Description

Technical Field

[0001] This utility model relates to the field of specimen perfusion technology in the preparation of human anatomical specimens, specifically to an automatic continuous perfusion device for cadaver preservation under high pressure. Background Technology

[0002] Anatomical specimens are an important part of human anatomy teaching and learning. They are prepared using sterilized and fixed cadavers. Specimen perfusion devices inject a fixative solution (such as formalin) into the cadaver under pressure to achieve sterilization and fixation, ensuring the long-term preservation of the specimen. Existing specimen perfusion instruments are mostly manually operated pressure devices, lacking pressure sensors and display devices. This makes the operation complex, laborious, and time-consuming, with poor continuity and inability to achieve the required precision. They are also difficult to use for special specimens or special liquids. Therefore, this research aims to develop a cadaver preservation high-pressure perfusion device that seamlessly integrates automatic solution preparation and high-pressure perfusion functions, providing a continuous, stable, and sufficient supply of perfusion solution. This solves the problem of discontinuous perfusion caused by manual solution addition interruptions in traditional methods, achieving truly high-pressure, automatic, and continuous perfusion. This significantly improves perfusion efficiency and uniformity. Utility Model Content

[0003] The purpose of this invention is to provide a high-pressure embalming device for corpse preservation that seamlessly integrates automatic liquid preparation and high-pressure injection functions, can continuously, stably, and adequately supply injection liquid, solves the problem of discontinuous injection caused by manual liquid addition interruption in traditional methods, and achieves truly high-pressure, automatic, and continuous injection, greatly improving injection efficiency and uniformity.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic continuous injection device for high-pressure embalming of corpses, comprising a storage tank, a reagent tank, and an automatic liquid preparation and injection device. A reagent branch pipe is provided at the bottom of the reagent tank, which is connected to a main reagent pipe via a first solenoid valve and a first flow meter. The other end of the main reagent pipe is connected to the storage tank. A water inlet pipe is also provided at the top of the storage tank, connected to a distilled water tank via a second flow meter and a second solenoid valve. The automatic liquid preparation and injection device includes a pump, a controller, and a level sensor. The inlet of the pump is connected to the storage tank via a pumping pipe, and the outlet of the pump is connected to a guide pipe via a gate valve. The outlet of the guide pipe is connected to an injection needle via a flexible hose. The level sensor is located inside the storage tank, and its upper and lower limit switches are electrically connected to the first solenoid valve, the second solenoid valve, and the controller, respectively. The lower limit switch of the level sensor is also electrically connected to the pump switch.

[0005] Furthermore, a stirrer is also installed inside the storage tank.

[0006] Furthermore, at least two medicine boxes are provided, each containing a different preservative.

[0007] Furthermore, the liquid level sensor adopts a float-type liquid level sensor.

[0008] Furthermore, both the storage tank and the medicine tank are equipped with vent pipes on their tops.

[0009] The beneficial effects of this invention are as follows: This device integrates an automatic solution preparation and high-pressure injection system. Through the linkage of the liquid level sensor in the storage tank, the solenoid valve in the reagent tank, the flow meter, and the controller, it achieves automatic preparation and replenishment of the preservative solution. When the preservative solution level drops to the minimum limit, the system automatically triggers the solution preparation program. The controller precisely controls the opening and closing of the solenoid valve and the flow meter to accurately prepare new solution according to the set concentration and inject it into the storage tank until the maximum liquid level is reached and the system automatically stops. The automatic solution preparation function of this device is seamlessly connected with the high-pressure injection system, enabling a continuous and stable supply of sufficient injection solution. This fundamentally solves the problem of discontinuous injection caused by manual solution addition interruptions in traditional methods, achieving truly high-pressure, automatic, and continuous injection, significantly improving efficiency and injection uniformity. It completely eliminates the need for frequent manual solution preparation and addition, making it particularly suitable for continuous injection operations of long-term or large-batch specimens. This device provides precise and controllable solution concentration, ensuring consistent and preset concentrations for each automatically prepared solution. This eliminates concentration errors that can occur with manual solution preparation, guaranteeing the stability and reliability of sample processing. The device also features a minimum level protection sensor, effectively preventing the pump from operating without liquid (dry burning), avoiding overheating and damage to the pump body, significantly extending equipment lifespan, and reducing maintenance costs and safety hazards.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 This utility model provides a technical solution: an automatic continuous injection device for high-pressure embalming of corpses, comprising a storage tank 1, a reagent tank 12, and a high-pressure automatic liquid preparation and injection device. A reagent branch pipe 11 is provided at the bottom of the reagent tank 12. The reagent branch pipe 11 is connected to a main reagent pipe 13 via a first solenoid valve 10 and a first flow meter 9. The other end of the main reagent pipe 13 is connected to the storage tank 1. A water inlet pipe 15 is also provided at the top of the storage tank 1. The water inlet pipe 15 is connected to distilled water via a second flow meter 16 and a second solenoid valve 14. The high-pressure automatic liquid preparation and filling device includes a pump 4, a controller 18, and a level sensor 2. The inlet of the pump 4 is connected to the storage tank 1 via a pumping pipe 3, and the outlet of the pump 4 is connected to a guide pipe 3 via a gate valve 5. The outlet of the guide pipe 3 is connected to a filling needle 8 via a flexible hose 7. The level sensor 2 is installed inside the storage tank 1. The upper and lower limit switches of the level sensor 2 are electrically connected to the first solenoid valve 10, the second solenoid valve 14, and the controller 18, respectively. The lower limit switch of the level sensor 2 is also electrically connected to the pump switch. When the preservative solution level drops to the minimum limit, the system automatically triggers the liquid preparation program. The controller 18 precisely controls the opening and closing of the solenoid valves and the flow meter to accurately prepare new liquid according to the set concentration and inject it into the storage tank 1 until the maximum liquid level is reached and the system automatically stops. This device is equipped with a minimum level protection for the level sensor, which effectively prevents the pump 4 from burning out.

[0014] The storage tank 1 is also equipped with a stirrer 17. The stirrer 17 can ensure the uniformity of the liquid preparation and prevent sediment from clogging the pump 4, the gate valve 5 and the filling pipeline.

[0015] At least two medicine boxes 12 are provided, and each medicine box 12 contains a different preservative.

[0016] Liquid level sensor 2 uses a float-type liquid level sensor. The float rises and falls with the liquid level, directly triggering an internal magnetic switch. It has no complex electronic components or easily damaged moving parts.

[0017] Both the liquid storage tank 1 and the reagent tank 12 are equipped with vent pipes on their tops. The vent pipes allow gas to escape slowly, avoiding the risk of explosion due to a sudden increase in gas pressure inside the containers.

[0018] The method of using this device is as follows:

[0019] Place the device in a stable, well-ventilated work area and connect it to the power supply; ensure that the reagent tank 12 contains sufficient preservative stock solution or other concentrated reagents that need to be prepared; ensure that the water supply pipe 15 is connected to the distilled water tank for dilution; prepare the perfusion tubing system and properly connect the perfusion needle 8 and the guide tube 3 to the blood vessels of the cadaver specimen to be processed. Set the parameters on the controller 18 (usually a touch screen or control panel), set the target perfusion pressure, and set the solution concentration; confirm that all settings are correct, the tubing connections are correct, and there are no leaks before starting the operation by pressing the "Start" or "Run" button on the controller 18.

[0020] If the initial liquid level in storage tank 1 is lower than the low level, controller 18 will first initiate the automatic solution preparation program, opening the first solenoid valve 10 at the bottom of reagent tank 12. Based on the set concentration ratio and feedback from the first flow meter 9, controller 18 precisely controls the flow rate of the concentrated reagent added to storage tank 1. Simultaneously, distilled water is added to storage tank 1 in proportion via the second solenoid valve 14 and the second flow meter 16 for mixing. When the liquid level in storage tank 1 rises to the set high level, controller 18 closes the solenoid valve, stopping the solution preparation. High-pressure infusion can then proceed. Controller 18 starts the pump 4, pressurizing the prepared solution in storage tank 1 and delivering it to the specimen through pipeline. During infusion, the liquid level in storage tank 1 will gradually decrease. When the liquid level in storage tank 1 drops to the low level, controller 18 will automatically restart the solution preparation program, replenishing storage tank 1 with newly prepared solution to the high level, ensuring an uninterrupted supply of infusion solution. If an abnormal situation occurs causing the liquid level in storage tank 1 to drop to the minimum protection level set by level sensor 2, controller 18 will immediately and forcibly stop pump 4 to prevent the pump from burning out and being damaged, and will issue an alarm to prompt the user to check. When the specimen perfusion reaches the point of complete filling and hardening of the limb or needs to be stopped, press the "Stop" button on controller 18. Throughout the entire process, from solution preparation to the end of perfusion, the user only needs to perform one-time pipeline connection and parameter settings. Subsequent solution preparation, level maintenance, pressure control, and safety protection are all automatically completed by the system, truly achieving a "one-click start, worry-free" operating experience, greatly simplifying the workflow and saving manpower and time.
