DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a gantry rack used for mounting an infusion container at a medical site such as an operating room, and the technical field of a power supply device for medical electrical equipment.

[0002]

2. Description of the Related Art Conventionally, this kind of gert rack is configured so that an infusion container such as a glass bottle, a plastic bottle, and a vinyl bag containing a liquid for infusion can be hung considerably above the position of a patient. I have. According to the garter rack constructed as described above, the infusion can be automatically performed by the action of gravity without occupying a limited effective space around the patient in the operating room or the like, which is convenient.

On the other hand, with the advancement of medical treatment, medical electrical equipment having a 3P (pin) plug with a ground electrode has been generally used in order to prevent electric shock to a patient. 3P with grounding pole for various reasons and lack of recognition
In many cases, outlets are not widespread. In this case, the 3P plug of the medical electrical equipment is connected to the existing 2P without ground electrode.
The medical electrical equipment is used by connecting the (pin) outlet with the grounding electrode floated, but the safety cannot be maintained with this. Therefore, there has been proposed a medical safety power supply device using an insulating transformer that receives power supply from a 2P outlet as an input and outputs (supplies power) from a 3P outlet with a ground electrode by a pseudo-ground circuit (Medical Science Vol. 57,
No. 7, 1987, Patent No. 1735759). According to the medical safety power supply device, even in a medical facility having no grounding facility, a medical electrical device having a 3P plug with a grounding electrode can be used in an intended use mode.

[0004]

However, since the center of gravity is first high in the above-mentioned girdle rack, stability when a heavy infusion container is hung is deteriorated. In this case, it is only necessary that a nurse or the like keeps the gurtle rack from falling.However, the presence of a nurse holding the gartle rack in this way is obstructive, especially in the operating room, and the effective space around the patient is not sufficient. It is occupied by necessity, which leads to lower quality of the operation. In addition, there is a problem that the reliability of holding by hand is fundamentally low. Conversely, if the girdle rack is constructed to be heavy and long, such a problem can be solved, but placing such a large tool close to the patient also unnecessarily occupies the effective space around the patient in the operating room. Result. Further, it is not a good idea to consider the difficulty in moving such a heavy and large gartle rack inside the facility.

[0005] On the other hand, the above-mentioned medical safety power supply device necessarily has to be a considerably large and heavy device because it includes an insulating transformer and the like. Placing such a large and heavy device again unnecessarily occupies the available space around the patient and hinders surgery. For this reason, the above-mentioned medical safety power supply device has not been put to practical use.

However, if power is supplied directly to the medical electrical equipment from a 2P outlet or a 3P outlet as a wall outlet provided on a wall of an operating room or the like, it is dangerous because an electric shock is given to a patient due to electric leakage. In particular, at the time of electric leakage or the like in one medical electric device, there is an inconvenience that the power supply of the whole room is turned off because the breaker which is the base of the wall wiring is dropped. Furthermore, when power is supplied from a wall outlet to a plurality of medical electrical devices using a octopus foot wiring as is currently performed in ordinary medical facilities, the power cord is scattered on the floor in the operating room. In addition, there is a problem in that the power cord may come off or be caught on a foot, as well as hindering an operation or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a girdle rack with a power supply device capable of supplying a highly safe and easy-to-use power supply while effectively utilizing a space around a patient receiving an infusion. The task is to provide.

[0008]

According to a first aspect of the present invention, there is provided a girdle rack with a power supply device, wherein the girdle rack has a pole portion which is vertically arranged and which is attached to an upper end of the pole portion. A hanger for hanging an infusion container, and a housing attached to the lower end of the pole,
A power supply device housed in the housing; and a caster on which the housing is mounted. The power supply device receives power through a power cord having a 2P plug connectable to a wall outlet. A transformer having a structure in which a primary side and a secondary side are electrically insulated; a leakage breaker; and a power supply from the secondary side of the transformer via the leakage breaker. A plurality of grounded 3P outlets respectively provided on the outside, and a plurality of grounded 3P outlets;
A protection resistor is provided between each ground electrode of the P outlet and a secondary side of the transformer.

According to the girdle rack with the power supply device according to the first aspect, if the infusion container is first placed on the hanger portion attached to the upper end of the pole portion, the infusion container is arranged higher than the patient. Infusion can be performed using an infusion solution placed in an infusion container. Here, since a relatively heavy power supply device equipped with a transformer and the like is housed in the housing attached to the lower end side of the pole part, the center of gravity of the gartle rack is reduced according to the weight of this power supply device. ,
The stability against falling of the gartle is remarkably improved. Furthermore, since the housing is mounted on the casters, the movement of the relatively heavy girdle rack can be performed without any problem by pushing the pole and the housing by hand.

Then, a power cord having a 2P plug is connected to a 2P outlet having no grounding pole as a wall outlet, and a transformer supplied to the primary side via the power cord connects to the secondary side. 3 with grounding pole connected to
Power is supplied to two pins of the P outlet other than the ground electrode. At the same time, since the secondary side of the transformer having a structure in which the primary side and the secondary side are electrically insulated and the protection resistor function as a pseudo grounding circuit, the grounding of the 3P outlet with the grounding electrode is performed. The poles literally function as ground poles. Therefore, the 3P outlet with the grounding electrode is
If a medical electrical device having a P plug is connected, power can be supplied in the intended use mode, that is, while keeping the medical electrical device in a good grounded state. Since a plurality of such 3P outlets with ground electrodes are provided in the power supply device, if a plurality of medical electrical devices are connected to them, only one power cord from the wall outlet is required. As compared with the case where power is supplied to a plurality of medical electrical devices using the stranded wire, scattering of the power cord to the floor in the operating room can be reduced. Furthermore,
An electric leakage breaker is provided on the secondary side of the transformer. Therefore, even if electric leakage occurs in a medical electric device or the like connected to a 3P outlet, the electric leakage breaker operates to cause a patient or medical electric device to operate. Danger can be reduced.

As described above, even in a medical facility where a 3P outlet with a grounding electrode is not provided as a wall outlet, the patient receives a drip in an operating room or the like, and at the same time, a patient receiving a medical treatment or examination with medical electrical equipment. If a gertle rack with a power supply device is placed, the space around the patient can be effectively used to supply power to a plurality of medical electrical devices with high safety and ease of use while performing infusion. In this case, especially when the power supply is placed in a space where there is almost no use, especially under the conventional gertle rack (on the casters of the gurtle rack), the space in the operating room can be reduced as compared with the case where the power supply is separately placed alone. By using a power supply unit, including this transformer, which is basically quite heavy under the poles of the gantry rack, this weight can be used to improve the stability of the gantle rack against overturning. It is very efficient because it is used for

According to the girdle frame with the power supply device according to the first aspect, even if the resistance element is destroyed due to a device failure, aging, or any other unpredictable reason, both of the resistance elements having different materials are used. Are almost never destroyed at the same time. Since these resistance elements are connected in parallel, the minimum function of the protection resistor is maintained by the remaining one resistance element even if one of the resistance elements is destroyed. Therefore, if one of the damaged parts is repaired during this time, no actual problem occurs.

[0031]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a girdle rack with a power supply device according to one embodiment of the present invention.

As shown in FIG.
Is mainly composed of a pole portion 2, a hanger portion 3, a housing 4, a caster 5, and a power supply device 10. Pole part 2
Are arranged upright in the vertical direction. The pole part 2 is composed of a double pole, and an outer pole 2a fixed to the housing 4.
The inside pole is configured to be able to enter and exit from inside. At an arbitrary position, the upper and lower positions of the inner pole are fixed by the handle 6a of the joint portion 6 of the double pole. Under the joint 6, a tube guide 7 is attached to the outer periphery of the outer pole 2a. A tube connected to the infusion container hung on the hanger part 3 is passed through the tube guide 7, and the position of the tube can be regulated along the pole part 2. As a result, by extending and retracting the pole portion 2 up and down, the height of the infusion container hung on the hanger portion 3 can be easily adjusted according to the height of the patient, and the infusion can be performed well. .

A hook 8 for hooking a power cord 50 is provided on a side surface of the pole portion 2. When the power supply device is not used, if the power cord 50 is rolled around the hook 8 and hung, the power cord 50 can be easily moved without hindering the movement of the gartle rack 1 using the casters 5.

The hanger portion 3 is attached to the upper end of the pole portion 2 and has a hook 3a for hanging an infusion container.
Are provided at both ends. The housing 4 is attached to the lower end side of the pole part 2 and includes a metal chassis and a molded case. As described above, the housing 4 can be easily configured as a part of the gertle rack 1 by the metal chassis and the mold case.

The power supply 10 is housed in the housing 4. The housing 4 is mounted on the casters 5, and the casters 5 have, for example, six legs each having a roller. The number of legs is 3, 4, 8, 10
Any suitable number such as books,...

The housing 4 and the power supply 10 are
According to the horizontal size of the casters 5 such as the horizontal length of the feet of the caster 5 and the number of feet of the casters 5, the center of gravity of the gertle mount 1 is overturned by a manual calculation or a computer simulation. It is configured to have a weight that is less than the height determined to be difficult. Therefore, a heavy infusion container is hung on the hanger part 3,
When pushing the pole portion 1 or the like and moving the caster 5 with the caster 5, for example, the girdle rack 1 having a total weight of about 20 kg and a low center of gravity is unlikely to fall down. In particular, since a nurse or the like does not need to support the gantry frame 1 by hand during the operation, a high-quality operation can be expected without disturbing the operation.

On the front panel of the power supply device 10, 3P outlets 20 with grounding electrodes are divided into two rows and are vertically arranged two by two in total. Also, two protective ground terminals 21 are arranged vertically.

As shown in FIG. 2, on the rear panel 10a of the power supply device 10, two 3P outlets 20 with grounding electrodes are vertically arranged and provided. The breaker switch 11a of the overcurrent breaker 11, which will be described later, The power supply lamp 14 illuminated to indicate whether or not the power supply by the power supply device 10 is normally performed by the breaker switch 13a of the earth leakage breaker 13 described later can be visually and easily understood by the lighting state.

In FIG. 1, a 2P plug 51 is provided at the end of the power cord 50.
The P plug 51 is connected to a 2P outlet as an existing wall outlet. Incidentally, it is also possible to connect such a 2P plug 51 to a 3P outlet. In particular, the power cord 50 may be fixedly connected to the power supply device 10 or may be detachably connected.

FIG. 3 shows a circuit configuration inside the power supply device 10. In FIG. 3, a power supply device 10 includes an overcurrent breaker 11, a transformer 12, an earth leakage breaker 13, a power lamp 14, 3P plugs C1 to C6 corresponding to the 3P outlet 20 in FIGS. 21a and 21b, and protection resistors RS1 and RS2, for example, are configured to have a rated input of 100 VAC, a rated output of 100 VAC, and a capacity of 1 KVA.

The transformer 12 is supplied with power through a power cord 50 having a 2P plug 51 and has a structure in which a primary side and a secondary side having a 1: 1 voltage ratio are electrically insulated. . Preferably, transformer 12 has a double insulation structure. By doing so, the transformer 12 having a double insulation structure
And the protection resistors RS1 and RS2 function as a pseudo ground circuit that can provide a potential closer to the ground potential.

The overcurrent breaker 11 is, for example,
A breaker that trips at A and is connected to the primary side of the transformer 12. If an excessive current flows in the power supply 10,
Since the overcurrent breaker 11 operates and the breaker falls,
Each circuit and wiring in the power supply device 10 can be prevented from being destroyed.

The earth leakage breaker 13 has, for example, a sensitivity current 6
It is a breaker of mA and is connected to the secondary side of the transformer 12. When an electric leakage occurs in the medical electric equipment connected to the 3P outlets C1 to C6, the electric leakage breaker 13 drops, so that danger to the patient and the medical electric equipment can be reduced.
The sensitivity current of the earth leakage breaker 13 is increased or decreased according to the use (that is, what kind of medical electrical equipment is used), and for example, a minute leakage may seriously affect a patient. In such a case, the current may be 1 to 3 mA.
It may be 0 to 30 mA.

The power supply lamp 14 is turned on when the power supply is normally performed without the power leakage breaker 13 or the overcurrent breaker 11 being operated by the power supply device 10. In particular, since the power supply lamp 14 is provided on the secondary side of the transformer 12, even when the earth leakage breaker 13 falls, the lighting is turned off, which is practically convenient.

The 3P outlets C1 to C6 with ground electrodes are
Power is supplied from the secondary side of the transformer 12 via the earth leakage breaker 13. These 3P outlets C1 to C6
Preferably, what is called a hospital grade is used. The ground poles of the 3P outlets C1 to C6 are connected to the secondary side of the transformer 12 via protection resistors RS1 and RS2, and are directly connected to the protection ground terminals 21a and 21b, respectively.

The protective ground terminals 21a and 21b are connected to the ground poles of the 3P outlets C1 to C6. Therefore, in a medical facility having a grounding facility, the protective grounding terminal 2
If 1a or 21b is connected to the ground of this medical facility,
The ground electrode of the 3P outlet can be more reliably and strictly set to the ground potential. There are two protective ground terminals, but only one may be used. By using both protective ground terminals, the ground resistance can be reduced, and the ground potential can be reliably obtained even when one of them does not function. be able to.

The protection resistors RS1 and RS2 are made of different materials and are connected in parallel. These resistances include winding resistance, carbon resistance, cement resistance and the like. By using two protection resistors of different materials in this way, even if the protection resistor RS1 or RS2 is destroyed due to a device failure, aging, or any other unpredictable reason, both of these materials having different materials are used. The possibility of simultaneous destruction is almost eliminated. These resistors R
Since S1 and RS2 are connected in parallel, even if one of the resistors RS1 and RS2 is destroyed, the remaining resistor RS1 or RS2 can maintain the minimum function as a protection resistor.

Next, the operation of the present embodiment configured as described above will be described with reference to FIGS. First, FIG.
In the above, the infusion container is hung on the hanger portion 3 and the infusion container is arranged at an appropriate height higher than the position of the patient, whereby the infusion is performed using the infusion put in the infusion container. At this time, since the relatively heavy power supply device 10 including the transformer 12 and the like is housed in the housing 4, the center of gravity of the gertle rack 1 is reduced according to the weight of the power supply device 10, The stability of the gartle rack 1 against overturn is remarkably improved. Further, since the housing 4 is mounted on the casters 5, the movement of the relatively heavy girdle rack 1 can be performed without any problem by pushing the pole portion 2 and the housing 4 by hand.

On the other hand, as an existing wall outlet, AC1
When the 2P plug 51 is connected to a 2P outlet that does not have a grounding pole of 00V, in FIG.
Power is supplied to the primary side at 100 VAC via a power cord 50. The transformer 12 supplies power of AC100V to two pins other than the ground electrode among the 3P outlets C1 to C6 with the ground electrode connected to the secondary side. at the same time,
With the pseudo ground circuit formed by the secondary side of the transformer 12 and the protection resistors RS1 and RS2, the ground poles of the 3P outlets C1 to C6 with ground poles function as ground poles. That is, the 3P outlets C1 to C6 literally function as 3P outlets with ground electrodes.

Medical electrical equipment having a 3P plug with a ground electrode is connected to a 3P outlet with a ground electrode. Then
The medical electrical device can be operated while the grounding state of the medical electrical device is kept good. At this time, since a plurality of (that is, six) 3P outlets C1 to C6 with ground electrodes are provided, a plurality of medical electrical devices can be connected. The power cord is not scattered to the floor as in the case where power is supplied from a wall outlet to a plurality of medical electrical devices using a thigh-foot wiring.

In particular, since the earth leakage breaker 13 having high current sensitivity is provided on the secondary side of the transformer 12, even if earth leakage occurs in medical electrical equipment connected to the 3P outlets C1 to C6, Activating the earth leakage breaker 13 can reduce the danger to the patient and the medical electrical equipment.

As described above in detail, according to the present embodiment, even in a medical facility where a 3P outlet with a ground electrode is not provided as a wall outlet, an infusion is performed in an operating room or the like, and at the same time the medical electrical equipment is used. By placing the girdle rack 1 with the power supply device around the patient to be treated or examined, the space around the patient can be effectively used, and drip can be performed while a plurality of medical electrical devices are highly safe and easy to use. Power supply can be performed well. At this time, it is possible to prevent the power cord from being scattered on the floor in the operating room. In particular, the power supply 10 is placed in a space where there is almost no use, usually under a conventional girdle rack (on a caster of the girdle rack). As a result, the space in the operating room can be used much more effectively as compared with the case where the power supply device 10 is separately installed, and the power supply device 10 including the transformer 12 and the like is basically attached to the pole of the gertle rack 1. By providing the weight under the portion 2, the weight can be effectively used for improving the stability of the gertle rack 1 against overturning.

In the above embodiment, AC100V
Although the description has been given of the case where the power is supplied, the present embodiment is effective regardless of the type of the power. Further, the number of 3P outlets and the number of protective ground terminals provided on the front and rear panels of the power supply device 10 can be appropriately increased or decreased according to the application.
