Description

  The present invention relates to a hand bath basin for immersing and washing a hand of a person to be bathed in a bathing bed in bath water.

Patients who are lying on the bed due to illness or disability cannot keep their hands clean because it is difficult to get up from the bed and wash their hands. It is necessary to receive care such as wiping and hand bathing. Here, in order to bathe the patient's hand, in general, a ready-made washbasin is used. However, in Patent Document 1 below, the edge of such a ready-made washbasin is partially deformed. Proposed hand-washing bowls have been proposed.
Utility model registration No. 3099481

  However, in the ready-made washbasin as described above, when the patient is taking a bath in the supine position, the hand cannot be sufficiently immersed in the bath water in the washbasin, the patient's shoulders and arms float, and the wrist joint ( There has been a problem that the wrist) hits the edge of the basin, which causes pain to the patient. In addition, when a patient is bathing both hands at the same time in the lateral position, the arm on the lower side cannot be sufficiently immersed in the bath water in the wash basin. The wrist joint and forearm of the arm hit the edge of the basin, causing pain for the patient.

  Furthermore, in the case of a ready-made washbasin and the hand-washing bowl described in Patent Document 1, a patient who is in a disease, disorder, or long-term bed is contracted or deformed to the shoulder joint, elbow joint, wrist joint, or finger due to waste atrophy. In this case, the normal range of motion of the joint is limited, so that it is difficult to sufficiently immerse one's hand in a wash basin and sufficiently immerse in bath water.

  Therefore, in such a case, the nurse or caregiver repeatedly rubs the bath water in the hand and adjusts the height of the wash basin by inserting a pillow or towel between the wash basin and the top of the bed. The position of the washbasin and the posture of the patient should be adjusted so that the patient can easily bathe, such as by lifting the washbasin by another caregiver or extending the patient's upper limb. There is also a problem that the work is extremely complicated for nurses and caregivers.

  In addition, mattresses and mattresses are laid on the bed, and these are flexible and unstable surfaces. Therefore, when the weight of the patient's forearm is applied to the edge of the basin placed on the bed, There is also a problem that the basin easily tilts and bath water in the basin spills out and wets the bed sheets and patient's nightclothes.

  Therefore, in order to solve the above-described problems, the present invention is to immerse the hand of the subject bathing in the bathing bed in bath water and wash the hand while the subject is in the lateral position. An object of the present invention is to provide a hand bath basin that can be easily immersed in bath water and can be stably installed and used even on an unstable bed.

  In order to achieve this object, the hand bath basin according to claim 1 has a bathtub space for storing bath water for immersing and washing the hand of the person to be bathed, and the hand is in a vertical posture and The bathtub space having a depth that can be accommodated up to the wrist joint portion with the fingers in the extended position, a bottom plate that closes the bottom of the bathtub space, and a peripheral wall that is connected to the bottom plate and surrounds the periphery of the bathtub space A container member provided with a plate, an opening formed above the bathtub space, and an insertion port for inserting a hand into the bathtub space, and a part of the upper end of the peripheral wall plate of the container member. And a pressing member that extends in a generally tongue-like shape further upward from the upper end of the peripheral wall plate and is formed in a wide plate shape in the lateral width direction of the container member.

  According to the handbath basin of claim 1, the container member is placed on the mattress or bed, which is the bed resting place of the person to be bathed, with the insertion port facing upward. It is placed so as to snuggle up to the part from the chest to the abdomen. Moreover, when the container member is installed in this way, the pressing member is brought into close contact with the chest surface or the abdominal surface which is the upper side of the chest or the abdomen in the transverse direction when the subject to be bathed is in the lateral position. . Then, when the subject to be bathed is in the lateral position, the upper arm hand takes a vertically oriented posture and is inserted into the bathtub space from the insertion port of the container member.

  By this insertion, the hand of the person to be bathed is accommodated in the bathtub space up to the wrist joint portion in the vertical orientation, and is immersed in the bath water stored in the bathtub space. Further, at this time, the holding member of the hand bath basin is sandwiched between the inner side surface of the forearm and the front chest surface or the front abdominal surface, which is inserted into the bathtub space by the subject in the lateral position. Then, by this pinching, the hand bath basin is held by the hand bath subject himself on the bed place. Moreover, the hand bathing operation for the person to be bathed is performed using bath water in the bathtub space by inserting both hands of the nurse or the caregiver into the bathtub space from the insertion port of the container member.

  The handbath basin according to claim 2 is the handbath basin according to claim 1, wherein the pressing member extends further upward from an upper end portion of the peripheral wall plate corresponding to a rear portion of the container member, When the container member is viewed from the side, the container member is formed in a substantially arc shape that is inclined upward toward the rear upper side of the container member and curved in a convex shape toward the upper front side of the container member.

  According to the handbath basin of this aspect, the pressing member is a plate-like body extending from the container member so as to be curved in a substantially arc shape. Or it can be made to fit (contact | adhere) to the chest surface or abdominal surface of one side of the abdominal diameter direction. Therefore, when the hand bathing subject is in a lateral position, when the upper arm hand is inserted into the bathtub space of the container member, the holding member is placed between the forearm inner surface and the front chest surface or the front abdominal surface of the arm. There is an effect that the hand bath basin is more easily held by the body of the subject of the hand bath himself / herself.

  In addition, when the container member with the insertion port facing upward is placed near the chest or abdomen of the hand-bathing subject in the lateral position, the shape of the pressing member is the chest or abdomen surface on the upper side in the transverse direction of the chest or abdomen. It is desirable that the shape of the pressing member be in line with the curved surface of the chest from the front chest to the side chest of the person subject to hand bathing, or the curved surface of the abdomen from the front to the side of the abdomen. A shape having a curved line is preferable.

  The handbath basin according to claim 3 is the handbath basin according to claim 1 or 2, wherein the peripheral wall plate of the container member corresponds to a front side portion of the container member when the container member is viewed in plan view. The radius of curvature of the peripheral wall plate corresponding to the rear portion of the container member is formed larger than the radius of curvature.

  According to the handbath basin of claim 3, the peripheral wall plate of the container member has a larger curvature than the peripheral wall plate of the front portion when the container member is viewed in plan, and the peripheral wall plate of the rear portion is more The curvature is small and the shape is more flat. For this reason, there exists an effect that the outer surface of the rear side part of the peripheral wall board of a container member can be made to adhere more closely to the waist surface or abdominal surface of the subject who is in the side position.

  Further, since the curvature of the outer peripheral surface formed by the peripheral wall plate of the container member is locally different in this way, for example, according to the use situation of the hand bath basin and the body shape of the person to be bathed, There is also an effect that it is possible to select a portion of the peripheral wall plate having a curvature that easily fits the body of the person to be bathed and hit the body of the person to be bathed.

  In addition, when it is not necessary for the person to be hand bathed to pinch and fix the holding member, for example, in the position (Fahler position) or sitting position where the upper body is raised slightly, depending on the stage of illness, disability or health of the person to be hand bathed When hand bathing is performed, by changing the direction of the container member, the location of the peripheral wall plate of the container member that hits the body of the person subject to hand bathing is changed, and the peripheral wall plate in the front part of the container member, i.e., the curvature is There is an effect that a portion of the large peripheral wall plate can be brought into contact with the body of the subject to be hand bathed.

  The handbath basin according to claim 4 is the handbath basin according to any one of claims 1 to 3, wherein the container member is an upper end portion of the peripheral wall plate excluding a continuous formation portion of the pressing member. A curved edge plate portion that is bent outwardly from the container member and spreads in a substantially flare shape is formed, and the upper surface of the curved edge plate portion is formed substantially horizontally.

  According to the handbath basin according to claim 4, the upper edge of the peripheral wall plate of the container member is formed with a curved edge plate portion that is substantially flare-shaped, except for the continuous formation portion of the pressing member, Since the upper surface of the curved edge plate portion is formed substantially horizontally, even when a hand is inserted into the bathtub space from the insertion port, it is painful even if the outside of the forearm portion of the nurse or caregiver hits the curved edge plate portion of the container member. There is an effect that there is no sense of incongruity.

  In addition, the curved edge plate that spreads in a generally flare shape allows the nurse or caregiver to apply the weight of his / her forearm during hand bathing as long as the container member does not fall down. There is also an effect that the fatigue that a person feels at the time of hand bathing can be reduced. In addition, since the fingertip can be hooked on the curved edge plate portion of the container member, the curved edge plate portion can also be used as a handle for lifting the container member, and bath water is stored in the bathtub space. There is an effect that it can be easily lifted when lifting.

  According to the handbath basin of the present invention, the forearm portion of the upper arm when the handbath subject is in the lateral position, particularly when the handbath subject is in the lateral position. Is inserted so as to hang down into the container member, the hand naturally takes a vertical posture, and the hand can be accommodated in the bathtub space of the container member in this vertical posture. Therefore, there is no need for the person subject to hand bath to bend the wrist joint part, elbow joint part or shoulder joint part and insert his hand into the container member, and the pain of the person subject to hand bathing can be eliminated. There is.

  In addition, as described above, the hand of the person to be bathed is inserted into the bathtub space in a vertical posture, so that the wrist joint and forearm of the arm of the person to be bathed do not easily hit the upper end of the peripheral wall plate of the container member. There is an effect that it is possible to further eliminate the pain at the time of hand bathing of the person taking the bath.

  In addition, the bathtub space in which bath water for hand bathing is stored has a depth sufficient to accommodate a hand in a vertical orientation up to the wrist joint with the fingers extended, and this depth is a ready-made wash surface. It is very large compared to the depth of the vessel. For this reason, when washing hands in bath water by immersing hands in bath water, nurses and caregivers can wash their hands smoothly, and bath water is frequently discharged outside the container member. By preventing jumping and jumping out, there is an effect that it is possible to prevent soiling of a mattress or a bed sheet which is a place where a person is bathing in a hand bath.

  In addition, when the person to be hand bathed is in the lateral position, when the hand of the upper arm is inserted into the bath space of the hand bath basin, the hand bath basin is formed between the forearm inner surface and the front chest surface or front abdomen surface of the arm. By sandwiching the pressing member, the hand bath basin can be held by the body of the subject of the hand bath, and as a result, the hand bath basin can be stably installed even on an unstable mattress or bed. There is.

  Moreover, when the hand-bath subject in the lateral position inserts a hand into the bathtub space of the container member, most of the chest surface or abdomen surface of the hand-bath subject can be covered with the container member. In addition, since a generally tongue-shaped plate-shaped pressing member having a wide width extends further upward from the upper end portion of the peripheral wall plate of the container member, if this pressing member is included, the side bathing target The entire chest surface or abdominal surface of the person can be covered with the hand bath basin, and there is an effect that it is possible to prevent the nightclothes of the person to be bathed in the hand bath from being spoiled by the jumping of the bath water during the hand bath.

It is a front view which shows the use condition of the bath basin 1, FIG.12 (b) is a side view which shows the use condition of the hand bath basin 1. FIG.

  As shown in FIG. 1, the hand bath basin 1 is a hand bath container body mainly including a substantially bowl-shaped container member 2 and a substantially plate-shaped pressing member 3, for example, a synthetic resin material. It is integrally molded using materials such as. The container member 2 of the hand bath basin 1 is provided with a bath space 4 for storing bath water for immersing the hand 20 (see FIG. 12, the same applies hereinafter) of the person to be bathed in the bath. ing. This bathtub space 4 has a depth h <b> 1 that can accommodate the hand 20 of the person to be bathed up to the wrist joint in a vertically oriented posture with the fingers in the extended position.

  In addition, the depth h1 of the bathtub space 4 means the height from the inner bottom face of the container member 2 to the root of the curved edge portion. In addition, the meaning of the extended position of the finger does not necessarily include not only a state where the finger is fully extended but also a state where the extended finger is gently relaxed.

  In addition to the above-described bathtub space 4, the container member 2 has a bottom plate 5 (see FIG. 5) that closes the bottom of the bathtub space 4, and the bottom plate 5 integrally connected to the bottom plate 5. The peripheral wall board 6 which surrounds the circumference | surroundings and the insertion port 7 (refer FIG. 4) by which opening is formed above the bathtub space 4 and the hand 20 is inserted in the bathtub space 4 are provided.

  This insertion port 7 is an opening that communicates with the bathtub space 4, and not only the hand 20 of the person to be bathed but also the nurse or caregiver's hands (not shown) in the lateral direction of the container member 2 ( It can be inserted from both sides (in the left and right directions in FIGS. 2 and 4), and the nurse or the caregiver's hands are formed in such a size that can smoothly operate in the bathtub space 4 during cleaning.

  In addition, the curved edge plate portion 8 is integrally formed continuously at the upper end portion of the peripheral wall plate 6 of the container member 2 except for the portion where the pressing member 3 is continuously formed. The curved edge plate portion 8 is curved in a substantially arc shape toward the upper outer side of the container member 2 (see FIGS. 2, 3, and 6 to 9), and spreads in a generally flare shape as a whole. The upper surface 8a is formed substantially horizontally (see FIGS. 6 to 9).

  The container member 2 has a substantially similar shape in plan view (see FIG. 5) of the bottom plate 5 and opening shape of the insertion port 7 (see FIG. 4). Furthermore, the container member 2 has one cross-sectional shape (see FIG. 10) that is rounded at an arbitrary height position in the height h2 direction (the position of the XX line in FIG. 2), and an arbitrary different from that. The other cross-sectional shape (refer to FIG. 11) cut in a circle at the height position (the position of the XI-XI line in FIG. 2) is formed to be substantially similar to each other.

  Moreover, the container member 2 is formed such that the transverse area (or the diameter) of the bathtub space 4 gradually increases from the bottom plate 5 side to the insertion port 7 side of the container member 2, that is, from the bottom to the top. (See FIGS. 2 to 9). For this reason, the container member 2 of another handbath basin 1 can be inserted from the insertion port 7 of the container member 2 of the handbath basin 1, and a plurality of handbath basins 1 can be stacked in a stacked state.

  The hand bath basin 1 is set so that the position of its center of gravity is as close to the bottom side of the container member 2 as possible in consideration of stability when installed on a mattress or bed. For this reason, it is necessary to make the area of the bottom surface of the bottom plate 5 of the container member 2 as large as possible, and the area of the bottom surface of the bottom plate 5 cannot be made extremely small with respect to the opening area of the insertion port 7.

  Therefore, the container member 2 has a width w1 (see FIG. 8) of the bottom surface of the bottom plate 5 of approximately 80% to 95% (preferably approximately 85% to 90%) of the width w2 (see FIG. 8) of the insertion port 7. ), The depth width d1 (see FIG. 7) of the bottom surface of the bottom plate 5 is approximately 80% to 95% (preferably approximately 85% to 90%) of the depth width d2 (see FIG. 7) of the insertion slot 7. It is set to be in the range.

  Further, the peripheral wall plate 6 of the container member 2 has a larger curvature at the front side portion (lower side portion of FIGS. 10 and 11) of the peripheral wall plate 6 when the container member 2 is viewed in plan view. The rear portion of 6 (the upper portion in FIGS. 10 and 11) has a smaller curvature and a shape closer to a flat shape. For this reason, in particular, the outer surface of the rear portion (upper portion in FIGS. 10 and 11) of the peripheral wall plate 6 of the container member 2 is more easily brought into close contact with the lumbar surface or the abdominal surface of the hand bath subject who is in the lateral position. It has become.

  As shown in FIG. 3, the pressing member 3 is integrally connected to the upper end portion of the rear portion of the peripheral wall plate 6 having a small curvature and a substantially flat shape. As described above, the pressing member 3 is continuously formed at a part of the upper end portion of the peripheral wall plate 6 and further extends upward from the continuous portion. Further, as shown in FIG. 2, the pressing member 3 is formed in a generally tongue-like shape in a front view with a plate-like body that is wide in the lateral width direction (left and right direction in FIGS. 2 and 8) of the container member 2.

  In addition, the front side part of the surrounding wall board 6 means the part provided in the front side of the hand bath basin 1 among the surrounding wall boards 6, ie, the front part of the container member 2. FIG. Further, the rear side portion of the peripheral wall plate 6 means a portion provided on the back side of the hand bath basin 1 in the entire peripheral wall plate 6, that is, the back surface portion of the container member 2.

  Here, the back surface (rear surface) 3a of the pressing member 3 is applied to the abdominal surface from the chest surface of the hand-bath subject in the lateral position together with the outer surface of the rear portion of the peripheral wall plate 6 to which the pressing member 3 is connected. It is used in contact with the part surface (see FIG. 12B).

  Therefore, when the container member 2 is viewed from the side as shown in FIG. 6, the pressing member 3 extends further upward from the upper end portion of the peripheral wall plate 6 corresponding to the rear portion (left side in FIG. 6) of the container member 2. The container member 2 is inclined upward and upward toward the rear side (right diagonally upward in FIG. 6), and curved convexly toward the upper front side of the container member 2 (upward diagonally to the left in FIG. 6). It is formed in the substantially arc shape.

  In particular, the curved shape of the pressing member 3 is preferably a shape having a curve along the chest curved surface from the front chest to the side chest of the subject subject to hand bathing or the abdomen curved surface from the front abdomen to the side abdomen. . In this case, when the container member 2 with the insertion opening 7 facing upward is placed near the chest or abdomen of the hand-bath subject in the lateral position, the chest surface of the chest or abdomen on the lateral diameter upper side Or it becomes easy to fit abdominal surface.

  According to the hand bath basin 1 configured in this way, the bathtub space 4 of the container member 2 described above has a depth h1 that can accommodate the hand 20 in the vertical orientation up to the wrist joint portion. The height h2 of the container member 2 having the inside is approximately about 2/3 to 4/5 of the lateral diameter of the chest or abdomen of the subject subject to hand bathing. Therefore, as shown in FIG. 12 (a), when a person in hand-rest position in the lateral position inserts the hand 20 into the bathtub space 4 of the container member 2, most of the chest surface or abdominal surface of the hand-bath subject person is removed. And can be covered by the container member 2.

  Further, since the pressing member 3 is further extended upward from the upper end portion of the peripheral wall plate 6 of the container member 2, the height from the bottom surface of the bottom plate 5 of the container member 2 to the upper end of the pressing member 3 (hereinafter “ It is referred to as “the total height of the hand bath basin 1”.) H can be approximately equal to the chest lateral diameter or the abdominal lateral diameter of the subject subject to hand bath. That is, the overall height H of the hand bath basin 1 can be set to a size suitable for the chest or abdomen lateral diameter of the hand bath subject.

  In this case, as shown in FIG. 12 (a), when hand bathing is performed using the hand bath basin 1, the chest surface or abdominal surface of the subject subject to hand bathing in the recumbent position is entirely covered by the hand bath basin 1. It is possible to cover, and it is possible to prevent the nightclothes of the person to be hand bathed from being soiled by the jumping of the bath water during hand bathing.

  Next, with respect to the above-described hand bath basin 1, specific dimensions in the case where the person to be hand bathed is a man or a woman who is in a long-term bedridden (bedridden) state in the elderly will be exemplified. In addition, the values of the chest lateral diameter, abdominal lateral diameter, and third finger length of elder lies men & females described later are “Human body dimensions data for design”. This is a reference to “ergonomic design”.

  First, the total height H of the hand bath basin 1 is preferably about 25 cm. This value is a value calculated by subtracting approximately 5 cm from approximately 30 cm corresponding to approximately 95% ile value of the chest and abdomen lateral diameters of healthy elderly men and women (Elder lies Men & Female). Here, the decrease from about 30 cm to about 5 cm is because, for example, the subject undergoing hand bathing has systemic bone atrophy, muscle atrophy and fat loss due to aging and disuse atrophy, a decrease in height and weight, and a decrease in body volume. It takes into account the reduction and the forward or backward leaning posture due to the lateral position during hand bathing.

  Further, the depth h1 of the bathtub space 4 is preferably about 18 cm. This value is a value calculated by subtracting approximately 1.5 cm from approximately 19.5 cm corresponding to the approximately 95% ile value of the third finger length of elder men and women. Here, the reduction of about 1.5 cm from the above-mentioned 19.5 cm is that when the hand 20 is put into the bathtub space 4 of the hand bath basin 1 in a vertical posture, the fingers atrophy, etc. This is because the bath depth required for immersing the wrist joint in the bath bath in the relaxed and relaxed position is necessary.

  The lateral width w2 of the insertion port 7 of the container member 2 is preferably about 26 cm, and the depth width d2 of the insertion port 7 of the container member 2 is preferably about 18 cm. Furthermore, in the present embodiment, the depth width d1 of the bottom surface of the bottom plate 5 is in the range of about 80% to 95% (preferably about 85% to 90%) of the lateral width w2 of the insertion port 7 in the width w1 of the bottom surface of the bottom plate 5. Since the width is set to be in the range of approximately 80% to 95% (preferably approximately 85% to 90%) of the depth width d2 of the insertion port 7, the lateral width w1 of the bottom surface of the container member 2 is preferably approximately 23 cm. The depth width d1 of the bottom plate 5 of the container member 2 is preferably about 16 cm.

  Those who are in various developmental stages and health stages, such as those who are resting due to acute illness in adolescence or middle age, and those who are in the terminal stage without paralysis or contracture even in the elderly. In consideration of this, a plurality of types of hand bath basins 1 having dimensions corresponding to the body shape may be prepared for each body shape of persons having different developmental stages or health stages.

  Next, with reference to FIG. 12, the usage method of the hand bath basin 1 comprised as mentioned above is demonstrated. First, as shown in FIG. 12 (a), when installing the handbath basin 1 near the person in the hand-rest position, the container member 2 is placed with the insertion port 7 of the container member 2 facing upward. It is installed on a mattress or bed, which is the bedridden location of the person to be bathed, so as to snuggle up to the region from the chest to the abdomen of the person to be bathed in the lying position.

  At this time, as shown in FIG. 12B, the pressing member 3 is placed on the chest surface or the abdominal surface that is the upper side in the horizontal direction of the chest or the abdomen when the subject to be bathed is in the lateral position. Close (close). Then, if a person in the hand-rest position in the lateral position inserts the forearm portion 21 of the upper arm so as to hang down into the container member 2, the hand 20 naturally assumes a vertical posture and remains in this vertical posture. The hand 20 is accommodated in the bathtub space 4 of the container member 2.

  Then, as shown in FIG. 12A, the hand 20 of the person to be bathed is accommodated in the bathtub space 4 up to the wrist joint portion in the vertical orientation and immersed in the bath water stored in the bathtub space 4. Is done. At this time, the pressing member 3 of the hand bath basin 1 is sandwiched and fixed between the inner side surface of the forearm portion 21 and the front chest surface or the front abdomen surface inserted into the bathtub space 4.

  By this pinching, the hand bath basin 1 is held by the person himself / herself on the bed place and is stably installed even on an unstable mattress or bed. Thereafter, both hands of the nurse or the caregiver are inserted into the bathtub space 4 from the insertion port 7 of the container member 2, and the hand 20 of the person to be bathed is washed in the bathtub space 4 using bath water. Is called.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, you may make it provide the scale which shows the amount of bath water stored in the bathtub space 4 in the internal peripheral surface of the container member 2 of a present Example. Moreover, when the patient's one hand 20 and the nurse or caregiver's hands are inserted into the bathtub space 4, the container member 2 is placed so that the water level of the bath water becomes a level suitable for cleaning in the bathtub space 4. You may make it provide the mark which shows the appropriate water level of bath water on an internal peripheral surface. Alternatively, a hook may be attached to the upper portion of the pressing member 3, and the hand bath basin 1 may be hooked to a storage place such as a bedside or a washroom with the hook.

  In addition, when it is not necessary for the person to be hand bathed to hold the pressing member 3 and fix it, for example, depending on the stage of illness, disability, or health of the person to be hand bathed, the position of the upper body slightly raised (Fahler position) or sitting position When hand bathing is performed, the position of the peripheral wall plate 6 of the container member 2 that contacts the body of the person subject to hand bathing is changed by changing the direction of the container member 2 of the hand bath basin 1, and the front side of the container member 2 You may make it contact the part of the surrounding wall board 6 in a part, ie, the part of the surrounding wall board 6 with a large curvature, on a hand bath subject's body.

  Then, since at least the forearm portion 21 and the wrist joint portion of the hand bath subject can be supported by the curved edge plate portion 8 that is curved at the upper end of the peripheral wall plate 6 of the container member 2, A sense of incongruity and pain associated with the contact of the peripheral wall plate 6 can be avoided.
