Description

[0002] At present, when acute cholecystitis occurs, the bile in the gallbladder becomes viscous due to inflammation and infection, and is easy to mix with gallbladder mucosa, inflammatory exudates, bacterial colonies, etc. to form a bile sludge, and if the patient also has gallbladder stones, a small stone plug may also appear. These plugs can block the drainage channel of the gallbladder tube or the puncture needle, causing the bile to be unable to be smoothly discharged, thereby aggravating the gallbladder swelling and infection, and even causing sepsis and other complications.

[0003] A temperature control thrombolytic device for minimally invasive puncture drainage of acute cholecystitis is mainly composed of a drainage tube, a temperature control system, and a thrombolytic drug delivery system. The thrombolytic drug delivery system is responsible for accurately delivering thrombolytic drugs to the plug site in the gallbladder. This system generally includes a drug reservoir, an infusion pump, and a delivery pipeline. The drug reservoir is used to store thrombolytic drugs. The infusion pump controls the flow rate to inject the drugs into the drainage tube through the delivery pipeline, and then releases them into the gallbladder through the side hole of the drainage tube to achieve the effect of dissolving the plug. In actual work, the doctor will set the target temperature of the temperature control system and the flow rate, dose, etc. of the thrombolytic drug delivery system according to the patient's condition, the size and location of the plug, etc. After the device is started, the parts work together to achieve the purpose of dissolving the plug and unobstructed drainage.

[0039] Working principle:

[0040] Firstly, before starting the device, the infusion tube warehouse of the infusion pump 1 is opened, and the infusion tubes preloaded with thrombolytic drugs are laid in the warehouse according to the indicated path. The infusion tubes are prevented from being twisted, folded or bent throughout the process to ensure smooth flow of the thrombolytic drugs. After the infusion tubes are installed in place, they are smoothly pulled out from the infusion tube outlet 2. At this time, the infusion tube outlet is in a natural straight state, which is ready for subsequent heat preservation and fixation. The push plate 4 in the inside of the fixing frame 3 is pushed, so that the two groups of push plates 4 drive the rubber arc-shaped plates 5 at the ends to approach each other until the two rubber arc-shaped plates 5 are completely attached and form a wrapping of the infusion tubes. The locking screw 12 is rotated, so that the end of the locking screw 12 slowly extends into the inside of the fixing frame 3 and is tightly attached to the outer surface of the push plate 4. The position of the push plate 4 is fixed by the clamping force of the locking screw 12, and the wrapping state of the rubber arc-shaped plates 5 to the infusion tubes is locked. With the attachment of the rubber arc-shaped plates 5, the heat preservation arc-shaped strip one 6 and the heat preservation arc-shaped strip two 7 are synchronously connected. The sealing cover belt 8 outside the heat preservation arc-shaped strip one 6 is wrapped around the heat preservation arc-shaped strip after connection, so as to ensure that the sealing cover belt 8 completely covers the joint gap. The magic tape one 9 and the magic tape two 10 are pressed to tightly attach and fix them. At this time, the infusion tubes are completely wrapped in the closed space formed by the two rubber arc-shaped plates 5 and the heat preservation arc-shaped strips one 6 and two 7. The preset temperature of the thrombolytic drugs in the infusion tubes is maintained by the heat insulation effect of the heat preservation arc-shaped strips, so as to avoid the influence of temperature fluctuation on the thrombolysis effect.

[0041] Second step, when the heat preservation mechanism appears wear, heat preservation effect drops or need to adapt to different specifications infusion tube, rotate the head of the limiting bolt 15 in the placement hole 17, make the limiting bolt 15 and the limiting screw hole 16 at the end of the fixed frame 3 completely separate, release the thread locking, then hold the main body of the fixed frame 3, pull out along the assembly clamping groove 13, make the end of the fixed frame 3 and the assembly clamping groove 13 of the infusion pump 1 completely separate, then the whole heat preservation mechanism can be removed, when replacing the new heat preservation mechanism, the end of the new fixed frame 3 needs to be inserted into the assembly clamping groove 13, ensure that it is installed in place, then rotate the limiting bolt 15, make it threadedly connected into the limiting screw hole 16 of the fixed frame 3, until the head of the limiting bolt 15 is attached to the bottom of the placement hole 17, the firm installation of the fixed frame 3 is completed, after replacement, the infusion tube wrapping and heat preservation fixing operation in the first step needs to be repeated, to ensure that the new mechanism is installed accurately and the heat preservation is sealed reliably;

[0042] Third step, the protective cover 18 is attached to the surface of the guide rail 19 at both ends, at this time the magnetic positioning slider 20 is inserted into the guide rail 19 through the connecting groove 21, and the fixing bolt 24 is threadedly connected in the fixing screw hole 25, at this time the installation of the protective cover 18 is completed, sometimes the parameters of the infusion pump 1 need to be adjusted during treatment, at this time the protective cover 18 needs to be pushed to expose the keys and display screen of the infusion pump 1, the operator pushes the protective cover 18, when the protective cover 18 moves to the appropriate position, the keys and display screen are completely exposed, the operator can conveniently adjust the parameters of the infusion pump 1, after the parameter adjustment is completed, in order to prevent misoperation, the protective cover 18 needs to be pushed again to cover the keys and display screen, the protective cover 18 is locked at the current position through the adsorption and fixing action of the magnetic positioning slider 20 and the guide rail 19, to avoid parameter deviation caused by collision and touch during treatment, if the parameters need to be adjusted during treatment, the above operation can be repeated, the protective cover 18 can be stopped and fixed at any position of the guide rail 19, and the operation flexibility and safety are considered, this flexible and stable design makes the protective cover 18 protect the operation safety of the infusion pump 1, and meets various needs in the actual treatment process, providing reliable protection for the minimally invasive puncture and drainage temperature control thrombolysis treatment of acute cholecystitis.
