カテーテルに関するものである。Detailed Description of the Invention [Industrial Application Field] The present invention is mainly used to indwell the esophagus 6c for drainage, temperature measurement, and pressure measurement, and to perform intraoperative management or follow-up observation, monitoring, and management after surgery and treatment. This invention relates to a medical monitor catheter for carrying out.

大する。Catheters for measuring temperatures in the esophagus, rectum, etc. have been used for a long time. There is no problem in simply measuring temperature, but if it is left in a body cavity, secretions will accumulate and will need to be drained. In addition, if other diagnostic items such as pressure measurement are required, separate dedicated drain tubes, pressure measurement tubes, etc. must be inserted and placed, making handling complicated and complicated, and requiring multiple tubes. It is necessary to insert the tube into the body cavity, which increases the pain caused to the patient.

出が必要となる問題があった。All of these devices are placed in the esophagus and have the function of measuring internal body temperature and monitoring heart sounds, lung sounds, electrocardiograms, etc.; It did not have any functions such as a monitor. On the other hand, in Japanese Patent Application Laid-open No. 60-99226, it is possible to measure internal body temperature and simultaneously drain body fluids and inject medicine, but it is not possible to measure pressure, and the drainage does not have an auxiliary tube for a sump. There was a problem with smooth drainage. Therefore, when measuring each single item, conventional catheters can be used, but when placed in body cavities such as the esophagus, secretions tend to accumulate and must be drained.

テーテルを提供することを目的としたものである。In view of the current state of medical monitor catheters, the present invention has been developed to enable not only temperature measurement within the body cavity but also pressure measurement at appropriate locations within the body cavity, and to facilitate the smooth drainage of secretions by indwelling the catheter. By having multiple functions that can be used for drug injection/cleaning, diagnosis/management of organ functions or medical conditions, etc., if necessary, it can be used for intraoperative management or postoperative and post-procedure follow-up observation, monitoring, and management, making it painless for patients. The object of the present invention is to provide a medical monitoring catheter that can be easily used without increasing the amount of damage.

付設させなくてもなんら差支えない。FIG. 1 is an example of an embodiment, which has a drainage function with a sump and a temperature measurement function. The main tube (
2), a first auxiliary pipe (3) provided in the pipe wall surrounding the main pipe (2) and serving as an air inflow passage, and a lead wire (4) for temperature measurement buried in the pipe wall. The main tube (2) has multiple openings (2) in the tube wall near the tip of the catheter.
5), and the distal end may be sealed and closed with a wall as shown in the figure, or it may be open if necessary, and the rear end is a connector section for connecting to the tube. It is convenient to have (6). First auxiliary pipe (3)
The tip has an opening (7) in the main tube (2) and branches near the rear end of the catheter, and a filter (9) is attached to the rear end of the branch tube (8).
2) Since the inside is communicated with the atmosphere through the first auxiliary pipe (3) and filter (9), it is not contaminated with bacteria etc. from the first auxiliary pipe (3) during natural drainage and suction drainage. Air flows in and relieves the negative pressure in the main tube (2) of the catheter (1) in the body cavity into which the catheter (1) is inserted, thereby preventing reduction in drainage efficiency due to adsorption and fear of adsorption damage to mucous membranes. Allows for smooth drainage. Note that the filter (9) may not necessarily be attached depending on the catheter insertion location where there is no risk of contamination.

体などが挙げられるが、これらに限定されるものではな
い。Further, the tip of the lead wire (4) is located near the tip of the catheter (1), and a temperature sensor (10) is attached thereto so that the temperature of a specific location within the body cavity can be measured. The connector (1) is attached to the rear end branch tube (11) of the catheter (1).
2), which allows temperature display and temperature recording by connecting to a monitor section. Temperature sensors used include, but are not limited to, thermocouples, thermistors, platinum resistance thermometers, and the like.

覆埋設させてもいずれの方式でも差支えない。Currently, a thermocouple or a thermistor is preferable due to cost, workability, etc. The lead wire (4) can be buried by inserting it into a pre-prepared hole in the tube wall of the catheter (1), or by embedding it during catheter tube molding. Either method may be used even if the lead wires are covered and buried at the same time.
