Description

Technical Field

[0001] This utility model relates to the field of equipment technology, and in particular to a system for flushing and removing blood clots and retention in the digestive tract. Background Technology

[0002] Endoscopic examination of the stomach is an important diagnostic tool. Endoscopes can provide images of the inside of the body, facilitating direct observation of the stomach's condition. For example, CN115844306A describes a trowel for assembling an endoscope and a directional rapid aspiration device for gastrointestinal blood. The trowel covers the endoscope lens and, under endoscopic guidance, moves or rotates with the lens to a suitable position to aspirate accumulated blood and clots from the gastrointestinal tract.

[0003] However, the human digestive tract has limited space, preventing the insertion of large cannulas and the simultaneous accommodation of an endoscope and a negative pressure extraction channel. In existing methods, the endoscope is inserted through a negative pressure cannula for operation. However, blood clots and retained products in the stomach can easily block the channel between the endoscope and the cannula, hindering the stable delivery of irrigation fluid and affecting the extraction of blood clots and retained products. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this utility model provides a system for flushing and removing blood clots and retentions in the digestive tract, which solves the technical problem that it is difficult to achieve a stable delivery of flushing fluid and that it is easy to affect the extraction of blood clots and retentions.

[0005] According to a first aspect of the present invention, a system for flushing and removing blood clots and retention in the digestive tract is provided. The system includes a catheter device, a fluid aspiration device, and an endoscope device. The catheter device includes a catheter assembly and an infusion connector assembly. The catheter assembly includes a main channel and an infusion channel. The infusion connector assembly is connected to the infusion channel. One of the fluid aspiration device and the endoscope device is connected to the main channel. The fluid aspiration device and the endoscope device can be used in conjunction with the catheter device to reduce operating costs.

[0006] In one embodiment, the aperture of the main channel is larger than the aperture of the infusion channel, and the main channel and the infusion channel gradually separate at the top of the catheter assembly. The catheter assembly structure is adapted to accommodate two inputs, thereby enabling independent operation of the channels.

[0007] In one embodiment, the catheter assembly is an integral structure, with the main channel and the infusion channel arranged side by side; or, the end of the infusion channel intersects and communicates with the main channel.

[0008] In one embodiment, the catheter assembly has multiple lateral holes at its end, which communicate with the main channel. The lateral holes increase the area for fluid extraction and negative pressure, reducing the local negative pressure intensity at the end of the catheter assembly and improving extraction efficiency.

[0009] In one embodiment, the catheter assembly includes an inner tube and an outer tube. The inner tube is inserted into the outer tube, and the space within the inner tube forms the main channel. An infusion channel is formed between the inner and outer tubes. The inner tube is used to connect to the aspiration device or endoscope device, and the length of the inner tube is less than or equal to the length of the outer tube. The inner and outer tubes are configured to flexibly adjust the form of the catheter assembly to adapt to different scenarios.

[0010] In one embodiment, a device connector is mounted at the tip of the catheter assembly for locking connection to the liquid aspiration device. The use of a device connector in the catheter assembly improves connection convenience.

[0011] In one embodiment, the catheter assembly is made of silicone material.

[0012] In one embodiment, the infusion connector assembly includes a quick-connect fitting for locking the infusion tubing.

[0013] In one embodiment, the infusion connector assembly includes a sealing plug for engaging with the needle of the infusion tubing for infusion.

[0014] In one embodiment, the endoscope device includes an endoscope guide tube and an endoscope probe located at the end of the endoscope guide tube. The outer diameter of the endoscope guide tube is smaller than the inner diameter of the main channel, and there is a space for movement between the endoscope guide tube and the main channel.

[0015] The technical solution provided by the embodiments of this utility model can include the following beneficial effects: The catheter assembly independently sets up the infusion channel and the main channel, so that the infusion channel can accurately deliver the flushing fluid to the observation direction of the endoscope device, improving the clarity of observation and the consistency between the flushing angle and the observation angle. The main channel can accommodate the probe part of the endoscope device, and the probe part can move and shuttle along the catheter assembly. The catheter assembly can avoid the probe part directly contacting the digestive tract, reducing discomfort to the examinee. Furthermore, connecting the fluid aspiration device after the endoscope device is withdrawn can increase the diameter of the fluid aspiration tube, avoid blockage, and improve the fluid aspiration efficiency.

Detailed Implementation

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0027] like Figures 1 to 7As shown, this utility model discloses a system for flushing and removing blood clots and retained substances in the digestive tract. The system includes a catheter device 40, a fluid aspiration device 20, and an endoscope device 10. The fluid aspiration device 20 can be a negative pressure suction device to remove blood clots and retained substances from the digestive tract. The endoscope device 10 uses existing gastroscopy equipment. The catheter device 40 serves as a medical device used in conjunction with the negative pressure suction device and the gastroscopy equipment to perform examination and flushing operations in the digestive tract, reducing usage costs.

[0028] The catheter device 40 includes a catheter assembly 41 and an infusion connector assembly 45. The catheter assembly 41 is a tubular structure made of flexible or soft material to bend with the curves of the digestive tract. Preferably, the catheter assembly 41 is made of silicone material.

[0029] The catheter assembly 41 includes a main channel 42 and an infusion channel 43. An infusion connector assembly 45 is connected to the infusion channel 43. One of the aspiration device 20 and the endoscope device 10 is connected to the main channel 42. The main channel 42 and the infusion channel 43 adopt two separate channel structures, which can function independently but also point to the same examination and flushing position. The catheter assembly 41 independently sets up the infusion channel 43 and the main channel 42 so that the infusion channel 43 can accurately deliver the flushing fluid to the observation direction of the endoscope device 10, improving the clarity of observation and the consistency between the flushing angle and the observation angle.

[0030] The main channel 42 can accommodate the probe portion of the endoscope device 10, which can move and shuttle along the catheter assembly 41. The catheter assembly 41 can prevent the probe portion from directly contacting the digestive tract, reducing discomfort to the patient. Furthermore, the endoscope device 10 can be withdrawn and then connected to the aspiration device 20, which can increase the diameter of the aspiration tube, avoid blockage, and improve aspiration efficiency.

[0031] Preferably, the orifice diameter of the main channel 42 is larger than that of the infusion channel 43, and the main channel 42 and the infusion channel 43 gradually separate at the top of the catheter assembly 41. The infusion channel 43 is used to introduce flushing fluid, and its diameter is controllable and adjustable. The main channel 42 and the infusion channel 43 form a bifurcated structure at one end of the catheter assembly 41, and the main channel 42 and the infusion channel 43 can be independently connected to their respective devices. The other end of the catheter assembly 41 is brought together or intersects, thereby realizing negative pressure suction and flushing fluid flushing.

[0032] Specifically, the catheter assembly 41 is a single-piece structure, with the main channel 42 and the infusion channel 43 arranged side by side. The main channel 42 and the infusion channel 43 are two channels arranged side by side to form a porous tube structure, which can be integrally molded.

[0033] Optionally, the end of the infusion channel 43 intersects and connects with the main channel 42 to reduce the size of the catheter assembly 41 inserted into the digestive tract. Furthermore, the infusion channel 43 can deliver flushing fluid from the side to the position where it intersects with the main channel 42, improving the accuracy of flushing without affecting the operation of the aspiration device 20.

[0034] In a preferred embodiment, the end of the catheter assembly 41 is provided with a plurality of lateral holes 46, which communicate with the main channel 42. The plurality of lateral holes 46 are distributed at the end of the catheter assembly 41 in multiple rings, with each ring containing a plurality of lateral holes 46. For example, the lateral holes 46 may be arranged in two, three, four, or five rings. Preferably, the distribution area of ​​the lateral holes 46 extends a predetermined length from one end of the catheter assembly 41 to the other, thereby enabling the lateral or apical aspiration of fluids, blood clots, and retained products.

[0035] In one embodiment, the catheter assembly 41 is a single tube, with the main channel 42 and the infusion channel 43 being two channels distributed within the catheter assembly 41, forming an integral structure.

[0036] like Figure 5 As shown, in another embodiment, the catheter assembly 41 includes an inner tube 411 and an outer tube 412. The inner tube 411 is inserted into the outer tube 412, and the space of the inner tube 411 forms a main channel 42. An infusion channel 43 is formed between the inner tube 411 and the outer tube 412. The inner tube 411 and the outer tube 412 constitute an independent tube structure, and the two are inserted and fitted together or close together to form the main channel 42 and the infusion channel 43.

[0037] like Figures 1 to 7 As shown, the inner tube 411 is used to connect the aspiration device 20 or the endoscope device 10. The aspiration device 20 or the endoscope device 10 passes through the inner tube 411, thus facilitating independent connection and fixation. The length of the inner tube 411 is less than or equal to the length of the outer tube 412, enabling the flushing of the area in front of the endoscope device 10 with the flushing fluid. When the aspiration device 20 is running, the outer tube 412 expands the suction area and the fluid is drawn out from the inner tube 411, thereby improving the ease of extraction of fluids, blood clots, and retained products.

[0038] To facilitate connection to the aspiration device 20 or the endoscope device 10, a device connector 44 is installed at the top of the catheter assembly 41. The device connector 44 is used to lock the connection to the aspiration device 20. The device connector 44 can be a screw connector to connect to the negative pressure connector of the aspiration device 20. Alternatively, the device connector 44 can be a plug structure that plugs into the negative pressure connector of the aspiration device 20 for quick connection.

[0039] The infusion connector assembly 45 is used to connect the infusion device 30, which can be configured as a container for physiological saline, gastrointestinal flushing fluid or other liquids. The infusion device 30 delivers liquid to the catheter assembly 41 through the infusion channel 43 to achieve the effect of flushing the designated area.

[0040] Optionally, the infusion device 30 is connected to the catheter assembly 41 via an infusion tube 31. The infusion connector assembly 45 includes a quick-connect fitting for locking the infusion tube 31. The infusion tube 31 is fitted onto the connecting end of the quick-connect fitting, and then the quick-connect fitting locks the outer periphery of the infusion tube 31 using a snap or clamp to achieve rapid locking. The infusion tube 31 is easy to fix and remove, improving the reusability of the device.

[0041] Optionally, the infusion device 30 is connected to the catheter assembly 41 via an infusion tube 31 and a fitting needle to form a plug-in input. The infusion connector assembly 45 includes a sealing plug for engaging with the fitting needle of the infusion tube 31 for infusion. The end of the infusion tube 31 is connected to a needle, which is inserted into the sealing plug to allow liquid to enter the catheter assembly 41. Optionally, the sealing plug may be made of rubber.

[0042] The endoscope device 10 is a conventional gastroscopy device. The endoscope device 10 includes a endoscopic catheter 11 and an endoscopic probe 12 located at the end of the endoscopic catheter 11. The outer diameter of the endoscopic catheter 11 is smaller than the inner diameter of the main channel 42, and there is space for movement between the endoscopic catheter 11 and the main channel 42. The endoscopic probe 12 extends into the end of the main channel 42, and the endoscopic catheter 11 can move within the main channel 42, enabling movement of the catheter assembly 41 and allowing for flexible multi-angle examinations, thus facilitating operation.

[0043] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
