Description
Technical field
This utility model relates to a kind of irrigation of bladder thermochemotherapy appearance.
Background technology
Bladder cancer is the urinary system common malignancy, and sickness rate occupies the first place of urinary system malignant tumor.Relapse rate is high, and postoperative has patient's recurrence of 50%～70% approximately.Different with other malignant tumor is, it has natural path urethra, and postoperative irrigation of bladder chemotherapy is a kind of effective measures that reduce tumor recurrence; Through the drug infusion chemotherapy; Make chemotherapeutic and mucous membrane of urinary bladder even contact, the part reaches active drug concentration, not only can remove the cancerous cell of leaving in the art; And may command and removing be by indiscoverable cancer in situ of naked eyes and precancerous lesion, thereby reduced the postoperative recurrence rate.Research at present shows that normal tissue cell can tolerate 47 ℃ and continue 1 h under hot conditions: and malignant cell only can tolerate 43 ℃ of lasting 1h, and 43 ℃ of lasting lh are called as the critical temperature of malignant cell irreversible lesion.And heat effect can strengthen the cytotoxicity of chemotherapeutics.The perfusion chemotherapy medicine can reach higher drug level at intracavity in the body cavity, strengthens the direct cytotoxicity to cancerous cell.The advantage of intracavity heating and intra-bladder instillation chemotherapeutics two aspects; Both bring into play collaborative GVT; But thermogenetic effect inducing tumor cell film ultrastructure changes; Improve running and the picked-up ability of cell membrane, tumoricidal metabolic process, thereby the cytotoxicity of promotion chemotherapeutics to chemotherapeutics.Therefore, utilize thermotherapy can increase the heat power effect of anticarcinogen curative effect.Combine thermotherapy and chemotherapy comprehensively, prevent and treatment bladder cancer and postoperative recurrence, can improve the clinical efficacy of bladder cancer.But medical science also can not provide irrigation of bladder thermochemotherapy instrument to come out both at home and abroad at present.
The utility model content
The purpose of this utility model is to provide a kind of irrigation of bladder thermochemotherapy appearance, has realized that perfusion chemotherapy combines with thermotherapy, has improved the irrigation of bladder chemotherapeutic efficacy, easy operating, safety, stable.
The technical scheme of this utility model is: a kind of irrigation of bladder thermochemotherapy appearance; It is characterized in that comprising three-cavity air bag catheter, thermotherapy central control system, heating cabinet, two constant flow pumps and medicinal cupping; On three-cavity air bag catheter and medicinal cupping, be equipped with temperature sensor; The thermotherapy central control system is connected with two constant flow pumps through the constant flow pump output circuit; The thermotherapy central control system is connected with heating cabinet through the heating cabinet output circuit, and the thermotherapy central control system is connected with temperature sensor with signal adjusting module through temperature collection circuit, and the thermotherapy central control system is connected with keyboard input circuit, liquid crystal display circuit, warning and power-off protecting circuit simultaneously.
This utility model has been realized the treatment of irrigation of bladder thermochemotherapy; Improve bladder chemotherapy effective percentage, the new method of bladder zone treatment is provided simultaneously, and comparatively safe; Be a kind of clinical treatment bladder cancer that can be used for, eliminate the new instrument of the subclinical focus of postoperative existence.
Description of drawings
Fig. 1 is this utility model device structure sketch map.
Fig. 2 is that this utility model thermotherapy central control system signal connects sketch map.
The specific embodiment
This utility model mainly comprises thermostatic control part and thermotherapy central control system part.
As shown in Figure 1, thermostatic control part mainly comprises heating cabinet 9, two constant flow pumps 5, three-cavity air bag catheter 3 and medicinal cuppings 8, and three-cavity air bag catheter 3 is provided with breather 4, outlet pipe 6 and water inlet pipe 7.All have temperature sensor 2 thermometrics on three-cavity air bag catheter 3 and the medicinal cupping 8, guarantee that temperature in particular range, guarantees the safety of clinical practice, realize the harmless of tumor tissues temperature accurately detected.Heating cabinet 9 is used for heating medicinal liquid; Constant flow pump 5 is used for transmitting medicinal liquid; When medicinal liquid met the demands, two constant flow pumps 5 just were input to bladder 1 to medicinal liquid, controlled two constant flow pump 5 rotating speeds by the constant flow pump output circuit that the thermotherapy central control system connects; Make flow velocity and temperature coupling, simultaneously the intracavitary therapy liquid temp is monitored and overtemperature alarm in real time.
Thermostatic control mainly is to realize through the break-make of controlling heating cabinet 9, and native system adopts the zero passage control mode, prevents on/off moment over-current shock.During work; Design temperature at first; Temperature sensor 2 with in the bladder that measures and the fluid temperature in the medicinal cupping pass to the thermotherapy central control system, later on through two constant flow pumps 5 of constant flow pump place on-off control, and control heating cabinet 9 through computing through constant flow pump interface circuit output signal; So that the medicinal liquid flow velocity and the heating power that obtain being fit to, thereby guarantee that intravesical fluid temperature remains near the design temperature.
As shown in Figure 2; Said thermotherapy central control system has the function of preserving data, Based Intelligent Control, warning and power-off protection, and the single-chip microcomputer in the thermotherapy central control system is connected with power-off protecting circuit with keyboard input circuit, liquid crystal display circuit, heating cabinet output circuit, temperature collection circuit, warning circuit simultaneously.The keyboard input circuit is used for importing the temperature value of setting and manual control system's operation; Liquid crystal display circuit is used for the running status and the time of the temperature of display setting, intravesical actual temperature, system.Single-chip microcomputer is through the clock indication of system's operation during each run; Heating cabinet 9 and two constant flow pumps 5 are controlled; While send charactron to show the temperature value of each several part in each observing and controlling process, and carries out out-of-limit judgement, when temperature is out-of-limit, starts the warning circuit alert notice.
Concrete working method
After this instrument starts; When the thermotherapy central control system makes medicinal cupping 8 inner liquid medicine temperature reach set temperature value; The thermotherapy central control system is sent signalisation constant flow pump 5; Medicinal liquid begins to get into bladders 1 through constant flow pump 5 by water inlet pipe 7, and constant flow pump 5 is used medicinal liquid extraction bladder 1 simultaneously, and the outlet pipe 6 through constant flow pump 5 is back in the medicinal cupping 8 again; The temperature sensor 2 that is arranged in bladder 1 and medicinal cupping 8 in the thermotherapy process detects its temperature in real time, after the signal condition module, sends into the thermotherapy central control system by the two paths of signals of temperature sensor 2, after analyzing and processing, preserves and demonstration; The thermotherapy central control system with two paths of signals relatively after, the temperature of heating cabinet 9 is carried out Based Intelligent Control regulates, when water temperature surpasses the temperature extremes that the user sets, system will report to the police automatically.
