Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a spinal postoperative drainage structure. Background Art

[0002] After spinal surgery, some exudates such as blood, pus, and tissue fluid accumulate at the surgical site. Spinal drainage tubes are usually used to drain the exudates generated after 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 exudates generated after the operation can pass through the drainage tube and be discharged out of the body, preventing them from accumulating in the tissue, thereby reducing symptoms such as pain and swelling.

[0003] Specifically, on the basis of conventional drug treatment, the treatment group adopted the method of timed closing and intermittent drainage, that is, closing for 2 hours each time and opening the drainage for 5 - 10 minutes. During the opening of the drainage, professional nurses observed beside the bed. If the patient showed phenomena such as severe restlessness, severe coughing, and breath - holding and straining, the drainage tube was immediately clamped to prevent excessive drainage of cerebrospinal fluid caused by a short - term sudden increase in intracranial pressure within a short period of time, and the subsequent sudden decrease in intracranial pressure resulting in cerebrospinal fluid reflux or gas backflow into the brain. When the symptoms were stable, the drainage tube was opened again to complete the scheduled drainage.

[0004] However, in existing clinical operations, intermittent clamping of the drainage tube is achieved by using a clip to clamp the drainage tube. The clamping time control is determined by medical staff, or a timer is placed at the head of the bed to give a timed alarm when the time is up. In addition, the flow rate is controlled manually by medical staff pinching and releasing. All of the above are results obtained by medical staff based on their own experience and observation, which requires a lot of energy to monitor the clamping. If the medical staff has insufficient experience, it is easy to lead to inaccurate control, thus endangering the patient's life. Therefore, there is room for improvement in view of the above problems. Summary of the Invention

[0005] The present invention provides a spinal postoperative drainage structure, which can achieve precise control of the intermittent clamping of the drainage tube and can also precisely control 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 method is as follows:

[0006] A spinal postoperative drainage structure includes a drainage tube body having a drainage channel, and the drainage tube body is connected to an external negative - pressure drainage device;

[0007] A flow rate sensor is arranged on the drainage tube body, and the flow rate sensor is used to detect the flow rate of the accumulated fluid in the drainage channel;

[0008] A temperature sensor is arranged on the drainage tube body, and the temperature sensor is used to detect the temperature of the accumulated fluid in the drainage tube body;

[0009] 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;

[0010] 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;

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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 abut against the moving block and the pressure sensing carriage. When the moving block loses the acting force of the sensing probe, the second elastic member drives the moving block to reset.

[0020] Due to the adoption of the above technical solutions, the beneficial technical effects of the present invention are as follows:

[0021] The present invention can achieve precise control of the intermittent clamping of the drainage tube, and can also achieve precise control of the flow rate of the accumulated liquid in the drainage tube, so that the flow rate of the accumulated liquid in the drainage tube is maintained at the target flow rate, thereby ensuring the safe operation of the drainage operation;

[0022] The present invention has a timing module, and the timing module is connected to the cloud server. The cloud server can control the operation of the flow rate control module according to the information of the timing module to realize the automatic opening and closing operation of the drainage channel, without manual operation by medical staff, and the timing opening and closing is more precise;

[0023] The present invention is provided with an alarm module. Under the action of the flow rate of the accumulated liquid in the drainage tube body, the sensing probe can be pushed to contact the trigger unit, and the response unit is triggered to alarm, prompting the medical staff that the flow rate of the drainage tube body is relatively fast and measures need to be taken, thereby ensuring the safe operation of the operation.

[0047] The following describes the specific implementation manners of the present invention in conjunction with the accompanying drawings and embodiments:

[0048] It should be noted that the structures, ratios, sizes, etc. illustrated in the accompanying drawings of this specification are only used to cooperate with the content disclosed in the specification for those who are familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of the present invention. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the efficacy that the present invention can produce and the purpose that can be achieved, should still fall within the scope that the technical content disclosed by the present invention can cover.

[0049] At the same time, terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear description and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope within which the present invention can be implemented.

[0050] Example 1, in combination with Figure 1 As shown, this embodiment provides a drainage structure after spinal surgery, including a drainage tube body 1 having a drainage channel, and the drainage tube body 1 is connected to an external negative pressure drainage device; a flow rate sensor 2, which is arranged on the drainage tube body 1, and the flow rate sensor 2 is used to detect the flow rate of the accumulated liquid in the drainage channel; a temperature sensor 3, which is arranged on the drainage tube body 1, and the temperature sensor 3 is used to detect the temperature of the accumulated liquid in the drainage tube body 1; a control unit 4, which is arranged on the drainage tube body 1, and the control unit 4 is used to control the flow rate of the accumulated liquid in the drainage channel or the opening and closing of the drainage channel; a flow sensor 5, which is arranged on the drainage tube body 1, and the flow sensor 5 is used to detect the flow rate of the accumulated liquid in the drainage channel; an alarm unit 6, which is arranged on the drainage tube body 1 in a relatively movable manner, and the flow rate of the accumulated liquid in the drainage channel can trigger the alarm unit 6 to respond. The flow rate sensor 2 and the control unit 4 cooperate to be able to achieve precise control of the intermittent clamping of the drainage tube body 1, and can also achieve precise control of the flow rate of the accumulated liquid in the drainage tube body 1, so that the flow rate of the accumulated liquid in the drainage tube body 1 is maintained at the target flow rate, thereby ensuring the safe operation of the drainage surgery.

[0051] Specifically, as Figure 3 、 Figure 4As shown in the figure, the control unit 4 has a liquid inlet 41, a diversion chamber 43, and a liquid outlet 42. The liquid inlet 41, the diversion chamber 43, and the liquid outlet 42 are connected in sequence. The liquid inlet 41, the liquid outlet 42, and the diversion chamber 43 are all communicated with the drainage channel of the drainage tube body 1. A rotating shaft 45 is axially arranged in the diversion chamber 43. A plurality of impellers 44 are arranged on the rotating shaft 45. The plurality of impellers 44 are arranged at equal intervals along the circumferential surface of the rotating shaft 45. The shaft end of the rotating shaft 45 is provided with a motor for driving the rotation of the rotating shaft 45 and the impellers 44. Under the action of the motor, the rotating shaft 45 is driven to rotate, thereby driving the impellers 44 to rotate. The impeller 44 is formed with an arc surface 441 corresponding to the cavity wall of the diversion chamber 43. A film 442 is arranged on the arc surface 441. The film 442 is made of rubber material and abuts against the cavity wall of the diversion chamber 43. When the impeller 44 rotates, the film 442 forms a seal with the cavity wall of the diversion chamber 43 to prevent the cerebrospinal fluid flowing between the two impellers 44 from flowing out. And the flow rate of the cerebrospinal fluid entering the diversion chamber 43 is controlled by controlling the rotation speed of the motor, so that the flow rate of the cerebrospinal fluid in the drainage tube body 1 is maintained at the target flow rate, thereby ensuring the safe operation of the drainage operation.

[0052] Specifically, a controller is arranged in the external negative pressure drainage device. The drainage tube body 1 is formed with a drainage hole 11 for the cerebrospinal fluid to flow into the drainage channel. A liquid flow tube 12 is arranged on the tube wall of the drainage tube body 1. The liquid flow tube 12 has an inlet and an outlet. The inlet and the outlet respectively extend out of both ends of the drainage tube body 1 and are connected with external cooling and heating devices. The temperature sensor 3, the external cooling and heating devices are connected with the controller. The temperature sensor 3 monitors the temperature in the drainage tube body 1 in real time and feeds back the information to the cloud server 900. The cloud server 900 issues an instruction to the controller, and the controller controls the external cooling and heating devices to perform cooling or heating treatment on the liquid flow tube 12, so as to ensure that the temperature of the drainage tube body 1 reaches the set target range.

[0053] Specifically, in combination with Figure 8 As shown in the figure, the alarm unit 6 includes a power supply, an induction probe 62, a trigger unit, and a response unit 68. The induction probe 62 is connected to the positive pole of the power supply. The negative pole of the power supply is sequentially connected to the trigger unit and the response unit 68. The induction probe 62 is made of a conductive material. A plurality of groups of the induction probe 62 and the trigger unit are correspondingly arranged. By setting different flow rate alarm units for the cerebrospinal fluid, the alarm operation of the cerebrospinal fluid flow rate in multiple ranges can be realized.

[0054] In this embodiment, in combination with Figure 5As shown in the figure, at least three groups of induction probes 62 are provided. The three groups of induction probes 62 are connected to the positive pole of the power supply. Under the action of the accumulated liquid in the drainage channel, each group of induction probes 62 can contact the trigger unit to trigger the alarm of the response unit 68. The induction 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 pole 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 or the second probe 622 or the third probe 623 contacts the trigger unit, the response unit 68 is triggered to alarm.

[0055] Specifically, three groups of trigger units are provided corresponding to the induction probes 62. The three groups of trigger units are relatively movably arranged in the drainage channel of the drainage tube body 1. The trigger unit includes a pressure sensing carriage, a trigger member movably arranged on the pressure sensing carriage, and a touch switch. The trigger member is arranged opposite to the induction probe 62. When the induction probe 62 contacts the trigger member, the trigger member is driven to move, so that the trigger member contacts the touch switch to trigger the alarm of the response unit 68.

[0056] In this embodiment, the pressure sensing carriage includes a first pressure sensing carriage 61, a second pressure sensing carriage 63, and a third pressure sensing carriage 64. A trigger mechanism 66 is arranged on the front surface of the first pressure sensing carriage 61, the second pressure sensing carriage 63, and the third pressure sensing carriage 64. The trigger mechanism 66 includes a first trigger assembly 661, a second trigger assembly 662, and a third trigger assembly 663. The first probe 621, the second probe 622, and the third probe 623 are respectively arranged on the back surfaces of the first pressure sensing carriage 61, the second pressure sensing carriage 63, and the third pressure sensing carriage 64 corresponding to the first trigger assembly 661, the second trigger assembly 662, and the third trigger assembly 663. The structures of the first trigger assembly 661, the second trigger assembly 662, and the third trigger assembly 663 are the same.

[0057] In this embodiment, in combination with Figure 6 As shown in the figure, the first pressure sensing carriage 61 is axially arranged in the drainage tube body 1. A slider 611 is arranged on the first pressure sensing carriage 61. The drainage tube body 1 is provided with 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.

[0058] Specifically, a first elastic member is disposed between each group of the trigger units. When the trigger unit loses the effect of the liquid accumulation in the drainage channel, the first elastic member drives the trigger unit to reset. Preferably, the first elastic member is set as a first return spring 67. The first return spring 67 is disposed between the first pressure sensing carriage 61 and the second pressure sensing carriage 63, and between the second pressure sensing carriage 63 and the third pressure sensing carriage 64. When the first pressure sensing carriage 61 and the second pressure sensing carriage 63 lose the effect of the liquid accumulation in the drainage channel, the first return spring 67 drives the first pressure sensing carriage 61 and the second pressure sensing carriage 63 to reset.

[0059] Specifically, the first trigger assembly 661 includes a frame 6611 disposed on the first pressure sensing carriage 61. The 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 abut against the induction probe 62. When the induction probe 62 abuts against the trigger member, it drives the trigger member to move, so that the contact head 6613 contacts the touch switch. The first probe 621 abuts against the moving block 6616 and pushes the moving block 6616, the connecting rod 6614 and the contact head 6613 to move towards the touch switch. When the contact head 6613 contacts the touch switch, the response unit 68 gives an alarm to prompt the medical staff that the liquid accumulation flow rate is relatively fast.

[0060] 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. The induction probe 62 is provided with a first inclined surface 6211 corresponding to the second inclined surface 6616a. When the first inclined surface 6211 abuts against the second inclined surface 6616a, the movement of the trigger member is realized. The inclination angles of the first inclined surface 6211 and the second inclined surface 6616a are the same. When the inclined surfaces of the first inclined surface 6211 and the second inclined surface 6616a are completely fitted, the contact head 6613 contacts the touch switch, and the trigger response unit 68 realizes the alarm operation.

[0061] Specifically, a second elastic member is disposed on the connecting rod 6614. The two ends of the second elastic member abut against the moving block 6616 and the pressure sensing carriage. When the moving block 6616 loses the acting force of the induction probe 62, the second elastic member drives the moving block 6616 to reset. Preferably, the second elastic member is set as a second return spring 6615, and the second return spring 6615 can drive the connecting rod 6614 to realize the reset function.

[0062] Embodiment 2, in combination with Figure 7As shown in the figure, the present invention also provides a spinal postoperative drainage method, including a flow rate detection module 100, a flow rate control module 200, a flow volume detection module 300, a timing module 400, an alarm module 500, a data analysis module 800, and a cloud server 900. The flow rate and flow volume of the object to be measured in the area to be measured are detected by the flow rate detection module 100 and the flow volume detection module 300 to obtain the information of the object to be measured in the area to be measured, and the data analysis module 800 obtains the information and makes analysis data and transmits it to the cloud server 900. The cloud server 900 controls the flow rate control module 200 to maintain the flow rate of the object to be measured in the area to be measured at the target flow rate according to the obtained information;

[0063] The timing module 400 and the alarm module 500 set parameters, and the cloud server controls the timing module 400 and the alarm module 500 to work according to the set parameters.

[0064] Specifically, the cloud server 900 is set as a computer, and the computer can issue instructions to the controller and display data information. Three groups of trigger units are set, and 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 arranged corresponding to the first probe 621, the second probe 622, and the third probe 623. In specific application, under the action of the liquid accumulation flow rate, the first probe 621 connected to the first pressure sensing carriage 61 is driven to move, and the first inclined surface 6211 of the first probe 621 is completely attached to 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 perform the alarm operation.

[0065] In specific application, 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, and further realizing the alarm operation at different flow rates, which is convenient for medical staff to adjust according to the flow rate that the patient can accept.

[0066] Specifically, the data input module 700 can control and adjust the rotation speed of the motor through the computer operation controller. When the rotation speed of the motor is slow, the rotating shaft 45 rotates under the action of the motor, causing the impeller 44 it drives to rotate slowly, thereby making the flow rate of the drainage tube body 1 slow; when the rotation speed of the motor is fast, the rotating shaft 45 rotates under the action of the motor, causing the impeller 44 it drives to rotate fast, thereby making the flow rate of the drainage tube body 1 fast. The timing module 400 measures the time and feeds back the information to the cloud server 900. The cloud server 900 issues an instruction to the controller to control the control unit 4 to stop working, thereby realizing the precise control of the intermittent clamping of the drainage tube body 1, and also realizing the precise control of the flow rate of the accumulated liquid in the drainage tube body 1, so that the flow rate of the accumulated liquid in the drainage tube body 1 is maintained at the target flow rate, thus ensuring the safe operation of the drainage surgery.

[0067] Many other changes and modifications can be made without departing from the spirit and scope of the present invention. It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
