Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and specifically provides a nasal balloon catheter with a pressure indication function. Background Art

[0002] Nasal packing is a commonly used method to inhibit nasal hemostasis. Current nasal hemostasis devices often focus on hemostasis function and ease of operation during the design process. There is a lack of preset and targeted solutions to problems in specific usage scenarios. For example, the device often needs to be held in hand during use, and the balloon located in the nasal cavity cannot be intuitively perceived. The only way to judge whether it is properly placed is to rely on the experience of medical staff and the feelings of the patient. This makes the device easy to fall, which can easily cause damage to the patient and increase the workload of medical staff.

[0003] CN219331779U discloses a nasal compression hemostasis balloon catheter, which places a balloon at a part of the nasal cavity that needs compression hemostasis, injects physiological saline from a water pipe to fill and expand the balloon to achieve the function of compression hemostasis, and is also provided with a nose wing fixing frame on the tube body, which can be clamped on the patient's nose wing. However, the catheter cannot monitor the pressure state of the balloon when in use, and it is difficult to adjust the pressure of the balloon according to actual use conditions during use, which affects the use effect; the nose wing fixing method reduces the patient's comfort, the fixing effect is poor, and it is impossible to solve the problem of adaptive adjustment according to the facial features of different patients to ensure the fixing effect during use. Utility Model Content

After adopting the above structure, the pressure and expansion state inside the balloon are indicated by arranging a pressure indicating device, so as to realize the visualization and controllability of the balloon use state. When in use, the pressure and expansion state of the balloon are adjusted by the display result of the indicating device, so as to avoid the poor hemostatic effect of the balloon due to too low pressure, and the pain and poor comfort of the patient when the pressure is too high.

[0005] The specific technical solutions provided by the utility model are as follows:

[0006] A nasal balloon catheter with a pressure indicating function comprises a connecting tube, the lower part of the connecting tube is connected to one side of the catheter, a balloon is arranged on the other end of the catheter, the upper part of the connecting tube is connected to the pressure indicating balloon, the upper part of the pressure indicating balloon is provided with a pressure indicating instrument, the upper part of the pressure indicating instrument is provided with a one-way valve, one end of a connecting component is fixedly arranged between the one-way valve and the pressure indicating instrument, and the other end of the connecting component is connected to an ear hook.

[0007] In the catheter adopting the above structure, the pressure indication function is realized by the pressure indicating instrument and the pressure indicating balloon. The pressure indicating balloon is connected to the side cavity of the catheter through a connecting tube. Its internal pressure and expansion state can be consistent with those of the balloon, and the expansion state of the balloon can be intuitively indicated.

[0010] After the medium (liquid or gas) is filled into the balloon catheter from the one-way valve, the medium passes through the connecting tube, the second cavity and the opening of the second cavity inside the balloon, and is filled into the balloon to prop up the balloon.

[0011] Furthermore, the ear hook is made of silicone material, which contains a metal wire to assist deformation, and the shape of the ear hook can be changed to fit the patient's ear.

[0012] Furthermore, the ear hook is also provided with a shaping strip and an adjustment groove, the adjustment groove has a depression inside, and the connecting component has a protrusion corresponding to the depression.

The pressure indicating balloon 4 can visually indicate the expansion state of the balloon 7. Figure 2 The diagram shows a dial diagram of the pressure indicating instrument 3. The pointer on the dial can indicate the pressure condition inside the balloon catheter, and further indicate the pressure condition inside the balloon 7. When the pointer is located in area ①, it indicates that the pressure inside the balloon 7 is insufficient; when it is located in area ②, it indicates that the internal pressure is appropriate; when it is located in area ③, it indicates that the internal pressure is too high. When in use, the state of the balloon 7 can be adjusted by referring to the pointer direction of the pressure indicating instrument 3.

[0032] The medium filled into the balloon catheter may be liquid or gas; when the liquid is filled into the balloon catheter, it should be ensured that the liquid level after filling is above the pressure indicating instrument 3 .

[0033] The pressure indicating instrument can be various pressure indicating devices, preferably a pressure gauge. Preferably, area ① indicates 0-100 kPa, area ② indicates 100-200 kPa, and area ③ indicates 200-300 kPa.

[0034] Preferably, the volumes of the pressure indicating balloon 4 and the indicating balloon 7 are the same.
