Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only used as examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 6, a flush-free toilet for a defecation radiography comprises a housing 1, and further comprises: a waste collection device 4, a contrast agent injection device, a thigh angle adjustment device and a control module 5. The control module 5 is installed in the housing 1, electrically connected to the excreta collecting device 4, electrically connected to the contrast agent injection device, and electrically connected to the thigh angle control device.
The thigh angle adjusting device is arranged opposite to the contrast agent injection device and is hinged with the shell 1 and used for adjusting the angle of the thigh and the shank of the patient. The thigh angle adjusting device includes: a support bar 21, a connecting bar 22 and a first drive motor 23. At least two support rods 21 are installed on the housing 1, extend toward the contrast medium injector, and are hinged to the housing 1. The connecting rod 22 is installed between the support rods 21 and fixedly connected with the support rods 21. A first driving motor 23 is installed in the housing 1 and electrically connected to the control module 5 for driving the support rod 21 to rotate around the hinge.
The existing closestool is in a sitting toilet form, but the best position of a patient when the patient excretes needs to be in a squatting toilet mode, the squatting toilet posture is favorable for relaxing anal sphincter muscles, the radiography examination is favorably carried out, and the radiography misguidance is reduced. However, the squatting position cannot be adopted during the contrast agent injection process, because the squatting position can cause the contrast agent to flow out and not to well enter the rectum. The thigh angle bar device of the present application can be adjusted in angle. The patient sits on the thigh adjustment device, which is now level with the ground when the contrast agent injection is required. When a patient needs to defecate, the control module 5 controls the first driving electrode to drive the supporting rod 21 to rotate, and the end part of the supporting rod 21 faces downwards, so that the patient is converted into a squatting position from a sitting position. Considering that some patients are older, or the legs are relatively stiff, and the patient is difficult to squat or has unstable body after squatting, the supporting rod 21 can also support the patient so that the patient cannot fall down due to leg problems or balance ability problems.
A contrast agent injection device is mounted on the rear wall of the housing 1 for injecting a contrast agent into a patient. The contrast agent injection device includes: a contrast agent storage tank, an injection head 32, a mechanical arm 31 and a high pressure water pump 34. A contrast agent storage tank is installed in the housing 1 for storing contrast agent. One end of the mechanical arm 31 is rotatably connected to the housing 1 and electrically connected to the control module 5. A high pressure water pump 34 is mounted in the housing 1 and is electrically connected to the control module 5 for pumping contrast media into the injector head 32.
As shown in fig. 1 and 3, the injection head 32 is mounted at the other end of the robot 31, fixedly connected to the robot 31, and electrically connected to the control module 5. The injection head 32 includes: a table-like protective shell 321, a disposable syringe, a first pressure sensor 3214, a second pressure sensor 3213, a fluorescence sensor 3212, and a push-fire device. The lower surface of the table-like protective case 321 is fixedly connected to the other end of the robot arm 31. A through hole is formed in the table-shaped protective shell 321, the through hole penetrates through the upper surface and the lower surface of the table-shaped protective shell 321, and a first edge 3211 is arranged at an opening of the upper surface. The first pressure sensor 3214 is attached to the upper surface of the table-like protective case 321, and is electrically connected to the control module 5. The second pressure sensor 3213 is mounted on an inner wall of the first edge 3211 and electrically connected to the control module 5. The fluorescence sensor 3212 is attached to the table-like protective case 321, and is electrically connected to the control module 5.
As shown in fig. 5, the disposable syringe is mounted on the table-shaped protective case 321 to abut against the outer surface of the table-shaped protective case 321. The disposable syringe comprises: an isolation diaphragm 3221, a connection structure 3224, an injection nozzle 3223, and a valve 3222. The isolation film 3221 is a soft film, and is in contact with the outer surface of the table-shaped protective case 321, and has a through hole in the middle. The connecting structure 3224 is a cylinder without a cover, and is installed in the middle of the isolating membrane 3221, the edge of the opening is fixedly connected with the isolating membrane 3221, and a through hole for the injection nozzle 3223 to pass through is formed in the bottom surface. One end of the injection nozzle 3223 passes through the connection port for insertion into the anus of the patient, and is slidably connected to the connection structure 3224. The valve 3222 is mounted in the injection nozzle 3223 with an opening in the same direction as the opening of the connecting structure 3224.
The injection device is mounted in the through hole, and abuts against the inner wall of the table-shaped protective shell 321 and the first edge 3211. The injection device includes: a first solenoid valve 3233, a catheter 323, a liquid through hole 3231, a second solenoid valve 3232, a balloon 324 and a spring 327. The first solenoid valve 3233 is in communication with the contrast reservoir and is electrically connected to the control module 5. One end of the liquid guide tube 323 communicates with the first solenoid valve 3233. The liquid passage hole 3231 is a through hole opened in the liquid guide tube 323 near the first solenoid valve 3233. The second solenoid valve 3232 is installed at the other end of the catheter 323 and electrically connected to the control module 5. The balloon 324 is sleeved on the catheter 323, and both ends of the balloon are hermetically connected with the catheter 323 and communicated with the inner strand of the catheter 323. The sheath 325 is sleeved outside the balloon 324 and is connected with the balloon 324 in a sliding way. The spring 327 is installed between the sheath 325 and the table-shaped protective shell 321, and has one end abutting against the first edge 3211 and the other end fixedly connected to the end of the sheath 325. The sheath 325 is provided with a ring 326 at the contact end with the spring 327, one end of the ring 326 is fixedly connected with the sheath 325, the diameter of the ring 326 is smaller than the diameter of the spring 327 and larger than the diameter of the catheter 323, and the diameter of the ring 326 is the same as the diameter of the other end of the injection nozzle 3223.
In the process of injecting the contrast agent into the patient, firstly, the medical staff is required to smear fluorescent substances at the anus position of the patient, which is beneficial to finding the anus position of the patient faster by the contrast agent injection device, so a fluorescence sensor 3212 is installed on the table-shaped protective shell 321 and used for collecting the position of fluorescence, the anus of the patient is preliminarily positioned, then the control module 5 controls the mechanical arm 31 to move, so that the injection head 32 reaches the position near the anus of the patient, then the pressure collection is carried out through the first pressure sensor 3214, of course, the first pressure sensors 3214 are multiple, and the position of the anus of the patient is finally determined by analyzing the pressure conditions at different positions of the table-shaped protective shell 321. Finally, the control module 5 controls the high pressure water pump 34 to deliver contrast media to the injector device, which injects the contrast media into the patient.
In view of cross-contamination and the difficulty of sterilizing the device, a disposable syringe compatible with the injector device is also designed in this application, mounted on top of a table-like protective case 321. In use, the isolation diaphragm 3221 covers the upper surface of the table-shaped protective shell 321, so as to prevent the table-shaped protective shell 321 from directly contacting the skin of the patient, and since the isolation diaphragm 3221 is soft, the pressure acquisition of the first pressure sensor 3214 is not hindered. Before injecting the contrast agent, the medical staff arranges the disposable syringe on the table-shaped protective shell 321, places the connecting structure 3224 at the opening of the through hole of the table-shaped protective shell 321, and sleeves the other end of the injection nozzle 3223 on the injector catheter 323.
After the position of the anus of the patient is confirmed, the control module 5 controls the high-pressure water pump 34 to work, so that the contrast agent is pumped into the catheter 323, at the moment, the first electromagnetic valve 3233 is in a conducting state, the second electromagnetic valve 3232 is in a closing state, so the contrast agent can flow into the air bag 324 through the liquid through hole 3231, the contrast agent in the air bag 324 is more and more increased along with the work of the high-pressure water pump 34, the air bag 324 is expanded, the sheath 325 is pushed upwards by the expansion of the air bag 324 along with the expansion of the air bag 324, and the spring 327 is compressed. During the process of moving up the sheath 325, the ring 326 of the sheath 325 contacts the end of the injection nozzle 3223 and pushes the injection nozzle 3223 upward, so that the injection nozzle 3223 comes out of the table-shaped protective case 321 and is inserted into the anus. When the pressure of the spring 327 on the first edge 3211, which is acquired by the second pressure sensor 3213, reaches a certain threshold, the control module 5 controls the first electromagnetic valve to close, stops the operation of the high-pressure air pump, and opens the second electromagnetic valve 3232, at this time, the contrast medium flows into the injection nozzle 3223, and the blocking of the valve 3222 is cleared to inject the contrast medium into the patient, and in the contrast medium injection process, because the pressure of the balloon 324 is reduced, the sheath 325 starts to fall back under the action of the spring 327, so that the contrast medium can be injected into the patient at a stable pressure, and the contrast medium can be better distributed in the rectum of the patient. And simultaneously, the injected contrast agent can be better quantified by the arrangement. Wherein the valve 3222 arranged in the injection nozzle 3223 is used for preventing the contamination of the device arrangement by substances in the anus after the injection nozzle 3223 enters the anus.
