Description

[Technical field]

[0001] The present invention relates to a manual aspirator that is effective for removing nasal mucus from people who have difficulty blowing their clogged nose by themselves, such as babies. [Background technology]

[0002] For example, in the case of babies who are unable to blow their own noses, a nasal mucus suction device is used in which the nasal mucus is sucked up through a nasal suction nozzle connected to an aspirator by activating the aspirator. As such nasal mucus suction devices, those using a motor-driven aspirator (Patent Documents 1 to 3) and those using a manually-driven aspirator (Patent Document 4) are already known.

[0003] As shown in FIGS. 14 and 15, the nasal mucus suction device 100 described in Patent Document 4 includes a manual aspirator 200, a nasal mucus suction nozzle 300, and an intake tube 400.

[0004] As shown in Figures 13 and 14, the manual aspirator 200 is biased toward the suction nozzle 210 by a coil spring 530, and is provided with a piston portion 520 that provides an airtight partition between the portion of the cylinder portion 201 that houses the coil spring 530 and the tube connection nozzle 210. The nasal mucus suction nozzle 300 includes a suction tube 310, a tube connection nozzle 320, and a nasal mucus reservoir 330. One end of the suction tube 400 is connected to the tube connection nozzle 210 of the manual aspirator 200 , and the other end is fitted to the tube connection nozzle 320 of the nasal mucus suction nozzle 300 .

[0005] As shown in Figure 13, in this manual aspirator 200, by manually pulling the handle 510, which is the manual force application part, in the direction of the arrow in Figure 13, the piston part 520 is moved via the piston rod 511 to the opposite side to the suction nozzle 210 against the biasing force of the coil spring 530, thereby creating negative pressure between the suction nozzle 210 of the cylinder barrel part 201 and the piston part 520.

[0006] On the other hand, when the handle 510 is released, the piston portion 520 returns to its original position shown in FIG. In Figures 14 and 15, 220 and 230 are check valves.

[0007] That is, the above-mentioned manual nasal mucus sucker 100 is configured as described above, and with the tip of the nasal mucus suction nozzle 300 inserted into the nostrils of a baby or the like, by manually pulling the handle 510 of the aspirator 200 as shown in FIG. 13, the pressure inside the nasal collection section 330 of the nasal mucus suction nozzle 300 is reduced, and nasal mucus is sucked from the suction tube section 310 into the nasal mucus collection section 330. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 6831542 [Patent Document 2] Patent No. 6959843 [Patent Document 3] JP 2022-13264 A [Patent Document 4] Registered Utility Model No. 3233144 Summary of the Invention [Problem to be solved by the invention]

[0009] However, when the above-mentioned manual aspirator 200 is used in the nasal mucus aspirator 100, the following problems arise. That is, babies with stuffy noses are often unwell, fussy and unable to keep their head still.

[0010] In such a case, the user must hold the baby and place the nasal mucus suction nozzle 300 against the nose while restricting the movement of the baby's head, which means that both hands are occupied and the user cannot operate the handle 510 by himself. Therefore, in the case of the nasal mucus suction device 100, it may be difficult to use it when there is no one to help, such as a family member.

[0011] In view of the above circumstances, the present invention aims to provide a manual aspirator that can easily perform suction operation by one person, and a nasal mucus suction device using the manual aspirator that enables even a subject that is not still, such as a baby, to easily aspirate nasal mucus by manual operation by one person. [Means for solving the problem]

[0012] In order to achieve the above object, the manual aspirator of the present invention comprises a cylinder portion, a piston portion capable of moving back and forth within the cylinder portion in the direction of its cylinder axis while the inside of the cylinder portion is partitioned airtight, a lid portion for closing one end of the cylinder portion, biasing means for biasing the piston portion toward the lid portion, a connecting rod having one end connected to the piston portion and a manual force applying portion connected to the other end of the connecting rod, and when an operator applies a force against the biasing force of the biasing means to the manual force applying portion by manual force, the piston portion is slidable in a direction away from the lid portion, and the lid portion or the cylinder portion is connected to the inside of the cylinder portion, and when the piston portion slides in a direction away from the lid portion, the manual aspirator is equipped with a suction nozzle which is capable of sucking from outside the cylinder portion, ,before a support part capable of supporting the cylinder part in a position in which the lid part side faces upward, and a pedal part which is stepped on by an operator's foot with the force application part supported in the position in which the lid part side faces upward, to slide the piston part in a direction away from the lid part. The pedal portion is pivotally supported by the connecting rod so as to be selectable between a stepped-down use position and a folded position in which one of the upper and lower surfaces of the pedal portion is aligned with a side wall of the connecting rod, and the base portion is pivotally supported by the lower end of the support column so as to be selectable between a cylinder tube portion support position and a folded position in which one of the upper and lower surfaces of the base portion is aligned with the connecting rod. It is characterized by the following.

[0013] The manual aspirator of the present invention is not particularly limited, but may be: A pair of the support pillars are provided so as to rise in parallel from the base portion, and the pedal portion is disposed so as to slide between the pair of the support pillars. It can be configured as follows. In other words, with the above-mentioned configuration, when the operator of the manual suction device steps on the pedal portion to perform the suction action, the support portion can support the load in a balanced manner, and the posture of the cylinder portion can be stably maintained.

[0015] Although not particularly limited, the manual aspirator of the present invention is preferably arranged so that the folding position of the pedal portion and the folding position of the base portion sandwich the connecting rod. That is, with the above-mentioned configuration, the manual aspirator can be stored more compactly.

[0016] Although not particularly limited, the manual suction device of the present invention preferably has a handhold recess on the cylinder portion side for manually applying force to the pedal portion when the pedal portion is in the folded position. That is, with the above-mentioned configuration, the suction action of the force application part can be easily performed by hand. Effect of the Invention

[0018] As described above, the manual aspirator of the present invention comprises a cylinder portion, a piston portion capable of moving back and forth within the cylinder portion in the direction of its cylinder axis while the inside of the cylinder portion is airtightly partitioned, a lid portion for closing one end of the cylinder portion, biasing means for biasing the piston portion toward the lid portion, a connecting rod having one end connected to the piston portion and a manual force application portion connected to the other end of the connecting rod, and when an operator applies a force against the biasing force of the biasing means to the manual force application portion by manual force, the piston portion is slidable in a direction away from the lid portion, and the lid portion or the cylinder portion is connected to the inside of the cylinder portion, and when the piston portion slides in a direction away from the lid portion, the manual aspirator is equipped with a suction nozzle that is capable of sucking from outside the cylinder portion, and further comprises a base portion supported on an installation surface of the manual aspirator, and a suction nozzle extending from the base portion. ,beforea support part capable of supporting the cylinder part in a position in which the lid part side faces upward, and a pedal part which is stepped on by an operator's foot with the force application part supported in the position in which the lid part side faces upward, to slide the piston part in a direction away from the lid part. The pedal portion is pivotally supported by the connecting rod so as to be selectable between a stepped-down use position and a folded position in which one of the upper and lower surfaces of the pedal portion is aligned with a side wall of the connecting rod, and the base portion is pivotally supported by the lower end of the support column so as to be selectable between a cylinder tube portion support position and a folded position in which one of the upper and lower surfaces of the base portion is aligned with the connecting rod. This means you can operate the suction using only your feet, without using your hands. Therefore, the nasal mucus suction device, which has a nasal mucus suction nozzle connected to this manual aspirator, can be used, for example, to hold a baby in one hand with its face fixed, while holding the nasal mucus suction nozzle in the other hand and firmly fixing the tip of the nozzle to the baby's nostril. In other words, a person can easily suction a baby's nasal mucus by using his or her hands and feet. Moreover, the base portion can be made compact when storing the manual aspirator.

[0020] The present invention will now be described in detail with reference to the drawings showing embodiments thereof. FIG. 1 shows a first embodiment of a nasal mucus suction device according to the present invention.

[0021] As shown in FIG. 1, the nasal mucus suction device A includes a manual aspirator 1a, a nasal mucus suction nozzle 2a, and a suction tube 3a. The manual aspirator 1a includes an upper member 11, a lower member 12, and a piston member 13, as shown in FIGS.

[0022] The upper member 11 includes a cylinder portion 11a and a lid portion 11b, and also includes a suction nozzle 11c protruding from the center of the lid portion 11b. As shown in Figures 2 and 3, the lower member 12 includes a cup-shaped lower cover portion 12a that screws onto the outer periphery of the lower end of the cylinder portion 11a, a pair of support pillars 12b that support the lower cover portion 12a, and a base portion 12c that supports both support pillars 12b from below. The lower cover portion 12a has a bottom formed with an insertion hole 12d through which a connecting rod 13b that connects a piston portion 13c and a pedal portion 13a, which will be described later, is slidably inserted.

[0023] The piston member 13 includes a piston portion 13c, a pedal portion 13a as a force applying portion, and a connecting rod 13b connecting the piston portion 13c and the pedal portion 13a. The piston portion 13c hermetically separates the inside of the cylinder portion 11a by a seal ring 13f fitted slidably inside the cylinder portion 11a, and is provided with a check valve 13g as shown in FIG.

[0024] A coil spring 13d is fitted around the connecting rod 13b as a biasing means for biasing the piston portion 13c toward the cover portion 11b inside the cylinder portion 11a.

[0025] As shown in FIG. 4, the nasal mucus suction nozzle 2a includes a nostril insertion portion 21, a nasal mucus collecting portion 22, and a suction tube connecting portion . The nostril insertion portion 21 has a generally spindle-shaped cap shape in a side view, and is provided with a nasal mucus suction passage 21a that opens at the tip of the nostril insertion portion 21 along the central axis.

[0026] The nasal mucus collecting portion 22 is generally cylindrical and has an opening at the top and a bottom, and is provided with a ring-shaped fitting recess 22a on the side, and an air hole 22b is formed at the bottom of the fitting recess 22a. The lower end of the nostril insertion portion 21 is airtightly fitted into the upper end of the nasal mucus pool 22 so that the nasal mucus suction passage 21a faces the inside of the nasal mucus pool 22.

[0027] The suction tube connection part 23 includes a tube connection nozzle 23a and a check valve 24. The fitting part 23b is airtightly fitted into the fitting recess 22a, and the check valve 24 airtightly covers the air hole 22b except when suction is being performed. The suction tube 3a is made of a transparent or translucent flexible resin, one end of which is connected to the suction nozzle 11c of the manual aspirator 1a, and the other end of which is connected to the tube connection nozzle 23a of the nostril insertion portion 21.

[0028] This nasal mucus suction device A is configured as described above. By placing the base portion 12c on the floor (not shown) and supporting the manual aspirator 1a on the floor, when the pedal portion 13a is depressed with the foot, the piston portion 13c moves in a direction away from the suction nozzle 11c against the biasing force of the coil spring 13d via the connecting rod 13b, as shown in Figure 3. Then, the internal volume between the piston portion 13c and the lid portion 11b expands, and the inside of the cylinder portion 11a becomes in a reduced pressure state. In addition, by creating a reduced pressure state inside the cylinder portion 11a, the inside of the nasal mucus collection portion 22 of the nostril insertion portion 21, which is connected via the suction tube 3a, is also created in a reduced pressure state, making it possible to suction nasal mucus through the nasal mucus suction passage 21a.

[0029] On the other hand, when the foot stops pressing down on the pedal portion 13a, the piston portion 13c moves toward the suction nozzle 11c by the biasing force of the coil spring, as shown in FIG. At this time, the check valve 13g is bent to the valve opening side.

[0030] That is, as described above, in this nasal mucus suction device A, the manual aspirator 1a has a pedal portion 13a that can be operated with the foot, so that a single person can easily aspirate nasal mucus by holding the baby in one arm and supporting the baby's head with that hand to prevent it from moving, while using the other hand to hold the nostril insertion portion 21 of the nasal mucus suction nozzle 2a inserted into the baby's nostril and then stepping on the pedal portion 13a. In addition, the nasal mucus suction device A may be designed so that the pedal portion 13a is operated by hand.

[0031] 5 and 6 show modified examples of the nasal mucus suction nozzle. As shown in Figures 5 and 6, this nasal mucus suction nozzle 2b is similar to the above-mentioned nasal mucus suction nozzle 2a, except that the lower end of the nostril insertion portion 25 is screwed into the nasal mucus collection portion 26, and the female threaded cylindrical portion 27b of the suction tube connection portion 27 is screwed into the male threaded cylindrical portion 26a of the nasal mucus collection portion 26.

[0032] As described above, this nasal mucus suction nozzle 2b is configured such that the lower end of the nostril insertion portion 25 is screwed into the nasal mucus collection portion 26, and the female threaded tubular portion 27b of the suction tube connection portion 27 is screwed into the male threaded tubular portion 26a of the nasal mucus collection portion 26. Therefore, although assembly is slightly more complicated than with the nasal mucus suction nozzle 2a, the three components are firmly assembled. In addition, in FIG. 5 or FIG. 6, 28 is a check valve, and 25a is a nasal mucus suction passage.

[0033] 7 to 13 show a second embodiment of the manual aspirator of the present invention. As shown in Figures 7 and 8, in this manual aspirator 1b, a cover portion 14b that covers the upper end of the cylindrical portion 14a of the upper member 14 has a recess 14c in its center, and a suction nozzle 14d is provided at the bottom of this recess 14c, with its tip being of a length that almost coincides with the upper surface of the cover portion 14b, and the suction nozzle 14d does not protrude to the outside.

[0034] Similar to the lower member 12 of the first embodiment, the lower member 15 includes a cup-shaped lower cover portion 15a that screws onto the outer periphery of the lower end of the cylinder portion 14a, two support pillars 15b, a connecting portion 15c that connects the lower ends of the support pillars 15b, and a base portion 15d.

[0035] Base portion 15d has an approximately U-shape in plan view, with the upper end of the U-shape pivoted to the lower end of support portion 15b via a pivot shaft (not shown), allowing selection between a support position shown in FIG. 7 and a folding position in which it rotates approximately 270 degrees from this support position and the tip (the end opposite the pivot) fits beneath lower cover portion 15a of lower member 15, as shown in FIGS. 11 and 12. The pivot shaft is provided with knobs 15e at both ends. The knob portion 15e is fitted into a recess 15f provided on the side of the base portion 15d, and, although not shown, when the base portion 15d is rotated to a supporting position or a folding position, a positioning recess (or protrusion) provided on the peripheral surface of the knob portion 15e fits into a positioning protrusion (or recess) provided on the inner wall surface of the recess 15f and is positioned.

[0036] The piston member 16, like the piston member 13, includes a piston portion 16e, a connecting rod 16b, and a pedal portion 16a. As shown in Figs. 7, 9 and 11, the connecting rod 16b has finger hooks 16j at its lower end which extend to both sides in the width direction of the pedal portion 16b and on which fingers are hooked during manual operation as described later. The finger hook portion 16j has an end from which a pivot portion 16k for the pedal portion 16b extends. The pedal portion 16a is pivoted to a pivot portion 16k and can be selected around a pivot axis (not shown) between a stepping position in which the stepping surface 16d of the pedal portion 16a, as shown in Figures 7 and 8, is positioned approximately perpendicular to the axis of the connecting rod 16b, and a folded position as shown in Figures 11 and 12 in which the stepping surface 16d is approximately aligned with the connecting rod 16b and the tip of the pedal portion 16a faces the underside of the lower cover portion 15a from below.

[0037] The pivot shaft of the pedal portion 16a is provided with knob portions 16h on both ends. The knob portion 16h is fitted into a recess 16i provided in the pivot portion 16k of the connecting rod 16b, and, although not shown, when the pedal portion 16a is rotated to a position where it can be depressed or to a folded position, a positioning recess (or protrusion) provided on the peripheral surface of the knob portion 16h fits into a positioning protrusion (or recess) provided on the inner wall surface of the recess 16i and is positioned.

[0038] This manual suction device 1b is configured as described above. When the base portion 15d is in the support position as shown in Figures 7 and 8 and the pedal portion 16a is in the stepping position, and the pedal portion 16a is stepped on with the foot as shown in Figures 9 and 10, the piston portion 16f moves in a direction away from the lid portion 14b against the biasing force of the coil spring 16g, and the inside of the cylinder portion 14a between the piston portion 16f and the lid portion 14b is reduced in pressure, and air is sucked in through the suction nozzle 14d. Therefore, similarly to the above-mentioned manual aspirator 1a, by connecting the nasal mucus suction nozzle 2a to the suction nozzle 14d via the suction tube 3a, nasal mucus can be easily aspirated by a single person.

[0039] In addition, as shown in Figs. 11 and 12, the base portion 15d and the pedal portion 16a of the manual inhaler 1b can be folded, so that the manual inhaler 1b can be stored compactly. Furthermore, in this folded state, as shown in FIG. 12, the connecting rod 16b has at its lower end a finger hook 16j extending in the width direction of the pedal portion 16b. Therefore, for example, as shown by the chain line in FIG. 12, when viewed from the rear side, the palm of the right hand RH is pressed against the connecting portion 15c and supported by the thumb f1, the middle finger f3 is hooked on the left finger hook portion 16j and the ring finger f4 is hooked on the right finger hook portion 16j, and the index finger f2 is held along the left side surface of the base portion 15d and the little finger f5 is held along the right side surface of the base portion 15d, and the middle finger f3 and ring finger f4 are bent toward the palm, and as shown in FIG. 13, the connecting rod 16b slides in the direction of the arrow and the piston portion 16e slides away from the lid portion 14b via the connecting rod 16b, so that the suction action can be easily performed even by hand. In addition, in Figs. 8 to 13, 16c denotes a notch provided so that the tip of the pedal portion 16b fits neatly along the lower edge of the lower cover portion 15a when folded, and 16f denotes a seal ring.

[0040] The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the biasing means is a coil spring, but it may be an elastic member such as rubber or elastomer. In the above embodiment, a manual aspirator is used as the nasal mucus suction device, but the aspirator of the present invention can also be used for suctioning things other than nasal mucus. In the above second embodiment, the manual operation is performed with the right hand, but it may be performed with the left hand. [Explanation of symbols]
