Description

Technical Field

[0001] The utility model relates to the technical field of esophageal pressure measuring catheters, in particular to an improved esophageal pressure measuring catheter. Background Art

[0002] The esophageal manometry catheter is a device used by staff to place the manometry catheter below the esophageal cardia during gastroscopy.

[0003] At present, there are many esophageal manometry catheters on the market, but generally, the staff directly controls the titanium clip to clamp the outer surface of the catheter by observing the changes in the gastroscope. However, the pressure measuring catheter is very smooth inside the esophagus, which causes the titanium clip to swing back and forth when the catheter moves below the esophageal cardia, causing the titanium clip and the outer surface of the catheter to loosen and fall off, thereby affecting the staff's normal clamping of the pressure measuring catheter with the titanium clip and reducing the effectiveness of the device.

[0004] Based on the above, the inventor found that: the staff directly controls the titanium clip to clamp the outer surface of the catheter by observing the changes in the gastroscope. However, the pressure measuring catheter is very smooth inside the esophagus, causing the titanium clip to swing back and forth when the catheter moves to the bottom of the esophageal cardia, causing the titanium clip and the outer surface of the catheter to loosen and fall off, thereby affecting the staff's normal clamping of the pressure measuring catheter with the titanium clip. Therefore, in view of this, the existing structure is studied and improved, and an improved esophageal pressure measuring catheter is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses an improved esophageal pressure measuring catheter, comprising a hose, a pressure sensor is fixed on the outer surface of the hose, one end of the hose is glue-connected with a ring plate, and further comprising:

[0007] A connecting rope, the outer surface of the connecting rope is fixed to one end of the ring plate, a ring sheet is fixed to the outer surface of the connecting rope, a mounting mechanism is provided on the outer surface of the ring plate, and two limiting mechanisms are provided on the outer surface of the mounting mechanism.

[0008] As a preferred technical solution of the utility model, a groove is provided at one end of the hose, a convex block is provided on the inner wall of the groove, and an outer surface of the convex block is fixed to one side of the ring plate.

[0009] As a preferred technical solution of the utility model, the installation mechanism includes:

[0010] Two fixing blocks, the outer surfaces of the two fixing blocks are fixed to the outer wall of the hose, the outer surfaces of the two fixing blocks are provided with two limiting plates, one side of the two limiting plates is provided with two card slots, the inner walls of the four card slots are provided with card blocks, and the outer surfaces of the four card blocks are fixed to the outer wall of the fixing blocks.

[0011] As a preferred technical solution of the utility model, the sizes of the inner wall cross-sectional areas of the four card slots are matched with the sizes of the outer wall cross-sectional areas of the card block.

[0012] As a preferred technical solution of the utility model, one side of the four card blocks is provided with a connecting groove, the inner walls of the four connecting grooves are matched with connecting columns, and the outer surfaces of the four connecting columns are sleeved with the inner walls of the card grooves.

[0013] As a preferred technical solution of the utility model, two concave plates are fixed to the outer walls of the four connecting columns, the inner walls of the two concave plates are glued to the outer walls of the limiting plates, the outer walls of the two concave plates are fixed with fixing plates, and one side of the two fixing plates is glued to the outer surface of the fixing block.

[0014] As a preferred technical solution of the utility model, the limiting mechanism includes:

[0015] The orifice plate has its outer surface fixed to the outer wall of the ring plate, the inner wall of the orifice plate is sleeved with a square column, one side of the square column is fixed to the outer surface of the limit plate, and the other side of the square column is fixed with a rubber plate, one side of the rubber plate is glued to the outer surface of the orifice plate.

[0016] As a preferred technical solution of the utility model, a circular groove is provided at the top of the square column, a limiting column is sleeved on the inner wall of the circular groove, and the outer surface of the limiting column is sleeved on the inner wall of the orifice plate.

[0017] The beneficial effects of the utility model are:

[0018] 1. In this scheme, the contact installation between the outer wall of the limit plate and the fixed block is controlled by gluing the ring plate and the hose, so that the inner wall of the slot opened on one side of the limit block matches the outer surface of the slot, thereby making the limit plate and the fixed block tightly connected, and the inner wall of the concave plate is glued to the outer surface of the limit plate until the outer surface of the connecting column matches the inner wall of the connecting groove, thereby effectively strengthening the stability of the connection between the limit plate and the fixed block, and facilitating the improvement of the tightness of the connection between the ring plate and the hose. Therefore, the operator uses the titanium clamp tool on the external gastroscope to hook the ring plate to ensure that the hose is stable and immobile during the pressure measurement process to prevent the hose from falling off or needing to be re-placed.

[0019] 2. This solution further improves the device's ability to stabilize the limit between the limit plate and the fixed block by using the outer surface of the limit column to fit the inner wall of the orifice plate until the bottom end of the limit column is matched with the inner wall of the circular groove opened at the top of the square column. This makes it easier for staff to control the external titanium clamp to be firmly connected with the inner surface of the ring plate, so that the titanium clamp closes and fixes the wire, ensuring that the catheter remains stable during the pressure measurement process.
