  JP 2007-29562 A (Japanese Patent Application No. 2005-219498 Extruding Device)

  JP 2009-226209 A (Japanese Patent Application No. 2009-044530 semi-solidified nutrient injection device)

  The prior art (0002) has a flexible and bag-shaped air bag that inflates when supplied with air, and a receiving member that faces the air bag and receives the pressure of the inflated air bag. .

  A bag-like container containing a semi-solid nutrient is sandwiched between the airbag and the receiving member, and the bag-like container is compressed by manually supplying air to the airbag and inflating the bag. The above-mentioned semi-solid nutrient is extruded, but has the following problems.

  Firstly, the method of Patent Document 1 has a problem that it is difficult to predict the time at which the nutrient has finished flowing out of the container, and it cannot flow out in a short time.

  That is, the speed at which nutrients flow out is large at the initial stage of pressing, but as the remaining amount in the container decreases, the flow rate decreases and almost no nutrients flow out after a predetermined time.

  Even if re-pressurization is performed when the outflow speed becomes small, the same state is repeated.

  For this reason, when trying to flow out in a short time, it is necessary to pressurize again when the outflow rate is reduced, and a very troublesome operation is required.

  Secondly, the method of Patent Document 1 has a problem that a considerable amount of nutrients remain in the container without flowing out.

  Therefore, after extruding with a pressure bag to some extent, it was necessary to take out the bag-shaped container from between the pressure bag and the receiving member and squeeze out the residual liquid by manual work.

  In the prior art (0003), an injection device for injecting the semi-solid nutrient from a nutrient container filled with the semi-solid nutrient through a pump tube, the base and the base A rotor rotatably supported on a table, and the pump tube can be mounted in the groove-like gap on an outer peripheral edge of the rotor, and the pressure contact member is placed in the proximity with the pump tube mounted The semi-solidified nutrient injection device, wherein the roller pushes the pump tube by moving the rotor to a position and rotating the rotor.

  The following problems are assumed in this method.

  Usually, the semi-solidified nutrient injection device requires a tube for transporting from the nutrient container to the gastrostomy site.

  In order to inject the semi-solid nutrient, the tube connected to the nutrient container is made longer, or another tube is connected to the grooved gap to inject the semi-solid nutrient. It must be possible to do.

  Therefore, the longer the tube connected from the nutrient container to the gastrostomy site, the greater the possibility that the semi-solid nutrient will remain in the extended tube in this infusion device. .

  In this injection device, it is not always easy to efficiently inject nearly the entire amount of the semi-solidified nutrient in the nutrient container.

  In addition, when the possibility that semi-solidified nutrients remain in the tube increases, this increases the time and effort for cleaning the remaining semi-solid nutrients, and burdens caregivers after use. It may increase.

  If the operation is forcibly continued to completely inject the semi-solidified nutrient remaining in the tube, air may be injected into the body via the gastrostomy.

  The present invention prevents the semi-solid nutrient from remaining in the pack as in the prior art (0002).

  When the bottom of the bag-like container 3 is inserted into the groove opening 2a of the winding shaft 2 and one winding shaft 2 is electrically driven (battery), the mechanical winding force of the winding shaft 2 A bag-like container 3 filled with nutritional food or the like placed on the base plate 1 is wound on the winding shaft 2 from the bottom.

  By winding around the winding shaft 2 from the bottom of the bag-like container 3, as the volume of the bag-like container 3 decreases, an internal pressure is generated inside and the nutritive food etc. inside the bag-like container 3 is opened from the bottom. It is characterized by being extruded almost completely via

  In the present invention, it is not difficult to predict the time at which the nutrients finish flowing out of the container as in the prior art (0002).

  Even if it is difficult to predict, it can be easily adjusted to a desired time by electrically changing the setting.

  The interval between the injections 5 can be set to a standard 4 to 10 minutes. If there is a special request, any other time can be set.

  As in the prior art (0002), the present invention provides a bag-like container filled with a semi-solid nutrient with the pressure of an air bag that is inflated by air supply, by the cooperation of the air bag and the receiving member. It does not push out solid nutrients.

  In the prior art, the pressure is not uniformly applied to the entire bag-like container, and since there is little pressure in the peripheral part of the bag-like container, the semi-solid nutrient tends to remain around the inside of the bag-like container.

  In the present invention, instead of applying pressure to the whole bag-like container as in the prior art, as the volume of the bag-like container 3 is reduced by wrapping around the winding shaft 2 from the bottom of the bag-like container 3, Internal pressure is generated from the bottom, and the nutritional food and the like inside the bag-like container 3 can be pushed out almost completely.

  Therefore, in order to inject the semi-solid nutrient remaining in the bag-like container, an operation of pushing out by a technique is not required.

  As in the prior art (0003), the present invention eliminates the need for a long tube because a negative pressure generated in the tube is attached to the groove-like gap and is not sucked or injected.

  Therefore, since the distance from the container to the gastrostomy site can be as short as possible, an existing short tube can be used.

  Moreover, the nutritional food etc. remain in the tube, and cleaning after use is easy.

  In the present invention, unlike the prior art (0003), there is no risk that air is accidentally injected into the body via the gastrostomy.

  When the bag-like container 3 is wound around the winding shaft 2 from the bottom of the bag-like container 3, as the volume decreases from the bottom of the bag-like container 3, an internal pressure is generated inside and the bag-like container 3 is inside the bag-like container 3. Since nutritional foods and the like are injected into the patient through the tube 4 connected to the opening from the bottom of the bag-like container 3, almost the entire amount is pushed out.

  The present invention does not inject nutritional food or the like into a patient depending on gravity.

  Therefore, the installation location and position are not chosen.

  In addition, since the installation direction (orientation) of the apparatus is not selected, the apparatus can be installed in any direction (orientation) without being affected by the patient's posture or whereabouts (bed, futon on the tatami mat, etc.).

  The present invention does not require a long tube or an additional connection tube for further extension.

  Standard tube lengths available on the market can be used. Also, the injection time can be set to a desired standard 4 to 10 minutes, and if there is a special request, any other time can be set.

  Unlike manual handle injection devices, it does not require strong human power.

  The present invention can be easily used as a nutritive food or the like, even if it is a semi-solidified nutrient having a high viscosity, like a nutritive food having a low viscosity.

  Without depending on the inherent viscosity of the nutritional food, etc., the nutritional food etc. easily remains in the bag-like container 3 from the bag-like container 3 and is quickly injected into the gastrostomy patient via the gastrostoma. Possible gastrostomy patient nutrition supplement injection support device.

  The present invention does not inject nutritional food or the like into a patient depending on gravity.

  Therefore, the installation location and position are not chosen.

  In addition, since the installation direction (orientation) of the apparatus is not selected, the apparatus can be installed in any direction (orientation) without being affected by the patient's posture or whereabouts (bed, futon on the tatami mat, etc.).

  Since the present invention is battery-driven, it can be easily reduced in size and weight, so that it can be worn under a patient's clothes and can be carried.

  Therefore, the patient can also perform normal daily life (walking, shopping, etc.) and other social activities. Contributes to improving patient QOL.

  In addition, the patient can also travel. In that case, since maintenance of the necessary apparatus is cleaning of the tube 4 after use, it is possible to carry a plurality of tubes 4 even when traveling for several days. It is unnecessary to clean the tube 4 at a travel destination. Contributes to improving patient QOL.

  Since the device of the present invention is simple and easy to operate, it can be operated by a patient, a family, a caregiver, and the like.

  Also, for example, it is possible to inject a 400 Kcal nutrient pack (bag-like container 3) at a time in accordance with the normal meal time of a day without any problems.

  Therefore, the patient can replenish nutrients and the like using this device together with the family meal time.

FIG. FIG. 3 is a perspective view showing an embodiment in which the bottom portion of the bag-like container 3 is inserted into the groove opening 2 a of the winding shaft 2 and started to be wound on the winding shaft 2. These are perspective views which show the Example by which the bottom part of the bag-shaped container 3 is wound up by the groove opening 2a of the winding shaft 2 of this invention.

  The bottom of the bag-like container 3 is inserted into the groove opening 2 a of the take-up shaft 2. As the take-up shaft 2 is driven and rotated, the bag-like container 3 is wound by the cooperation of the take-up shaft 2 and the base plate 1. When wound around the spindle 2, the volume of the bag-like container 3 is reduced, so that an internal pressure is generated in the bag-like container 3, and the nutritive food filled inside is compressed by the internal pressure and pushed out of the bag-like container. The tube 4 is then injected into the patient via the gastrostomy.

  The bag-like container 3 is disposed on the base plate 1, and the bottom of the bag-like container 3 is inserted into the groove opening 2 a of the winding shaft 2.

  As the winding shaft 2 is driven to rotate, when the bag-shaped container 3 is wound around the winding shaft 2 by the cooperation of the winding shaft 2 and the base plate 1, the nutritional food filled in the bag-shaped container 3 Etc. are compressed, pushed out of the bag-like container by internal pressure, and injected from the tube 4 to the patient via the gastrostomy.

Effects of the embodiment

  In this device, the semi-solidified nutrient filled in the bag-like container 3 is easily and almost completely dispensed with the patient's stomach via the tube 4 so that there is no residue in the bag-like container 3 in a short time. Provided is a nutritional supplement supplementing device for gastrostomy patients that can be injected into the stomach.

  By winding the winding shaft 2 from the bottom of the bag-like container 3, as the volume of the bag-like container 3 decreases, internal pressure is generated inside, and the semi-solidified nutrient inside the bag-like container 3 is removed from the bottom. It is characterized in that it is extruded almost completely through the opening.

  The injection time can be set to the standard 4 to 10 minutes, and any other time can be set if there is a special request.

  In the present invention, instead of applying pressure to the whole bag-like container as in the prior art, as the volume of the bag-like container 3 is reduced by wrapping around the winding shaft 2 from the bottom of the bag-like container 3, An internal pressure is generated from the bottom, and the semi-solidified nutrient in the bag-like container 3 can be almost completely pushed out.

  Further, the semi-solidified nutrient in the tube is less left, and cleaning after use becomes easy.

  When the bag-like container 3 is wound around the winding shaft 2 from the bottom of the bag-like container 3, as the volume decreases from the bottom of the bag-like container 3, an internal pressure is generated inside and the bag-like container 3 is inside the bag-like container 3. Since the semi-solidified nutrient is injected into the patient through the tube 4 connected to the opening from the bottom of the bag-like container 3, almost the entire amount is extruded.

  The present invention does not inject semi-solid nutrients into patients depending on gravity.

  In addition, since the installation direction (orientation) of the apparatus is not selected, it can be installed in any direction without being affected by the patient's posture or whereabouts (on the bed, tatami mat, or futon).

  Standard tube lengths available on the market can be used. In addition, the injection time can be set to a desired standard 4 to 10 minutes. If there is a special request, any other time can be set.

  The present invention can be used easily even in the case of a semi-solidified nutrient having a high viscosity as in the case of a low viscosity.

  Without depending on the inherent viscosity of the semi-solidified nutrient, the semi-solid nutrient is easily left in the bag-like container 3 from the bag-like container 3 and easily passes through the stomach fistula in a short time. Nutritional supplement supply support device for gastrostomy patients that can be injected into patients with hemorrhoids.
