Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a bedridden defecation care device. Background Art

[0002] The problem of defecation and urination for bedridden patients has always existed in clinical nursing. The conventional method is: after the patient expresses the need to defecate and urinate, the nursing staff will install the bedpan in the defecation and urination opening of the bed under the patient's buttocks. After the patient urinates or defecates, the nursing staff will take away the bedpan and clean up for the patient.

[0003] There are also lying toilets in the prior art, of different types, including lying toilets placed under the hospital bed. For reference, patent CN109172209B discloses an automatic lying toilet that assists defecation. The operation of this type of lying toilet is roughly as follows: when the patient switches it on by himself, the nursing staff switches it on, or the detection device detects the need for defecation, the toilet opening below the patient's buttocks on the bed opens, and the patient's excrement falls from the toilet opening into the collection device of the lying toilet. After the patient urinates or defecates, the path through which the excrement passes needs to be cleaned. However, as the use time increases, or because the excrement in the collection device fails to be transferred away in time, or because the path through which the excrement passes is not cleaned thoroughly, the odor at the lying toilet gradually increases, affecting the ward environment, and then affecting the patient's mood and treatment effect, which puts higher requirements on nursing.

[0062] See also Figures 1 to 10 This embodiment provides a bed defecation care device, including a frame 10, a support frame 20, a collection bag 30, a sealing mechanism 40 and a driving mechanism 50.

[0063] The frame 10 is arranged under the bed, and the frame 10 can be connected to the bed, and the frame 10 can also be moved under the bed by being installed on a cart. The support frame 20 is arranged on the frame 10, and the support frame 20 can be moved laterally and longitudinally to the bottom of the toilet opening 60 of the bed. The collection bag 30 is arranged on the support frame 20, and the collection bag 30 is used to receive the excrement falling from the toilet opening 60. The sealing mechanism 40 is arranged on the frame 10, and the sealing mechanism 40 is used to seal the collection bag 30. The driving mechanism 50 is used to drive the support frame 20 to move.

[0064] In this embodiment, the nursing staff stands on one side of the bed, and the support frame 20 is also located on the side below the bed. The nursing staff installs the collection bag 30 on the support frame 20. Driven by the driving mechanism 50, the support frame 20 moves horizontally to the bottom of the bed toilet opening 60, and then the support frame 20 rises, driving the collection bag 30 to approach the toilet opening 60.

[0065] After the patient urinates or defecates, when the nursing staff cleans the patient, the support frame 20 moves downward and moves horizontally to one side below the bed. At the same time, the sealing mechanism 40 seals the collection bag 30 to prevent the odor from emitting. The nursing staff then replaces the collection bag 30.

[0066] Compared with the existing reclining toilet, the present device collects the patient's excrement through the collecting bag 30, and there is no need to set up an additional cleaning structure to clean the path through which the excrement passes. In addition, the collecting bag 30 is sealed after being loaded with excrement, which can be conveniently taken away for disposal, reduce odor emission, improve the ward environment, benefit the patient's treatment, and reduce the difficulty of nursing.

[0067] In one embodiment, the frame 10 includes two symmetrically arranged mounting plates 11. The mounting plates 11 are provided with a first guide slot 12, the first guide slot 12 includes a first slot section 121 extending transversely and a second slot section 122 extending vertically, the lower end of the second slot section 122 is connected to the end of the first slot section 121.

[0068] The driving mechanism 50 includes two driving plates 51 and a first connecting square rod 53 .

[0069] The two drive plates 51 are symmetrically arranged, and the two drive plates 51 are located between the two mounting plates 11. The drive plates 51 are provided with second guide grooves 52 arranged obliquely, and the drive plates 51 can be arranged on the frame 10 to be movable in the horizontal direction. The first guide groove 12 and the second guide groove 52 can roughly form a "U" shape. Specifically, the upper and lower ends of the inner sides of the two mounting plates 11 respectively extend protrusions inward, and the upper and lower ends of the drive plates 51 slide and cooperate with the corresponding protrusions.

[0070] The two ends of the first connecting square rod 53 are respectively slidably matched with the corresponding first guide groove 12, and the first connecting square rod 53 is connected to the support bracket 20. The two ends of the first connecting square rod 53 are also partially retracted to form a cylindrical limit rod 531; the limit rod 531 is clearance-matched with the corresponding second guide groove 52. When the driving plate 51 moves laterally, the end of the first connecting square rod 53 can slide laterally along the first groove section 121 and vertically along the second groove section 122. Specifically, the width of the second guide groove 52 is smaller than that of the first guide groove 12, and the diameter of the limit rod 531 is smaller than that of the first connecting square rod 53. Under the restriction of the second guide groove 52, the limit rod 531 cannot move along its axial direction.

[0071] In this embodiment, both ends of the first connecting square rod 53 can move horizontally and vertically in the first guide groove 12. Since the limiting rod 531 is located in the second guide groove 52, when the driving plate 51 moves horizontally, the limiting rod 531 will not deflect in the second guide groove 52.

[0072] like Figure 4 and Figure 6 , the driving plate 51 moves to the left, pushing the first connecting square rod 53 to slide from right to left in the first slot section 121 to the lower end of the second slot section 122. As the driving plate 51 moves further to the left, the inclined second guide slot 52 pushes the limit rod 531 to rise, so that the first connecting square rod 53 rises, thereby completing the lateral movement and vertical rise of the support frame 20. That is, the nursing staff only needs to install the collection bag 30 on the support frame 20 on one side of the bed, and the support frame 20 can move from one side under the bed to the middle under the bed and then move up to the toilet port 60. No manual operation is required, which is efficient and saves time and effort.

[0073] In one embodiment, each of the mounting plates 11 is further provided with a third guide groove 13 symmetrical to the first guide groove 12 ; each of the driving plates 51 is further provided with a fourth guide groove 54 symmetrical to the second guide groove 52 .

[0074] The driving mechanism 50 also includes a second connecting square rod 55. The second connecting square rod 55 has the same shape and structure as the first connecting square rod 53. The cooperation mode among the second connecting square rod 55, the third guide groove 13 and the fourth guide groove 54 is the same as the cooperation mode among the first connecting square rod 53, the first guide groove 12 and the second guide groove 52. The second connecting square rod 55 is connected with a supporting column 70, and the supporting column 70 can be moved to the toilet opening 60 of the bed to support the patient. The supporting column 70 and the supporting bracket 20 can reach the toilet opening 60 successively.

[0075] In this embodiment, when the device is not in use, the support column 70 is located in the urinary and fecal opening 60, and the upper end of the support column 70 is flush with the upper end surface of the bed, which can support the patient's buttocks.

[0076] like Figure 4 and Figure 6 When the patient needs to defecate or urinate, the two driving plates 51 move to the left, and the fourth guide slot 54 also moves to the left, so that the third connecting square rod moves downward, and the supporting column 70 leaves the defecation and urination port 60 and moves downward and then to the left. Then, as the driving plate 51 moves further to the left, the supporting frame 20 on the first connecting square rod 53 together with the collecting bag 30 moves to the left and then moves upward to the bottom of the defecation and urination port 60 to receive the excrement.

[0077] That is, the lateral movement of the driving plate 51 can enable the supporting column 70 to leave or return to the defecation and urination opening 60 , and can also enable the supporting frame 20 together with the collecting bag 30 to move below the defecation and urination opening 60 .

[0078] In one embodiment, the upper end of the first connecting square rod 53 is connected to a base 71; two supports 72 are slidably provided on the upper end of the base 71; the sliding direction of the supports 72 is the same as the length direction of the first connecting square rod 53; and an electric push rod 73 is provided on the supports 72.

[0079] The support bracket 20 includes two first mounting blocks 21 , two second mounting blocks 22 and four supporting rods 23 .

[0080] Two first mounting blocks 21 symmetrically arranged with respect to each other are respectively connected to the output ends of the corresponding electric push rods 73 .

[0081] Two second mounting blocks 22 are symmetrically arranged, and one of the second mounting blocks 22 is connected to the base 71. Four supporting rods 23 are enclosed to form a parallelogram, and the two ends of each supporting rod 23 are rotatably connected to one first mounting block 21 and one second mounting block 22 respectively. The space enclosed by the four supporting rods 23 is used to install the collection bag 30. During the entire movement process of the first connecting square rod 53 and the second connecting square rod 55, the electric push rod 73 can adjust the extension and retraction of its output end as needed.

[0082] In this embodiment, the nursing staff installs the collection bag 30 in the space surrounded by the four supporting rods 23, and controls the two electric push rods 73 by setting a PLC control module (not shown). When the collection bag 30 needs to be installed, the output ends of the two electric push rods 73 extend, and the four supporting rods 23 form a square. When the collection bag 30 receives the excrement falling from the urinary and fecal opening 60, the four supporting rods 23 also form a square outline. After the collection bag 30 has received the excrement, the two electric push rods 73 retract at the same time, so that the four supporting rods 23 form a parallelogram, and the collection bag 30 therein gradually becomes deflated, thereby reducing the smell of the excrement inside it, and also preparing for the subsequent sealing mechanism 40 to seal the collection bag 30.

[0083] In one embodiment, a wall-hanging column 24 is connected to the inner side of each supporting rod 23, and one end of the wall-hanging column 24 away from the supporting rod 23 is connected to a limiting block 25; four wall-hanging holes are opened at the mouth of the collecting bag 30; the wall-hanging holes can be mounted on the corresponding wall-hanging column 24 and abut against the limiting block 25.

[0084] In this embodiment, the size of the limit block 25 is larger than that of the wall-mounted column 24, and the size of the wall-mounted hole at the mouth of the collecting bag 30 is adapted to the limit block 25. After the collecting bag 30 is hung on the wall-mounted column 24 through the wall-mounted hole, the limit block 25 abuts against the inner wall of the collecting bag 30 at the upper end of the wall-mounted hole, that is, the limit block 25 restricts the collection bag 30 from detaching.

[0085] In one embodiment, a bottom plate 80 is disposed between the two driving plates 51 , and the sealing mechanism 40 includes a first bracket 41 and a second bracket 43 .

[0086] The first bracket 41 is slidably disposed on the bottom plate 80 in a transverse direction. The first bracket 41 is located between the first connecting square rod 53 and the second connecting square rod 55. The first bracket 41 and the first connecting square rod 53 are slidably matched in a vertical direction. The first heating module 42 is connected to the surface of the first bracket 41 facing the second connecting square rod 55. Specifically, the first bracket 41 includes two vertical uprights, and the two uprights are connected to the first heating module 42 in a strip shape. A vertical dovetail groove is provided on the surface of the upright facing the first connecting square rod 53, and a dovetail block slidably matched with the dovetail groove is provided on the first connecting square rod 53 at a position corresponding to the dovetail groove.

[0087] The second bracket 43 is laterally slidably arranged on the bottom plate 80 , and is located between the first bracket 41 and the second connecting square rod 55 . The second bracket 43 and the second connecting square rod 55 are vertically slidably matched, and a second heating module 44 is connected to a surface of the second bracket 43 facing the first bracket 41 .

[0088] The first heating module 42 and the second heating module 44 are respectively located on both sides of the support frame 20. The first heating module 42 and the second heating module 44 are located below the support frame 20. The first heating module 42 and the second heating module 44 can perform heat-melt sealing on the collection bag 30 from both sides of the collection bag 30, which is a prior art and will not be described in detail here. The first heating module 42 and the second heating module 44 also control the heating timing through the PLC control module.

[0089] In this embodiment, Figure 4 and Figure 6 When the driving plate 51 moves to the left, the first connecting square rod 53 drives the first bracket 41 to move to the left, and the second connecting square rod 55 moves down at this time. Correspondingly, the second bracket 43 remains stationary. Therefore, the first heating module 42 on the first bracket 41 and the second heating module 44 on the second bracket 43 are close to and against each other. It should be noted that at this time, the first heating module 42 and the second heating module 44 are not powered.

[0090] Reference Figure 4 and Figure 6, assuming that the collection bag 30 has received all the excrement, the PLC control module controls the first heating module 42 and the second heating module 44 to be powered on for heating. At this time, the first connecting square rod 53 is located at the upper end of the second slot section 122 of the first guide groove 12. As the drive plate 51 moves rightward, the first connecting square rod 53 moves downward, the first bracket 41 temporarily remains stationary, and the second bracket 43 on the left side approaches the first bracket 41. The first heating module 42 and the second heating module 44 abut against each other and perform hot-melt sealing on the mouth of the collection bag 30 from both sides. Then the first connecting square rod 53 falls to the lower end of the second slot section 122 of the first guide groove 12 (the left end of the first slot section 121), and as the drive plate 51 further moves rightward, the first bracket 41 and the second bracket 43 are separated.

[0091] In one embodiment, two mounting holes 551 are provided on the second connecting square rod 55. A matching rod 56 is slidably provided in the mounting hole 551; one end of the matching rod 56 is vertically slidably matched with the second bracket 43, and the other end of the matching rod 56 is connected to a stopper 57; a spring 58 is sleeved on the matching rod 56; the two ends of the spring 58 are respectively against the stopper 57 and the second connecting square rod 55. The second bracket 43 is vertically slidably matched with the second connecting square rod 55 through the matching rod 56. The vertical sliding matching mode of the second bracket 43 and the matching rod 56 can refer to the matching mode (matching mode of dovetail block and dovetail groove) of the first bracket 41 and the first connecting square rod 53.

[0092] In this embodiment, when the first bracket 41 and the second bracket 43 are against each other, the matching rod 56 and the second bracket 43 can have a certain elasticity, so that the first heating module 42 and the second heating module 44 on the first bracket 41 and the second bracket 43 can ensure the tightness of the docking during operation.

[0093] In one embodiment, the driving mechanism 50 further includes a driving block 81 , a screw rod 82 and a motor 83 .

[0094] The driving block 81 is connected to the lower end of the bottom plate 80 and has a threaded hole. The screw 82 is threadedly connected to the threaded hole. The motor 83 is arranged on the frame 10, and its rotating shaft is coaxially connected to the screw 82. The bottom plate 80 and the driving plate 51 are driven to move horizontally by the rotation of the motor 83.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.
