Description

Technical Field

[0001] This utility model relates to the field of medical drainage tube technology, and more specifically, to a visual hematoma crushing and aspiration drainage tube. Background Technology

[0002] Intracranial hematoma is a common critical condition in neurosurgery, often caused by trauma, cerebrovascular disease, etc. At present, surgical treatment is often a necessary choice for patients with large bleeding volume, obvious mass effect, or progressive worsening of condition.

[0003] In clinical practice, when using thin drainage tubes with good compliance, they are very easy to become blocked, thus failing to achieve the therapeutic purpose. On the other hand, when using drainage tubes with large diameters, due to the poor compliance of the drainage tube ends, it is generally necessary to insert two drainage tubes into the patient's head, one for injecting irrigation solution and the other for drainage. This not only increases surgical trauma and risks, but also makes the operation cumbersome and prolongs the operation time.

[0004] A search revealed that Chinese patent CN107174681A discloses a drainage tube. This structure involves inserting the drainage tube into the cranium along a channel. During insertion, the head of the drainage tube first enters the channel. Due to the pressure from the lateral walls of the brain tissue, the strip-shaped portions converge into a conical shape. The head of the drainage tube advances along the channel until it enters the hematoma cavity. After entering the hematoma cavity, the lateral walls of the brain tissue disappear, and the strip-shaped portions of the head of the drainage tube become dispersed. The working fluid enters the hematoma cavity through the flushing chamber, mixes with the cerebral hemorrhage, and then flows out through the effusion gaps into the drainage cavity, completing the entire cleaning process. This increases the drainage fluid's flow area and improves drainage efficiency. When the drainage tube is removed, the above process reverses.

[0005] However, in actual use, after inserting the drainage tube into the cranium through this channel, the craniotomy hematoma is directly removed. It is difficult to effectively deal with larger hematomas or blood clots, resulting in incomplete drainage and easy blockage. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a visual hematoma fragmentation aspiration and drainage tube to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0014] By adopting the above technical solution, the pulverized hematoma can be easily aspirated and drained, and drugs can also be injected internally, thereby improving the effectiveness of the treatment.

[0015] The technical effects and advantages of this utility model are as follows:

[0017] 2. By setting up a drainage mechanism, compared with existing technologies, a matching medical syringe is connected to a sealed tube connector. Then, the branch tube is opened and the fixed tube is closed. The syringe is pulled outward to drive the hematoma or blood clot inside the patient's hematoma cavity into the drainage cavity inside the drainage tube body through the inlet. The drainage cavity enters the interior of the connecting tube through the drainage tube, and then is delivered to the delivery tube through the branch tube. Finally, it is delivered to the syringe through the sealed tube connector, thereby aspirating the hematoma or blood clot inside the patient's hematoma cavity. It can also be used to inject drugs, and has good biocompatibility and safety, without causing damage to intracranial tissues. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The embodiments disclosed in this application are as follows: Figure 1-5The illustrated visual hematoma crushing and aspiration drainage tube includes a drainage tube body 1, with two liquid inlets 2 on the surface of the drainage tube body 1, a connecting hose 3 fixedly installed on one side of the drainage tube body 1, and a crushing mechanism fixedly installed on one side of the connecting hose 3.

[0026] The pulverizing mechanism includes a fixed hose 4 fixedly mounted on one side of the connecting hose 3. A sleeve connector 5 is fixedly mounted on one side of the fixed hose 4. A pulverizing rod 6 is slidably connected inside the sleeve connector 5. A threaded pulverizing rod 7 is fixedly mounted on one end of the pulverizing rod 6, and a handle 8 is fixedly mounted on the other end of the pulverizing rod 6. One end of the pulverizing rod 6 passes through the connecting hose 3 and the drainage tube body 1 in sequence and extends into the drainage tube body 1. The pulverizing rod 6 and one end of the threaded pulverizing rod 7 are aligned with the sleeve connector 5. Then, the sleeve connector 5 and the threaded pulverizing rod 7 are inserted into the sleeve connector 5, the connecting hose 3, and the drainage tube body 1 in sequence until the threaded pulverizing rod 7 contacts the bottom of the drainage tube body 1. By rotating the handle 8, the medical staff can drive the pulverizing rod 6 to rotate in the forward direction, thereby causing the pulverizing rod 6 to drive the threaded pulverizing rod 7 to rotate, breaking up the hematoma or blood clot. This also makes the hematoma visible, allowing doctors to more accurately determine the location, size, and shape of the hematoma, thus improving the effectiveness of the treatment.

[0027] Reference Figure 2-3 As shown, a main flow-stop sleeve 9 is fitted over the fixed tubing 4. The surface of the main flow-stop sleeve 9 has multiple slots 10. A connector 11 is engaged inside the slots 10. One end of the connector 11 is connected to the main flow-stop sleeve 9. A branch tubing 12 is fitted over a branch flow-stop sleeve 16. The surface of the branch flow-stop sleeve 16 has multiple fixing grooves 17. A fixing head 18 is engaged inside the fixing grooves 17. One end of the fixing head 18 is connected to the branch tubing 12. Then, pull the sealing cap 15 outward to open the sealing tube connector 14. Next, connect the matching medical syringe to the sealing tube connector 14. Then, open the branch tubing 12, thereby pressing the branch flow-stop sleeve 16 to move the fixing head 18, thus separating it from the fixing groove 17. Then, close the fixed tubing 4, thereby pressing the main flow-stop sleeve 9 to move the connector 11, thus engaging it with the slot 10 in the appropriate position. The preparation of the drainage tube body 1 is completed.

[0028] Reference Figure 4-5As shown, a drainage mechanism is fixedly installed on one side of the connecting hose 3. The drainage mechanism includes a branch hose 12 fixedly installed on one side of the connecting hose 3. A delivery hose 13 is fixedly installed at one end of the branch hose 12. A sealing connector 14 is fixedly installed at one end of the delivery hose 13. A sealing cap 15 is snapped into the inside of the sealing connector 14. A drainage cavity 19 is opened inside the drainage tube body 1. The drainage tube body 1, the connecting hose 3, the fixed hose 4, and the branch hose 12 are all made of transparent medical-grade silicone. When the medical staff rotates the handle 8, the crushing rod 6 rotates in the forward direction, thereby causing the crushing rod 6 to drive the threaded crushing rod 7 to rotate. At the same time, the syringe pulls outward, causing the hematoma or blood clot inside the patient's hematoma cavity to enter the drainage cavity 19 inside the drainage tube body 1 through the inlet 2. The hematoma or blood clot is broken up by the rotation of the threaded crushing rod 7, making it easy to enter the connecting tube 3 through the drainage cavity 19. Then it is delivered to the delivery tube 13 through the branch tube 12, and then to the syringe through the sealing tube connector 14, so as to aspirate the hematoma or blood clot inside the patient's hematoma cavity. After use, the handle 8 is pulled outward to remove the crushing rod 6 and the threaded crushing rod 7. Since the drainage tube body 1, the connecting tube 3, the fixing tube 4 and the branch tube 12 are all made of transparent medical-grade silicone, it is not only easy to observe the crushing of the blood clot, but also allows doctors to more accurately judge the location, size and shape of the hematoma. The drainage tube body 1 is soft inside the patient's hematoma cavity, with good biocompatibility and safety, and will not cause damage to intracranial tissue.

[0029] Working principle of this utility model:

[0030] This utility model is a visual hematoma crushing and aspiration drainage tube. When using this device, before inserting the drainage tube body 1, first align one end of the crushing rod 6 and the threaded crushing rod 7 with the sleeve connector 5. Then, insert the sleeve connector 5 and the threaded crushing rod 7 into the sleeve connector 5, the connecting hose 3 and the drainage tube body 1 in sequence until the threaded crushing rod 7 contacts the bottom of the drainage tube body 1. Then, pull the sealing cap 15 outward to open the sealing tube connector 14. Next, connect the matching medical syringe to the sealing tube connector 14. Then, open the branch hose 12, thereby pressing the branch stop sleeve 16 to drive the fixing head 18 to move, thereby separating it from the fixing groove 17. Then, close the fixing hose 4, thereby pressing the main stop sleeve 9 to drive the snap connector 11 to move, thereby snapping it into the snap groove 10 in the appropriate position. The preparation of the drainage tube body 1 is completed. The main stop sleeve 9 and the branch stop sleeve 16 can be adjusted according to the size of the hematoma and the drainage requirements to ensure smooth drainage.

[0031] Then, using existing clinical instruments, a pre-punctured channel is created within the cranium to connect to the patient's hematoma cavity. The drainage tube body 1 is then inserted into the cranium along this channel. Once it reaches the patient's hematoma cavity, the medical staff rotates the handle 8, causing the pulverizing rod 6 to rotate forward. This, in turn, causes the threaded pulverizing rod 7 to rotate. Simultaneously, the syringe pulls the hematoma or blood clot inside the patient's hematoma cavity outward, drawing it through the inlet 2 into the drainage cavity 19 inside the drainage tube body 1. The rotation of the threaded pulverizing rod 7 further breaks up the hematoma or blood clot, facilitating its entry into the connecting tubing 3 through the drainage cavity 19. The hematoma or blood clot inside the patient's hematoma cavity is then aspirated through the branch tube 12 to the delivery tube 13, and then through the sealed tube connector 14 to the syringe. After use, the handle 8 is pulled outward to remove the pulverizing rod 6 and the threaded pulverizing rod 7. Since the drainage tube body 1, the connecting tube 3, the fixing tube 4 and the branch tube 12 are all made of transparent medical-grade silicone, it is not only convenient to observe the pulverization of the blood clot, but also allows doctors to more accurately judge the location, size and shape of the hematoma. The drainage tube body 1 is soft inside the patient's hematoma cavity, with good biocompatibility and safety, and will not cause damage to intracranial tissue.

[0032] When medication is needed, first press the shunt sleeve 16 to move the fixing head 18, thereby locking the fixing head 18 into the appropriate fixing groove 17. Then close the shunt tube 12, remove the syringe, install the medication syringe, and then repeat the above steps in reverse order to open the shunt tube 12. Next, inject the medication into the drainage tube body 1 through the sealing tube connector 14, the shunt tube 12, and the connecting tube 3, and then inject it into the hematoma cavity through the inlet 2, thereby achieving drug treatment. The operation is convenient and quick. After use, slowly pull out the drainage tube body 1 and clean and disinfect the drainage tube body 1 in time for the next use.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
