Description

[Detailed description of the invention] Short tube cent gravity operated peritoneal cycle device technology field The present invention is in the field of medical machines that continuously feed and refill bags of peritoneal dialysis fluid.

background technique There has been a resurgence of interest in peritoneal dialysis in the nephrology community in recent years. For kidney treatment treatment method is slower than hemodialysis. The reason for this is that peritoneal dialysis uses the peritoneum, which is a shiny thin film. This method utilizes the permeability of the membrane that covers all the abdominal cavity contents to transmit human body repellent substances. It's a good thing. Using the peritoneum as a drainage organ, a sterile balanced salt bath is injected into the peritoneal cavity. and leave it for a certain residence time. During this residence time, the blood is repelled from the blood. Seeps through the membrane into the clear salt solution.

Because peritoneal dialysis is relatively slow compared to hemodialysis, or extracorporeal blood purification, the dialysis schedule is It was removed from the system and was considered effective only in terms of continuous patient treatment. Popovic in 1975 Chi and Monikrief describe a peritoneal dialysis exchange method in which 21 tons of fluid is placed into the patient's lower abdomen. It was left for 4 to 8 hours. After that, drain the fluid and put 21t of new fluid into the lower abdomen. Ta. Oleoboulos improved this method in 1977 by collecting peritoneal fluid in 21-ton bags. I put it in. This bag is rolled up and carried empty by the patient during the dwell time. patient is hospital-ready and requires only one bag connection to inject and drain fluid.

This dialysis method has been widely adopted, with more than 5,000 people currently undergoing dialysis in the United States. . For outpatients, it is called continuous ambulatory peritoneal dialysis (CAPD). Strength in hospital equipment Caution or for patients in the hospital, this method is recommended for continuous equilibrium peritoneal dialysis (CEPDI). It is called.

A major limitation of this new method is the occurrence of peritonitis in the patient and the tubular outlet of the fluid bag. The majority of peritonitis is caused by spike M'A, which involves inserting and removing the spike in the peritonitis. Feeling Great care by patients and hospital personnel is required during the spike exchange period to prevent contamination. Ru. Typically spike replacement and drainage procedures are required. This procedure in the hospital (by ζ It is effective in preventing infection in many cases.

Another mechanical method of peritoneal fluid cycle was proposed by Dias Hacksaw, and this machine The machine can be visited at night for a peritoneal fluid cycle. Continuous peritoneal transfusion by using a machine The time required to perform the analysis has been reduced to two stages, one with the machine running and the other with the machine running. Close the peritoneal tube away from the tube. These 4 machines are mechanical proportioning machines, and the sterile water is Dilute 20 times from the bath solution and mix. American Mechanical Products' machines It is gravity operated and weighs 4-8 bags above the patient's head. big drainage A tube containing 4 to 1211 tubes is inserted into the same tube and suspended under the patient's head.

Disclosure of invention Known machines for performing peritoneal dialysis have major drawbacks. Some parts of the machine are complex and each Requires resterilization after each use and uses electrical or mechanical scales to determine flow rate do.

Many alarms are expected between each actuation. Some machines have seven throats with large and long tubes. A bottle of about 1 ml - 10,000 V was suspended on the bed and connected to the drain hang under the bed. It is necessary to continue.

Additionally, a warming bag is used to warm the fluid before it enters the patient's abdomen. Outflow volume is sensitive 2 electromechanically with a weighing device? Therefore, it is necessary to measure a total of 12 feet of runoff.

Some machines are large and have a capacity of 40 lts (approximately 1.8 kgJ or more without liquid), The height is 6ft (approximately 1.8m) or more. If there is, the hang connection A′ The light part needs to be the same model as the manual clamp used for the home device CAPD. . The bag nipple or spike inlet attachment device is missing when the hang is placed in the machine. stomach.

In this case, the hang is suspended vertically at the top of the machine, with the critical entrance of the hang hanging out. ing.

A cycle machine with a short set of tubes needed to separate each bag is preferred. Ru. For example, each hang has a height of approximately 4 inches when filled. I need it for the group. Make a short tube + c tq,, compress or expand each hang A physical method is required to make the light fill and eject. bag 47! It is insufficient to create static pressure only at physical locations, ie above or below the antinode. C In order to suppress the vibration, the samurai using a piston or pressure cycle device requires a significantly large Requires force. On the other hand, there is a large force even with the weight of the bag alone, and 21 Six 1-ton bags weigh more than 12 kg. Use liquid weight to suppress each bag. The energy required for a single bag is six times that of the liquid weight of one bag.

Until now, the energy of the standard cycle machine's 2 (jt'5 volume of liquid) is When it flows into the world, it becomes a waste. The liquid weight of a gravity-operated cycle machine is determined by the liquid in a separate bag. It can be used for press-fitting. Raise the bag about 2.5 inches from the floor of the room. ft U: +60 If supported at a height of cm, sufficient, the intra-abdominal pressure is 10-20 m of water, and the patient is seated in a head or chair. This is because it is 2 to 3 ft (approximately 60 to 90 cm) and has a J of 10,000 V. The machine shown is of the type described above, using a short set of tubes and a liquid-repellent bag. No heating is required and the solution is returned to the same bag as the supply bag. This cycle machine is gravity-operated and uses the weight of bags that have already been filled with discharge numbers and unused bags. do. This cycle device is a short tube set gravity actuated peritoneal cycle device (STS). - Referred to as GPCI.

The cycle machine according to the present invention injects and discharges liquid into the human body, and has a king frame and a main frame. The i/rc sliding mount has a secondary frame with multiple shelves and is placed on each shelf. The main frame has vertically stacked trays spaced apart from each other to receive bags of liquid, respectively. The movable mounting is initially positioned at the bottom of the stack and placed in the closest tray during pickling. the bag when the secondary frame, tray, and bag contact each other downwardly; A stop device that presses the liquid against the adjacent tray, and a stop device that engages the stop device to push out the liquid. and an actuating device that performs a cycle operation of discharging and refilling the hang, and the actuating device Firstly, the stop device is released from the secondary frame to hold the adjacent trays and the second Drop the next frame and then release the stopper from the adjacent tray to remove the second frame. The tray will fall onto the shelf and the bung will no longer be suppressed, allowing the liquid to flow in by gravity. I will do it.

Another embodiment of the invention is a short tube set gravity actuated peritoneal cycle device comprising: A frame, multiple bags of fresh fluid, and multiple sizes to support one bag each. One tray and one tray each slidably mounted on the main frame to receive the tray. Vertical frames with attached surfaces and attached to the main frame hold trays with alternating hangs.

Drop the tray 46 downwards to refill the second hang 50 and repeat the process one after the other. Repeat to compress and refill other banks in sequence to complete the process.

The timing of inflow, retention, and outflow can be variably adjusted.

There is a safety mechanism against excessive inflow. That is, a predetermined amount of drained liquid is in the first hang. When the bag is not filled to the maximum, the clamp will not close and some of the inflow from the second bag will flow into the second bag. The flow is divided into the first bag and flows into the second bag. This device repeats injection and drainage sequentially, and each injection and drainage The minimum external energy required for Ru. Another variation of the device places a small heating lamp directly above the position control rod; Heat the resting bag before injection.

The Seikle machine described above was developed for injecting and expelling into the patient's abdominal cavity. However, this The device can be used to inject and drain other fluids for various medical purposes. This machine is Particularly advantageous for performing subsequent cycle peritoneal infiltration; t-'12# liquid It circulates through the patient's abdominal cavity during the patient's sleeping hours, and the remaining two enemies remain in the abdominal cavity during the day.

This type of cloth can be used for continuous equilibrium peritoneal permeation, and the liquid has a volume of 2ttt at 24 hours. This is a cycle of entering and exiting the abdominal cavity. The duration of stay in the abdominal cavity is 4 hours. cormorant.
