Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the drainage device provided by the present invention is shown. The drainage device includes support 10 and is used for installing the mounting bracket 20 of drainage bottle 60, the drainage device still includes: the lifting mechanism is connected with the mounting frame 20 and is used for controlling the mounting frame 20 to lift relative to the support 10; a flow rate measurer mounted on the mounting frame 20, for measuring the drainage rate of the drainage bottle 60; and the controller is connected with the flow rate measurer and the lifting mechanism, and is used for controlling the lifting mechanism to lift the mounting rack 20 according to the drainage speed so as to adjust the height of the drainage bottle 60.

Specifically, drainage device is when using, installs drainage bottle 60 on mounting bracket 20, drainage catheter's one end penetrates the ventricle and draws forth cerebrospinal fluid, and the other end is connected in order to introduce cerebrospinal fluid to drainage bottle 60 with drainage bottle 60, and drainage bottle 60 still is connected with the hydrops bag, and the hydrops bag is used for collecting drainage liquid, support 10 is fixed mutually in order to form the support with the transfusion rod of sick bed. The drainage bottle 60 may be an anti-reflux bottle to prevent drainage fluid from flowing backwards. The flow rate measurer is installed on the mounting frame 20 to move together with the drainage bottle 60, and can measure the drainage rate of the drainage bottle 60 in real time no matter how the height of the drainage bottle 60 is adjusted. The controller is an IC module with a wireless networking function, and when the drainage speed is too high, the controller controls the lifting mechanism to lift the mounting frame 20 to lift the drainage bottle 60, so that the drainage liquid guiding speed is reduced; the controller is in when drainage speed is too slow, control elevating system reduces mounting bracket 20, reduces drainage bottle 60 to accelerate the derivation speed of drainage liquid.

Through implementing this embodiment, utilize real-time measurement's drainage speed to adjust drainage bottle 60's height, can improve the accuracy of regulation, avoid excessive drainage or drainage not enough, guarantee intracranial pressure's stability, do not need medical personnel to take notes the drainage condition constantly, realize automatically regulated, greatly saved manpower resources.

In one embodiment, as shown in fig. 2, the flow rate measurer is a dropping speed measurer 30, the dropping speed measurer 30 is installed on the mounting frame at a position corresponding to the mouth of the drainage bottle, and the dropping speed measurer 30 is used for measuring the dropping speed of the drainage liquid in the drainage bottle.

Specifically, the dripping speed measuring device 30 may be an infrared sensor or a laser sensor, and the mounting position of the dripping speed measuring device 30 is flush with the dripping position of the drainage bottle 60, so that the emitted infrared beam or laser beam can accurately sense the dripping of drainage liquid, thereby measuring the drainage speed. In addition, since the product specification of the drainage bottle 60 is determined, and the volume value of each drop of liquid is the same, for example, the volume of each drop of drainage liquid is 1ml, the drainage rate can be expressed by the number of drops flowing through in unit time, for example, 10 drops per minute is measured, and the drainage rate is 10 ml/min. Therefore, the drainage speed can be directly measured by the dropping speed measurer.

In one embodiment, as shown in fig. 2, the drainage device further comprises a weight measurer 40 connected to the controller, wherein the weight measurer 40 is installed on the mounting frame 20 at a position where the drainage bottle 60 is connected, and the weight measurer 40 is used for measuring the weight of the drainage fluid. It should be noted that, since the drainage liquid in the drainage bottle 60 will normally flow directly to the effusion cell without being damaged in the drainage bottle 60, the weight of the drainage liquid measured in this embodiment is the sum of the weights of the drainage liquid in the drainage bottle 60 and the effusion cell. It will be appreciated that in practice, the drainage bottle 60 is connected to the drip bag and the weight of the drainage fluid can be measured using the weight measurer 40.

Specifically, the weight measurer 40 may be a weighing sensor or a gravity sensor, and is installed at the junction of the mounting frame 20 and the drainage bottle 60 to move together with the drainage bottle 60, and the weight measurer 40 can measure the weight of the drainage fluid in real time regardless of the height adjustment of the drainage bottle 60.

Although it can be understood that the drainage rate can be directly measured by the dripping speed measuring device 30, in the practical application process, the drainage bottle 60 has a plurality of product specifications, the drainage bottles 60 with different product specifications have different volume values of each drop of liquid, and the different sizes of the drops of liquid can lead to different drainage rates. Therefore, the drainage speed measurement device 30 is used for measuring the drainage speed, the volume value of the dropping liquid corresponding to the drainage bottle 60 needs to be obtained in advance, and the drainage speed measurement device cannot be suitable for the measurement of the drainage speeds of the drainage bottles 60 with different specifications.

In the embodiment, the drainage speed is determined by the weight of the drainage fluid, and specifically, the drainage speed can be obtained by dividing the weight of the drainage fluid introduced in a unit time by the unit time, for example, if the weight of the drainage fluid introduced in 1 minute is 10g, the drainage speed is 10 g/min. Therefore, the drainage speed can be determined without the volume of dropping liquid, the drainage bottle 60 can adapt to drainage bottles 60 of different specifications, and the universality is realized. The controller can adjust the height of drainage bottle 60 according to drainage liquid weight, converts the weight of drainage liquid into drainage speed and then comes the height of automatically regulated drainage bottle 60 through elevating system, and its control logic is the same with above-mentioned embodiment, no longer explains here.

It should be noted that the weight measuring device 40 in this embodiment may be used for measuring the drainage rate, or may be used for measuring the weight of the drainage fluid only. The drainage rate may be measured by the drip speed measuring device 30 alone or by the weight measuring device 40 alone.

In one embodiment, the drainage device further comprises a drainage switch (not shown) connected to the controller, the drainage switch being mounted on the mounting frame 20, and the drainage switch being used to connect to a drainage catheter for introducing drainage fluid into the drainage bottle 60, so as to open or close the introduction of the drainage fluid.

In a specific implementation, the drainage switch can be a mechanism with a clamping function, for example, the drainage switch can be a clamp and a driving member for driving the clamp to clamp the drainage catheter, the driving member is connected with a controller, and the controller can control the driving member to drive the clamp to clamp the drainage catheter. When the clamp clamps the drainage catheter, the clamp applies pressure to the drainage catheter to clamp the drainage catheter, and drainage liquid cannot be led into the drainage bottle 60 from the drainage catheter, so that the leading-in of the drainage liquid is closed; when the clip loosens the drainage catheter, the drainage fluid can be smoothly guided into the drainage bottle 60 from the drainage catheter, so that the guide of the drainage fluid is started. This embodiment adopts outside mechanical structure to realize the leading-in switch of drainage liquid, need not to adopt valve control's drainage catheter, and what kind of drainage catheter homoenergetic realizes the control that the drainage liquid switched on, has the commonality.

Specifically, as shown in FIG. 3, the hanging member 22 may be a hook disposed on the top of the sliding plate 21, and the drainage bottle 60 is hung from the hook. The sliding plate 21 can slide relative to the second mounting plate 12, the drainage bottle 60 is mounted on the sliding plate 21 through the hook and slides along the sliding plate 21, and the lifting mechanism drives the sliding plate 21 to move so as to adjust the height of the drainage bottle 60.

Furthermore, the sliding plate 21 is further provided with a limiting ring 23 for the drainage bottle 60 to penetrate through, wherein the caliber of the limiting ring 23 is adjustable. The spacing ring 23 can be an elastic bandage, for example, the drainage bottle 60 is arranged in the hole of the elastic bandage in a penetrating way, and the bottle body of the drainage bottle 60 is hooped by the elastic bandage to avoid shaking and ensure the drainage effect. The elasticity of the elastic bandage can be adjusted, namely the caliber of the elastic bandage can be adjusted, so that the elastic bandage is suitable for drainage bottles 60 of different shapes and specifications and has universality.

Specifically, the starting position of the hanging height of the drainage bottle 60 is the zero point position, which is usually the horizontal line of the external auditory canal when the patient is lying on his back, and the nasal midline when the patient is lying on his side. Because the size and the contour of the head of each patient are different, the zero point position corresponding to the patient is also different, and therefore, the uncertainty of the zero point position can lead to the progress of drainage adjustment. In order to solve this problem, the present embodiment has a graduated scale 111 mounted on the first mounting plate 11, and a zero point detector 50 is disposed at a zero point scale of the graduated scale 111, the zero point detector 50 being used for detecting zero point positions corresponding to different patients. The zero point detector 50 may be a laser locator. After the zero point position is determined, the zero point scale of the graduated scale 111 is driven by the first driving assembly to move to be aligned with the zero point position, so that the zero point position can be accurately determined, the accuracy of the height of the drainage bottle 60 is ensured, and the drainage precision is improved.

Specifically, the external portion in this embodiment generally refers to an infusion rod of a hospital bed, or a head rod, and may be a member having a certain height. The supporting member 112 may be a clip, a buckle, or other fastening member, a pressing member, etc., as long as it can be fixed outside, i.e. fixed with the infusion rod or the bedside rod to form a support for the whole drainage device. Through setting up support piece 112 in the contained angle space, wipe the drainage condition from medical personnel's visual angle, support piece 112 is hidden in the contained angle space, can't see support piece 112, and whole drainage device is unsettled on the sick bed, and is clean and tidy pleasing to the eye.

In an embodiment, the drainage device further includes an alarm (not shown in the figure), the alarm is connected to the controller, and the alarm is used for alarming when the mounting frame 20 is lifted to exceed the current limit interval.

Specifically, as the patient's condition changes, the drainage rate also changes, and when the patient has a sudden condition, the drainage rate is too fast or too slow, which may cause the height of the drainage bottle 60 to exceed the set range. The set range specifically refers to a limit interval, the limit interval is obtained in the controller in advance, or is determined by the terminal and then sent to the controller, the limit interval during the drainage is the current limit interval, and the limit interval is composed of an upper limit value and a lower limit value of the height in the lifting process of the drainage bottle 60, for example, 100 plus 180mm, that is, the height of the drainage bottle 60 should not exceed the interval. And the height of the drainage bottle 60 is beyond the set range, namely the height of the drainage bottle 60 is abnormal. It should be noted that, because the drainage bottle is followed the mounting bracket motion, the distance of mounting bracket distance zero point is the height of drainage bottle promptly, consequently, when mounting bracket 20 goes up and down to surpassing current spacing interval, at this moment, the alarm is reported to the police to controller control alarm, the alarm is audible-visual annunciator, through the interference of vision and sense of hearing to remind patient family members or medical personnel patient to appear the situation, make patient can in time obtain the treatment.

In an embodiment, the device further comprises an upper baffle (not shown) and a lower baffle (not shown) which are mounted on the second mounting plate 12 and used for limiting the lifting of the mounting frame 20, and the upper baffle and the lower baffle can move and adjust along the axis of the second mounting plate 12.

Specifically, because each patient does not have data of a historical limit interval which can be referred to when using the drainage device for the first time, feedback control cannot be formed, and therefore, the lifting range of the drainage bottle 60 cannot be effectively controlled when each patient uses the drainage device for the first time. In order to solve patient's when using for the first time, because feedback parameter's disappearance leads to the drainage to adjust inaccurately, this embodiment is right through setting up adjustable overhead gage and lower baffle the height that mounting bracket 20 goes up and down carries out machinery spacingly, need not to refer to historical data, and the position of baffle is right about the manual regulation according to patient's actual conditions by medical personnel mounting bracket 20 forms the spacing interval of a physics, and excessive drainage or drainage are not enough when can avoiding using for the first time effectively. In addition, when the automatic adjustment fails, for example, when the control logic has an error, the physical limit structure can limit the lifting height of the drainage bottle 60, so that the drainage adjustment precision is further improved. The upper baffle plate and the lower baffle plate can be installed on the second baffle plate back to one surface of the included angle space, namely one side facing medical staff, so that the medical staff can adjust the included angle space, the upper baffle plate and the lower baffle plate are provided with sliding ends, the sliding ends can slide in the first guide holes 121, and then the upper baffle plate and the lower baffle plate can move along the axis of the second mounting plate 12. It is understood that the upper baffle and the lower baffle may have other types of specific structures, and are not limited thereto.

Referring to fig. 6, fig. 6 is a flowchart of a control method of a drainage device according to an embodiment of the present invention, where the drainage device is the drainage device described in the above embodiment, and the drainage device interacts with a terminal to implement the control method. The controller is used for executing the control method, and the control method comprises the steps S101-S103.

And S101, acquiring the current drainage speed.

In one embodiment, the current drainage rate may be a rate that is metered by volume. When the flow rate measurer is used, the product specification of the drainage bottle is determined, the cross section of the pipeline of the drainage bottle is also determined, and therefore the volume of each drop is also determined. For example, one drop has a volume of 1ml, the flow rate meter measures 10 drops in one minute, and the current drainage rate is 10 ml/min.

In other embodiments, the drainage rate may also be a rate measured by weight. When the weight measurer is used, no matter what product specification the drainage bottle is, the drainage speed can be measured, and the current drainage speed can be obtained by dividing the weight of the introduced drainage liquid by the introduction time, for example, the weight measurer measures that the weight of the drainage liquid dropped into the drainage bottle is 10g in one minute, and then the current drainage speed is 10 g/min. It should be noted that the time interval for obtaining the drainage rate may be 1 minute, 5 minutes, 10 minutes, and any other time, and is not limited herein.

S102, when the current drainage speed is higher than a preset drainage speed, controlling the lifting mechanism to lift the mounting frame.

S103, when the current drainage speed is lower than a preset drainage speed, controlling the lifting mechanism to adjust and descend the mounting frame.

In one embodiment, the preset drainage speed is the drainage speed preset by a doctor using a terminal, the preset drainage speed is set at the terminal and then sent to the controller, and the height of the drainage bottle is automatically adjusted by comparing the preset drainage speed with the current drainage speed obtained by the flow rate measurer. The preset drainage speed is determined by the preset total drainage quantity and drainage time. For example, if the patient has 150ml of cerebrospinal fluid to be drained and the 150ml of cerebrospinal fluid needs to be drained within 24 hours, the drainage rate per unit time, for example 1 minute, can be determined based on the total amount and time of the drainage. The acquired current drainage rate is also acquired at intervals of unit time, so that the acquired current drainage rate can be compared with the preset drainage rate.
