7, an end cover 8 matched and sealed with the storage groove 7 is further arranged on an armrest 4, and the upper end face of the end cover 8 is flush with the upper end face of the armrest 4.

The utility model is provided with the containing groove for placing the transfusion rod, when the patient does not need to transfuse, the lifting rod is collected into the mounting hole, the transfusion rod is collected into the containing groove, and then the end cover is covered, so that the upper surface of the end cover is flush with the upper surface of the handrail, thus hands can not be knocked when the patient places the arm on the handrail; the device is simple and comfortable to use.

Example 3

The utility model provides an injection chair, as shown in fig. 4, different from embodiment 1, seat support 1 with be equipped with angle adjusting device 9 between the back of the chair 3, angle adjusting device 9 include respectively with two shaft couplings 91 that articulated shaft 2 is connected, connect the connecting rod 92 of two shaft couplings 91, cup joint in worm wheel 93 on the connecting rod 92 and with worm wheel 93 meshed worm 94, seat support 1 with be equipped with the through-hole 95 that runs through to relative terminal surface on the terminal surface of one side is connected to the back of the chair 3, the one end axostylus axostyle of worm 94 passes through-hole 95 and outside extension, and stretch out through-hole 95 install knob 96 on the worm 94.

The utility model discloses in set up the angle adjusting device between seat support and the back of the chair for adjust the back of the chair, when the patient need to beat the belly skin needle, can be through the back of the chair leveling, make the patient lie and treat, and beat the hip needle or when the patient needed to have a rest in the dizzy blood, can twist the knob soon, the rotation of knob drives the worm and rotates, and worm wheel mesh, thus drive the worm wheel and rotate, and the rotation of worm wheel can drive the articulated shaft through the connecting rod and rotate, thus adjust the angle between the back of the chair and the seat support; the angle adjusting device can enable the patient to carry out hip-beating through lying, semi-lying, lying on the side and other postures, and is reasonable in design and simple to use.

Further, to illustrate the working principle of the chair back angle adjustment, the following is clarified: the angle adjusting device is arranged between the chair seat and the chair back to adjust the angle between the chair back and the chair seat, when a patient needs to open the belly skin needle, the patient can lie down for treatment by leveling the chair back, and when the patient opens the belly skin needle or the patient suffers from blood faint and needs to have a rest, the chair back is adjusted to a comfortable angle through the angle adjusting device; when the chair is used, the knob is rotated, the rotation of the knob drives the worm to rotate, the worm is meshed with the worm wheel so as to drive the worm wheel to rotate, and the rotation of the worm wheel can drive the articulated shaft to rotate through the connecting rod so as to adjust the angle between the chair back and the chair seat; because the angle between the chair back and the chair seat is adjusted by the worm gear, when the worm gear does not work, the rotation of the chair back cannot be controlled only by the hinge shaft, so the worm gear not only can adjust the angle between the chair back and the chair seat, but also can be used as a limiting component; the angle adjusting device can enable the patient to carry out hip-beating through lying, semi-lying, lying on the side and other postures, and is reasonable in design and simple to use.

Example 4

As shown in fig. 5, different from embodiment 1, a lifting device 10 is mounted on a lower end surface of a seat 1, the lifting device 10 includes a base 101, a sleeve 102 mounted on the base 101, a power device 103 disposed in the sleeve 102 and mounted on the base 101, and a piston rod 104 disposed on the power device 103, a top end of the piston rod 104 is mounted on the lower end surface of the seat 1, and a control rod 105 is disposed on the power device 103; the sleeve 102 is formed by sleeving a plurality of barrel bodies with sequentially decreasing barrel diameters, the lower end face of the seat 1 is arranged on the barrel body with the smallest barrel diameter, and one end of the control rod 105 penetrates through the side wall of the barrel body with the largest barrel diameter and extends outwards.

The utility model discloses a lifting device is arranged in order to adjust the height of the chair seat according to the height of the patient, when in use, the medical staff steps on or manually presses the control rod, the control rod presses the power device to start the power device, the start of the power device drives the piston rod to lift, thereby adjusting the lift of the chair seat, the pneumatic device adopts lifting devices such as a jack or an air cylinder, and the power device can adopt a device with an automatic lifting mode or a device with a manual lifting mode, in this embodiment, the manual lifting is taken as an example; the device simple structure, convenient to use, the clinical use of especially adapted reality has higher application and spreading value.

Further, to illustrate the principle of seat height adjustment, the following clarifies: in the embodiment, because the power device adopts lifting devices such as a jack or an air cylinder, the piston rod and the control rod are part of the jack or the air cylinder; the sleeve is arranged in a telescopic mode, so that when the lifting device controls the lifting of the seat, the sleeve is telescopic along with the lifting of the lifting device, the phenomenon that the height of the seat is influenced by the fixation of the sleeve is avoided, and therefore the lifting device can be used as a power device and a limiting device for the telescopic sleeve.

The sleeve is arranged in a telescopic mode in the embodiment, so that when the lifting device controls the lifting of the seat, the sleeve is telescopic along with the lifting of the lifting device, the fixing of the sleeve is avoided, the height of the seat is prevented from being influenced, and therefore the lifting device can be used as a power device and a limiting device for telescopic sleeve.
