Definitions
- the present invention relates to an analgesic device that can be attached to the outside of a patient's body and carried.
- analgesics, etc. were regularly administered to patients in order to relieve or relieve their pain. Therefore, patients must visit the hospital regularly or stay in the hospital for a long period of time.
- An object of the present invention is to obtain a simple and portable analgesic device that can be attached to the outside of a patient's body and can inject a drug solution into the body at the patient's discretion.
- the portable analgesic device of the present invention has a continuous drug solution injector that continuously flows out the drug solution for a predetermined time, and an on-off valve that is connected to the outlet of the injector to block the outflow of the drug solution. And a three-way connector that is connected to the outlet of the on-off valve and has a three-way flow path.
- One is a flexible server that is connected to one end of the three-way connector to store the chemical solution, and the other is the pressure that is connected to the other end of the three-way connector and opens only when the chemical solution exceeds a predetermined pressure. Consists of a valve
- a continuous drug solution infusion device having a predetermined volume and duration is prepared in advance, and a predetermined drug solution is injected into the predetermined amount of the drug solution according to the patient's symptom.
- the on-off valve is opened to transfer the drug solution into the reservoir for a specified long period of time.
- the transfer time of the drug solution from the syringe to the reservoir is almost the same as the duration of the effect of the drug solution.
- the patient In preparation for the next pain, the patient can be replenished with the syringe by a qualified person at the hospital or at home.
- FIG. 1 is a plan view of the portable analgesic device of the present invention.
- Fig. 2 is a vertical cross-sectional view seen from the ⁇ — ⁇ line of Fig. 1.
- Fig. 3 is an explanatory diagram of the operation when the drug solution is injected into the drug solution continuous injector.
- Fig. 4 is an explanatory diagram of the operation when the chemical solution is transferred from the injector to the reservoir.
- Fig. 5 is an explanatory diagram of the operation when the transfer of the chemical solution to the reservoir is completed. It is an operation explanatory drawing of Rusai.
- the portable analgesic device of the present invention is mainly connected to a drug solution continuous injector 1 that continuously drains the drug solution for a predetermined time and an outlet of the injector 1.
- a three-way connector 3 that is connected to the outlet of the on-off valve 2 and has a three-way flow path, and a three-way connector 3 that is connected to one end of the three-way connector 3 to block the outflow of the drug solution. It consists of a flexible reserver 4 for storage and a pressure one-sided valve 5 that is connected to the other end of the three-way connector 3 and opens only when the chemical solution exceeds a predetermined pressure.
- the on-off valve 2 and the three-way connector 3 are connected by the Mesrua connector 6, and the Osurua connector 7 is connected to the outlet of the pressure one-way valve 5.
- the Mesrua'connector 6 provides space for facilitating the operation of the on-off valve 2, and the Osurua connector facilitates the connection of catheters and the like.
- the drug solution continuous injection device 1 there is a drug solution continuous injection device (Special r No. 1384289) developed by the applicant.
- This injector has the function of connecting the injection part and the outflow part of the drug solution with a balloon, injecting the drug solution into the balloon, and discharging the drug solution from the outflow part for a long period of time.
- the chemical injection part 12 and the chemical outflow part 13 are attached to both ends of the cylindrical body 11, and the palline 14 is attached to the outer circumference of the cylindrical body 11, and the inside of the palin 14 and the cylinder. Connect the inside of the main body 11 to the communication hole 15. It has a communication structure.
- the cylindrical body 11 may be omitted, and the injection part 12 and the outflow part 13 may be directly connected by a balun 14.
- the injection section 12 is provided with a check valve 121 to prevent backflow of the injected drug solution.
- Parin 14 is made of elastic material and can hold a predetermined amount of chemical solution.
- a control passage 131 is provided in the outflow section 13 to control the outflow time of the drug solution.
- a safety cover 16 is attached to prevent external action when the balun 14 is inflated.
- the Meslua'connector 6, the three-way connector 3, and the Osurua' connector 7, use a commercially available product.
- Reserver 4 is made of durable flexible material (eg, polyetylene, polypropylene, etc.) and is molded into a spherical, circular, bellows shape, etc. Reserver 4 is , It can be detachably attached to the three-way connector 3 in case of damage or contamination.
- a commercially available umbrella valve is preferable.
- This umbrella valve is normally closed and is set to open when the internal pressure exceeds, for example, about 250 mm Hg.
- This set pressure does not work at the injection pressure of the drug solution from the injector 1 to the reserver 4 (about 100 0 — 2 0 0 Dragon H g), but when the reservoir 4 is filled with the drug solution, it does not work. It is lower than the pressure when the server 4 is compressed (about 350 — 4 0 0 injection H g).
- a drug solution eg, saline solution, bud sugar solution, antibiotic solution, sedative, analgesic, heparin, nitroglycerin solution, etc.
- a drug solution eg, saline solution, bud sugar solution, antibiotic solution, sedative, analgesic, heparin, nitroglycerin solution, etc.
- the drug solution is temporarily stored in the balloon 14 o
- the capacity and duration of injection of the injector 1 are selected in advance according to the patient's symptoms.
- this device After preparing as described above, this device is fixed to the patient's body, and a catheter or the like (not shown) is used to connect the Osurua * connector 7 to the body.
- the above-mentioned drug solution may be injected after the device is fixed to the patient's body.
- the drug solution will be a three-way connector 3 Pressure One-sided valve 5, Osurua'Connector 7 is squeezed and leaked to the outside (inside the patient's body).
- the device can be reused by repeating the above operation. Of course, it may be used for each use.
- the device of the present invention can be applied not only to ordinary disease treatment and end-of-life care but also to emergency treatment. It can be applied not only to analgesia but also to sedation, detoxification-antipyretic, nutritional supplementation, etc.
