Description

Multifunctional infusion chair

Technical Field

The invention specifically relates to a multifunctional infusion chair.

Background technique

An infusion chair is a chair used for patients receiving infusions. It is also called an IV chair or a hanging bottle chair. It is mainly used in medical units to give infusions to patients. A traditional infusion chair is a chair for patients to sit on for infusions. It has a single function and poor comfort. With the development of society and productivity, infusion chairs have evolved from simple chairs to multifunctional, comfortable, safe, and environmentally friendly ones. They can also take better care of patients in terms of ease of use.

The infusion chairs currently used in hospitals and medical institutions have relatively single functions and the following disadvantages:

1. The temperature of the infusion chair cannot be adjusted. In the cold winter, when the patient is receiving an infusion, the infusion temperature is low, and the patient's hands will become cold when the infusion is delivered to the patient. In addition, the patients who come for infusion are usually weak and more likely to feel cold. The infusion patients are prone to catching cold, which aggravates their condition and is not conducive to recovery. In order to solve this problem, people usually use traditional heating methods such as warm water bags and hot water bottles, but the temperature fluctuates and is extremely inconvenient to use. Alternatively, air conditioning is used to increase the temperature of the infusion room, but this method of increasing the ambient temperature consumes a lot of energy;

In summer, due to the high ambient temperature and the fact that the surface of a general infusion chair is made of waterproof leather or imitation leather material for easy cleaning, the air permeability is poor, so patients are more likely to sweat, causing physical discomfort to patients.

2. The infusion chair does not have the ability to monitor infusion. During the infusion process, medical staff and patients need to pay close attention to the infusion situation to ensure that they can promptly detect and take appropriate treatment measures when the medicine is finished. However, when patients are receiving infusions, especially at night, they can easily forget to check whether the medicine has been finished due to various reasons. When there are many patients, medical staff may not be able to detect the end of the medicine in time, and the patient will experience blood return or local tissue swelling. In order to solve this problem, a monitor is currently used for monitoring. After the medicine is finished, the monitor beeps to remind, but the existing monitor only has detection and beeping effects and cannot intervene. When the patient falls asleep or the medical staff does not hear it, the patient's hand will still experience blood return or local tissue swelling.

3. It is inconvenient to fix the infusion chair after it is moved. In order to facilitate the movement of the infusion chair, the existing infusion chair will install several self-locking universal wheels at the bottom. The position of the infusion chair is moved by the universal wheels. When the movement is completed, the universal wheels are locked to prevent the infusion chair from moving. However, the contact area between the universal wheels and the ground is small, and the patient is prone to shaking when sitting on it, causing the infusion chair to move.

4. Currently, only one patient can sit on an infusion chair. When a patient is accompanied by a caregiver, the caregiver can only sit on the infusion chair adjacent to the patient, occupying the seats of other patients and affecting the infusion of other patients. To solve this problem, a caregiver stool is placed next to each infusion chair. However, the caregiver stool takes up space when not in use, and it is easy to be moved and lost because it has no fixed placement.

5. The height of the infusion pole on the existing infusion chair is inconvenient to adjust, and the patient has to hold the infusion pole in one hand when walking, for example, to the toilet, which is inconvenient to use.

6. In order to facilitate patients to eat and place their belongings, the existing infusion chair will add a small table on the seat. However, in order to facilitate patients to get in and out, the size of the small table is small and the things placed on it are limited. At the same time, for fatter patients, it is difficult to get in and out after the small table is opened, which is inconvenient to use.

Therefore, there is a need for an infusion chair that can solve the above problems and improve the comfort level of patients during infusion.

It is both practical and space-saving. This multifunctional infusion chair is not only fully functional, but also user-friendly in design, providing great convenience and comfort for infusion patients and accompanying personnel.

As shown in Figures 1, 2 and 15, the seat body 1 includes a seat back 101, a seat cushion 102, a left armrest 103 and a right armrest 104. The left armrest 103 and the right armrest 104 are connected together by two plates spaced apart from each other. The upper plate is named the seat cushion mounting plate 45. The seat cushion 102 is fixed to the seat cushion mounting plate 45 by screws through a first linear slide rail pair 48. The lower plate is named the bottom plate 106. A hollow chamber is formed between the seat cushion mounting plate 45 and the bottom plate 106. This chamber is named the auxiliary seat bench mounting chamber 105. The auxiliary seat bench 7 can be stored in the auxiliary seat bench mounting chamber 105.

The seat back 101 is rectangular as a whole, and its two side surfaces are respectively connected to the inner side surfaces of the left armrest 103 and the right armrest 104 through the seat back adjustment assembly 4. The seat back 101 as a whole can rotate relative to the left armrest 103 and the right armrest 104 along the connection.

In order to improve the patient's comfort, the interior of the chair back 101 is filled with three layers of sponge, of which the outermost layer in contact with the patient is low-density sponge, and the innermost layer is high-density sponge. The high-density sponge is fixed on the back panel supporting the structure of the chair back 101. The middle layer is medium-density sponge. The surface of the chair back 101 is an arc that fits the curve of the human back, which is convenient for patients to sit for a long time. In addition, in order to facilitate the cleaning and disinfection of the infusion chair, a layer of waterproof imitation leather jacket is covered on the outside of the chair back 101.

In order to facilitate the movement of the infusion chair as a whole, a moving wheel 110 is fixed next to each chair leg 109. The main function of the moving wheel 110 is to facilitate the movement of the infusion chair. It is preferred to use an existing universal wheel. When the chair legs 109 are retracted to the left armrest 103 and the right armrest 104, the moving wheel 110 contacts the ground, which can push the infusion chair to move as a whole. When the movement is completed, the chair legs 109 are extended by adjusting the toggle button 83 to lift the infusion chair. The contact between the moving wheel 110 and the ground can be released to place the infusion chair stably on the ground.

The push rod 46 is preferably an existing gas spring that can be locked and adjusted. It is an existing device and can be purchased and used directly.

To facilitate the installation of the table top assembly 6, a rectangular cavity is provided on the right armrest 104, perpendicular to the inner recess of the right armrest 104, and this cavity is named the table top mounting cavity 115. The table top assembly 6 is installed in the table top mounting cavity 115, and in order to avoid interfering with the table top mounting cavity 115 and making way for the retractable chair legs 109, the table top assembly 6 stored in the table top mounting cavity 115 does not affect the extension and retraction of the chair legs 109. At the same time, to facilitate the installation of the infusion pole 3, an installation position for the infusion pole mounting sleeve 305 is reserved on the right armrest 104. In addition, in order to close the table top mounting cavity 115, a foldable mounting cavity cover 116 is fixed to the right armrest 104 by hinges. After the mounting cavity cover 116 closes the table top mounting cavity 115, the surface of the mounting cavity cover 116 is flush with the surface of the right armrest 104.

Two push rods 46 are hinged between the inner plate 113 and the seat cushion mounting plate 45. The two push rods 46 are controlled to extend and retract through the adjustment knob 83 on the left armrest 103. The push rods 46 can control the inner plate 113 to rotate along the hinge, thereby completing the opening and closing of the auxiliary seat mounting cavity 105.

The other end of the inner plate 113 is inserted into the inner part of the outer plate 112, and the two are fixed with slide rails and slide bars at the insertion point with screws. The slide rails and slide bars mainly play the role of guiding and sliding. They are existing devices and can be purchased and used directly. The inner plate 113 and the outer plate 112 can slide along the slide rails, and then adjust the depth of the inner plate 113 inserted into the outer plate 112. In order to facilitate the adjustment of the depth of the inner plate 113 inserted into the outer plate 112, an electric telescopic rod is hinged between the outer plate 112 and the inner plate 113. The extension and retraction of the electric telescopic rod is controlled by adjusting the lever 83. The electric telescopic rod can adjust the depth of the inner plate 113 inserted into the outer plate 112, and then adjust the length of the leg support plate 111, so that the patient can put his legs on the leg support plate 111, thereby improving the comfort of the user. In addition, in order to further improve the comfort, soft pads can be fixed on the inner plate 113 and the outer plate 112 at the contact with the user.

In order to facilitate the placement of the auxiliary stool 7 into the auxiliary stool installation cavity 105, two smooth guide strips 107 are fixed with screws on the inner side of the bottom plate 106, and multiple guide wheels 108 are fixed on the smooth guide strips 107 with installation shafts.

The infusion pole mounting sleeve 305 is embedded in the right handrail 104 and distributed in the height direction of the right handrail 104. The limit box 306 is fixed to the infusion pole 3 by screws. The infusion pole 3 is detachably inserted in the infusion pole mounting sleeve 305, and the depth of the infusion pole 3 in the infusion pole mounting sleeve 305 is adjustable.

The infusion pole 3 is a round stainless steel hollow tube. The main function of the infusion pole 3 is to hang the infusion bottle. A bracket for hanging the infusion bottle is fixed to one end of the infusion pole 3, and an expandable and retractable support leg 303 is screwed to the other end. The main function of the support leg 303 is support. During the infusion process, when the patient leaves the infusion chair (for example, to go to the bathroom), it is extremely inconvenient for the patient to hold the infusion pole 3 with one hand. At this time, the support leg 303 can be unfolded and the infusion pole 3 can be placed on the ground as a whole, which is convenient to use.

In order to facilitate the connection between the support leg 303 and the infusion pole 3 and ensure that the infusion pole 3 has a certain stability after standing, the support legs 303 have three legs, which are evenly hinged on the support leg mounting platform 301 and screwed to the infusion pole 3 through a support leg mounting platform 301.

The support leg mounting platform 301 is a cylindrical plastic platform with an external thread at one end of the support leg mounting platform 301. The support leg mounting platform 301 can be screwed onto one end of the infusion pole 3 through threads. There are three hinged platforms at the other end of the support leg mounting platform 301. Three support legs 303 are hinged to the support leg mounting platform 301 through the hinged platforms. Each support leg 303 can be unfolded 60° relative to the support leg mounting platform 301. In order to avoid position interference and facilitate the installation of the infusion pole 3, the largest size of the support leg mounting platform 301 is the same as the outer diameter of the infusion pole 3.

The cross-section of the support legs 303 is annular, and the three support legs 303 can be spliced into a circular ring. In order to facilitate the deployment of the support legs 303 and the stability after being folded, magnets 304 are fixed on both sides of the three support legs 303. The folded support legs 303 can be tightly adsorbed together under the action of the magnets 304 to prevent unplanned deployment.

The infusion pole mounting sleeve 305 is a metal tube whose cross section is composed of a circle and a rectangle. The outer diameter of the infusion pole 3 is the same as the inner diameter of the circular part of the infusion pole mounting sleeve 305. The infusion pole 3 can be inserted into the circular cross-sectional part of the infusion pole mounting sleeve 305. The limit box 306 on the infusion pole 3 can be inserted into the rectangular cross-sectional part of the infusion pole mounting sleeve 305. A plurality of limit openings 308 penetrating the infusion pole mounting sleeve 305 are provided on both sides of the rectangular part of the infusion pole mounting sleeve 305. The limit openings 308 have a rectangular cross-sectional shape. A plurality of limit openings 308 are provided at intervals on the infusion pole mounting sleeve 305. The depth of the infusion pole 3 inserted into the infusion pole mounting sleeve 305, the height of the infusion pole 3 can be adjusted, or the infusion pole 3 can be disassembled by adjusting the limit block 309 in the limit box 306 and the limit opening 308.

The limit box 306 includes a limit block 309, a pull block 311 and a slide 310 inserted in the limit box 306. The limit box 306 is a rectangular hollow plastic box, which is mainly used as a carrier for installing the limit block 309, the pull block 311 and the slide 310. The cross-sectional size of the limit box 306 is the same as the size of the rectangular part in the cross-sectional area of the infusion pole mounting sleeve 305. The limit box 306 can slide in the infusion pole mounting sleeve 305 along with the infusion pole 3. Two groups of rectangular holes penetrate the limit box 306, and the limit block 309 is inserted into the rectangular holes in the limit box 306, and one end is exposed in the rectangular hole, which cooperates with the limit opening 308 on the infusion pole mounting sleeve 305 for limiting. The length of the limit block 309 extending out of the limit box 306 can be adjusted through the slide 310, and the cooperation between the limit block 309 and the limit opening 308 can be adjusted, thereby adjusting the position of the infusion pole 3 in the infusion pole mounting sleeve 305, and completing the height adjustment and disassembly of the infusion pole 3.

The limit block 309 is a rectangular metal block, and the cross-sectional size of the limit block 309 is the same as the size of the limit opening 308. In order to facilitate the control of the extension and retraction of the limit block 309, two pull blocks 311 are fixed opposite to each other on one end of the limit block 309 inserted in the limit box 306. The pull block 311 is a rectangular metal block welded on the side of the limit block 309, and the two pull blocks 311 are distributed opposite to each other on the limit block 309. In order to control the limit block 309 to retract into the limit box 306 by the pull block 311, a pull groove 315 is provided on the surface of the pull block 311 perpendicular to the inner recess of the pull block 311. The angle between the pull groove 315 and the side of the pull block 311 is 60°, and the pull groove 315 is provided on the planes where the two pull blocks 311 point opposite to each other.

The slide 310 used to drive the pulling block 311 to move is stuck in the pulling groove 315. The function of the slide 310 is mainly to cooperate with the pulling groove 315 to drive the pulling block 311 to move. The upper pulling slide 310 can drive the pulling block 311 to move. In order to make the limit block 309 move linearly under the action of the slide 310, a slide bar is fixed with screws on the opposite surface of the pulling block 311 with the pulling groove 315. At the same time, a slide groove is opened at the corresponding position of the inner side surface of the limit box 306. The slide bar cooperates with the slide groove. In this way, when the slide 310 drives the pulling block 311 to move, the pulling block 311 can move along the slide groove, and then most of the limit block 309 is retracted into the limit box 306, and the cooperation between the limit block 309 and the limit opening 308 is released, so as to adjust and disassemble the infusion rod 3.

In order to facilitate the reset of the limit block 309 that has been retracted into the limit box 306 and to re-match the limit block 309 with the limit opening 308, a return spring 312 is placed in the limit box 306, one end of the return spring 312 is against the limit block 309, and the other end is in contact with the baffle fixed in the limit box 306. When the limit block 309 is retracted into the limit box 306, the return spring 312 is compressed. When the force applied by the slide 310 to the pull block 311 is released, the limit block 309 extends out from the limit box 306 under the action of the return spring 312 and matches with the limit opening 308. At the same time, the slide 310 is reset under the reaction force of the pull groove 315.

In order to facilitate the control of the movement of the slide 310, a pulley 314 is installed at the upper end of the limit box 306, and a travel distance for the slide 310 to move is reserved between the pulley 314 and the slide 310. A pull rope 313 is fixed to the upper end of the slide 310, and the other end of the pull rope 313 passes around the pulley 314 and passes into the infusion pole 3.

In order to facilitate the control of the pull rope 313, two pulleys 314 are fixed at intervals in the infusion pole 3 with an installation axis, and the pulleys 314 can rotate freely along the installation axis. One of the pulleys 314 is horizontally divided from the pulley 314 in the limit box 306. The pull rope 313 passes through the infusion pole 3 and first wraps around this pulley 314 for turning. The other pulley 314 is fixed 50 cm above this pulley 314, and on the infusion pole 3, an unlocking handshake 307 is horizontally hinged to the upper pulley 314. The unlocking handshake 307 is hinged to the infusion pole 3, and the unlocking handshake 307 can rotate along the hinge. The pull rope 313 passing through the infusion pole 3 successively bypasses the lower and upper pulleys 314 and then passes through the infusion pole 3 and is connected to the unlocking handshake 307. Pressing the unlocking handshake 307 can tighten the pull rope 313, thereby driving the slide 310 to move upward.

In order to ensure the stability of the cooperation between the pull rope 313 and the pulley 314, the pulley 314 is treated to prevent it from falling off. At the same time, a compression spring is fixed to the non-hinged end of the unlocking handshake 307. One end of the compression spring is in contact with the unlocking handshake 307, and the other end is in contact with the outer wall of the infusion pole 3. When the unlocking handshake 307 is pressed, the compression spring is compressed. After the unlocking handshake 307 is released, the unlocking handshake 307 is reset under the action of the compression spring.

Definition: In this embodiment, the ground is used as a reference, the direction from the infusion chair to the ground is downward, and the direction from the ground to the infusion chair is upward.

Regarding the adjustment and disassembly of the infusion pole 3: when the height of the infusion pole 3 needs to be adjusted, first hold the unlocking handle 307 tightly, at this time the pull rope 313 is tightened, and when the pull rope 313 is tightened, the slide 310 is driven to move upward, and while the slide 310 moves upward, the pull block 311 matched with the slide 310 moves horizontally along the slide slot under the action of the slide 310, and then drives the limit block 309 connected to the pull block 311 to move, and pull the limit block 309 into the limit box 306, at this time the limit block 309 is moved out of the limit opening 308, and the return spring 312 is stressed, and at this time the infusion pole 3 can be moved to adjust the height and pulled out;

After the infusion pole 3 is moved to a suitable height, the unlocking handle 307 is released, at which time the pull rope 313 is loosened, the limit block 309 is reset under the action of the reset spring 312, the limit block 309 is reinserted into the limit opening 308, and at the same time the slide 310 is moved down and reset, thus completing the fixing of the position of the infusion pole 3;

When the patient needs to leave the infusion chair and the infusion pole 3 is pulled out, the three support legs 303 on the infusion pole 3 are unfolded by hand. After the support legs 303 are unfolded, the infusion pole 3 can be stably placed on the ground to avoid the patient holding it. When the infusion pole 3 needs to be reinstalled on the infusion chair, the support legs 303 must be folded up first. The folded support legs 303 are adsorbed together by the magnets 304 fixed on their sides. Because the diameter of the folded support legs 303 is not larger than the outer diameter of the infusion pole 3, the infusion pole 3 together with the support legs 303 can be inserted into the infusion pole installation sleeve 305 to complete the installation of the infusion pole 3.

As shown in FIGS. 1 , 11 , 12 and 15 , the liquid medicine monitoring assembly 5 includes a monitoring box 51 and a laser monitoring head 54 . The laser monitoring head 54 is fixed in the monitoring box 51 with glue, and the monitoring box 51 is fixed to the right armrest 104 through a mounting rod.

The monitoring box 51 is a plastic box with a rectangular cross-section. Its main function is to serve as a carrier for installing the laser monitoring head 54 and other components. Two mutually perpendicular grooves are provided on the surface of the monitoring box 51 perpendicular to the vertical and horizontal directions of the monitoring box 51. The horizontal rectangular groove is a functional groove 55, and the longitudinal arc groove is a catheter groove 52. The infusion catheter can be placed in the catheter groove 52, and after being placed in the catheter groove 52, it will not fall off from the catheter groove 52 without external force.

The laser monitoring head 54 for monitoring whether there is any medicine in the infusion catheter is installed in the catheter groove 52 and points to the infusion catheter. The change in the laser refractive index of the laser monitoring head 54 when there is medicine in the infusion catheter determines whether the medicine in the infusion catheter has been dripped out. After the medicine has been dripped out, the buzzer and indicator light in the monitoring box 51 will light up red (the buzzer and indicator light are existing technologies and are not drawn in the figure).

In winter, in order to improve the patient's comfort and prevent the patient from getting cold during infusion, a heating block 53 is fixed on the inner side of the catheter groove 52. The control panel 81 in the control unit 8 can adjust the switch and heating temperature of the heating block 53 to heat the medicine.

After the medicine in the infusion catheter is infused, in order to prevent the patient or medical staff from failing to close the infusion catheter in time to cause blood backflow or local tissue swelling of the patient, a clamping assembly for clamping the infusion catheter is fixed in the function slot 55, and the clamping assembly includes a screw motor 56, a fixed clamping block 58 and a movable clamping block 59. The screw motor 56 is installed in the function slot 55, and the fixed clamping block 58 and the movable clamping block 59 are distributed on both sides of the catheter slot 52, wherein the fixed clamping block 58 is fixedly connected to the monitoring box 51 by screws, and the movable clamping block 59 is installed on the screw motor 56 by a flange nut. The movable clamping block 59 can be controlled by the screw motor 56 to move closer to or away from the fixed clamping block 58, and the fixed clamping block 58 and the movable clamping block 59 clamp the infusion catheter between the fixed clamping block 58 and the movable clamping block 59, so that the infusion catheter stops infusing, effectively preventing blood backflow or swelling of the patient's hand.

The fixed clamp block 58 is a plastic block with a sideways “T”-shaped cross section. The fixed clamp block 58 is fixed to the upper and lower sides of the functional slot 55 by screws and is closer to the outside than the screw motor 56 .

The movable clamping block 59 is the same as the fixed clamping block 58, both of which are plastic blocks with a "T"-shaped cross-section placed on the side. The difference from the fixed clamping block 58 is that one end of the movable clamping block 59 is fixed with a flange nut that cooperates with the screw on the screw motor 56 by a screw. The movable clamping block 59 cooperates with the screw on the screw motor 56 through the flange nut. The movable clamping block 59 can move with the rotation of the screw motor 56. In order to ensure that the movable clamping block 59 moves stably in a straight line along the screw motor 56, a guide rod 57 is fixed in the functional groove 55 parallel to the screw motor 56. The guide rod 57 passes through the movable clamping block 59. Under the action of the screw motor 56 and the guide rod 57, the movable clamping block 59 can make a straight line movement along the guide rod 57, adjust the distance between it and the fixed clamping block 58, and complete the clamping and release of the infusion catheter.

In order to improve the aesthetics and prevent debris from falling into the functional groove 55 and affecting the normal movement of the screw motor 56 and the movable clamping block 59, a cover plate that can close the functional groove 55 is fixed to the monitoring box 51 with screws. The disassembly and assembly of the cover plate does not affect the movement of the movable clamping block 59 along the guide rod 57.

As shown in FIGS. 1 , 2 , 13 , 14 and 15 , in order to facilitate the patient to use and place personal belongings, a table board assembly 6 is also installed in the chair body 1 , and the table board assembly 6 can be stored in the table board installation cavity 115 on the right armrest 104 .

The table top assembly 6 includes a table top 61, a table top mounting frame 62 and a sliding mounting frame 63. The table top mounting frame 62 is a metal mounting frame with an "L"-shaped cross-section. A hinge joint is welded at the end of the shorter vertical arm of the table top mounting frame 62, which can be hinged to the hinge seat in the table top mounting cavity 115 through the hinge joint, so that one end of the table top mounting frame 62 is fixed in the table top mounting cavity 115. The table top 61 is hinged to the sliding mounting frame 63, and the sliding mounting frame 63 is connected to the table top mounting frame 62 through a second linear slide rail pair 64. The sliding mounting frame 63 can move linearly along the table top mounting frame 62 under the action of the second linear slide rail pair 64.

The sliding mounting frame 63 is a metal frame with an "L"-shaped cross-section. The table top 61 is hinged on the shorter vertical plate on the sliding mounting frame 63. The 90° range formed by the two vertically distributed vertical plates on the sliding mounting frame 63 is the folding range of the table top 61. When the table top assembly 6 is stored in the table top mounting cavity 115, the table top 61 flips 90° and contacts the narrower plate surface of the sliding mounting frame 63. When the table top 61 needs to be used, the table top 61 is unfolded and contacts the wider plate surface of the sliding mounting frame 63.

When the table top 61 is unfolded, in order to facilitate the user to enter and exit and to adjust the distance between the table top 61 and the user, a second linear slide rail pair 64 is fixed between the sliding mounting frame 63 and the table top mounting frame 62 with screws. The slide rail in the second linear slide rail pair 64 is fixed on the table top mounting frame 62, and the slide rail is flush with the table top mounting frame 62 in the length direction. The slider in the second linear slide rail pair 64 is fixed on the sliding mounting frame 63. Pushing the table top 61 can drive the sliding mounting frame 63 to move along the slide rail in the second linear slide rail pair 64, thereby adjusting the distance between the table top 61 and the user.

In order to facilitate the removal of the table top assembly 6 from the table top mounting cavity 115, a rectangular table top pull ring 65 is fixed to the non-hinged end of the table top mounting frame 62. The table top assembly 6 can be removed from the table top mounting cavity 115 by pulling the table top pull ring 65.

As shown in Figures 1, 2, 3 and 15, in order to improve the comfort of the user, a temperature adjustment part 2 is also installed in the seat body 1. The temperature adjustment part 2 includes a heating component 21 for heating the seat back 101 and the seat cushion 102 in winter and a heat dissipation component 22 for dissipating heat to the user in summer.

The heating assembly 21 includes multiple groups of heating wires 23 embedded in the chair back 101 and the seat cushion 102. The heating wires 23 are embedded in the medium-density sponge in the middle layer. The heating temperature of the heating wires 23 can be adjusted through the control screen 81 in the control unit 8. In order to improve patient comfort and ensure safety and energy saving, the heating temperature of the heating wires 23 is preferably 0-37°C.

The heat dissipation assembly 22 includes a heat dissipation fan 24 and a rectangular fan mounting cover 25. The fan mounting cover 25 is fixed to the inner side surfaces of the left armrest 103 and the right armrest 104 by screws and points toward the user. The heat dissipation fan 24 is installed in the fan mounting cover 25, and preferably three heat dissipation fans 24 are installed in each fan mounting cover 25. At the same time, in order to facilitate air circulation, heat dissipation holes are opened on the fan mounting cover 25. When the heat dissipation fan 24 rotates, air can flow through the heat dissipation holes to achieve fanning, sweat removal and heat dissipation. In addition, the number of switches and wind force of the heat dissipation fan 24 can be adjusted through the control panel 81 in the control unit 8.

In addition, regarding the overall power supply of the infusion chair, the infusion chair can be connected to an external power supply through a plug, or a power supply can be built into the infusion chair and the power supply can be charged through an external plug to complete the power supply. Both of these power supply methods are existing mature technologies and will not be elaborated here.

As shown in FIGS. 1 , 2 and 15 , in order to facilitate the accompanying personnel to sit and avoid the accompanying personnel occupying the infusion chair, an auxiliary bench 7 is placed in the auxiliary bench installation cavity 105 on the chair body 1 .

The auxiliary bench 7 is a bench with adjustable height. A handle 71 is fixed on the side of the auxiliary bench 7. The auxiliary bench 7 placed in the auxiliary bench installation cavity 105 can be taken out by pulling the handle 71. At the same time, in order to avoid the loss of the auxiliary bench 7 due to arbitrary movement, a fixed pull rope can be optionally installed in the auxiliary bench installation cavity 105, one end of the fixed pull rope is fixed in the auxiliary bench installation cavity 105 and the other end is fixed on the auxiliary bench 7.

The infusion chair of the present invention has the following functions and advantages:

1. The temperature is adjustable. The heating component 21 and the heat dissipation component 22 in the temperature adjustment part 2 can heat the seat in winter and blow air to the user in summer, thereby improving the comfort of use.

2. It has the ability to monitor the drug solution and lock the infusion catheter after the drug solution has dripped. During the infusion process, the laser monitoring head 54 in the drug solution monitoring component 5 is used to monitor whether the drug solution has dripped. After the drug solution has dripped, the buzzer sounds a reminder, the indicator light turns red, and the movable clamp block 59 set in the monitoring box 51 moves to cooperate with the fixed clamp block 58 to clamp the infusion catheter to prevent blood return and tissue swelling in the patient's hand.

3. Easy to move and fix. The moving wheels 110 arranged on the left armrest 103 and the right armrest 104 can push the infusion chair to move as a whole and change its position. When the position is adjusted, the seat body 1 is lifted as a whole by extending the retractable chair legs 109 arranged on the left armrest 103 and the right armrest 104 to release the contact between the moving wheels 110 and the ground, which facilitates the movement of the infusion chair while ensuring the stability of the infusion chair when it is not moving.

4. A special seat for the accompanying person is designed. The auxiliary bench 7 that can be stored in the auxiliary bench installation cavity 105 is provided for the accompanying person to sit on. It is convenient to use and avoids the accompanying person occupying the infusion chair. At the same time, after the auxiliary bench 7 is stored in the auxiliary bench installation cavity 105, the opening of the auxiliary bench installation cavity 105 is closed by the leg support plate 111, which effectively prevents the auxiliary bench 7 placed in the auxiliary bench installation cavity 105 from falling when the infusion chair is transported and moved.

5. The height of the infusion pole 3 can be adjusted with one hand, and after the infusion pole 3 is removed from the infusion chair, the infusion pole 3 can stand on the ground by itself using the supporting legs 303 on the infusion pole 3, avoiding the patient's continuous holding of the infusion pole, which is convenient to use.

6. A table board assembly 6 is provided in the right armrest 104, and the patient's belongings are placed on the table board 61 in the table board assembly 6, which is convenient to use and avoids clutter on the ground. In addition, the interval between the table board 61 and the patient can be adjusted by the second linear slide rail pair 64 provided between the table board mounting frame 62 and the sliding mounting frame 63. When the patient needs to get out of the infusion chair, the distance between the table board 61 and the patient can be increased by pushing the table board 61, so that the patient can get in and out conveniently.

7. The angles of the chair back 101, the seat cushion 102 and the leg support plate 111 are adjustable. By synchronously adjusting the chair back 101 and the seat cushion 102, the patient's sitting posture can be improved and the patient's comfort can be improved. The leg support plate 111 can be used to place the patient's feet. At the same time, by adjusting the angle of the leg support plate 111, numbness and discomfort in the legs after sitting for a long time can be avoided, thereby improving the patient's comfort.

Regarding the adjustment process of the chair back 101, the seat cushion 102 and the leg support plate 111:

When the chair back 101 and the seat cushion 102 need to be adjusted, the adjustment knob 83 connected to the push rod 46 in the adjustment component mounting box 41 on the left armrest 103 is manually turned, and the body lies back to apply pressure to the chair back 101. At this time, the gear 43 rotates, driving the rack 42 to move, and the push rod 46 connected to the rack 42 is compressed. When the gear 43 rotates, the chair back 101 also rotates (in order to prevent the gear 43 from falling off the rack 42, the range of movement of the rack 42 is greater than the angle adjustment range of the chair back 101). When the angle is adjusted to a suitable position, the adjustment knob 83 is released. At this time, the adjustment of the chair back 101 is completed. Because the slider set on the seat cushion 102 is connected to the rack 42 through the synchronous frame 49, the seat cushion 102 also moves when the angle of the chair back 101 is adjusted, thereby improving the patient's comfort. When it is necessary to adjust it back, turn the adjustment knob 83 (at this time, the patient is not in contact with the chair back 101), and the automatic push rod 46 is reset to push the rack 42 to move, thereby completing the reset of the angle of the chair back 101.

When the patient needs to raise his legs to relieve leg discomfort or take out the auxiliary stool 7, he can manually turn the adjustment knob 83 on the left armrest 103 connected to the push rod 46 on the leg support plate 111. At this time, the push rod 46 pushes the leg support plate 111 to open along the hinge. At this time, the patient can put his legs on the leg support plate 111 and take out the auxiliary stool 7. In order to improve the comfort, the adjustment knob 83 connected to the electric telescopic rod on the leg support plate 111 can be used to control the outer plate 112 and the inner plate 112 of the leg support plate 111. 3, which is convenient for patients of different heights to place their legs. When the leg support plate 111 needs to be retracted, the outer plate 112 and the inner plate 113 must be folded up first, and then the adjustment button 83 connected to the push rod 46 on the leg support plate 111 is pressed to apply a force to the leg support plate 111 to push the leg support plate 111 back. At this time, the push rod 46 connected to the leg support plate 111 is compressed to store energy for the next opening of the leg support plate 111, so that the leg support plate 111 can be automatically opened when the adjustment button 83 is pushed.

The above embodiments are only for illustrating the technical idea of the present invention, and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
