Description

  The present invention relates to an administration device that is used for oral or nasal, gastric, or transduodenal administration of nutrients or liquid foods to patients or elderly people who have difficulty ingesting solid foods. More specifically, the present invention relates to an administration device and an administration container that are optimal for administration of a nutrient composition such as a nutrient, liquid food, or the like that is solidified, gelled, or sol.

  Conventionally, in nutritional management of patients with nutrients or liquid food, administration by oral, nasal tube or PEG (Percutaneous Endoscopic Gastrostomy) has been performed. However, since both nutrients and liquid foods are liquid, for example, in the case of oral administration, it is impossible to take due to dysphagia, or even if taken, aspiration pneumonia May occur. In addition, when administered into the stomach through the oral or nasal tube or PEG, there is a problem of inflammation due to gastric-esophageal reflux, and particularly in the case of PEG, inflammation due to leakage from the fistula. Furthermore, there is a problem that diarrhea develops when the administration rate is too fast.

  In view of the above, recently, along with the development of gelled preparations, liquid nutrients and liquid foods are often solidified, gelled, or solled and administered.

  For this reason, in some cases, a syringe used to inject a solid agar impression material into the gap between teeth when taking a dental impression that is required by a dentist for the preparation of dentures and other dental caries. For example, see Patent Document 1), a so-called syringe, which is a combination of a synthetic resin cylinder having an injection port at the tip and a synthetic resin piston fitted into the rear end of the cylinder, is solidified. It has been used as an administration device for nutritional compositions such as gelled or solified nutrients and liquid foods.

  However, since the syringe with the largest volume is about 50 ml, a plurality of syringes are used to administer a solid, gelled or solutified nutritional composition of about 400 ml per time. There must be. In addition, depending on the hardness and viscosity of the solidified, gelled or solified nutritional composition, it becomes difficult to push the syringe by human force, which makes administration impossible or very cumbersome, which causes problems in operability. there were. In addition, although the syringe is originally disposable, it is used only once. However, as described above, since a plurality of syringes are required for a single administration, the cost becomes high, so the syringe is used once. The syringe was washed and repeatedly used, which was troublesome to handle.

In addition, a commercially available dressing container may be used as the administration container because it has a size that can accommodate almost the same capacity as that administered at one time, and its nozzle part is also compatible with the PEG tube. . However, in the case of this dressing container, there is a problem that the operability is poor because the container itself is not flexible and requires a continuous force to push out the nutritional composition filled therein. In particular, in the case of an adhering nutritional composition, it remains attached to the inner wall of the container, so that it is difficult to administer the entire amount, and therefore waste occurs, and in addition, the administration There was a problem that the amount became inaccurate.
Japanese Utility Model Publication No. 60-6532

  As described above, at present, there is no container or device that can efficiently administer an optimal amount of a solidified, gelled, or solated nutritional composition in a single administration, and therefore, such as a syringe or a dressing container. Since the administration work using substitutes was unavoidable, excessive labor was imposed on those engaged in hospitals and nursing homes.

  In view of this, the present invention eliminates the problems of substitutes such as the syringes and dressing containers as described above, and efficiently uses the nutritional composition that has been solidified, gelled, or solated in an optimal amount for a single administration.

In addition, it is possible to save the trouble of washing the administration device after administration of the nutritional composition.

  According to the invention of claim 6, the piston is inserted into the one end of the cylinder member, and the piston is stored in the cylinder in a state where a single dose of the nutritional composition is accommodated. Since it is in a fitting state that does not come out of the cylinder due to the mass of the liquid, it is solidified or gelled in the cylinder member by putting a liquid nutrient or liquid food in the cylinder member, and stirring and dissolving the gelling agent there The formulated nutritional composition can be completed. Moreover, since the nutritional composition produced in the cylinder member can be directly eaten with a spoon or the like, it can be used as a container for giving the patient the optimum amount of the nutritional composition 1 for one dose without using an administration device.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  First, the configuration of the nutritional composition administration device according to the embodiment of the present invention will be described.

  FIG. 1 is a front view in partial cross section of a nutritional composition administration device according to an embodiment of the present invention. FIG. 2 is a bottom view of the cylinder member of the nutritional composition administration device according to the embodiment of the present invention. FIG. 3 is a rear view of the first cap member of the nutritional composition administration device according to the embodiment of the present invention.

  A nozzle 3 for discharging the nutrient composition 1 is provided at one end of a cylindrical cylinder member 2 having a space in which the nutrient composition 1 which is a solidified, gelled or solified nutrient or liquid food can be accommodated. The provided first cap member 4 is detachably attached. The outlet portion of the nozzle 3 has, for example, a shape that fits into the insertion portion 6 of the gastrostomy tube 5, and facilitates connection between the nozzle 3 and the insertion portion 6, and the nozzle 3 and the insertion portion 6. And the nutritional composition 1 can be prevented from leaking.

  An independent piston body 7 as a pressing body for discharging the nutrient composition 1 from the nozzle 3 to the outside is slidably fitted in the cylinder member 2. Therefore, the cylinder member 2 has a sufficient length that can accommodate the nutritional composition 1 and the piston body 7. A link utilizing the so-called “lever principle” or the like that can move the piston body 7 to the first cap member 4 side at the other end of the cylinder member 2 on the opposite side to which the first cap member 4 is attached. A second cap member 8 having a booster moving means I comprising a mechanism is detachably attached.

  As a detachable structure of the cylinder member 2 and the first cap member 4 and between the cylinder member 2 and the second cap member 8, for example, a male screw is formed on the outer periphery of the cylinder member 2, and is screwed into the male screw. It is conceivable to form female screws in the first cap member 4 and the second cap member 8. In order to make the attachment / detachment operation easier, for example, as shown in FIG. 2, a vertical engagement groove 9 formed in the axial direction from the opening of the cylinder member 2 on the outer periphery of the cylinder member 2. A substantially L-shaped engagement groove 12 is formed as viewed from the front, which includes a circumferential horizontal engagement groove 10 continuous with the engagement groove and an engagement recess 11 following the horizontal engagement groove 10. In addition, the L-shaped engagement groove 12 and the engagement convex portion 13 that engages with the engagement concave portion 11 may be formed on the first cap member 4 and the second cap member 8. In this case, the engagement protrusions 13 of the first cap member 4 and the second cap member 8 are engaged with the vertical engagement grooves 9 of the cylinder member 2 and moved in the axial direction, and then the horizontal engagement grooves 10 are moved. The first cap member 4 and the second cap member 8 can be quickly attached to the cylinder member 2 by engaging and rotating to engage the engaging convex portion 13 with the engaging concave portion 11. Moreover, when removing the 1st cap member 4 and the 2nd cap member 8 from the cylinder member 2, it can remove rapidly by performing the reverse operation.

  The piston body 7 has a sufficient length to maintain sufficient sealing performance with the cylinder member 2, and grooves 15 and 15 for accommodating the O-rings 14 are formed at the front end portion and the rear end portion in the length direction. The groove 15 is fitted with an detachable elastic O-ring 14.

  A through hole 16 is provided at the center of the second cap member 8, and a slidable drive shaft 17 is inserted into the through hole 16. A pressing member 18 that is in contact with the piston body 7 is fixed to one end of the drive shaft 17 on the side attached to the cylinder member 2. A stopper member 19 is attached to the other end of the drive shaft 17 that is on the opposite side to which the pressing member 18 is attached so that the drive shaft 17 does not come out of the through hole 16 of the second cap member 8.

  Although the piston body 7 may be a solid body, it is preferable to form a meat relief recess 20 in the center portion in consideration of formability and material saving. In the embodiment of the present invention, the pressing member 18 of the drive shaft 17 is accommodated in the meat escape recess 20 so that the overall size becomes more compact.

  In the longitudinal direction of the drive shaft 17, locking grooves 21 having an axial cross-section in a sawtooth shape are formed at a constant pitch over a predetermined length. The locking grooves 21 are arranged at opposite positions on the circumference of the drive shaft 17. The first locking groove row 22 having a large number of locking grooves 21 and the second locking groove row 23 having a small number of locking grooves 21. And are formed.

  FIG. 4 is an enlarged front view showing the relationship between the locking member and the drive shaft of the nutritional composition administration device according to the embodiment of the present invention.

  The second cap member 8 is provided with a bearing portion 24 having an axis perpendicular to the axis of the through hole 16 at a position outside the through hole 16. A support shaft 26 provided at one end of the operation handle 25 is rotatably inserted into the bearing portion 24, and the operation handle 25 is attached to be rotatable about the bearing portion 24. A locking member 27, which is always given a rotational force in the clockwise direction in FIG. 1 by an urging means (not shown) such as a helical spring, is attached to an intermediate portion of the operation handle 25. The locking member 27 is attached to a position opposite to the bearing portion 24 across the drive shaft 17, and the locking claw 20 at the tip of the locking member 27 is locked in the locking groove of the first locking groove row 22. 21 or the engaging groove 21 of the second engaging groove row 23 can be engaged. As a result, the distance S from the bearing portion (fulcrum) 24 to the point of action where the locking claw 28 is engaged with the drive shaft 17 and the force point at the position of the hand moving the operating handle 25 from the bearing portion (fulcrum) 24. Depending on the relationship of the ratio of the size to the distance R, the booster moving means I composed of a link mechanism using the lever principle is realized. Thereby, it is only necessary to apply a force to the operation handle 25 that is smaller than the pressing force to the piston body 7 that is required for discharging the nutritional composition 1 from the nozzle 3.

  The drive means for moving the drive shaft 17 toward the first cap member 4 side is not limited to the above-described link mechanism using the so-called “lever principle” or the like, but also the “lever principle”. Well-known techniques such as a gear mechanism using cam, a cam mechanism, and a cylinder mechanism using the “Pascal principle” can be employed.

  In addition, a male screw is provided on the outer periphery of the drive shaft 17 and a female screw that is screwed to the male screw is provided on the second cap member 8 so as to be rotatable. The rotation of the drive shaft 17 is restricted to the female screw. If force is applied, the drive shaft 17 can be linearly moved. Therefore, if an electric motor is connected to the female screw via a speed reducer, the administration operation can be automated by providing an electric control device.

  FIG. 5 is a cross-sectional view of the main part showing the folded state of the handle of the nutritional composition administration device according to the embodiment of the present invention, and FIG. 6 shows the nutritional composition according to the embodiment of the present invention. It is principal part sectional drawing which showed the state which extended the handle of the administration apparatus.

  On the outer periphery of the central portion of the cylinder member 2, a handle bearing 29 having an axis perpendicular to the axis of the cylinder member 2 is provided. A rotation shaft 24 provided at a fulcrum portion 31 near the bent portion of the substantially J-shaped handle 30 is inserted into the handle bearing 29, and the handle 30 is attached so as to be rotatable around the handle bearing 29. It has been. The handle bearing 29 has two bearing plates 33, 33 arranged in parallel with the axis of the cylinder member 2 at a predetermined interval, and the cylinder member that hits between the two bearing plates 33, 33. On the outer periphery of 2, a convex portion 34 is provided that continues in a direction orthogonal to the axis of the cylinder member 2. On the other hand, on the outer periphery of the fulcrum portion 31 of the handle 30, two concave portions 35a and 35b that can be engaged with the convex portion 34 are formed with a phase of approximately 90 °. Thereby, the handle 30 can select two types of mounting postures that are shifted by about 90 ° with respect to the axis of the cylinder member 2.

  In the embodiment of the present invention, an operation piece 36 using a material that can be elastically deformed is incorporated in the fulcrum 31 of the handle 30 so that the mounting posture can be easily selected. The operation piece 36 is provided with a bearing 37 that can rotate around the rotation shaft 24 together with the handle 30, and a concave portion that does not change the distance from the center of the bearing 37 outside the bearing 37. 35 a and a concave portion 35 b whose distance from the center of the bearing 37 is reduced by performing an operation of elastically deforming the operation piece 36 are formed with a phase of about 90 °.

  Next, a method of using the nutritional composition administration device according to the embodiment of the present invention will be described.

  Fig.7 (a) thru | or FIG.7 (b) is explanatory drawing which showed the procedure which accommodates a nutrient composition in a cylinder member.

  First, as shown in FIG. 7 (a), the piston body 7 is inserted into the cylinder member 2 from one end of the cylinder member 2 away from the handle bearing 29, and the piston body 7 is inserted downward. Keep the cylinder member 2 in a vertical posture on the side. Next, as shown in FIG. 7B, the nutrient composition 1 is inserted from the opening side (upper side) of the cylinder member 2 on the opposite side of the piston body 7. The nutritional composition 1 is not limited to one that is solidified, gelled, or solated from the beginning. For example, a liquid nutrient or liquid food is put into the cylinder member 2 from the opening side (upper side) of the cylinder member 2 on the opposite side of the piston body 7, and a gelling agent is put into the cylinder member 2 to dissolve and stir and dissolve. It may be solidified or gelled. At this time, as shown in FIG. 7, the cylinder member 2 is in a substantially parallel posture (the projection 34 provided on the cylinder member 2 is engaged with the recess 35 a of the fulcrum 31 of the handle 30. Since the cylinder member 30 can be stably supported by gripping the handle 30 by hand, the stirring and dissolving operation can be easily performed.

  The O-ring 14 and the inner wall of the cylinder member 2 are in close contact with each other, and a large force is required to move the piston body 7 in a state where the piston body 7 is fitted into the cylinder member 2. Then, as shown in FIG. 7 (b) or 7 (c), the nutrient composition 1 is placed in the piston body 7 in a state where the cylinder member 2 is vertical and the piston body 7 is fitted into the cylinder member 2. In a state where the nutritional composition 1 is accommodated on the top, the piston body 7 is designed so as not to descend due to the weight of the nutritional composition 1.

  Once the nutritional composition 1 is accommodated in the cylinder member 2, the first cap member 4 is then attached to the opening side (upper side) of the cylinder member 2 as shown in FIG. In the case of the embodiment of the present invention, the engagement protrusion 12 of the first cap member 4 is engaged with the vertical engagement groove 9 of the cylinder member 2 and moved in the axial direction, and then the horizontal engagement groove 10 is moved. The first cap member 4 can be quickly attached to the cylinder member 2 by engaging and rotating the engagement concave portion 11 with the engagement convex portion 13.

  With the above procedure, the hardness and viscosity of the nutrition composition 1 are adjusted as necessary in a state where the piston body 7, the nutrition composition 1 and the first cap member 4 are integrated with the cylinder member 2. Therefore, a step of refrigeration may be added. At this time, as shown in FIG. 7, since the handle 30 is in a posture substantially parallel to the cylinder member 2, the whole is compact, so that a small storage space is sufficient when stored in the refrigerator. become. Moreover, since the container of the nutrition composition 1 is comprised by the cylinder member 2 and the piston body 7, if the 1st cap member 4 is removed, the nutrition composition 1 can also be made to eat directly with a spoon etc., administration It can be used as a container that gives the patient an optimal amount of the nutritional composition 1 without using the device.

  Next, immediately before administration of the nutritional composition 1, the piston body 7 is integrated with the cylinder body 2, the piston body 7, the nutritional composition 1, and the first cap member 4. It is necessary to attach the second cap member 8 having a moving means for moving the member 4 to the nozzle 3 side. In the case of the embodiment of the present invention, the pressing member 18 of the drive shaft 17 is directed to the piston body 7 side, and the engaging projection (not shown) of the second cap member 8 is vertically engaged with the cylinder member 2. After engaging with the groove 9 and moving in the axial direction, it is engaged with the horizontal engaging groove 10 and rotated to engage the engaging convex part 13 with the engaging concave part 11, so that the booster moving means I Can be quickly attached to the cylinder member 2.

  Next, when the nutritional composition 1 is administered, first, the outlet portion of the nozzle 3 is fitted into the insertion portion 6 of the gastrostomy tube 5, for example. Then, by holding the handle 30 in a folded state and rotating the shaft center of the main body of the handle 30 to a position orthogonal to the axis of the cylinder member 2, the outer periphery of the fulcrum 31 of the handle 30 The first concave portion 35 a provided on the outer periphery of the cylinder member 2 is separated from the convex portion 34 provided on the outer periphery of the cylinder member 2, and the second concave portion 35 b provided on the outer periphery of the fulcrum portion 31 of the handle 30 is provided on the cylinder member 2. Since the handle 30 is engaged with the convex portion 34 provided on the outer periphery and fixed to a state protruding outward from the cylinder member 2, the handle 30 is supported by one hand and the second cap is supported by the other hand. The operation handle 25 of the booster moving means I provided on the member 8 is operated.

  The operation handle 25 can move the drive shaft 17 to the nozzle 3 side by repeatedly swinging left and right with the bearing portion 17 of the second cap member 8 as a fulcrum. That is, in FIG. 1, when the operation handle 25 is rotated to the right (counterclockwise), the locking member 27 is always subjected to a clockwise rotational force. The claw 28 gets over the slope of the locking groove 21 positioned in front of the first locking groove row 15 of the drive shaft 17 and then engages with the vertical surface of the locking groove 21 positioned rearward. Therefore, if the operating handle 25 is rotated to the left (clockwise) after the operating handle 25 has been rotated to the right (counterclockwise), the locking member 27 is always subjected to a clockwise rotational force. Therefore, the state in which the locking claw 28 of the locking member 27 is engaged with the vertical surface of the locking groove 21 is maintained, and the drive shaft 17 is moved to the nozzle 3 side by a predetermined distance. By repeating the operation of swinging left and right with the bearing portion 17 of the second cap member 8 of the operation handle 25 as a fulcrum as described above, the drive shaft 17 is moved toward the nozzle 3 by a predetermined distance. Finally, the front surface of the piston body 7 comes into contact with the inner wall of the first cap member 4 and the entire amount of the nutritional composition 1 is discharged from the nozzle 3 to the outside.

  In addition, the length of the first locking groove row 15 of the drive shaft 17 is formed in advance by a dimension that allows the entire amount of the nutritional composition 1 to be discharged from the nozzle 3 to the outside by the piston body 7. Even if the operation handle 25 is swung left and right more than necessary, the engagement groove 14 with which the engagement claw 20 of the engagement member 19 engages does not exist. As a result, the drive shaft 17 is moved further to the nozzle 3. It cannot be moved to the side. Thereby, even if the operation handle 25 is operated more than necessary, the drive shaft 17 does not move to the first cap member 4 side, and the piston body 7 does not destroy the first cap member 4.

  After the entire amount of the nutritional composition 1 is discharged from the nozzle 3 to the outside, the first cap member 4 is removed from the cylinder member 2 and the piston body 7 is taken out from the cylinder member 2 as shown in FIG. Become. As a result, immediately after the administration of the nutritional composition 1 is completed, the operation of taking out the piston body 7 from the cylinder member 2 by a continuous operation can be easily performed by machine operation. There is no trouble of manually taking out the piston body 7 that is being moved.

  In order to remove the piston body 7 from the cylinder member 2, the retaining member 12 provided on the drive shaft 17 is picked and the drive shaft 17 is rotated 180 ° so that the second locking groove row 16 locks the operation handle 18. The drive shaft 17 is further advanced by repeating the operation of swinging the operation handle 25 left and right after being able to engage with the locking claw 28 of the member 27. Then, the pressing member 18 provided at the front end of the drive shaft 17 moves the piston body 7 to the open end side (left side in the drawing), and finally the piston body 7 is pushed out from the cylinder member 2. .

  After the piston body 7 is taken out from the cylinder member 2, the second cap member 8 having the drive shaft boosting movement means I can be detached from the cylinder member 2 to be disassembled into all members. The member can be easily cleaned. If necessary, the member such as the drive shaft 17 and the operation handle 25 can be disassembled from the second cap member 8 so that cleaning can be performed in finer units.

  So far, the nutritional composition 1 has been described on the premise that it is directly stored in the cylinder member 2, but the present invention is not limited to this.

  FIG. 10 is an explanatory view showing a state in which the nutritional composition enclosed in the bag-like container of the nutritional composition administration device according to the embodiment of the present invention is used.

  In the example shown in FIG. 10, a pre-stored bag-like container 40 is used as the nutritional composition 1 which is a solidified, gelled or solified nutrient or liquid food. In this case, a discharge port 41 for the nutritional composition 1 may be provided in a part of the bag-like container 40, and the discharge port 41 may be provided with a closing plug 42 for blocking outside air.

  As an administration device for the nutritional composition 1, the cylinder member 2 can be obtained by providing a fitting portion 43 into which the discharge port 41 of the bag-like container 40 can be fitted at the inlet portion of the nozzle 3 of the first cap member 4. When accommodating the nutritional composition 1 in the container, the closure plug 42 of the discharge port 41 of the bag-like container 40 is removed, and the discharge port of the bag-like container 40 is inserted into the fitting portion 43 of the nozzle 3 of the first cap member 4. By fitting the first cap member 4 to the cylinder member 2 after fitting 41, the bag-like container 40 can be accommodated in the cylinder member 2. As a result, not only the cylinder member 2 but also other members and hands do not touch the nutrient composition 1 directly, so that it is not only hygienic, but it is disassembled and cleaned into each member after administration of the nutrient composition 1 You can save time and effort.

  Furthermore, by making the shape of the discharge port 41 of the bag-like container 40 the same as the nozzle 3 that is shaped to fit into the insertion portion 6 of the gastrostomy tube 5, the nozzle 3 of the first cap member 4 is made to be the same. It can be made unnecessary. In this case, it is sufficient that a through-hole through which the discharge port 41 of the bag-like container 40 having the same shape as the nozzle 3 can be opened at the center of the first cap member 4, and the nutritional composition 1 is the first. Since the cap member 4 is not touched, the trouble of cleaning the first cap member 4 can be saved.
