Description

  The present invention relates to a disposable medical warm electric heat jacket suitable for use for warming a patient at the time of treatment when performing a treatment such as an operation by a hypothermia method.

  In the hypothermic method (hyperothermic), treatment such as surgery is performed after the patient's body temperature is lowered by lowering the room temperature to about 17 ° C. and the function of metabolism is lowered.

  However, when treatment such as surgery is performed at such a low temperature, there is a problem that the patient is cold and cannot withstand long-term treatment.

  Therefore, as seen in US Pat. No. 5125238, it is called a warming cover, and warm air is sent between blankets composed of two thin films to warm the patient. There is an example. Warm air is made of a box with a built-in heater, and is connected to the blanket with a flexible tube. Therefore, warm air can be sent from a box-like body with a built-in heater to a blanket placed on the patient via a large-diameter tube, and the whole or part of the patient's body can be warmed. Various blanket shapes are available, such as a large size, a small size, or a dedicated arm.

  However, the warming cover as described above has a problem that the equipment cost is high because a box-like body with a built-in heater is required, and it is difficult to use in a small hospital. Further, since the box-like body and the blanket are connected by a relatively large diameter tube of 30 to 50 mm, there is a risk of getting in the way, tripping over, or catching hands. If you trip over and get caught in a tube, you can pull a blanket on the patient, which can cause serious accidents for the patient during surgery.

As a means for solving the above-described background art, there is a proposal of applying an electric blanket to a patient. However, medical warmth jackets must be disposable or can be used cleanly in the treatment room and do not warm the entire body from the core. There has not yet been proposed a product that can be put into practical use in terms of functionality and cost because it must be warmed by feeling.
USPatent: 5,125,238, first page

  In view of the above-described prior art, an object of the present invention is to provide an electrothermal medical thermal electric thermal jacket that is disposable, clean, and can be heated safely.

The medical electrothermal jacket of the present invention capable of solving the above-mentioned problem is a disposable medical thermal electrothermal jacket used to take warmth due to the thermal sensation of the patient during treatment by the hypothermia method,
A jacket main body, an electric heating cord formed by combining a heater wire and a sensor wire housed in the jacket main body, a male main body side connector connected to the electric heating cord, and a female connecting to the main body side connector A power supply side connector of the mold, and an energization controller that is disposed between the power supply side connector and the power plug and performs energization control on the electric heating cord,
The jacket body is composed of a pair of upper and lower heat-welding sheet materials having a heat-sealing function, and fixes the electrothermal cord between heat-sealing beams by mutual heat-sealing. A battery charger and a battery capable of supplying power to the electric heating cord with the power plug removed from a power socket are provided.

  Therefore, the medical warm electric heat jacket of the present invention can be manufactured with a clean, warm, safe and inexpensive jacket body. The surface of the jacket main body can be covered with a non-woven heat insulating sheet to increase the heat retaining property. Since the jacket body can be made of resin only, it is clean because it is not dusty unlike paper. Since one or two nonwoven fabrics are interposed between the electric heating cord and the patient, it is highly insulated and safe. Furthermore, since the main constituent material of the main body is only a 1 mm surface heat-retaining sheet, 1 to 2 mm heat-sealing sheet material, and an electric heating cord, it can be manufactured at a low cost so as to be disposable.

  The energization controller includes a battery charger and a battery that can supply power to the power cord with the power plug removed from a commercial power socket.

  Therefore, the power cord in the jacket body can be energized in a cordless state by removing the power plug from the socket and placing it under the bed together with the energization controller while the battery is charged. During the operation, the electric wire does not get in the way of the practitioner's feet, and a safe operation can be performed.

  The sheet material for heat fusion may be a non-woven fabric or foam material made of flame retardant polyurethane, or polyolefin, polyester or polyamide, and the average fiber diameter may be 3 to 30 μm. By setting the fiber diameter to 3 to 30 μm, it is possible to obtain a fabric that is flexible, has high heat retention properties, and has a good touch. Further, the cloth made of these resins is strong, and the fibers are not crushed and dissipated and are clean.

  The medical warm electric heat jacket according to the present invention having the above configuration does not require a large facility for producing warm air and can be easily used even in a relatively small hospital. In addition, since a large-diameter pipe or the like for supplying warm air is not required, it can be used safely.

  As described above, since the present invention is a medical warm electric shock jacket as described in the claims, it is possible to smoothly perform treatments such as surgery by the hypothermia method without burdening the patient.

  The medical warm electric shock jacket of the present invention has a battery charger and a battery, and during operation, the power plug can be removed from the socket and carried under the bed. There are few, and it can treat safely, without removing a jacket main body from a patient.

  In addition, the medical temperature-sensitive electric heat jacket of the present invention is an electric type, and can reduce the equipment cost including the equipment on the power source side, and can implement the hypothermia method even in a small hospital.

  As the sheet material for heat fusion, since it is composed of a non-woven fabric made of flame retardant polyurethane or a foamed material thereof, or a non-woven fabric of flame retardant polyurethane, polyolefin, polyester or polyamide having an average fiber diameter of 3 to 30 μm, heat retention It is good, clean, strong and inexpensive, and can be disposable.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 are a partially enlarged sectional view showing an internal configuration of a jacket main body 1 according to the present invention and a plan view of the portion, and FIG. 3 is an overall configuration diagram showing a connection relationship between this and a power supply portion. . 4 and 5 are plan views showing other embodiments, respectively. Although the main body 1 is described as a jacket, it can also be referred to as a blanket from the viewpoint of using a nonwoven fabric.

  In FIG. 1, the jacket main body 1 according to an embodiment of the present invention is a state in which the sheet materials 2 and 3 for heat fusion made of a foam material made of flame-retardant urethane having a thickness of about 1 to 2 mm face each other up and down. The electrothermal cord 4 is sandwiched between them, and the films 2 and 3 are heat-sealed. An example of an adult size with dimensions of about 1m x 2m is shown. The outer surface of the heat-fusing sheet material 2 on the upper surface is coated with heat insulating sheets 5 and 6 made of a polyethylene blend material having a thickness of about 1 mm.

  The electric heating cord 4 has a signal line capable of detecting temperature by a change in resistance value, and an electric heating line that generates resistance heat by passing a current based on voltage application. A pair of resistance wires wound forward and backward for demagnetization can also be used. It is assumed that the electric heating cord 4 has two cores. As shown in FIG. 2, the electrothermal cord 4 is fixed between the heat fusion beams 7 and 7 by the heat fusion of the sheet materials 2 and 3 for the upper and lower heat fusion.

  With the above configuration, the jacket main body 1 is composed of the heat-bonding sheet materials 2 and 3, so it does not slip between the heat-insulating sheets 5 and 6, the heat-insulating sheet 6 contacts the human body, does not slip, and the bed On the top, it can be comfortably adapted to the human body. Moreover, since the heat-fusing sheet material 2 is made of a resin having an average fiber diameter of 3 to 30 μm, it is strong and clean. Moreover, since the heat insulating sheet 5 is coated on the outer surface, the heat retaining property is good and hygienic. The control temperature of the electric heating cord 4 is basically 37 ° C. which is substantially the same as the human body temperature.

  3, assuming that the patient (not shown) is lying on his / her back on one end of the jacket body 1, a notch 8 is provided in a portion corresponding to the neck of the patient. Further, a male main body side connector 9 is provided on the side portion. The connector 9 is not necessarily connected directly to the main body 1. You may comprise separately via an electric wire. In this example, an example in which the main body is directly connected is shown.

  The number of wires of the connector 9 is a total of four cores including the reciprocating wires when one electric heating cord 4 is incorporated in the main body 1 in a zigzag manner. Further, perforations 10 are provided at positions corresponding to the vesicle and abdomen of the patient of the electrothermal jacket body 1 so that the portions can be opened. A perforation 10 is also included for releasing the foot. Therefore, during the operation, the perforation 10 can be cut as necessary to open the required portion.

  The main body side connector 8 is connected to a female connector 11. The female connector 11 is connected to an energization controller 13 via a 48V energizing wire 12, and the energization controller 13 is connected to a 120V energizing wire 15 via an AC-DC converter 14. 15 is connected to the power plug 16. The AC-DC converter 14 converts 120V alternating current into 12V direct current. The power plug 16 is connected to a 100 to 120V AC power socket (not shown) in a timely manner. (A) As shown enlarged in the figure, the energization controller 13 is provided with a parallel circuit of a DC-DC converter 17 and a battery charger 18 for converting 12V DC to 48V DC, and the battery charger 18 is 12V DC. A battery 19 for storing electric power is provided. The output end of the DC-DC converter 17 is connected to the temperature controller 20. The temperature controller 20 is connected to the electric wire 12 and supplies a 48V DC power source to the electric heating cord 4 so as to control the jacket temperature to a set temperature of 37 ° C.

  On the other hand, a changeover switch 21 is provided in a parallel circuit of the DC-DC converter 17 and the battery charger 18, and a contact piece of the switch 21 is an output terminal T 1 of the AC-DC converter 14 and an output terminal of the battery 19. 19 can be switched and connected. Therefore, when the switch 21 is connected to the terminal T1, the output power of the AC-DC converter 14 can be stored in the battery 19, and the power can be supplied to the electric heating jacket 1. If the switch 21 is switched to the terminal T2, the stored power of the battery 19 can be supplied to the electric heating jacket 1 with the plug 16 removed from the power socket. In general, a power jacket is inserted into a socket and charged before treatment, and when the electric heating jacket 1 is actually used, the power plug 16 is removed from the socket, and the electric heating jacket 1 is used by using the stored power of the battery 19.

  The connectors 8 and 11 do not naturally separate from each other, but can be easily separated from each other when pulled by hand. Therefore, even if the external electric wire is pulled by mistake and the connector 11 is pulled, it can be removed from the connector 8. The control method of the temperature controller 20 of the energization controller 13 may be a general one, for example, a type in which the power is turned on / off with 37 ° C. as a reference.

  With the above configuration, the medical electrothermal jacket 1 according to the present invention has a system configuration as illustrated, and the main body portion of the electrothermal jacket 1 can be made disposable and can be used for treatment by the hypothermia method. Since the connectors 8 and 11 can be separated into male and female, portions other than the main body side connector 8 can be used continuously.

  Since the members on the power source side are the power plug 14, the energization controller 13, the AC-DC converter 14, and the electric wires 12, 13, it can be configured inexpensively, compactly and safely compared to a hot air supply device or the like.

  Since the battery charger 18 and the battery 19 are included and the power plug 16 can be removed from the socket and carried under the bed during the operation, the surgeon does not have to worry about tripping over the electric wire during the operation, and the jacket body is attached to the patient. It can be safely treated without being pulled off. Furthermore, since the sheet materials 2 and 3 for heat fusion and the heat retaining sheets 5 and 6 are made of resin having an average fiber diameter of 3 to 30 μm, they have good heat retention, are clean, strong and inexpensive, and are disposable. It is possible.
