Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a drainage device. Background Art

[0002] When clinical conditions such as cerebral hemorrhage and intracranial hydrops occur, a drainage device is usually used to extract the hydrops in the skull, thereby reducing the intracranial pressure of the patient. The intracranial pressure of the human body needs to be maintained within a certain range. Too high or too low intracranial pressure will make people feel unwell, such as headache, vomiting, etc. When the drainage device is in use, the drainage device drains cerebrospinal fluid and other hydrops out of the body to relieve symptoms such as cerebral edema and meningeal irritation, and regulate the intracranial pressure.

[0003] During the drainage process, if the flow rate of the hydrops is too fast or too slow, it will cause discomfort to the patient. Therefore, it is necessary to control the drainage rate. For existing drainage devices, medical staff can only judge whether the drainage speed is normal by observing the drainage volume every half hour or one hour. The operation process is too cumbersome and the accuracy is low. Utility Model Content

[0065] Embodiment

[0066] Refer to Figures 1 - 4 , in this embodiment, a drainage device is proposed, including:

[0067] A drainage catheter 100 for draining the effusion;

[0068] An effusion collection device 200 for collecting the effusion. Among them, the liquid discharge end of the drainage catheter 100 is connected to the effusion collection device 200, and a drip rate sensor 300 is provided on the effusion collection device 200;

[0069] A housing 400 for installing the effusion collection device 200. Among them, the effusion collection device 200 is slidably connected to the housing 400, and the slidable direction of the effusion collection device 200 relative to the housing 400 is parallel to the height direction of the housing 400;

[0070] A detection device 500 for detecting the relative position between the effusion collection device 200 and the housing 400;

[0071] A display device 600 is provided at the top of the housing 400. Among them, both the drip rate sensor 300 and the detection device 500 are electrically connected to the display device 600.

[0072] Refer to Figure 1 and Figure 20 , a connecting pipe 101 is detachably connected to the liquid inlet end of the drainage catheter 100. Among them, the connecting pipe 101 and the liquid inlet end of the drainage catheter 100 can be connected by means of plugging, screw connection, etc. The connecting pipe 101 is used to be connected to the patient's skull, so as to drain the effusion in the skull into the drainage catheter 100.

[0073] A power interface 610 is provided on the display device 600, and the power supply is connected to the power interface 610 through a power cord, thereby realizing the power supply to the electrical components of the drainage device. It should be noted that the power cord is not shown in the drawings, and Figure 3 the effusion collection device 200 is not shown in

[0074] The back side of the housing 400 is equipped with a back plate 700. Before using the drainage device, the housing 400 can be installed on components such as a bracket through the chuck 710 on the back plate 700. A horizontal detection device 500, such as a gyroscope, can be provided on the housing 400. Among them, the horizontal detection device 500 is electrically connected to the display device 600, and whether the housing 400 is in a vertical state can be detected through the horizontal detection device 500.

[0075] During drainage, the drip rate of the effusion is detected by the drip rate sensor 300, and the height position of the effusion collection device 200 on the housing 400 is detected by the detection device 500. When the drip rate does not meet the requirements, the height position of the effusion collection device 200 on the housing 400 is adjusted. Due to the pressure difference, the drip rate will be adjusted.

[0076] An installation part 720 is provided on the back plate 700, and a laser pointer 721 is inserted into the installation part 720. Among them, the laser pointer 721 is separable from the installation part 720. When the detection device 500 fails, medical staff can align the laser emitted by the laser pointer 721 with the scale on the housing 400, thereby reading the height of the effusion collection device 200 on the housing 400 to ensure the accuracy of the reading. A storage box 730 is also provided on the back plate 700, and the storage box 730 can be used to place items.

[0077] As Figure 2 shown, the drip rate sensor 300 is electrically connected to a first line 310, and the first line 310 is detachably electrically connected to the display device 600. The first line 310 is located outside the housing 400. Since the first line 310 and the display device 600 can be detached, when the drainage device is idle, the first line 310 can be detached, thereby facilitating storage and protecting the first line 310.

[0078] The detection device 500 includes a reading module and a scale module 520. The reading module is fixedly connected to the effusion collection device 200, and the scale module 520 is fixed inside the housing 400. The scale module 520 is arranged parallel to the height direction of the housing 400. Among them, the reading module is arranged on the circuit board module 510, and the reading module is not shown in the drawings.

[0079] As Figure 3 and Figure 4 shown, the reading module is electrically connected to a second line 530, and the second line 530 is electrically connected to the display device 600. A cylinder 420 is provided inside the housing 400, and the second line 530 is wound around the cylinder 420.

[0080] Since the liquid accumulation collection device 200 is slidable relative to the housing 400, the distance between the liquid accumulation collection device 200 and the top of the housing 400 is not fixed. To meet the requirement of the maximum distance, the second circuit 530 must have a certain length. The second circuit 530 is wound around the column 420, and the column 420 can play a certain role in restraining the second circuit 530, avoiding situations such as knotting and excessive bending of the second circuit 530 inside the housing 400, thereby playing a role in protecting the second circuit 530 and making the routing of the second circuit 530 inside the housing 400 more neat and regular.

[0081] The reading module includes a signal generation module.

[0082] In some embodiments, the signal generation module is configured to generate a magnetic signal, and the scale module 520 includes a magnetic scale tape. When the liquid accumulation collection device 200 moves relative to the housing 400, the position of the liquid accumulation collection device 200 in the height direction of the housing 400 will change. At the same time, the signal generation module moves synchronously with the liquid accumulation collection device 200. Correspondingly, the relative position between the signal generation module and the scale module 520 will also change. By reading the information of the magnetic scale tape through the reading module, the position information of the liquid accumulation collection device 200 on the housing 400 can be obtained. Specifically, in this embodiment, the specific structure and working principle of the detection device 500 can refer to a magnetic grating sensor.

[0083] In other embodiments, the signal generation module is configured to generate an optical signal, and the scale module 520 includes a grating scale tape. Specifically, in this embodiment, the specific structure and working principle of the detection device 500 can refer to a grating sensor.

[0084] In this embodiment, the detection device 500 includes a circuit board module 510, and the reading module is arranged on the circuit board module 510.

[0085] Such as Figure 5 and Figure 6 As shown, the circuit board module 510 is installed and fixed on the seat body 540, and the seat body 540 is connected to the liquid accumulation collection device 200. Among them, when the liquid accumulation collection device 200 slides relative to the housing 400, the seat body 540 moves synchronously with the liquid accumulation collection device 200.

[0086] A slide rail 410 is arranged inside the housing 400, and the scale module 520 is fixed on the slide rail 410. The slide rail 410 is arranged parallel to the height direction of the housing 400.

[0087] The base body 540 is provided with a buckle 541 and a wire clamp 542. The buckle 541 is buckled on the slide rail 410, and the wire clamp 542 is for the second circuit 530. When the liquid accumulation collecting device 200 moves relative to the housing 400, the base body 540 moves synchronously with the liquid accumulation collecting device 200. At this time, through the mutual cooperation of the buckle 541 and the slide rail 410, the stability of the movement of the base body 540 is ensured. The wire clamp 542 of the base body 540 fixes a part of the second circuit 530. When the base body 540 moves, the part of the second circuit 530 fixed by the wire clamp 542 will move synchronously with the base body 540, avoiding situations such as knotting and excessive bending of the second circuit 530 inside the housing 400, thereby playing a role in protecting the second circuit 530 and making the routing of the second circuit 530 inside the housing 400 neater and more standardized.

[0088] As Figure 4 shown, the column body 420 is arranged on the slide rail 410 and on the side facing away from the scale module 520.

[0089] The slide rail 410 can be fixedly connected to the housing 400 by screws; a threaded hole is provided inside the column body 420. During assembly, first, the slide rail 410 is installed inside the housing 400, and then, the back plate 700 is assembled on the housing 400. Among them, a screw passes through the holes on the storage box 730 and the back plate 700 and is threadedly connected to the threaded hole on the column body 420, realizing the fixed connection among the storage box 730, the back plate 700, and the slide rail 410.

[0090] As Figure 1 shown, a sliding connection device 800 is provided on the liquid accumulation collecting device 200.

[0091] As Figure 7 and Figure 8 shown, the housing 400 includes a panel 430, and a sliding through groove 431 is opened on the panel 430. Among them, the sliding connection device 800 is slidably connected to the sliding through groove 431, and the sliding through groove 431 is arranged parallel to the height direction of the housing 400. Through the cooperation between the sliding connection device 800 and the sliding through groove 431, the liquid accumulation collecting device 200 can move in the height direction of the housing 400.

[0092] Furthermore, the housing 400 further includes a partition plate 440. An accommodation groove 450 is formed between the partition plate 440 and the panel 430, and a communication groove 441 is opened on the partition plate 440. Both the accommodation groove 450 and the communication groove 441 are arranged parallel to the height direction of the housing 400, and the communication groove 441, the accommodation groove, and the sliding through groove 431 are communicated in sequence.

[0093] As Figures 9 - 17As shown, the sliding connection device 800 includes a plugging portion 810, a first component 820, and a second component 830. The plugging portion 810 is inserted through the sliding through groove 431 and is slidably connected to the sliding through groove 431. Among them, the slidable direction of the plugging portion 810 relative to the sliding through groove 431 is parallel to the height direction of the housing 400. In this embodiment, both the first component 820 and the second component 830 are plate-like structures with uniform thickness.

[0094] The first component 820 is slidably disposed in the placement groove 450, the second component 830 is located on the side of the panel 430 away from the placement groove 450, and the base body 540 is located on the side of the partition 440 away from the placement groove 450.

[0095] By providing the partition 440 and the panel 430, the space can be divided into three regions for accommodating the base body 540, the first component 820, and the second component 830 respectively; the communication groove 441, the placement groove, and the sliding through groove 431 are arranged in sequence and communicate with each other to ensure that the base body 540, the first component 820, and the second component 830 can move synchronously along the height direction parallel to the housing 400.

[0096] In this embodiment, the first component 820 is fixedly connected to the plugging portion 810, and the second component 830 is configured to be movable relative to the first component 820.

[0097] A connection through hole 831 is provided on the second component 830, and an adjusting member 840 is rotatably disposed in the connection through hole 831. The adjusting member 840 is configured to drive the first component 820 to move relative to the second component 830 to adjust the distance between the first component 820 and the second component 830, so that the first component 820 and the second component 830 clamp or loosen the panel 430.

[0098] The adjusting member 840 can be an adjusting bolt, and a connection screw hole 821 is provided on the first component 820. Among them, the adjusting screw is threadedly connected to the connection screw hole 821. By screwing the adjusting bolt, the distance between the first component 820 and the second component 830 can be adjusted, thereby enabling the first component 820 and the second component 830 to clamp or loosen the panel 430. In this embodiment, screwing the adjusting bolt clockwise causes the first component 820 and the second component 830 to clamp the panel 430, and screwing the adjusting bolt counterclockwise causes the first component 820 and the second component 830 to loosen the panel 430. In other embodiments, adjusting bolts and connection screw holes 821 with other rotation directions can be provided to achieve: screwing the adjusting bolt clockwise causes the first component 820 and the second component 830 to loosen the panel 430, and screwing the adjusting bolt counterclockwise causes the first component 820 and the second component 830 to clamp the panel 430.

[0099] When the first component 820 and the second component 830 clamp the panel 430, the sliding connection device 800 is in a relatively fixed state with respect to the panel 430. Correspondingly, the liquid accumulation collection device 200 cannot slide relative to the housing 400. At this time, on the housing 400, the liquid accumulation collection device 200 is located at a fixed height position.

[0100] When it is necessary to adjust the height position of the liquid accumulation collection device 200 on the housing 400, the adjusting bolt is screwed counterclockwise to adjust the distance between the first component 820 and the second component 830, so that the first component 820 and the second component 830 loosen the panel 430. In this way, the sliding connection device 800 can be moved. Correspondingly, the liquid accumulation collection device 200 moves synchronously with the sliding connection device 800. After the liquid accumulation collection device 200 moves to the expected position, the adjusting bolt is screwed clockwise so that the first component 820 and the second component 830 clamp the panel 430.

[0101] In this embodiment, the seat body 540 is provided with a socket hole, and a part of the adjusting member 840 is inserted into the socket hole. With the cooperation between the adjusting member 840 and the socket hole, when the sliding connection device 800 moves, the seat body 540 will move synchronously therewith, thereby driving the reading module to move.

[0102] As Figures 13 - 15 shown, the second component 830 includes an inner side surface 832, and the inner side surface 832 faces the side where the first component 820 is located. An abutting member 833 is provided on the inner side surface 832. The abutting member 833 is configured to abut against the first component 820 by passing through the sliding through groove 431.

[0103] The abutting member 833 includes an abutting surface 834. From the top to the bottom of the abutting member 833, the distance between the abutting surface 834 and the inner side surface 832 gradually increases. The height direction of the second component 830 is consistent with the height direction of the housing 400. Among them, the adjusting member 840 is closer to the top of the second component 830 than the bottom of the second component 830.

[0104] Taking the drainage device in the use state as an example. When the first component 820 and the second component 830 are at the maximum distance, the first component 820 and the second component 830 are in a parallel state and both are in a vertical state. At this time, the abutting surface 834 abuts against the first component 820, thereby realizing the restraint of the second component 830 and preventing the second component 830 from being in an overly loose state.
