Description

Technical Field

[0001] This utility model belongs to the technical field of cerebral hematoma drainage devices, specifically relating to an assemblable cerebral hematoma drainage device. Background Technology

[0002] Cerebral hematoma refers to a hematoma within the brain parenchyma. When treating patients with cerebral hematoma, it is necessary to drain and eliminate the hematoma. Usually, a drainage device is used to drain and eliminate the cerebral hematoma. The existing drainage device is the equipment used for draining and eliminating cerebral hematoma. When in use, the drainage device is easy to limit and fix to the patient's head, and is positioned and reinforced inside the patient's brain. After fixing and installing, it is easy to quickly assemble the drainage device for drainage, making drainage convenient.

[0003] Existing drainage devices for treating cerebral hematoma involve drilling a hole in the brain using a limiting plate and then guiding the drainage tube into the brain via a guide wire. This means that with the drainage tube positioned externally to the brain, it's difficult to position the tube end inside the brain. This results in instability and movement of the drainage tube during drainage or when the patient is not in use and experiences external forces, potentially causing it to dislodge and cause significant pain. This compromises the stability of the drainage device when used for hematoma drainage in patients with cerebral hematoma. Therefore, this invention proposes an assemblable drainage device for cerebral hematoma. Utility Model Content

[0004] The purpose of this invention is to provide an assemblable drainage device for cerebral hematoma, in order to solve the problem mentioned in the background art that when the drainage device is used for the treatment and drainage of cerebral hematoma, it is not convenient to position and install the end of the drainage tube inside the brain. This causes the drainage tube to shake and become unstable when the patient is under external force during drainage or when it is not in use and is placed on the brain. In severe cases, it may even fall off and cause obvious pain to the patient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assemblable drainage device for cerebral hematoma, comprising an assemblable drainage device body, the assemblable drainage device body including a brain limiting plate, a limiting hole formed inside the brain limiting plate, a flexible drainage tube penetrating through the limiting hole, an inlet wire disposed inside the flexible drainage tube, an assembly clamping head disposed at the end of the flexible drainage tube, a protective pad disposed on one side of the assembly clamping head, and the assemblable drainage device body further comprising:

[0006] The positioning and fixing mechanism includes a positioning and fixing component disposed at the top of the flexible drainage tube body. The inner surface of the positioning and fixing component is provided with a snap-fit ​​installation component, and the inner surface of the positioning and fixing component is provided with an inflation component located inside the flexible drainage tube body.

[0007] A branched multi-position drainage mechanism, wherein the branched multi-position drainage mechanism includes a branched multi-position drainage component disposed at the top of a flexible drainage tube, and an installation component is disposed at the connection between the bottom end of the branched multi-position drainage component and the flexible drainage tube.

[0008] Preferably, the positioning and reinforcement component includes an inner connecting ring disposed at the top of the flexible drainage tube body, the outer surface of the inner connecting ring is integrally formed with an expansion positioning body, and an inflation cavity is formed at the connection between the inner surface of the expansion positioning body and the surface of the inner connecting ring.

[0009] Preferably, the locking and mounting assembly includes locking balls integrally formed at both ends of the inner surface of the inner connecting ring, and locking holes are opened at the top edge of the flexible drainage tube, and the locking balls are locked and connected to the inside of the locking holes.

[0010] Preferably, the inflation assembly includes an installation groove formed inside one side of the flexible drainage tube body, an inflation connecting pipe is provided inside the installation groove, the bottom end of the inflation connecting pipe is provided with an external threaded inlet on the bottom side of the flexible drainage tube body, a connection port is provided inside the inflation chamber, and the top end of the inflation connecting pipe is sealed and engaged with the inside of the connection port.

[0011] Preferably, the outer surface of the external thread inlet is threaded with an internal thread fixing cap, and the inner surface of the internal thread fixing cap is sealed and engaged with the interior of the external thread inlet.

[0012] Preferably, the branched multi-position drainage assembly includes two branch drainage tubes disposed at the top end of the flexible drainage tube body, and the two branch drainage tubes are symmetrically arranged.

[0013] Preferably, the installation assembly includes two internally threaded holes at the top of the flexible drainage tube body, and the end of the branch drainage tube is provided with an externally threaded head, with a limit ring integrally formed at the edge of the externally threaded head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a fixed positioning mechanism, the expansion positioning body can be fitted onto the outer surface of the flexible drainage tube and fixed before the main body of the assembled drainage device is used to drain the hematoma in the patient's brain. When the flexible drainage tube extends to the hematoma location inside the brain, the expansion positioning body follows into the interior, and the air chamber is filled with air to inflate the expansion positioning body. When the expansion positioning body inflates, it presses tightly against the installation position inside the brain for positioning and reinforcement. After the flexible drainage tube is reinforced and installed, it is easier to drain the hematoma more stably. At the same time, after use, it is easier to place it more stably when the patient moves normally, and it is not easy to loosen or fall off. This improves the stability of the positioning and installation of the main body of the assembled drainage device when using it to drain the hematoma in patients with brain hematoma.

Detailed Implementation

[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] Please see Figures 1 to 7This utility model provides a technical solution: an assemblable drainage device for cerebral hematoma, including an assemblable drainage device body 100. The assemblable drainage device body 100 includes a brain limiting plate 101, with a limiting hole 102 formed inside the brain limiting plate 101. A flexible drainage tube 103 passes through the limiting hole 102, and an inlet wire 104 is provided inside the flexible drainage tube 103. An assembly clip 105 is provided at the end of the flexible drainage tube 103. The brain limiting plate 101 is closed and fixed at the location in the patient's brain where drainage is needed. Medical personnel make a hole in the limiting hole 102 corresponding to the patient's head. The flexible drainage tube 103 passes through the limiting hole 102 and extends into the brain to contact the hematoma. After installation, it is quickly assembled with an external drainage device via the assembly clip 105. When the drainage device creates negative pressure inside the flexible drainage tube 103, it aspirates the hematoma. A protective pad 106 is provided on one side of the assembly clip 105. The hematoma in the brain needs to be drained multiple times. After one drainage is completed, the end of the flexible drainage tube 103 is quickly detached via the assembly clip 105, and the protective pad 106 is locked inside the assembly clip 105 for protection. The main body 100 of the assembled drainage device is also provided with:

[0026] The system includes a positioning and reinforcement mechanism, which includes a positioning and reinforcement component located at the top of the flexible drainage tube 103. The inner surface of the positioning and reinforcement component is provided with a snap-fit ​​installation component, and the inner surface of the positioning and reinforcement component is provided with an inflation component located inside the flexible drainage tube 103. When the assembled drainage device body 100 is used to drain the hematoma in a patient with cerebral hematoma, the positioning and reinforcement mechanism positions and reinforces the end of the flexible drainage tube 103 inside the brain, which facilitates more stable drainage of the hematoma. At the same time, after use, it is easier to place it more stably when the patient moves normally, and it is not easy to loosen or fall off, thereby improving the stability of the positioning and installation of the assembled drainage device body 100 when used to drain the hematoma in a patient with cerebral hematoma.

[0027] To facilitate the positioning and reinforcement of the flexible drainage tube 103 after it is embedded into the brain, in this embodiment, preferably, the positioning and reinforcement component includes an inner connecting ring 1033 disposed at the top of the flexible drainage tube 103. An expansion positioning body 1031 is integrally formed on the outer surface of the inner connecting ring 1033. An inflation cavity 1032 is formed at the connection between the inner surface of the expansion positioning body 1031 and the surface of the inner connecting ring 1033. This allows the expansion positioning body 1031 and the inflation cavity 1032 to be inflated and positioned for reinforcement after the flexible drainage tube 103 extends into the brain.

[0028] To facilitate the secure installation of the inner connecting ring 1033 and the expansion positioning body 1031 on the outer surface of the flexible drainage tube body 103 using a snap-fit ​​installation assembly, in this embodiment, preferably, the snap-fit ​​installation assembly includes snap-fit ​​balls 1037 integrally formed at both ends of the inner surface of the inner connecting ring 1033, and snap-fit ​​holes 1038 are opened at the top edge of the flexible drainage tube body 103. The snap-fit ​​balls 1037 are snap-fitted into the interior of the snap-fit ​​holes 1038. After the expansion positioning body 1031 and the inner connecting ring 1033 are fitted and installed on the top outer surface of the flexible drainage tube body 103, the snap-fit ​​balls 1037 are snapped into the interior of the snap-fit ​​holes 1038 for secure installation.

[0029] To facilitate the inflation of the inflation chamber 1032 and the positioning and reinforcement of the flexible drainage tube 103 using the inflation assembly, in this embodiment, preferably, the inflation assembly includes an installation groove 1034 formed on one side inside the flexible drainage tube 103. An inflation connecting pipe 1036 is disposed inside the installation groove 1034. The bottom end of the inflation connecting pipe 1036, located on the bottom side of the flexible drainage tube 103, has an external threaded inlet 1039. A connection port 1035 is formed on the inner side of the inflation chamber 1032, and the top end of the inflation connecting pipe 1036 is sealed and engaged with the inside of the connection port 1035, facilitating the inflation... After the outer surface of the positioning body 1031 is embedded into the brain along with the flexible drainage tube 103, the external threaded inlet 1039 is connected to the inflator and fills the inflation chamber 1032 with air through the inflation connecting pipe 1036 for positioning and installation. This allows the flexible drainage tube 103 to be positioned and reinforced. The outer surface of the external threaded inlet 1039 has an internal threaded fixing cap 1030 that rotates around the thread. The inner surface of the internal threaded fixing cap 1030 is sealed and engaged with the inside of the external threaded inlet 1039. After inflation, the internal threaded fixing cap 1030 is rotated to seal and fix the external threaded inlet 1039, which facilitates the storage of gas and reinforces its placement.

[0030] The multi-position drainage mechanism includes a multi-position drainage component disposed at the top of the flexible drainage tube 103. An installation component is provided at the connection between the bottom end of the multi-position drainage component and the flexible drainage tube 103. When the assembled drainage device body 100 is used for cerebral hematoma drainage, the flexible drainage tube 103 facilitates the multi-position drainage mechanism to drain the hematoma at multiple locations inside the brain. The multi-position drainage is convenient and fast, improving the drainage rate and convenience of the assembled drainage device body 100 when used for hematoma drainage.

[0031] In order to facilitate the drainage of hematomas in multiple locations in the brain using the branched multi-location drainage component, in this embodiment, preferably, the branched multi-location drainage component includes two branched drainage tubes 107 disposed at the top end of the flexible drainage tube body 103. The two branched drainage tubes 107 are symmetrically arranged, so that when the end of the flexible drainage tube body 103 is embedded into the brain, the branched drainage tubes 107 are also embedded into the brain along with the flexible drainage tube body 103, which facilitates the drainage of hematomas in multiple locations within the brain, and the drainage is faster and more convenient.

[0032] To facilitate the rapid rotation and fixation of the branch drainage tube 107 using the installation assembly, in this embodiment, preferably, the installation assembly includes two internal threaded holes 1072 opened at the top of the flexible drainage tube body 103, and an external threaded head 1071 is provided at the end of the branch drainage tube 107. A limiting ring 1073 is integrally formed at the edge of the external threaded head 1071, which facilitates the fixing and installation of the branch drainage tube 107 by rotating the external threaded head 1071 inside the internal threaded holes 1072, and is fixed by the limiting ring 1073 during rotation.

[0033] The working principle and usage process of this utility model: Before use, the brain limiting plate 101 is closed and fixed at the position in the patient's brain where drainage is needed. Medical personnel make a hole in the limiting hole 102 corresponding to the patient's head. After opening, the flexible drainage tube 103 is inserted through the limiting hole 102 by the steel wire 104 until it extends into the brain and contacts the hematoma. After installation, the steel wire 104 is pulled out. The assembly head 105 is used to quickly assemble it with the external drainage device. When the drainage device generates negative pressure inside the flexible drainage tube 103, it sucks up the hematoma generated inside. Therefore, the hematoma in the brain needs to be drained multiple times. After one drainage is completed, the end of the flexible drainage tube 103 is quickly disassembled by the assembly head 105, and the protective pad 106 is locked inside the assembly head 105 for protection.

[0034] Before the assembled drainage device body 100 is used to drain the hematoma in the patient's brain, the inner connecting ring 1033 is fitted onto the outer surface of the flexible drainage tube body 103. The expansion positioning body 1031 is then installed by locking the ball 1037 inside the locking hole 1038. After installation, the expansion positioning body 1031 follows the flexible drainage tube body 103 as it extends to the hematoma site inside the brain. The end of the external thread inlet 1039 is then engaged with the external inflator to inflate the air inlet connecting tube 1036 until the air chamber 1032 is filled with air and the expansion positioning body 1031 bulges. The inflator is then removed, and the internal thread is rotated to fix it. The cover 1030 is locked onto the surface of the external thread inlet 1039 for sealing and fixation. When the expansion positioning body 1031 bulges, it presses tightly against the position where it is installed inside the brain, and the end of the flexible drainage tube 103 is positioned and reinforced inside the brain. During the positioning and installation, the expansion positioning body 1031 bulges to a certain degree and is made of soft material, which is not likely to cause pain to the patient. Therefore, after the flexible drainage tube 103 is reinforced and installed, it is easier to drain the hematoma more stably. At the same time, after use, it is easier to place it more stably when the patient moves normally, and it is not easy to loosen or fall off. This improves the stability of the positioning and installation of the assembled drainage device body 100 when the patient with cerebral hematoma uses it for hematoma drainage.

[0035] Finally, before using the assembled drainage device body 100, rotate the external threaded head 1071 in the internal thread of the internal threaded hole 1072 to rotate and fix the branch drainage tube 107 until the inner surface of the limiting ring 1073 contacts the surface of the flexible drainage tube body 103 and stops rotating. The branch drainage tube 107 is then fixedly installed. When the assembled drainage device body 100 extends the flexible drainage tube body 103 to the brain, the branch drainage tube 107 is extended to the hematoma inside the patient's brain through the flexible drainage tube body 103. This facilitates simultaneous drainage treatment at multiple locations inside the patient's brain without the need for multiple drilling for drainage. The drainage is faster and more convenient, improving the drainage rate and convenience of the assembled drainage device body 100 when used for hematoma drainage.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
