Description

Technical Field

[0001] The invention relates to the technical field of drainage tubes, and in particular to a novel anti-blocking tube drainer. Background Art

[0002] The negative pressure drainage tube currently used, in order to smoothly guide the pus, blood, and liquid accumulated between human tissues or in the body cavity to the outside of the body, when the negative pressure drainage tube is introduced into the body cavity, the auxiliary part of the drainage tube is often sutured to the surface of human skin. Of course, this can effectively prevent the drainage tube from sliding, dislocating or shifting. However, once the time is slightly longer (about 5-7 days), the pus, blood, liquid, etc. in the body cavity will block the entrance of the drainage tube. In particular, when the condition is relieved, the new granulation tissue (commonly known as new meat) has grown into the drainage tube along the pressure gradient difference. At this time, the removal of the drainage tube can only be a forced operation (forcibly separating the new granulation tissue, new blood vessels and fibroblast tissue on both sides of the drainage tube), which will inevitably cause secondary damage to the patient and increase the patient's pain. Clinically, sometimes even another operation has to be performed to remove the negative pressure drainage tube.

The connecting part is a long rod, and a spring is sleeved on the sleeve part and arranged in a core spring limit sleeve. The core spring limit sleeve limits the axial movement of the sleeve part, and the assembly part extends out of the main hose; the pipe cap is sleeved on the assembly part and fixedly connected to the assembly part, and the pipe cap is movably sleeved on the outside of the mounting part of the main hose. At this time, the pipe cap is an operating handle, which is manually driven;

[0011] Furthermore, the core spring limiting sleeve is a split structure with upper and lower parts, and is combined by a slot and a bayonet, and an arc groove is opened between the parts, and the arc grooves are merged to form a limiting circular groove, and the limiting circular groove axially limits the sleeve connection part of the tube core.

[0012] Furthermore, a strip groove is provided in the middle of the assembly portion to form a U-shaped structure, and mounting posts are provided on both sides. Meanwhile, a mounting through hole is provided on the pipe cap, and the mounting through hole corresponds to the mounting post one by one for coordinated installation.

[0015] After adopting the above structure, the beneficial effects of the present invention are:

[0016] 1. The present invention can easily clean the granulation tissue that has excessively proliferated and entered the lumen; the rotation, forward and backward movement of the tube core, and the spoon-like structure of the slightly rounded and slightly protruding front side and the flattened rear side of each synapse in the movement make it more convenient to scoop up liquid secretions, etc., and solve the problem that thick blockages are difficult to discharge. The synapses on the tube core can scrape off the excessively proliferated granulation tissue that has entered the lumen and discharge thicker bloody secretions, etc.; it effectively avoids the granulation tissue that has excessively proliferated and entered the lumen, and the dilemma of the formation of fibroblast scar tissue hyperplasia and the connection of the lumen with the body tissue over time, thereby avoiding the difficulty of extubation; therefore, the use of the drain avoids unnecessary extubation damage, reduces the possibility of secondary damage in extubation surgery, etc., greatly alleviates the patient's pain, and reduces the risk of re-operation to remove the tube.

[0017] 2. The connecting part of the present invention is a bulging structure, so that a large amount of foreign matter drawn out by the tube core pulling operation can be temporarily stored and buffered, so as not to form excessive pressure and obstruction instantly during the operation, or even form the possibility of backflow. This solves the obstacles that may be encountered in unblocking the pipe and ensures the smooth progress of the aforementioned unblocking work.

[0018] 3. The drainage part of the present invention is a plurality of ball-like structures, which is conducive to individual cutting. This structure can facilitate users to cut different lengths for use, and the nodule-like structures of the main hose and the tube core match each other, so it is easier to achieve an ideal match after cutting, which is convenient for individual cutting of suitable lengths for different patients.

[0019] 4. The synaptic structure at the front of the tube core of the present invention is rounded and slightly protruding on the front side, which is fuller; the back side is flat and smoother, and the overall structure is similar to a spoon. When the tube core moves forward and backward, additional pulling force is generated, which is very beneficial for the discharge of secretions or other foreign matter.

[0020] 5. The present invention greatly reduces the requirements on material properties, does not require overly precise parts transfer, and significantly reduces the requirements on material compressive strength, tensile strength, hardness, etc. Existing medical silicone materials can meet production requirements, and the economic cost of materials is greatly reduced, allowing the drain to enter the market to serve the public, play a role in clinical practice, reduce patient pain, and become increasingly feasible.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Example 1

[0037] See also Figure 1-7 A novel anti-blocking pipe drainer comprises a main hose 1, a pipe core 2, a spring 3, a pipe cap 4 and a core spring limiting sleeve 5; the main hose 1 comprises a drainage portion 11 at the front section, a connecting portion 12 in the middle and a mounting portion 13 at the rear section, a plurality of drainage holes 14 are provided on the drainage portion 11, a lead-out hose 15 is provided in the connecting portion 12, a core spring limiting sleeve 5 is provided in the mounting portion 13, and a spring 3 is provided inside the core spring limiting sleeve 5; the pipe core 2 is inserted into the main hose 1 and performs axial and circumferential movement, the pipe core 2 comprises a scraping portion 21, a connecting portion 22, a sleeve portion 23 and an assembly portion 24 from front to back, the scraping portion 21 is a segmental saturated The structure is full of nodules, and a circular synapse 25 is arranged at each nodule. The top of the synapse 25 is slightly rounded and slightly protruding, and the bottom is flat, and corresponds to the position of the drainage holes 14 one by one, and is slightly lower than each drainage hole 14. The connecting part 22 is a long rod, and the spring 3 is sleeved on the sleeve part 23, and is arranged in the core spring limit sleeve 5. The core spring limit sleeve 5 limits the axial movement of the sleeve part 23, and the assembly part 24 extends out of the main hose 1; the pipe cap 4 is sleeved on the assembly part 24 and fixedly connected to the assembly part 24, and the pipe cap 4 is movably sleeved on the outside of the mounting part 13 of the main hose. At this time, the pipe cap 4 is an operating handle, which is manually driven;

[0038] Specifically, through the rotation, forward and backward movement of the tube core 2, and the front side of each synapse 25 in motion is slightly rounded and slightly protruded, and the back side is flat, and the spoon-like structure is convenient for scooping (see Figure 5 ) solves the problem of thick blockages being difficult to discharge. The synapses on the tube core can scrape off the excessively proliferating granulation tissue that enters the lumen and discharge thicker bloody secretions. It effectively avoids the excessive proliferation of granulation tissue entering the lumen, which leads to the formation of fibroblast scar tissue hyperplasia and the connection of the lumen with the body tissue over time, thereby avoiding the difficulty in tube removal. Therefore, the use of this drain avoids unnecessary tube removal injuries, reduces the possibility of secondary injuries such as tube removal surgery, greatly alleviates the patient's pain, and reduces surgical risks.

[0039] The synapses 25 are all facing the corresponding drainage holes 14, and there is a slight deviation between the positions of the two to prevent the tube core from being stuck in the side opening; if necessary, redundant side protrusions can be appropriately added to limit the tube core and reduce the possibility of the tube core being stuck at the side; the synapses 25 are arranged in groups of two, symmetrically, and each group is staggered to facilitate liquid drainage.

[0040] In order to prevent the liquid from flowing out, an elastic sleeve 8 (equivalent to a clamp) is provided between the connecting portion 12 and the mounting portion 13 to intercept the flow during non-operation time (see Fig.10 ) to prevent the liquid from flowing out; when working, just take off the cover;

[0041] During use, the user's body movements may cause the body to bend, which may cause the drainage device to fold and lead to drainage failure. Therefore, a high-toughness guide wire or a spiral metal spring can be axially arranged on the inner wall of the main hose 1 and the inside of the tube core 2 to prevent the drainage device from being folded and damaged.

[0042] The connecting portion 22 is a long rod, and the connection with the sleeve portion 23 is a conical transition, which is used to cooperate with the core spring limit sleeve 5 (see Figure 6 ), utilizing the left and right limiting activities of the sleeve portion 23.

[0043] The flow diverter further includes a semi-automatic driving structure 6 and an automatic driving structure 7 according to the driving mode.

[0044] In this embodiment, the diameters of the drainage portion 11, the connecting portion 12 and the mounting portion 13 of the main hose 1 are successively larger, and the connecting portion 12 is a bulging structure. The diameters of the front and rear ends of the main hose are successively larger, which is beneficial for draining the liquid; the connecting portion 12 is a bulging structure, so that a large amount of foreign matter drawn out by the tube core pulling operation can be temporarily stored and buffered, so that excessive pressure and obstruction are not formed instantly during the operation, and even the possibility of reflux is formed, which solves the obstacles that may be encountered in clearing the blocked pipe and ensures the smooth progress of the above-mentioned clearing work.

[0045] In this embodiment, the drainage part 11 is a hollow hose with several ball-like structures with holes. The drainage part 11 is composed of several ball-like structures with adjacent ends, which is conducive to individual cutting; this structure can facilitate users to cut different lengths for spare use, and the nodule-like structures of the main hose and the tube core match each other, so it is easier to achieve an ideal matching degree after cutting, which is convenient for individual cutting of suitable lengths for different patients.

[0046] In this embodiment, a plurality of positioning and mounting holes 16 are provided on the mounting portion 13, and a plurality of positioning and mounting protrusions 51 are also provided on the outside of the core spring limiting clamp 5, and the positioning and mounting protrusions 51 are installed in a one-to-one correspondence with the positioning and mounting holes 16. The core spring limiting clamp 5 can be positioned and installed by the cooperation between the positioning and mounting protrusions 51 and the positioning and mounting holes 16, thereby facilitating assembly and improving production efficiency.

[0047] In this embodiment, the connecting part is a slender straight rod or a slender spiral rod structure; the slender straight rod is easy to process and reduces costs; the slender spiral rod is elastic, easy to bend, and not easy to break; the two structures can be determined according to needs, but are not limited to the above two structures.

[0048] In this embodiment, the core spring limit clamp 5 is a split structure with upper and lower parts, and is combined with a clamping groove and a bayonet, and an arc groove 52 is provided between the parts, and the arc grooves are combined to form a limit circular groove, which axially limits the sleeve part 23 of the tube core 2. The split structure of the core spring limit clamp 5 facilitates the installation of the sleeve part 23 and the spring 3; the limit circular groove limits the sleeve part 23 to the left and right, that is, limits the forward and backward movement of the tube core 2, ensuring that it is within the normal working range.

[0049] In this embodiment, a strip groove 26 is provided in the middle of the assembly portion 24 to form a U-shaped structure, and mounting posts 27 are provided on both sides, and mounting through holes 41 are provided on the pipe cap 4, and the mounting through holes 41 correspond to the mounting posts 27 one by one for coordinated installation. When the assembly portion 24 and the pipe cap 4 are installed, due to the presence of the strip groove 26, the assembly portion 24 can be squeezed, so that the assembly portion 24 can be more conveniently inserted into the pipe cap 4, and at the same time, the assembly portion 24 is positioned and installed through the mounting through holes 41 and the mounting posts 27, and this method can improve assembly efficiency.

[0050] Working principle of the present invention:

[0051] 1. During drainage: When the main hose 1 of the drainage device is implanted in the human body for drainage, secretions, purulent and bloody fluids, etc., enter the main hose from the drainage hole 14, gather and buffer at the connecting part 12 of the bulging structure, and then drain to the external interface drainage bag or negative pressure ball, etc. through the outlet hose 15.

[0052] 2. During cleaning: including cleaning residual secretions, purulent and bloody fluids in the lumen, and cleaning excessively grown granulation tissues in the lumen, the operator first removes the outflow restriction sleeve to allow the tube cap 4 (operating handle) to obtain freedom (free movement); then holds the drain body with one hand and the tube cap 4 with the other hand, and starts to move forward, backward, and rotate within the prescribed freedom. The moving synapses 25 scrape off the excessively proliferating granulation tissues in the lumen and discharge thicker bloody secretions, thereby removing residual secretions, purulent and bloody fluids in the lumen, and the excessively proliferating granulation tissues that have been cleaned.

[0053] Example 2

[0054] See also Figure 8, the semi-automatic driving structure 6 replaces the operating handle, including a shell (not shown in the figure), a spring assembly 61 is arranged in the shell, the spring assembly 61 is driven by a spring knob 62, an eccentric wheel 63 is arranged on the rotating shaft of the spring assembly 61, the outer ring of the eccentric wheel 63 is an arc groove structure, and the tail end of the assembly part of the tube core 2 is against the inner ring. The other structures of the semi-automatic driving structure 6 are consistent with those of the embodiment 1, and only the driving mode is different; the semi-automatic driving mode is to start the spring assembly 61 through the spring knob 62, thereby driving the eccentric wheel 63 to rotate, so that the tube core 2 moves axially forward and backward, and the rest of the working principle is consistent with the embodiment 1; the specific structure and working principle of the spring assembly 61 are prior art, and will not be elaborated in detail in the application; under the action of the spring 3, the tail end of the assembly part of the tube core 2 always abuts against the inner ring.

[0055] Example 3

[0056] See also Fig. 9 The automatic drive structure 7 replaces the operating handle and includes a housing (not shown in the figure). A motor 71 is arranged inside the housing. An eccentric wheel 72 is arranged on the output shaft of the motor 71. The outer ring of the eccentric wheel 72 is an arc groove structure. The tail end of the assembly part of the tube core 2 is against the outer ring. The motor is driven by a battery. The other structures of the automatic drive structure 7 are consistent with those of Example 1, and only the driving method is different. The automatic driving method is to drive the eccentric wheel 72 to rotate by the motor 71, so that the tube core 2 moves axially forward and backward. The rest of the working principle is consistent with that of Example 1. The battery can be a small button battery, or a large No. 5 or No. 7 battery. At the same time, a storage battery can also be used. The specific battery selection can be determined according to the actual situation. Under the action of the spring 3, the tail end of the assembly part of the tube core 2 always rests against the outer ring.
