Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a suction tube with a sponge head with side holes. Background Technology

[0002] A suction catheter is a medical device used to remove secretions, sputum, or other foreign objects from a patient's airway or trachea. It is typically made of soft materials, such as soft plastic or silicone, to ensure comfort and safety. Currently, the common suction catheters used clinically continuously extract air from the catheter using a negative pressure device to maintain negative pressure at the suction port, drawing oral secretions into the catheter through this negative pressure.

[0003] In the prior art, Chinese patent application number 202121534674.1 discloses a suction catheter for reducing oral mucosal damage, comprising an outer tube, an inner tube, and a connector. One end of the outer tube has an external suction port communicating with the inner lumen of the outer tube, while the other end communicates with the outside. One end of the inner tube is inserted into the outer tube, with a gap between the outer wall of the inner tube and the inner wall of the outer tube. The end of the inner tube inside the outer tube has an internal suction port communicating with the inner lumen of the inner tube and the inner lumen of the outer tube. The end of the inner tube outside the outer tube is connected to a suction catheter connector for connection to a negative pressure device. The connector connects the outer tube and the inner tube. During suctioning, even if the suction catheter comes into contact with the tracheal wall, the outer tube remains open to the outside, thus preventing the formation of a closed area within the inner tube and reducing the risk of oral mucosal damage due to excessive negative pressure caused by a closed area within the suction catheter.

[0004] However, the outer tube of the above-mentioned technical solutions usually has two external suction ports. When both external suction ports are in contact with sputum at the same time, the suction pressure is the greatest. However, when only one external suction port is in contact with sputum, the suction force will leak out from the other side port, which reduces the overall suction pressure and thus makes the suction effect poor. In addition, in the above-mentioned technical solutions, the outer tube and the inner tube are connected and fixed by a connector, which is not very firm. During use, the outer tube may fall off the inner tube, affecting its normal use. Therefore, in view of this, the existing structure is studied and improved to provide a suction tube with a sponge head with side holes, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a suction tube with a sponge head featuring side holes. It can utilize a single external suction hole on the sponge head, which works in conjunction with two staggered internal suction holes to improve suction efficiency. This solves the problem that in traditional tubes with two external suction holes, only one external suction hole is in contact with sputum, resulting in reduced suction pressure and poor suction effect. At the same time, the cooperation between the elastic clip and the extension, as well as the elastic protrusion, greatly improves the connection between the inner tube and the sponge head.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A suction catheter with a side-hole sponge tip includes an inner tube. One end of the inner tube is fitted with a suction catheter connector, and the other end of the inner tube is fitted with a sponge tip. One end of the sponge tip is open, and the other end is closed. The open end of the sponge tip is fixed to the outer periphery of the inner tube by a fixing clip. The other end of the inner tube has two internal suction holes, and the closed end of the sponge tip has an external suction hole. The external suction hole and the internal suction hole are staggered.

[0010] The fixing device includes a fixing frame that is fixedly sleeved on the outer periphery of the inner tube and an extension fixed to the inner side wall of one end of the sponge head. The fixing frame is hollow, and an elastic clip is fixedly connected to the outer periphery of the fixing frame. The extension is clamped and fixed between the elastic clip and the outer periphery of the fixing frame.

[0011] Furthermore, the inner wall of the fixing frame is provided with multiple opening slots, and several equidistant elastic protrusions are fixedly connected in the opening slots, with the ends of the elastic protrusions abutting against the outer surface of the inner tube.

[0012] Furthermore, a gap is provided between one end of the inner cannula located in the inner cavity of the sponge head and the inner wall of the sponge head.

[0013] Furthermore, the internal suction port is connected to the inner lumen of the internal cannula and the inner lumen of the sponge head, and the external suction port is connected to the inner lumen of the sponge head.

[0014] Furthermore, the inner wall of one closed end of the sponge head is fixedly connected to a card seat, and the card seat has a card slot. The end of the inner tube near the card seat is fixedly connected to a limit block, and the limit block is engaged in the card slot.

[0015] Furthermore, the suction catheter connector includes a connecting section fixed to one end of the internal insertion tube, one end of the connecting section is fixed and connected to a negative pressure tube connector, the top of the connecting section is fixed and connected to a branch tube connector, and a plug is provided on the branch tube connector.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution solves the problem that when only one of the two external suction holes in the traditional two external suction holes comes into contact with sputum, the suction pressure decreases and the suction effect is not good. This greatly improves the suction efficiency of the suction device.

[0019] (2) In this solution, the elastic protrusion is used to fix the bracket firmly to the inner tube by means of the elastic force generated by the elastic deformation of the elastic protrusion. When the inner tube is inserted into the sponge head after being aligned with the card seat, the extension of the sponge head is firmly clamped and fixed by the elastic clip, thereby greatly improving the connection between the inner tube and the sponge head and avoiding the phenomenon of the sponge head falling off the inner tube during use.

[0036] Example:

[0037] Please see Figure 1-5 A suction tube with a side-hole sponge tip includes an inner tube 1. A suction tube connector 2 is installed at one end of the inner tube 1. A sponge tip 3 is sleeved on the outer periphery of the other end of the inner tube 1. One end of the sponge tip 3 is open and the other end is closed. The open end of the sponge tip 3 is fixed to the outer periphery of the inner tube 1 by a fixing clip 4. Two internal suction holes 5 are opened on the outer periphery of the other end of the inner tube 1. An external suction hole 6 is opened on the outer periphery of the closed end of the sponge tip 3. The external suction hole 6 and the internal suction hole 5 are staggered.

[0038] The fixing clip 4 includes a fixing frame 401 fixedly sleeved on the outer periphery of the inner tube 1 and an extension 402 fixed on the inner side wall of one end of the sponge head 3. The fixing frame 401 is hollow, and an elastic clip 403 is fixedly connected to the outer periphery of the fixing frame 401. The extension 402 is clamped and fixed between the elastic clip 403 and the outer periphery of the fixing frame 401.

[0039] See Figure 5 The inner wall of the fixing frame 401 has multiple opening slots, and several equidistant elastic protrusions 7 are fixedly connected in the opening slots. The ends of the elastic protrusions 7 abut against the outer surface of the inner tube 1.

[0040] See Figure 2 The inner cannula 1 is located between one end of the inner cavity of the sponge head 3 and the inner wall of the sponge head 3, with a gap provided.

[0041] See Figure 1 and Figure 3 The internal suction port 5 is connected to the inner lumen of the internal cannula 1 and the inner lumen of the sponge head 3, and the external suction port 6 is connected to the inner lumen of the sponge head 3.

[0042] See Figure 4The inner wall of the closed end of the sponge head 3 is fixedly connected to a card seat 8. The card seat 8 has a card slot. The end of the inner tube 1 near the card seat 8 is fixedly connected to a limit block 9, and the limit block 9 is engaged in the card slot.

[0043] See Figure 1 The suction catheter connector 2 includes a connecting section 201 fixed to one end of the internal insertion tube 1, one end of the connecting section 201 is fixed and connected to a negative pressure tube connector 202, the top of the connecting section 201 is fixed and connected to a branch tube connector 203, and a plug 204 is provided on the branch tube connector 203.

[0044] Working principle: The fixing frame 401 is sleeved on the outer periphery of the other end of the inner tube 1, and the elastic force generated by the elastic deformation of the elastic protrusion 7 is used to firmly fix the fixing frame 401 on the inner tube 1. After the inner tube 1 is aligned with the card seat 8 and inserted into the sponge head 3, the extension 402 on the sponge head 3 is firmly clamped and fixed by the elastic clip 403, thereby enabling a quick connection between the inner tube 1 and the sponge head 3, and greatly improving the connection strength between the two, effectively preventing the sponge head 3 from falling off the inner tube 1 during use. During use, by setting a single external suction hole 6 on the sponge head 3, and cooperating with the two staggered internal suction holes 5, the problem of reduced suction pressure and poor suction effect when only one of the two external suction holes 6 is in contact with sputum in the traditional two external suction holes 6 can be avoided, thus greatly improving the suction efficiency of the suction device.
