Description
Technical field
This utility model relates to medical instruments field, particularly relates to the chemotherapy of splanchnocoel malignant tumor and the medical treatment device of a large amount of concentrated ascites reinfusion treatment.
Background technology
Modern medicine finds, the transfer of splanchnocoel malignant tumor easy intracavity, recurrence, often cause a large amount of carcinous intracavity hydrops, especially human primary gastrointestinal cancers generally in postoperative 1 year recidivist be up to 90% in 80%, 4 years in 50%, two years, be lethal main cause.Chinese Medical Sciences University one attached institute Chen Jun green grass or young crops professor finds to terminate before by closedown abdominal cavity at Radical Operation of Gastric Carcinoma, soaks 10 minutes, advanced gastric carcinoma postoperative 5 years survival rates just can be made to rise to 43.3% from 23.1% with 43 DEG C of warm saline 4000ml.In order to solve aforesaid problem, existing device converts the method to medical apparatus and instruments, thus for the treatment of disease, but existing technology exists: when 1, extracting hydrops or delivering therapeutic liquid, power is inadequate, affects therapeutic effect; 2, there is filtration thorough, i.e. the problem of secondary pollution, causes unnecessary germ contamination; 3, temperature control instability and heated constant temperature effect bad; 4, when delivering therapeutic liquid is to patient body, there is temperature and be affected, thus cause therapeutic effect not reach best problem.
Summary of the invention
The purpose of this utility model is to provide a kind of extraction and transmitting power is sufficient, filter cleaning is thorough, temperature is controlled well and the perfusion unit of high insulating effect.
In order to solve the problem, this utility model provides a kind of hot perfusion unit, comprise shell, be provided with transporter, power set, defecator, heater, control device and power supply in described shell, described power supply comprises external power adapter and built-in portable power source; Described transporter, power set, defecator, heater and control device and power supply suitable; Described transporter comprises inlet pipeline and outlet conduit, and described power set comprise warm-up cycle kinetic pump and vacuum suction pump, and described defecator is molecular sieve, and described heater comprises electrical heating reactor coil and microwave applicator; Described control device comprises temperature controller, temperature indicator and controller; Described inlet pipeline and outlet conduit and heater suitable, described inlet pipeline is provided with successively defecator and vacuum suction pump, described outlet conduit is provided with warm-up cycle kinetic pump and defecator successively; Described temperature indicator is located on heater, described temperature controller and temperature indicator suitable, described power set, heater and temperature indicator and controller suitable; Described defecator is provided with dosing memorizer and waste liquid memorizer, and described inlet pipeline and outlet conduit are made up of internal layer conveyance conduit and outer isolating pipelines, form vacuum seal layer between described internal layer conveyance conduit and outer isolating pipelines.
This utility model both can be used to a large amount of cancerous effusion for the treatment of intracavity, namely reached warm-heat perfusion treatment with perfusion normal saline formation artificial ascitic fluid and prevented and treated the early stage transfer and relapse of intracavitary neoplasm; Concentration and reinfusion treatment can be carried out again to a large amount of ascites such as liver cirrhosis.
As further improvement of the utility model, described inlet pipeline and outlet conduit are provided with at least two defecators.Described shell is provided with support, and described support comprises three support columns, and described support column is cylinder, and the height of described support column and the aspect ratio of shell are 1: 3-6.The screen of described temperature indicator is 17 cun of screens, and described inner surface of outer cover is provided with heat-insulation layer.
This utility model is achieved in that according to tumor cell different from Normocellular temperature tolerance, normal cell can tolerate 47 DEG C of high temperature, and tumor cell just there will be irreversible death at 43 DEG C, when tumor cell is heated between 43 DEG C-44 DEG C, along with the growth of heat time heating time, survival rate obviously declines.When there is a large amount of hydrops of abdomen (breast) in tumor patient, vacuum suction pump is passed through by the hydrops sucking-off in abdomen (breast) by inlet pipeline of the present utility model, and by electrical heating reactor coil and microwave applicator, make hydrops heating temperatures and remain on 43.5 DEG C, abdomen (breast) intracavity is entered again by the re-injection of warm-up cycle kinetic pump, to reach the thermo-chemotherapy of tumor, in the process of imbibition and re-injection, all through defecator, first burden that can reduce heater, the second pollution avoiding antibacterial.When a large amount of ascites appears in liver cirrhosis, by defecator, the waste water leached is passed into waste liquid memorizer, and the hepatic ascites after concentrating feeds back abdominal cavity again, to reach minimizing PD, the treatment of the cirrhotic ascites Concentration and reinfusion of prompt resolution ascites.Namely realize carrying out different treatments to cancerous effusion and low Proteinaceous cirrhotic ascites on uniform machinery, and can avoid polluting and ensure that treatment liquid is not by the impact of external environment.
This utility model compared with prior art tool has the following advantages:
1, reasonable in design of the present utility model, when extracting hydrops or delivering therapeutic liquid, power foot, different pipelines is provided with the pump housing of specially joining, and ensures therapeutic effect.
2, inlet pipeline and outlet conduit are provided with filter, ensure to filter thoroughly, avoid causing unnecessary germ contamination.
3, by electrical heating reactor coil and microwave applicator, make stable temperature control, ensure heated constant temperature effect.
4, inlet pipeline and outlet conduit are provided with double-layer sealing structure, and its vacuum seal layer formed can be avoided when delivering therapeutic liquid is to patient body, and treatment liquid or rehydration temperature are affected, thus cause therapeutic effect not reach best problem.
5. this utility model is compared like product and is had more practicality, security reliability and multifunctionality.The design of instrument reduces patient's misery to greatest extent, fully takes into account the operability of medical personnel; Volume and more reasonable structure, can directly make serious symptom patients with advanced cancer obtain humane treatment and humanistic care at bedside.
6, because inlet pipeline and outlet conduit are provided with at least two defecators.Further guarantee filter effect.Because shell is provided with support, ensure the back-flow velocity of liquid and the angle of relative patient, and be suitable for various Curing circumstance, wide adaptability.Because support comprises three support columns, ensure stability, because support column is cylinder, be convenient to cleaning-sterilizing; Because the height of support column and the aspect ratio of shell are 1: 3-6.Screen due to temperature indicator is 17 cun of screens, convenient operation and be suitable for observe.Because inner surface of outer cover is provided with heat-insulation layer, further avoiding device is by externally temperature influence.
