Description

  The present invention relates to a bathing apparatus for nursing care for bathing a caregiver such as a bedridden elderly person or a physically handicapped person.

  Conventionally, after carrying a stretcher carrying a caregiver such as a bedridden elderly person or a physically handicapped person on a stretcher and laying it on the bathtub, only the stretcher is moved above the support in the bathtub. A bathing apparatus for nursing care is known in which a bathtub is raised by an elevating mechanism and a person being assisted is immersed in bath water to bathe (see, for example, Patent Document 1).

  In a welfare facility where such a bathing apparatus is installed, since a large number of caregivers are used for bathing every day, a chemical solution such as an aqueous sodium hypochlorite solution is supplied from a chemical injection device attached to the bathing apparatus. It is sterilized by injecting it into the bath water so that it has a predetermined concentration, and hygiene management of the bath water is performed.

  The chemical injection device of Patent Document 1 injects a chemical into the bathtub so that the concentration of the chemical in the bath becomes a set concentration based on the amount of hot water supplied to the bathtub or the amount of hot water measured by a flow sensor provided in the hot water supply pipe. It is configured. However, the residual chlorine concentration remaining in the bath water after the chemical solution is injected reacts with the organic matter derived from the skin of the person being assisted and the remaining residue of the cleaning agent attached to the bathtub, and the vitality disappears. Under the influence of various factors such as repeated bathing by the person, the chemical concentration set to a predetermined concentration at the start of bathing also gradually decreases with the passage of bathing time.

  In addition, since the decrease in the chemical concentration due to bathing the person being assisted is not taken into account, for example, after several persons have been bathed, the concentration of the chemical in the bath actually becomes extremely low. In many cases, a sufficient bactericidal effect is not obtained. In the bathing device of Patent Document 1, unless a hot water supply or a refilling hot water is supplied to the bathtub, the chemical solution injection device cannot be operated to inject the chemical solution, and after a predetermined number of baths or bathing time, the assistant However, there was a problem that even if there was a time when it was desired to replenish the chemical solution, it could not be replenished as expected, and the chemical concentration of the bath water could not be properly maintained at each welfare facility.

  On the other hand, in Patent Document 2, a hot water detection unit that detects the chemical concentration of the stored bath water is provided, and feedback control of the stored bath water chemical concentration is performed, thereby reducing the concentration of the chemical solution due to the consumption / deterioration of the chemical solution. A bathing apparatus is described in which a chemical solution is replenished and mixed in the stored bath water, and the chemical concentration of the bath water is maintained and restored to a control concentration that can effectively maintain the bath concentration.

Japanese Patent No. 3002181 JP 2002-325817 A

  However, in order to perform this feedback control, it is necessary to add a large-scale device such as a hot water detector or a control device to the bathing device, which not only increases the size of the bathing device but also increases the cost. Therefore, there has been a demand for the development of a bathing apparatus that can appropriately maintain and manage the chemical concentration of bath water with an inexpensive configuration.

  The present invention has been made in view of the above, and it is possible to appropriately maintain and manage the chemical concentration of the bath water while being excellent in convenience by enabling the injection of the chemical solution regardless of the hot water supply or the refilling water to the bathtub, Moreover, it is an object to provide a bathing apparatus that does not increase in size and cost.

  The bathing apparatus according to claim 1 is a nursing bathing apparatus for bathing a person being assisted in a bathtub, and a liquid injector for injecting a drug night into the bathtub, and a control unit for controlling the liquid injector. The control unit is capable of injecting a chemical solution from the chemical solution injection device when detecting that the number of bathing times or the bathing time in the bathtub has reached a predetermined threshold value.

  According to claim 1, since it is possible to inject a chemical liquid when it is detected that the number of bathing times or bathing time has reached a predetermined threshold even if hot water is not supplied to the bathtub or no additional hot water is added, It is possible to prevent a decrease in the concentration of the chemical solution with the lapse of time and the bathing time, and to appropriately maintain and manage the concentration of the bath water. In addition, there is no need to add a bath water concentration detection device or feedback control device to inject the chemical solution concentration, so the bathing device does not increase in size, and the conventional bathing device size can be maintained. As a result, the cost is not significantly increased and it is economical. Automating chemical injection can reduce the burden on the caregiver and prevent forgetting to operate.

  The invention according to claim 2 further includes a threshold changing operation unit that enables the predetermined threshold to be changed, and the control unit receives the predetermined threshold changing operation from the threshold changing operation unit. A change in the threshold value is accepted.

  According to the second aspect, the concentration of the chemical solution can be managed by freely setting the threshold of the number of bathing times or bathing time in consideration of the bathing situation in each welfare facility. In addition, when zero is set as the threshold value for the number of bathing times, the chemical solution can be injected flexibly without being restricted by the number of bathing times. Similarly, when zero time is set as the threshold for bathing time, the chemical liquid injection can be performed flexibly without being restricted by the chemical liquid injection by the bathing time.

  The invention according to claim 3 further includes an operation instructing unit for an assistant to instruct the operation of the chemical liquid injector, and the control unit receives an input from the operation instructing unit, and the bathing into the bathtub When it is detected that the number of times or the bathing time has reached a predetermined threshold, it is possible to inject a chemical solution from the chemical solution injection device.

  According to the third aspect, the assistant can instruct the operation of the chemical liquid injector via the operation instruction means. Moreover, it can prevent that a helper inject | pours a chemical | medical solution more than necessary and the chemical | medical solution concentration in bath water becomes too high.

  The invention described in claim 4 is characterized in that the operation instructing means is a chemical solution injection operation section.

  According to claim 4, since it is possible to instruct chemical injection by a simple operation of operating a chemical injection operation unit composed of a switch or the like, even an assistant who is unfamiliar with the operation of the bathing device can easily perform the operation. There is no annoyance.

  The invention according to claim 5 is characterized in that the amount of the chemical liquid to be injected by the assistant can be arbitrarily selected or set.

  According to the fifth aspect, since the amount of the medicine injected by the assistant can be arbitrarily selected or set according to the bathing situation of each welfare facility, fine concentration management is possible.

  The invention according to claim 6 has bath water circulation means for circulating the bath water in the bathtub, and the liquid medicine is injected from the chemical liquid injection device when the person being assisted is in a non-bathing state and the bath room circulation means. It is made when bath water is circulated.

  According to the sixth aspect of the present invention, the person being assisted can take a bath by bathing the bath in which the concentration of the chemical solution is sufficiently uniform, and the person being assisted will not be immersed in the bath water having a high concentration of the solution. This is preferable when a caregiver or a caregiver who has weak skin and is sensitive is taking a bath.

  The invention described in claim 7 is characterized by comprising a display notifying means for displaying and / or notifying the number of bathing times or bathing time.

  According to the seventh aspect, the assistant can easily grasp the number of times of bathing or the time of bathing, and can save the trouble of separately counting the number of times of bathing and the time of bathing. Moreover, the assistant can confirm whether or not the injection of the chemical solution from the chemical solution injection device is possible by comparing with the set number of bathing times or bathing time (predetermined threshold value).

  In the present invention, the chemical solution can be injected regardless of hot water supply or refilling hot water in the bathtub, and it is excellent in convenience. Further, the chemical concentration of the bath water can be more appropriately maintained and managed, and the apparatus is not increased in size and cost. A bathing apparatus that does not increase can be provided.

In FIG. 1, the jet nozzle 32 is illustrated outside the bathtub 4, but this is shown in order to clearly illustrate the relationship among the jet nozzle 32, the air inlet 33, and the jet pump 34. As shown, the jet nozzle 32 is installed in the bathtub 4.

  When a later-described bathtub circulation operation unit 7g equipped on the operation panel 7 of the bathing apparatus 1 is pressed, the jet pump 34 starts to operate, and the bath water in the bathtub 4 is sucked from the hot water inlet 30 and the circulation pipe 31.

  With reference to FIG. 4, the main electrical structure in the bathing apparatus 1 of this embodiment is demonstrated. The control unit 40 is configured mainly with a microcomputer, and is configured to execute the chemical solution injection flowcharts of FIGS. 5 and 6.

  From the chemical liquid injection operation unit 7e, the threshold value change operation unit 7f, the bath water circulation operation unit 7g and the bath ascending / descending / stopping operation unit 7h, the control unit 40 operates from the bath bathing position sensor 15 and the bathing bath position sensor 14. In response to the sensor input and the timing input from the timer 41, the drive control of the jet flow generating device 27, the lifting mechanism 9 of the bathtub 4 and the drive control of the chemical injection pump 38 and the like can be performed according to the chemical injection flowchart. It has a function.

  5 is a flowchart for injecting the chemical solution in consideration of the number of bathing times, and FIG. 6 is a flowchart for injecting the chemical solution in consideration of the bathing time.

  The control unit 40 has a function of measuring the number of bathing times or the bathing time based on the input of the timer 41, the sensor input of the bathing bath position sensor 14 and the bathing bath position sensor 15, and the like. Further, the chemical liquid injection operation unit 7e of the operation panel 7 serves as an operation instruction means for instructing the operation of the chemical liquid injection device 35, and the control unit 40 operates the chemical liquid injection device 35 in response to the instruction input. The bath hot water circulation operation unit 7g of the operation panel 7 is operated to instruct the operation of the jet flow generating device 27, and the control unit 40 operates the jet flow generating device 27 in response to the operation input.

  That is, the bathing apparatus 1 counts the number of baths in the flowchart of FIG. 5 or the bathing time in the flowchart of FIG. 6, and permits the injection of the chemical liquid from the chemical liquid injection apparatus 35 when the counted value reaches a predetermined threshold value. Is.

  First, the chemical solution injection flowchart of FIG. 5 in which chemical solution injection is performed in consideration of the number of bathing times will be described. The control unit 40 controls the execution of this chemical solution injection flowchart.

  In step n1, the number of baths is counted. As for the number of bathing times, the bathtub 4 is in the lowered position and the sensor input of the bathtub withdrawal position sensor 15 is received, then the bathtub 4 is raised and the sensor input is received from the bathtub bathing position sensor 14, and the bathtub 4 is further lowered. When there is a sensor input from the bathtub leaving position sensor 15, the number of bathing is counted as one. However, even if the bathtub 4 is in the lowered position and there is a sensor input from the bathtub withdrawal position sensor 15 and the sensor input from the bathtub bathing position sensor 14, the bathtub 4 is lowered or raised, If there is no sensor input from the bathing position sensor 15, the number of bathing is not counted. When the number of bathing is counted once, the process proceeds to step n2. The number of bathing times is displayed on the bathing number display section 7i.

  The number of bathing times can be detected from the determination of the presence or absence of the stretcher 4 on the support base 6 based on the sensor input of the proximity sensor 6a provided on the upper surface of the support base 6, and the number of bathing times can be counted. A sensor for detecting the mechanical connection between the letcher 3 and the bathtub 4 is provided, and the number of bathing times can be counted based on the sensor input from the sensor.

  In step n2, it is determined whether the number of baths has reached a set number of baths, for example, three. When it is determined that the number of bathing times has reached the set number of bathing times (predetermined threshold), the process proceeds to step n3.

  In step n3, the injection of the chemical solution is waited. The chemical liquid is injected when the bath bathing position sensor 15 detects the position, that is, when the bathtub 4 is at the lower limit and the bather is in a non-bathing state. The jet generator 27 starts to operate simultaneously with the chemical injection.

  In step n4, the process returns to step n3 until there is a sensor input from the bathtub bathing position sensor 15, and if it is determined that there is a sensor input, the process proceeds to step n5.

  In step n5, it is determined whether or not there is a sensor input from the bathing position water level sensor 24. The chemical solution is not injected until the sensor input is received from the bathing position water level sensor 24, and the jet flow generating device 27 does not operate. When the bathing water amount after bathing is detected by the bathing position water level sensor 24 and within the range not detected by the overflow water level sensor 25, the bathing position is set concentration with respect to the bathing water amount at the water level up to the bathing position water level sensor 24. The chemical solution is injected from the chemical solution injection device 35 so as to be (for example, 1 ppm). When it is determined that there is a sensor input from the bathing position water level sensor 24, the process proceeds to step n6.

  In step n6, it is determined whether the chemical liquid injection operation unit 7e has been operated. If the operation of the chemical solution injection operation unit 7e is not performed, the chemical solution is not injected. If it is determined in step n6 that the chemical liquid injection operation unit (operation instruction means of the chemical liquid injection device 35) 7e has been operated, the process proceeds to step n7.

  In step n7, the injection of the chemical solution is started. The amount of the medicinal solution to be injected may be arbitrarily selected by the assistant on the operation panel 7. For example, it is selected from 0.5 ppm, 1 ppm, 1.5 ppm, and 2 ppm. Alternatively, the assistant may increase or decrease the concentration on the operation panel so that the concentration can be freely set between 0.5 and 2 ppm. In addition, when chemical | medical solution injection | pouring is started, the frequency | count of bathing counted so far is reset.

  In step n8, the injection of the chemical solution is stopped. In addition, it is desirable to set the number of bathing times after measuring the tendency of the chemical concentration that decreases with the number of bathing times in advance in consideration of the bathing situation at each welfare facility. The set number of baths may be changed via the threshold value changing operation unit 7f. It is also possible to set zero as the set number of baths. When zero is set, the chemical solution can be injected as long as the conditions other than the number of baths are satisfied, and this is effective when it is desired to inject the chemical solution flexibly without being restricted by the number of baths.

  If the number of bathing times in the bathtub 4 reaches the set number of bathing times (predetermined threshold value) even if no hot water or hot water is added to the bathtub 4 by the execution of the flowchart of FIG. 7e can be operated to inject the chemical solution, so that it is possible to prevent a decrease in the chemical solution concentration due to repeated bathing, and to appropriately maintain and manage the bath water concentration. Further, since it is not necessary to add a bath water concentration detection device or a feedback control device for injecting the chemical solution, the bath device 1 is not increased in size, and the size of the conventional bath device 1 can be maintained. Compared to this, the cost is not significantly increased and it is economical.

  Next, the chemical solution injection flowchart of FIG. 6 in which the chemical solution is injected in consideration of the bathing time will be described. The control unit 40 controls the execution of this flowchart.

  In step n9, the timer 41 waits for a bathing time counting operation.

  In step n10, it is determined whether or not there is a sensor input from the bathtub bathing position sensor 14. When it is determined that there is a sensor input from the bathtub bathing position sensor 14, the process proceeds to step n <b> 11 because it is bathing in the bathtub 4.

  In step n11, the bathing time during the bathing is counted. When the bathtub 4 descends to a predetermined lower limit position and there is a sensor input from the bathtub bathing position sensor 15, the bathing time count is stopped. The control unit 40 accumulates this bathing time. The bathing time is displayed on the bathing time display section 7b.

  In step n12, it is determined whether or not the accumulated time of bathing time has reached the set bathing time (predetermined threshold). This set bathing time is, for example, 20 minutes.

  If it is determined in step n12 that the total bathing time has reached the set bathing time, the process proceeds to step n13.

  In step n13, the injection of the chemical solution is waited. The chemical liquid is injected when the bath bathing position sensor 15 detects the position, that is, when the bathtub 4 is at the lower limit and the bather is in a non-bathing state. In addition, when chemical | medical solution injection | pouring is started, the accumulated bathing time until now will be reset.

  In step n14, the process returns to step n13 until there is a sensor input from the bathtub bathing position sensor 15. When it is determined that there is a sensor input from the bathtub retreat position sensor 15, the process proceeds to Step n15 assuming that the bathtub 4 is in the lowered position.

  In step n15, it is determined whether or not there is a sensor input from the bathing position water level sensor 24. If it is determined that there is a sensor input from the bathing position water level sensor 24, the process proceeds to step n16 assuming that the bathtub 4 is in the lowered position and that there is an amount of bath water necessary for injecting the chemical in the bathtub 4.

  In step n16, it is determined whether or not the chemical liquid injection operation unit 7e has been operated. If the operation of the chemical solution injection operation unit 7e is not performed, the chemical solution is not injected. If it is determined in step n6 that the chemical liquid injection operation unit 7e has been operated, the process proceeds to step n17.

  In step n17, the injection of the chemical solution is started. The injection amount of the chemical solution is the same as that in the flowchart of FIG.

  In step n18, the injection of the chemical solution is stopped. In addition, it is desirable to set the set bathing time after measuring the tendency of the chemical concentration that decreases with the bathing time in advance in consideration of the bathing situation in each welfare facility. The set bathing time may be changed via the threshold value changing operation unit 7f. It is also possible to set zero minutes as the set bathing time. When zero is set, the chemical solution can be injected if the conditions other than the bathing time are satisfied, which is effective when it is desired to inject the chemical solution flexibly without being restricted by the bathing time.

  If the bathing time to the bathtub 4 reaches the set time (predetermined threshold value) even if no hot water or hot water is supplied to the bathtub 4 by the execution of the flowchart in FIG. Since it is possible to inject the chemical liquid by operating, it is possible to prevent the chemical liquid concentration from decreasing due to repeated bathing, and to appropriately maintain and manage the bath water concentration. Further, since it is not necessary to add a bath water concentration detection device or a feedback control device for injecting the chemical solution, the bath device 1 is not increased in size, and the size of the conventional bath device 1 can be maintained. Compared to this, the cost is not significantly increased and it is economical.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, A various change is possible within the range which does not deviate from the meaning.
For example, in the present embodiment, the bathing device has no hot water storage tank, but the hot water storage tank is provided, and the bathing device that moves hot water between the hot water storage tank and the bathtub adopts a chemical solution injection configuration that takes into account the number of bathing times. May be. In this case, the number of times of opening / closing the bathtub door and the number of times of movement of the bath water are counted as the number of bathing times, and the same thing as the flowchart of FIG. 5 can be executed.

  Moreover, in this embodiment, although the bathtub 4 was a raising / lowering type, it is applicable also to a fixed bathtub. For example, a combination of a fixed bathtub and an elevating stretcher having a placement portion on which a bather can be placed may be used. In this case, for example, a sensor for detecting the upper limit position of the placement unit (hereinafter referred to as an upper limit position sensor) on the liftable stretcher and the bathing position is detected when the placement unit descends into the bath and becomes the bathing position. Sensors (hereinafter referred to as bathing position sensors) are provided. The number of times of bathing is determined from the bathing position sensor when the placing part of the liftable stretcher is at the upper limit position and there is an input from the upper limit position sensor and then the placing part descends into the bathtub and enters the bathing position. In addition, once bathing is completed and the placement unit is raised to the upper limit position and there is an upper limit position sensor input, it can be counted as one time. This bathing frequency information is transmitted to the fixed tub by wireless or other remote information transmission means, and when the predetermined conditions including the bathing frequency condition are satisfied on the fixed tub side, the chemical liquid injection from the chemical liquid injection device is enabled. Can do.

  On the other hand, the bathing time is input from the upper limit position sensor, then the placement unit descends to the bathing position, and when there is an input from the bathing position sensor, the bathing time starts counting, the bathing ends and the placement unit When it rises and there is an input from the upper limit position sensor again, the counting of the bathing time can be ended.

  Moreover, in this embodiment, although the stretcher is a raising / lowering type, it can be applied to a bathing apparatus comprising a combination of a raising / lowering bathtub and a fixed stretcher.

  Further, as disclosed in the prior art, based on the amount of hot water supplied to the bathtub or the amount of hot water measured by the flow sensor interposed in the hot water supply pipe, the chemical concentration in the bathing area is set to the set concentration so that the bath has a chemical concentration. A configuration for injecting a chemical solution can be added to the present invention, and a bathing system can be configured so that the conventional configuration and the present invention can be used together.

  In the present embodiment, the chemical solution injection operation unit 7e of the operation panel 7 is operated to instruct the injection of the chemical solution. However, the number of bathing times or the bathing time is set to a predetermined threshold without instructing the injection of the chemical solution. Then, only the set chemical solution concentration may be automatically added.

  Moreover, in this embodiment, although the bathing frequency display part 7i and the bathing time display part 7b provided in the operation panel 7 were demonstrated as an example of a display alerting | reporting means, it is not limited to this, The timing which the bathtub 4 descend | falls You may comprise so that it may announce to a helper by the voice etc. and the number of bathing and bathing time (at the time of bathing).
