Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a temperature measuring probe and a urinary catheter using the temperature measuring probe. Background Art

[0002] In the medical clinical field, when the patient's condition changes, it is often necessary to measure the patient's body temperature and monitor the temperature changes at all times. However, the traditional temperature measuring probe cannot be directly inserted into the ordinary urinary catheter due to the insufficient hardness of the temperature measuring wire. As a result, the existing temperature measuring probe is often fixed in the urinary catheter to form a temperature measuring catheter. This means that if the patient has previously inserted an ordinary urinary catheter, the temperature measurement function cannot be used and the temperature measuring catheter needs to be re-placed. This practice not only increases the workload of nurses, but more importantly, it brings discomfort to patients when placing the catheter and increases the risk of urinary tract infection. At the same time, the cost of the temperature measuring catheter is higher than that of an ordinary urinary catheter, and it is a disposable consumable and cannot be reused, which also increases the economic burden on patients.

[0003] In addition, some patients do not re-place the temperature measuring catheter, but use nasal or manual measurement by nurses. The nasal temperature measurement method uses a harder material to insert into the patient's nasal cavity, which increases the discomfort of awake patients; while manual measurement by nurses does not measure the value in a timely manner and cannot observe the dynamic changes of the patient. Especially in the case of insufficient manpower, nurses may not be able to measure in time, which can easily lead to hypothermia.

[0004] Therefore, there is an urgent need for a temperature measuring probe and a urinary catheter using the temperature measuring probe. Summary of the invention
