Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a pusher with a sponge adsorption head storage device. Background Technology

[0002] Currently, in patients with esophageal fistulas, after external medication, the fistula gradually shrinks during treatment, and fluids (such as pus, exudate, and necrotic secretions) are produced within it, requiring aspiration. Operators typically use an esophagoscope to hold a sponge suction head, then insert the sponge into the esophagus and guide it to the fistula opening. However, during this process, because the sponge suction head is in an unfolded state and has a large volume, it is prone to getting stuck and difficult to push.

[0003] Therefore, how to more conveniently deliver the sponge suction head to the esophageal fistula of the patient has become a technical problem that needs to be solved.

[0004] In addition, ensuring that the sponge adsorption head is not compressed during storage before use, thus avoiding affecting its elasticity, is also a technical problem that needs to be solved. Utility Model Content

[0027] 1. A pusher with a sponge adsorption head storage device according to this utility model, wherein the outer tube includes a tube body and a hollow storage shell, the fifth hollow part of the storage shell is connected to the third hollow part of the outer tube, the first hollow part inside the sponge adsorption head is connected to the first end of the drainage tube, the second end of the drainage tube passes through the second hollow part inside the pusher tube, and the pusher tube passes through the third hollow part of the tube body and the fifth hollow part of the storage shell. At this time, the pusher with the sponge adsorption head storage device consists of an outer tube, a pusher tube, and a drainage tube from the outside to the inside, that is, the pusher tube wraps around the drainage tube, and the outer tube wraps around the pusher tube. When using the pusher with a sponge suction head storage device, the sponge suction head is already placed inside the storage shell (i.e., the sponge suction head is already installed in the storage shell when the pusher with the sponge suction head storage device leaves the factory). The operator first uses the push tube to push the sponge suction head in the fifth hollow part of the storage shell forward (i.e. towards the first end of the outer tube) until it enters the tube of the outer tube. At this time, the sponge suction head in the third hollow part of the tube is in a compressed state. That is to say, the sponge suction head and the push tube are both in the third hollow part of the outer tube. Then, the outer tube is inserted into the patient's esophagus until the first end of the outer tube is delivered to the vicinity of the fistula. Then, the push tube is pushed forward, and the first end of the push tube pushes the sponge suction head forward until the sponge suction head is completely removed from the tube of the outer tube. The sponge suction head expands and returns to its original shape and covers the fistula, realizing the placement operation of the sponge suction head. This allows the sponge suction head to be delivered to the fistula in the patient's esophagus more conveniently. When the pusher with the sponge suction head storage device leaves the factory, the sponge suction head is already placed in the storage shell. During long-term storage, the sponge suction head in the storage shell will not be compressed before use, and the elasticity of the sponge suction head will not be affected. The pusher with the sponge suction head storage device can return to its original shape when used, and the sponge suction head can completely cover the esophageal fistula.

[0028] 2. A pusher with a sponge suction head storage device in this utility model is provided with a connecting head, a first fixing head for connecting the outer sleeve, and a second fixing head for connecting the push tube. The connecting head, the first fixing head, and the second fixing head are detachably connected. When using the pusher, the operator can better move the outer sleeve and the push tube to complete the placement of the sponge suction head in the patient's esophagus, so that the sponge suction head can be delivered to the esophageal fistula more conveniently. It can also connect the connecting head, the first fixing head, and the second fixing head during placement to fix the position between the outer sleeve and the push tube, and prevent the sponge suction head from moving accidentally in the patient's esophagus.

[0029] 3. A pusher with a sponge adsorption head storage device in this utility model uses a three-way connector. While achieving a detachable connection between the connector, the first fixing head, and the second fixing head, the third end of the three-way connector can also be used as the operating end to input liquid into the three-way connector. Utilizing the gap between the three-way connector and the push tube, and the gap between the push tube and the outer sleeve, the liquid flows to the esophageal fistula of the patient, realizing the function of adding medicine and / or flushing the fistula.

[0049] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0050] See Figures 1 to 9 In specific embodiment 1, a pusher with a sponge adsorption head storage device is provided. This pusher includes a sponge adsorption head 1, a drainage tube 2, an outer tube 3, and a pusher tube 4. The outer tube 3 includes a tube body 35 and a hollow storage shell 36. The fifth hollow portion 362 of the storage shell 36 connects to the third hollow portion 33 of the outer tube 3. The first hollow portion 11 inside the sponge adsorption head 1 is connected to the first end 21 of the drainage tube. The second end 22 of the drainage tube passes through the second hollow portion 43 inside the pusher tube 4. The pusher tube 4 passes through the third hollow portion 33 of the tube body 35 and the fifth hollow portion 362 of the storage shell 36. In this configuration, the pusher with the sponge adsorption head storage device consists of, from the outside in, the outer tube 3, the pusher tube 4, and the drainage tube 2; that is, the pusher tube 4 wraps around the drainage tube 2, the outer tube 3 wraps around the pusher tube 4, and the storage shell 36 is connected to the tube body 35 of the outer tube 3. When the pusher with the sponge suction head storage device is used, the sponge suction head 1 is already placed in the storage shell 36 (that is, when the pusher with the sponge suction head storage device is shipped, the sponge suction head 1 is already installed in the storage shell 36, and it can generally be stored for 2 years). The operator first uses the push tube 4 to push the sponge suction head 1 in the fifth hollow part 362 of the storage shell 36 forward (that is, towards the first end 31 of the outer tube) until it is inside the tube body 35 of the outer tube 3. At this time, the sponge suction head 1 located in the third hollow part 33 inside the tube body 35 is in a compressed state. That is to say, the sponge suction head 1 and the push tube 4 are both inside the third hollow part 33 of the outer tube 3. Then, the outer tube 3 is inserted into the patient's esophagus until the first end 31 of the outer tube is delivered to the vicinity of the fistula. Then, the push tube 4 is pushed forward, and the first end 41 of the push tube pushes the sponge suction head 1 forward until the sponge suction head 1 is completely removed from the tube body 35 of the outer tube 3. The sponge suction head 1 expands and returns to its original shape and covers the fistula. Next, the push tube 4 is pulled backward from the gap between the drainage tube 2 and the outer tube 3 until the push tube 4 and the outer tube 3 separate. Since the drainage tube 2 and the push tube 4 are separated, the outer tube 3 is then pulled backward until the drainage tube 2 and the outer tube 3 separate, ensuring that the sponge suction head 1 and the drainage tube 2 remain, thus completing the placement operation of the sponge suction head 1. When using the pusher with the sponge suction head storage device, it is not necessary to roll and compress the sponge suction head 1 from outside the outer tube 3 and store it inside the tube body 35 of the outer tube 3, eliminating this step. In this embodiment 1, simply pushing the push tube 4 forward to push the sponge suction head 1 achieves the forward movement and compression action of the sponge suction head 1, resulting in higher efficiency.

[0051] During the movement of the sponge suction head 1 to the esophageal fistula, the sponge suction head 1 remains compressed and housed within the third hollow portion 33 of the inner tube 35 of the outer tube 3. This minimizes the overall volume of the outer tube 3's body 35 and the sponge suction head 1, reducing the likelihood of jamming or difficulty in pushing it forward. In other words, the sponge suction head 1 can be delivered to the patient's esophageal fistula more easily. During the movement of the sponge suction head 1, because the outer tube 3's body 35 is relatively small (compared to the esophagoscope and / or the sponge suction head 1 in its unfolded state), it does not irritate sensitive nerves in the pharynx, avoiding triggering nausea or vomiting reflexes and improving patient comfort.

[0052] Preferably, the storage shell 36 and the outer sleeve 3 are coaxial, and the cross-sectional area of ​​the storage shell 36 is larger than that of the outer sleeve 3. When the push tube 4 moves forward in a straight line, the push tube 4 can move forward against the sponge adsorption head 1. The sponge adsorption head 1, which is in an expanded state inside the storage shell 36, can also be gradually compressed into a compressed state by the storage shell 36 as it moves forward. The compressed sponge adsorption head 1 moves into the tube body 35 of the outer sleeve 3. In other words, before the pusher with the sponge adsorption head storage device is used, the sponge adsorption head 1 can be well stored in the fifth hollow part 362 of the storage shell 36 and will not be compressed. This avoids the long-term compression before use affecting the elasticity of the sponge adsorption head 1, which would prevent the sponge adsorption head 1 from expanding back to its original shape during use and affecting the coverage effect of the sponge adsorption head 1 on the esophageal fistula.

[0053] Before use, the sponge suction head 1 stores the storage shell 36 in a clean and hygienic manner.

[0054] The shape of the fifth hollow portion 362 of the storage shell 36 matches the shape of the sponge suction head 1 after it is unfolded. That is, the shape of the fifth hollow portion 362 of the storage shell 36 is similar to the shape of the sponge suction head 1 after it is unfolded, or the shape of the fifth hollow portion 362 of the storage shell 36 is proportionally enlarged according to the shape of the sponge suction head 1 after it is unfolded, or the shape of the fifth hollow portion 362 of the storage shell 36 is larger than the shape of the sponge suction head 1 after it is unfolded. This is to ensure that the storage shell 36 will not press on the sponge suction head 1, and the sponge suction head 1 can be fully unfolded inside the storage shell 36 to retain optimal elasticity.

[0055] Preferably, the front section 361 of the storage shell is conical with a semi-cone angle of 20° to 40°. When the sponge adsorption head 1 in the fifth hollow part 362 of the storage shell 36 moves forward, the sponge adsorption head 1 can be gradually compressed by the front section 361 of the storage shell, which helps the compressed sponge adsorption head 1 to move into the tube body 35 of the outer sleeve 3, for example, the compressed sponge adsorption head 1 moves into the tube body 35 near the first end 31 of the outer sleeve.

[0056] Preferably, the storage shell 36 is made of a transparent material, which allows the operator to observe the condition of the sponge adsorption head 1 inside the storage shell 36 from the outside, such as whether the storage shell 36 has a sponge adsorption head 1 or whether the condition of the sponge adsorption head 1 is good (e.g., whether it is in a fully extended state). The operator can quickly select a qualified pusher for use.

[0057] Preferably, the storage shell 36 is located near the second end 32 of the outer sleeve, so that the longest tube 35 can be preserved as much as possible, and the length of the tube 35 extending into the esophagus is guaranteed.

[0058] Preferably, the pusher with a sponge adsorption head storage device further includes a connector 6, the second end 32 of the outer tube is connected to the first fixing head 5 (e.g., by glue), the second end 42 of the push tube is connected to the second fixing head 7 (e.g., by glue), the fourth hollow part 64 inside the connector 6 is sleeved on the push tube 4, the first end 41 of the push tube corresponds to the sponge adsorption head 1, and the push tube 4 is used to push the sponge adsorption head 1 out of the outer tube 3, so that the sponge adsorption head 1 expands and covers the fistula at the patient's esophageal fistula; the first end 61 of the connector is detachably connected to the first fixing head 5, and the second end 62 of the connector is detachably connected to the second fixing head 7. Before moving the sponge suction head 1 to the esophageal fistula, first connect the first end 61 of the connector to the first fixing head 5. The second fixing head 7 is temporarily not connected to the connector 6. This makes it easier for the user to hold the connector 6 with one hand and the second fixing head 7 with the other hand to push the sponge suction head 1 in the storage shell 36 forward (i.e. towards the first end 31 of the outer tube). The sponge suction head 1 is slowly compressed by the conical design of the front section 361 of the storage shell. The compressed sponge suction head 1 is moved into the third hollow part 33 of the tube body 35 of the outer tube 3 (preferably near the third hollow part 33 of the first end 31 of the outer tube). At this time, the sponge suction head 1 is in a compressed state. Then, the tube body 35 of the outer tube 3 containing the compressed sponge suction head 1 and the push tube 4 are precisely controlled to move synchronously in the patient's esophagus until the first end 31 of the outer tube is delivered to the vicinity of the fistula. The user then holds the connector 6 still with one hand, while using the other hand to hold the second fixing head 7 and move it forward to control the precision of the push tube 4's movement. This ensures that the sponge suction head 1, which has been removed from the outer tube 3, is aligned with the fistula opening and expands, completely covering the fistula opening. At this point, the second end 62 of the connector and the second fixing head 7 can be connected and fixed, achieving a relatively fixed position between the outer tube 3 and the push tube 4. That is, the push tube 4 cannot move inside the outer tube 3, and the position of the sponge suction head 1 in the esophagus is relatively stable and will not move arbitrarily. Conversely, after the sponge suction head 1 has been placed, the second fixing head 7 and the connector 6 are first disassembled and separated. The push tube 4 is then moved backward to remove it. Then, the connector 6 is moved backward, causing the connector 6 to move the outer tube 3 backward, thus removing the outer tube 3.

[0059] In this embodiment 1, the first fixing head 5 is provided with a first internal thread 53, and the first end 61 of the connector is provided with a first external thread 65. The first internal thread 53 and the first external thread 65 are connected, that is, the first internal thread 53 and the first external thread 65 realize the detachable connection between the first fixing head 5 and the connector 6; the second end 62 of the connector is provided with a second internal thread 66, and the second fixing head 7 is provided with a second external thread 73. The second internal thread 66 and the second external thread 73 are connected, that is, the second internal thread 66 and the second external thread 73 realize the detachable connection between the connector 6 and the second fixing head 7.

[0060] The outer side of the connector 6 is provided with a recessed part 67, which makes it easy for the user to grip the connector 6 and apply force to the connector 6, thereby indirectly controlling the back and forth movement of the outer sleeve 3.

[0061] In this embodiment 1, the first end 51 of the first fixing head is provided with an inner extension 56 extending radially inward, the inner extension 56 forming a first opening 57 for the outer sleeve 3 to pass through, and the second end 32 of the outer sleeve is provided with an outer extension 34 extending radially outward, the inner extension 56 and the outer extension 34 forming a snap-fit ​​connection.

[0062] When the outer tube 3 is inserted into the first opening 57, the inner extension 56 and the outer extension 34 abut against each other, connecting the first fixing head 5 and the connecting head 6. For example, by tightening the first internal thread 53 on the inner side wall of the first fixing head 5 and the first external thread 65 on the outer side of the connecting head 6, the first end of the connector and the inner extension 56 together clamp the outer extension 34, thereby achieving the connection and fixation between the first fixing head 5, the connecting head 6 and the outer tube 3.

[0063] The outer surface of the second section 55 of the first fixing head has a first raised horizontal bar 58 to increase the friction force for the operator to rotate the first fixing head 5. The second fixing head 7 is a hollow cylinder, and the push tube 4 passes through the hollow part of the second fixing head 7. The push tube 4 and the hollow part of the second fixing head 7 are connected, for example, by using glue to fix them together. The outer surface of the second fixing head 7 has a second raised horizontal bar 74 to increase the friction force for the operator to rotate the second fixing head 7. For example, a second external thread 73 is provided on the outer surface of the second fixing head 7 near the connector 6, and a second raised horizontal bar 74 is provided on the other section 72 of the outer surface of the second fixing head away from the connector.

[0064] See Figures 10 to 12 In specific embodiment 2, this embodiment 2 provides a pusher with a sponge adsorption head storage device. The difference between this embodiment 1 and embodiment 2 is that the connector 6 is a three-way connector 6, the first end 61 of the three-way connector is the output end, the output end corresponds to the first fixed head 5, the second end 62 of the three-way connector is the input end, the input end corresponds to the second fixed head 7, and the third end 63 of the three-way connector is the operation end for injecting liquid into the gap between the three-way connector 6 and the push tube 4.

[0065] In this embodiment 2, the first end 61 and the second end of the three-way connector are connected to form a hollow channel (i.e., the fourth hollow part 64) through which the push tube 4 passes. The third end 63 of the three-way connector is connected to the hollow channel. There is a gap between the push tube 4 and the hollow channel, which facilitates the movement of the push tube 4 within the hollow channel of the three-way connector 6. When the sponge adsorption head 1 is placed, the outer tube 3 is inserted into the patient's esophagus. Liquid can also be injected into the gap between the three-way connector 6 and the push tube 4 using the third end 63 of the three-way connector (i.e., the operating end). The liquid flows into the patient's esophagus through the gap between the push tube 4 and the outer tube 3, realizing the operation of adding medicine or flushing into the esophagus.

[0066] A sealing ring is provided between the outer extension 34 and the first end 61 of the tee connector. When the first internal thread 53 on the inner sidewall of the first fixing head 5 and the first external thread 65 on the outer side of the connector 6 are tightened, the first end of the tee connector and the inner extension 56 together clamp the outer extension 34 and the sealing ring. This achieves both the connection and fixation between the first fixing head 5, the tee connector 6 and the outer sleeve 3, and the sealing between the outer sleeve 3 and the tee connector 6. This ensures that when liquid is injected into the gap between the tee connector 6 and the push tube 4 using the third end 63 (i.e., the operating end) of the tee connector, the liquid will not penetrate or leak into the gap between the tee connector 6 and the first fixing head 5. This ensures that the liquid flows smoothly into the gap between the push tube 4 and the outer sleeve 3 until it reaches the patient's esophagus, avoiding unnecessary liquid loss.

[0067] The interior of the first fixing head 5 is hollow. The part of the first fixing head 5 near the first end 51 of the first fixing head is the first section 54 of the first fixing head. The first section 54 of the first fixing head is a hollow frustum shape, and the small circle of the frustum corresponds to the second end 32 of the outer tube.

[0068] The part of the first fixing head 5 near the second end 52 of the first fixing head is the second section 55 of the first fixing head. The second section 55 of the first fixing head is in the shape of a hollow cylinder, and the first internal thread 53 is provided on the inner side of the second section 55 of the first fixing head.

[0069] The first end 61 of the tee connector includes a tapered first section 68 and a cylindrical second section 69. The shape of the first section 68 matches the shape of the first section 54 of the first fixing head. The first external thread 65 is provided on the outer side of the second section 69. When the first end 61 of the tee connector is inserted into the fifth hollow part of the first fixing head 5, as the first internal thread 53 on the inner wall of the first fixing head 5 and the first external thread 65 on the outer side of the second section 69 of the tee connector are tightened, the tighter the first end of the tee connector and the inner extension 56 clamp the outer extension 34 and the sealing ring more tightly, resulting in a better sealing effect. During this process, the first section 54 of the first fixed head, which is hollow and shaped like a frustum, guides the first end of the tee connector, ensuring that the first end of the tee connector is aligned with the sealing ring and the outer extension 34. This facilitates the axial alignment of the first end of the tee connector and the inner extension 56, helping the first end of the tee connector and the inner extension 56 to achieve a better clamping effect on the outer extension 34 and the sealing ring.

[0070] The second end 62 of the tee connector has a groove 622, and a second internal thread 66 is provided on the inner side of the groove 622. The bottom of the groove 622 has an opening that communicates with the fourth hollow part 64. The outer side of the second fixing head, near the connector, is inserted into the groove 622 of the second end 62 of the tee connector. The second external thread 73 and the second internal thread 66 are tightened to connect and fix the tee connector 6 and the second fixing head 7. At this time, the push tube 4 connected to the second fixing head 7 is inserted from the middle of the groove 622 into the opening at the bottom of the groove 622, and then inserted into the fourth hollow part 64 inside the connector 6, and then into the third hollow part 33 inside the outer sleeve tube 3.

[0071] In this embodiment 2, the appendix Figure 11 See the enlarged structure of part B in the image. Figure 3 As shown.

[0072] In specific embodiment 3, a pusher with a sponge adsorption head storage device is provided. The pusher with a sponge adsorption head storage device includes a sponge adsorption head 1, a drainage tube 2, an outer tube 3, and a pusher tube 4. The outer tube 3 includes a tube body 35 and a hollow storage shell 36. The fifth hollow part 362 of the storage shell 36 is connected to the third hollow part 33 of the outer tube 3. The first hollow part 11 inside the sponge adsorption head 1 is connected to the first end 21 of the drainage tube. The second end 22 of the drainage tube passes through the second hollow part 43 inside the pusher tube 4. The pusher tube 4 passes through the third hollow part 33 of the tube body 35 and the fifth hollow part 362 of the storage shell 36.

[0073] Even without the connector 6, the first fixing head 5, and the second fixing head 7, the storage shell 36 in Embodiment 1 can still perform the function of storing the sponge adsorption head 1. The sponge adsorption head 1 can be stored in the storage shell 36 in an expanded state without being compressed. This avoids the sponge adsorption head 1 being unable to expand and return to its original shape due to prolonged compression (i.e., the elasticity of the sponge adsorption head 1 is affected), thereby affecting the covering effect of the sponge adsorption head 1 on the esophageal fistula opening.

[0074] The placement of the sponge suction head 1 in the patient's esophagus. During the movement of the sponge suction head 1 to the esophageal fistula, the sponge suction head 1 remains compressed and housed within the third hollow portion 33 of the outer sheath 3. This minimizes the overall volume of the outer sheath 3 and the sponge suction head 1, reducing the likelihood of jamming or difficulty in pushing it forward. In other words, the sponge suction head 1 can be delivered to the patient's esophageal fistula more easily. During the movement of the sponge suction head 1, because the tube body 35 of the outer sheath 3 is relatively small (compared to the esophagoscope and / or the sponge suction head 1 in its unfolded state), it does not irritate sensitive nerves in the pharynx, avoiding triggering nausea or vomiting reflexes and improving patient comfort.
