JP2009028478A - Cart for body traction type intravenous drip and for oxygen cylinder for both of indoor or outdoor application - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a cart for both of indoor and outdoor applications which is loaded with an intravenous medicine container or an oxygen cylinder, fixed on the waist of a patient by an attached belt, and towed by the body without using hands. <P>SOLUTION: This cart for both of indoor and outdoor applications is formed into a structure wherein one unit can be used in a hospital room, a hospital ward, and on the outside of the hospital ward by simple operations of an easy vertical motion of the front leg from front and rear legs on which a wheel is attached, and the attaching/detaching of the attached belt only. When the attached belt is tied, and the front leg is lifted, the patient can freely walk even on the outside of the hospital ward. Since the cart is towed by the body, a handle function is not required, and both hands are free. Also, since the own cart does not enter his visual field, a feeling of restraint is little. In addition, since the cart is for both of indoor and outdoor, the hospital side can reduce equipment investments and possessed spaces as well. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention is a towable cart with a body that allows a patient to freely walk around in the hospital ward, inside the ward, or outside the ward while the patient receives infusion or oxygen inhalation, and without using a hand. .

Conventionally, there is an infusion stand with casters attached so that a patient can walk in a hospital room or ward even during infusion. In addition, there is an item that can be additionally equipped with a drip stick on a walking car in which a patient can walk while pushing inside a hospital or medical facility with his / her hand or upper body. In addition, there is a device that attaches a drip-powder hanging bracket directly to a patient's upper body with a belt or the like so that the patient can go outside during the drip. In addition, there is an oxygen cylinder cart in which a patient pulls with one hand for walking while inhaling oxygen.
We are not aware of whether or not there is a patent application related to the above prior art property and the existence of patent documents.

  However, the existing drip stand is not supposed to be used outside the ward because drip is the main function, and conversely, the existing walking car is mainly used for assisting walking, so it is not used in hospital rooms as a drip. Not assumed. In addition, in the case of a device that attaches the drop drop hanging bracket directly to the patient's upper body, there is no problem in moving outside, but in addition to the weight of the attachment device itself, the weight of the drop drop is not healthy. The patient receives directly and the load on the patient is large. In addition, since it is impossible to lie down on the bed in the hospital room with the equipment attached, the equipment needs to be attached and detached each time the bed is moved back and forth, and the infusion is replaced with an infusion stand for the hospital room. Therefore, there is currently no device that allows a patient to walk around the inside of a ward, inside a ward, or outside the ward without exchanging the device or performing the work accompanying it while instilling or inhaling oxygen.

  And since the existing drip stand, walking car, and oxygen cylinder cart are used by the patient pushing and pulling them with their hands and arms, they can walk, but cannot be used by people with some handicap. In addition, there are restrictions on walking while holding an object.

  In order to solve this problem, the invention of claim 1 is such that a drip medicine is placed on the upper part of the main column, and a wheel is attached to each of the three leg-shaped leg ends of the lower part of the main column, and only the front leg can be raised or lowered. Make the structure. When walking in a ward or in a short ward, the front leg can be lowered and used with 3 legs standing alone, or when walking outside the ward or in a relatively long ward, the front leg is raised and used with 2 legs. You can also do things. At that time, adjust the height of the attached belt attached to the center of the main column so that the main column is almost perpendicular to the ground, and fix it to the patient's upper waist and pull it with the body without using hands. . In other words, the patient's body takes on the role of the raised front leg instead, but the cart does not receive the weight of the cart itself or infusions directly, and the cart follows in the direction the patient moves, so the handle function also Unnecessary and open hands. Furthermore, since the contact point between the patient and the cart is an attached belt on the waist, there is no limit to the possibility of the device falling over from the center of gravity. (See Figure 1)

  According to the invention of claim 2, an oxygen cylinder is mounted at the lower part of the main column, and a wheel is attached to each of the four leg-shaped leg ends at the lower part of the main column, and only the front leg among them can be raised and lowered. At home or in the hospital room, the front leg can be lowered and used with four legs standing alone, or when going out or outside the ward, the front leg can be raised and used with two legs. At that time, the height of the attached belt attached to the upper part of the main shaft is adjusted so that the main pillar is almost perpendicular to the ground, and it is fixed on the patient's upper waist and pulled by the body without using hands. In other words, the patient's body takes on the role of the raised front leg instead, but the patient does not receive the weight of the cart itself or oxygen cylinder directly, and the cart follows the direction the patient moves, so the handle function is also provided Unnecessary and open hands. Furthermore, since the contact point between the patient and the cart is an attached belt on the waist, there is no limit to the possibility of the device falling over from the center of gravity. (See Figure 5)

  The invention of claim 3 is provided with an instillation drug at the upper part of the main column and an oxygen cylinder at the lower part of the main column, and a wheel is attached to the tip of each of the four legs at the lower part of the main column. The structure can be raised and lowered. When walking in a ward or in a short ward, the front leg can be lowered and used with 4 legs, or when walking out of a ward or walking in a relatively long ward, the front leg is raised and used as two legs. You can also do things. At that time, adjust the height of the attached belt attached to the center of the main column so that the main column is almost perpendicular to the ground, and fix it to the patient's upper waist and pull it with the body without using hands. . In other words, the patient's body takes on the role of the raised front leg instead, but the cart will follow the patient's direction of travel without the patient directly receiving the weight of the cart itself, infusions, or oxygen cylinders. Handle function is unnecessary and both hands are free. Furthermore, since the contact point between the patient and the cart is an attached belt on the waist, there is no limit to the possibility of the device falling over from the center of gravity. (See Figure 7)

  Furthermore, invention of Claim 4 is an apparatus which suppresses that the drip medicine container hung on the drip stand at the time of walking while drip is shaken by the vibration during movement. A pair of left and right arm clampers that are attached to the top of the main pole, just below the hook for the instillation. In order to be compatible with all types of dripping containers, such as plastic bag type, bottle type, and bottle type, the structure is such that the dripping container is fixed with an arm. (See Figure 9)

  Even if the patient is instilling or inhaling oxygen, simply raise and lower the front leg of this cart and remove the attached belt. The promenade can be walked freely. In addition, because it is a structure that can be used as a single unit inside the ward, inside the ward, and outside the ward, each time it is used, it is possible to replace drip pills when switching equipment for indoor / outdoor use, drip / walking assistance, oxygen, etc. There is no troublesome work such as replacing cylinders, so there is no need to receive help from nurses. Moreover, since the cart does not directly enter your field of view, stress such as restraint and restraint on the cart is unlikely to occur. On the other hand, since the hospital is also a dual-use type, the capital investment can be reduced, and further, the effect of reducing the floor area for possessing many appliances including these can be produced.

  Furthermore, since it is a moving system that is attached to the upper waist of the patient with an attached belt and pulled by the body, both hands are free. This allows patients to walk while holding canes, books, drinks, umbrellas, etc. in their hands. It can also be used by patients who have leg problems and need crutches in both hands. In addition, even if the front legs are raised and lowered and the attached belt is attached or detached, even people with some inconvenience in their hands can use it. In the present invention, many hospitalized patients who have been forced to live in hospitals that have been virtually confined to bed for drip and oxygen inhalation, for hospitals who recommend early walking and rehabilitation for fast recovery Gains the freedom to undergo light rehabilitation, take a walk outside the ward or sunbathe, even during infusions or while receiving oxygen.

FIG. 2 shows an embodiment of claim 1. The figure is the perspective view which looked at the state which lowered the front leg from back.

When the front leg 1 is lowered, the front leg lower stopper 5 is held by the front leg lower stopper receiver 6, and when it is raised, the front leg upper stopper 3 is held by the front leg upper stopper receiver 4. When the front leg 1 is raised, the front wheel 2 is not in contact with the ground, and only the rear wheel 10 is in contact with the ground. Further, an oxygen cylinder receiver 21 is fixed to an oxygen cylinder receiver arm 22 in the middle of the main column 18 , and the oxygen cylinder is structured to be loaded and unloaded later. In the upper part of the main pillar 18 , a back 15 and a belt 16 absorb a small change in the height of the waist accompanying walking of the patient, and a joint 14 that adjusts the inclination of the main pillar when going up and down the hill. It is connected to a belt height adjuster 13 . The height is adjusted so that the main column 18 is approximately perpendicular to the ground in accordance with the position of the patient's waist, and is fixed by the belt height adjustment knob 17. This height adjustment only needs to be performed once at the beginning. . 2 Assisi Since the place of the legs 1 before the raised the patient's body, the handle function to Cart unnecessary, and since linked at the position of the waist possibility of even carts tipping centroid manner is very low. The belt 16 is preferably a tape adjuster buckle belt so that it can be easily attached and detached. Further, the rear wheel 10 preferably has a wheel diameter approximately 1.5 to 2 times larger than that of the front wheel 2 in consideration of outdoor running on uneven ground.

FIG. 8 shows an embodiment of claim 3. The figure is the perspective view which looked at the state which lowered the front leg from back. When using with two legs, the patient stands with his back in front of the cart, and the backrest 15 is placed on the waist and the buckle of the belt 16 is closed and fixed. Next, when the left and right front leg up / down levers 12 are grasped with both hands and pulled forward as indicated by the dotted arrow in the figure, the front leg 1 is raised with the axis 7 as the rotation axis by the movement shown by the solid arrow in the figure. To lower it, grab the front leg up / down lever 12 and pull it backward. When the front leg 1 is lowered, the front leg lower stopper 5 is held by the front leg lower stopper receiver 6, and when it is raised, the front leg upper stopper 3 is held by the front leg upper stopper receiver 4. When the front leg 1 is raised, the front wheel 2 is not in contact with the ground, and only the rear wheel 10 is in contact with the ground. Further, an oxygen cylinder receiver 21 is fixed to the oxygen cylinder receiver arm 22 at the lowermost part of the main pillar 18 , and the oxygen cylinder is structured to be loaded and unloaded later. Further, in the middle of the main column 18 , the back 15 and the belt 16 absorb a small change in the height of the waist accompanying the walking of the patient, and the joint 14 adjusts the inclination of the main column when going up and down the hill. It is connected to a belt height adjuster 13 . The height is adjusted so that the main column 18 is approximately perpendicular to the ground according to the position of the patient's waist, and is fixed with the belt height adjustment knob 17. Good. 2 Assisi Since the place of the legs 1 before the raised the patient's body, the handle function to Cart unnecessary, and since linked at the position of the waist possibility of even carts tipping centroid manner is very low. The belt 16 is preferably a tape adjuster buckle belt so that it can be easily attached and detached. Further, the rear wheel 10 preferably has a wheel diameter approximately 1.5 to 2 times larger than that of the front wheel 2 in consideration of outdoor running on uneven ground.

FIG. 10 shows an embodiment of claim 4. A pair of left and right arm clampers 32 is attached under the hook 24 at the top of the main pole 23. Figure left of the main pole 23 is in the closed state of the arm clamper 32, with the sub-arm axis a 26 pulls in the direction of the solid arrow in the figure to open. Even when the arm clamper 32 is completely closed, the main arm axis 28 and the sub arm axis a 26 come into contact with each other, so the four arms 25 are not in close contact with each other. Therefore, the flow of the chemical solution in the plastic bag type container is not blocked. The right side is a state where the arm clamper 32 is opened to the maximum. Coil springs are housed in the main arm axis 28 , sub arm axis a 26 , and sub arm axis b 27 , respectively, and force is always acting in the direction of the dotted line arrow in the figure. It is a structure to do. The left and right arm clampers 32 can be adjusted in height by moving the slider 29 up and down on the main pole 23 and are fixed in position by the slider fixing knob 30. Drip containers are broadly divided into bottle types and plastic bag types, but they vary in type and size. However, this structure enables all correspondence. Thereby, the movement of the infusion medicine container that has been shaken during the movement can be firmly suppressed.
