Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drainage structure and a drainage method after spinal surgery. Background Art

[0002] After spinal surgery, some exudates such as blood, pus, and tissue fluid accumulate in the surgical site. Spinal drainage tubes are usually used to drain the exudates produced after surgery during spinal surgery to reduce tissue swelling and prevent infection. During the operation, the doctor will place the drainage tube near the surgical site so that the fluid produced after the operation can be drained out of the body through the drainage tube to prevent them from accumulating in the tissues, thereby alleviating symptoms such as pain and swelling.

[0003] Specifically, on the basis of conventional drug treatment, the treatment group adopts the timed closure and intermittent drainage method, that is, every 2 hours of closure, open drainage for 5-10 minutes. During the open drainage, a professional nurse will observe at the bedside. If the patient shows violent agitation, violent coughing, breath holding and exertion, the drainage tube will be clamped immediately to prevent excessive drainage of cerebrospinal fluid caused by a short-term sudden increase in pressure, and reflux of cerebrospinal fluid or gas into the brain caused by the subsequent sudden drop in pressure. When the symptoms are stable, the drainage tube will be opened to complete the planned drainage.

[0004] However, in current clinical practice, intermittent clamping drainage is to clamp the drainage tube with a clamp, and the clamping time is set by medical staff, or a timer is placed at the bedside, which can alarm at a fixed time after the time is up. In addition, the flow rate is controlled by manual pinching and releasing by medical staff. All of the above are the results of medical staff's observation based on their own experience, which requires a lot of energy to monitor the clamping. If the medical staff is inexperienced, it is easy to cause inaccurate control, thus endangering the patient's life. Therefore, the above problems need to be improved. Summary of the invention

[0005] The present invention provides a drainage structure and drainage method after spinal surgery, which can realize precise control of intermittent clamping of the drainage tube, and can also realize precise control of the flow rate of the accumulated fluid in the drainage tube, so that the flow rate of the accumulated fluid in the drainage tube is maintained at the target flow rate. The specific implementation methods are as follows: A postoperative drainage structure for spine surgery, comprising a drainage tube body having a drainage channel, wherein the drainage tube body is connected to an external negative pressure drainer; A flow rate sensor is arranged on the drainage tube body, and is used to detect the flow rate of the accumulated fluid in the drainage channel; A temperature sensor is disposed on the drainage tube body, and is used to detect the temperature of the accumulated fluid in the drainage tube body; A control unit, which is arranged on the drainage tube body, and is used to control the flow rate of the accumulated fluid in the drainage channel or the opening and closing of the drainage channel; A flow sensor is disposed on the drainage tube body, and is used to detect the flow of the accumulated fluid in the drainage channel; The alarm unit is relatively movably arranged on the drainage tube body, and the flow rate of the accumulated fluid in the drainage channel can trigger the alarm unit to respond.

[0006] As a further solution of the present invention, the alarm unit includes a power supply, a sensing probe, a trigger unit, and a response unit. The sensing probe is connected to the positive pole of the power supply, and the negative pole of the power supply is connected to the trigger unit and the response unit in sequence.

[0007] As a further solution of the present invention, at least three groups of sensing probes are provided, and the three groups of sensing probes are connected to the positive pole of the power supply. Under the action of the accumulated fluid in the drainage channel, each group of sensing probes can contact the trigger unit to trigger the response unit to alarm.

[0008] As a further solution of the present invention, three groups of trigger units are provided corresponding to the sensing probes, and the three groups of trigger units are relatively movably arranged in the drainage channel of the drainage tube body.

[0009] As a further solution of the present invention, a first elastic member is provided between each group of the trigger units, and when the trigger unit loses the effect of the accumulated fluid in the drainage channel, the first elastic member drives the trigger unit to reset.

[0010] As a further solution of the present invention, the trigger unit includes a pressure sensing slide, a trigger member movably arranged on the pressure sensing slide, and a touch switch. The trigger member is arranged relative to the sensing probe. When the sensing probe collides with the trigger member, the trigger member is driven to move, so that the trigger member contacts the touch switch to trigger the response unit to alarm.

[0011] As a further solution of the present invention, the trigger member includes a connecting rod, and a contact head and a moving block respectively arranged on the connecting rod. The moving block can interfere with the sensing probe. When the sensing probe interferes with the trigger member, the trigger member is driven to move, so that the contact head contacts the touch switch.

[0012] As a further solution of the present invention, the moving block has a second inclined surface, and the sensing probe is provided with a first inclined surface corresponding to the second inclined surface, and when the first inclined surface abuts against the second inclined surface, the movement of the triggering member is realized.

[0013] As a further solution of the present invention, a second elastic member is provided on the connecting rod, and both ends of the second elastic member are supported on the moving block and the pressure sensing slide. When the moving block loses the force of the sensing probe, the second elastic member drives the moving block to reset.

[0014] In addition, the present invention also provides a method for drainage after spinal surgery, comprising a flow velocity detection module, a flow velocity control module, a flow rate detection module, a timing module, an alarm module, a data analysis module, and a cloud server, wherein the flow velocity detection module and the flow rate detection module are used to detect the flow velocity and flow rate of the object to be detected in the test area, and the information of the object to be detected in the test area is obtained, and the data analysis module is used to obtain the information and transmit the analysis data to the cloud server, and the cloud server controls the flow velocity control module according to the obtained information to maintain the flow velocity of the object to be detected in the test area at the target flow velocity; The timing module and the alarm module formulate parameters, and the cloud server controls the timing module and the alarm module to work according to the formulated parameters.

[0024] In this embodiment, combined with Figure 5 As shown, at least three groups of sensing probes 62 are provided, and the three groups of sensing probes 62 are connected to the positive electrode of the power supply. Under the action of the accumulated fluid in the drainage channel, each group of sensing probes 62 can contact the trigger unit to trigger the response unit 68 to alarm. The sensing probe 62 includes a first probe 621, a second probe 622, and a third probe 623. The first probe 621, the second probe 622, and the third probe 623 are all connected to the positive electrode of the power supply. The first probe 621, the second probe 622, and the third probe 623 have the same orientation. When the first probe 621, the second probe 622, or the third probe 623 contacts the trigger unit, the response unit 68 is triggered to alarm.

[0025] Specifically, three groups of trigger units are provided corresponding to the sensing probes 62, and the three groups of trigger units are relatively movable and arranged in the drainage channel of the drainage tube body 1. The trigger unit includes a pressure sensing slide, a trigger member movably arranged on the pressure sensing slide, and a touch switch, and the trigger member is arranged relative to the sensing probe 62. When the sensing probe 62 contacts the trigger member, the trigger member is driven to move, so that the trigger member contacts the touch switch, so as to trigger the response unit 68 to alarm.

[0026] In this embodiment, the pressure-sensing slide includes a first pressure-sensing slide 61, a second pressure-sensing slide 63, and a third pressure-sensing slide 64. A trigger mechanism 66 is provided on the front of the first pressure-sensing slide 61, the second pressure-sensing slide 63, and the third pressure-sensing slide 64. The trigger mechanism 66 includes a first trigger component 661, a second trigger component 662, and a third trigger component 663. The first probe 621, the second probe 622, and the third probe 623 are respectively provided on the back of the first pressure-sensing slide 61, the second pressure-sensing slide 63, and the third pressure-sensing slide 64 corresponding to the first trigger component 661, the second trigger component 662, and the third trigger component 663.

[0027] In this embodiment, combined with Figure 6 As shown, the first pressure sensing slide 61 is axially arranged in the drainage tube body 1, and a slider 611 is arranged on the first pressure sensing slide 61. The drainage tube body 1 has a guide groove 13 corresponding to the slider 611. The slider 611 is arranged in the guide groove 13 and can be slidably connected along the guide groove 13.

[0028] Specifically, a first elastic member is provided between each group of the trigger units, and when the trigger unit loses the effect of the accumulated liquid in the drainage channel, the first elastic member drives the trigger unit to reset. Preferably, the first elastic member is set as a first reset spring 67, and the first reset spring 67 is provided between the first pressure sensing slide 61 and the second pressure sensing slide 63, and between the second pressure sensing slide 63 and the third pressure sensing slide 64. When the first pressure sensing slide 61 and the second pressure sensing slide 63 lose the effect of the accumulated liquid in the drainage channel, the first reset spring 67 drives the first pressure sensing slide 61 and the second pressure sensing slide 63 to reset.

[0029] Specifically, the first trigger assembly 661 includes a frame 6611 disposed on the first pressure sensing carriage 61, and a trigger member is movably disposed on the frame 6611. The trigger member includes a connecting rod 6614, and a contact head 6613 and a moving block 6616 respectively disposed on the connecting rod 6614. The moving block 6616 can contact the sensing probe 62. When the sensing probe 62 contacts the trigger member, the trigger member is driven to move, so that the contact head 6613 contacts the touch switch. The first probe 621 contacts the moving block 6616 and pushes the moving block 6616, the connecting rod 6614 and the contact head 6613 to move in the direction of the touch switch. When the contact head 6613 contacts the touch switch, the response unit 68 alarms to remind the medical staff that the flow rate of the effusion is fast.

[0030] Specifically, the touch switch includes a first touch switch 6612, a second touch switch 6622, and a third touch switch 6632. The moving block 6616 has a second inclined surface 6616a.

When the first inclined surface 6211 abuts against the second inclined surface 6616a, the movement of the triggering member is realized. The first inclined surface 6211 and the second inclined surface 6616a have the same inclination angle. When the first inclined surface 6211 and the second inclined surface 6616a are completely in contact, the contact head 6613 contacts the touch switch, triggering the response unit 68 to realize the alarm operation.

[0031] Specifically, a second elastic member is provided on the connecting rod 6614, and both ends of the second elastic member abut against the moving block 6616 and the pressure sensing carriage. When the moving block 6616 loses the force of the sensing probe 62, the second elastic member drives the moving block 6616 to reset. Preferably, the second elastic member is configured as a second reset spring 6615, and the second reset spring 6615 can drive the connecting rod 6614 to achieve a reset function.

[0032] Embodiment 2, combined Figure 7 As shown, the present invention also provides a drainage method after spinal surgery, including a flow rate detection module 100, a flow rate control module 200, a flow rate detection module 300, a timing module 400, an alarm module 500, a data analysis module 800, and a cloud server 900. The flow rate detection module 100 and the flow rate detection module 300 detect the flow rate and flow rate of the object to be detected in the test area to obtain the information of the object to be detected in the test area, and the data analysis module 800 obtains the information and transmits the analysis data to the cloud server 900. The cloud server 900 controls the flow rate control module 200 according to the obtained information to maintain the flow rate of the object to be detected in the test area at the target flow rate; The timing module 400 and the alarm module 500 are configured with parameters, and the cloud server controls the timing module 400 and the alarm module 500 to work according to the configured parameters.

[0033] Specifically, the cloud server 900 is configured as a computer, which can issue instructions to the controller and display data information. Three groups of trigger units are configured, each group of trigger units includes a first touch switch 6612, a second touch switch 6622, and a third touch switch 6632. The first touch switch 6612, the second touch switch 6622, and the third touch switch 6632 are respectively configured corresponding to the first probe 621, the second probe 622, and the third probe 623. In specific applications, under the action of the effusion flow rate, the first probe 621 connected to the first pressure sensing slide 61 is driven to move, and the first inclined surface 6211 of the first probe 621 is completely fitted with the inclined surface of the second inclined surface 6616a, so that the connecting rod 6614 drives the contact head 6613 to contact the first touch switch 6612, thereby triggering the response unit 68 to realize the alarm operation.

[0034] In specific applications, medical staff can close the first touch switch 6612 and the third touch switch 6632 according to the required flow rate information. At this time, the second probe 622 and the second trigger component 662 work to trigger the response unit 68 to alarm; when the flow rate increases, the first touch switch 6612 and the second touch switch 6622 are closed, and the third touch switch 6632 works, thereby triggering the response unit 68 to alarm, thereby realizing alarm operations under different flow rates, making it convenient for medical staff to adjust according to the flow rate that the patient can accept.

[0035] Specifically, the data input module 700 can control and adjust the speed of the motor through a computer-operated controller. When the speed of the motor is slow, the shaft 45 rotates under the action of the motor, causing it to drive the impeller 44 to rotate slowly, thereby causing the flow rate of the drainage tube body 1 to be slow; when the speed of the motor is slow, the shaft 45 rotates under the action of the motor, causing it to drive the impeller 44 to rotate faster, thereby causing the flow rate of the drainage tube body 1 to be fast. The timing module 400 is used to measure time and feed back information to the cloud server 900. The cloud server 900 sends instructions to the controller to control the control unit 4 to stop working, thereby realizing precise control of the intermittent clamping of the drainage tube body 1, and can also realize precise control of the flow rate of the accumulated fluid in the drainage tube body 1, so that the flow rate of the accumulated fluid in the drainage tube body 1 is maintained at the target flow rate, thereby ensuring the safe operation of the drainage operation.
