Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a convenient clinical anesthesia stent structure. Background Technology

[0002] In clinical emergency care, patients sometimes need to undergo surgery and receive emergency anesthesia. However, in some special environments, the operating room is too small to accommodate the required anesthesia equipment, which makes the anesthesia procedure difficult. To facilitate the use of anesthesia equipment in clinical settings, a support structure is needed.

[0003] However, the traditional anesthesia stent structure usually achieves support through the expansion and contraction of tubular structures. However, due to the large number of tools required during clinical surgery, it is not convenient to provide directional support, making it inconvenient to use. In addition, during clinical surgery, it requires the connection of many infusion lines, which can easily cause pulling on the lines during the operation, thus affecting the normal use of the lines. Summary of the Invention

[0004] In view of this, the present invention provides a convenient clinical anesthesia stent structure, which has a bundle tube section and a branch support section. By opening a cylindrical groove on the top of the adjustment plate, it is easy to connect the connecting blocks, thereby facilitating the stability of the mating constraint blocks. By fixing the fixing frame to the adjustment plate, it is easy to fix the telescopic frame and the outer clamp, so that it can telescopically extend and rotate while maintaining stability, thereby increasing its support range and facilitating support in multiple directions during the operation. By fixing the outer frame to the external adjustment arm, the device can be adjusted in position while maintaining stability.

[0014] Beneficial effects

[0015] According to various embodiments of the present invention, the anesthesia stent structure, compared with the conventional stent structure, has a bundle tube section. By fixing the constraint plate to the external frame, it constrains the stabilizing frame while maintaining stability, making it easy to adjust. By opening a tube-clamping groove on the external frame, it is easy to constrain the infusion tube and thus easy to fix it. After the infusion tube is fixed, by rotating the bundle tube ring, it is easy to cover the tube-clamping groove, thereby preventing the infusion tube from being pulled and falling off during the operation, thus facilitating its normal use.

[0016] In addition, the adjustment section is located below the bundle tube section. By sliding the stabilizer to the constraint plate, it is easy to fix the connecting block under the action of the constraint plate, thereby preventing it from rotating. The adjustment rod is rotatably connected to the stabilizer, so that while rotating, the branch support and blocking section can be finely adjusted through the thread on the rod, thus facilitating its use. The constraint block is slidably connected inside the connecting block, so that it constrains the adjustment plate under the action of the return spring, thereby preventing it from rotating arbitrarily, making it easy to use during surgery.

[0017] In addition, the support section is located below the adjustment section. By rotating the adjustment plate to the bottom of the connecting block, the support section can be kept stable as a whole. By opening multiple sets of rectangular grooves on the adjustment plate, it is easy to fix the fixed frame, which in turn facilitates the installation of the telescopic frame and the outer card frame. This makes it easy to control the telescopic frame to extend and retract, and to control the outer card frame to flip, thereby increasing the overall support range of the device. This facilitates the support of external infusion tubes and surgical instruments, making it easy to use during surgery.

[0018] In addition, the blocking part is located above the branch support. By inserting the plug block into the outer clamp, it can be stabilized and other structures of the blocking part can be fixed. This facilitates the clamping of the infusion tube with the docking block. The expansion groove on the plug block facilitates the installation of the blocking block and the adjustment of the blocking block through the threaded hole. This facilitates the compression of the infusion tube, allowing for instantaneous blocking of the internal medication and preventing residual medication from being delivered to the patient when necessary.

The outer clamp 304 has a U-shaped structure, and the outer wall of the outer clamp 304 is provided with a cylindrical protrusion. The outer clamp 304 is provided with an arc-shaped structure, and the outer clamp 304 is rotatably connected to the telescopic frame 303.

[0041] like Figure 11 As shown, the blocking part 4 also includes: a contraction groove 402 and a connecting block 403; the contraction groove 402 is a rectangular groove, and the contraction groove 402 is connected to a threaded through hole, and the contraction groove 402 is located inside the insertion block 401; the contraction groove 402 is used to assist in the installation and fixation of the blocking block 404, so that it can be adjusted while maintaining stability, thereby facilitating its use; the connecting block 403 is a semi-circular ring structure, and the connecting block 403 is provided with a rectangular protrusion, and the connecting block 403 is fixed to the insertion block 401 by screws; the connecting block 403 is used to connect with the insertion block 401 by screws, thereby facilitating the restraint of the infusion tube, from To facilitate its use, the blocking part 4 also includes: a blocking block 404; the blocking block 404 is a rectangular block structure, the blocking block 404 has a semi-cylindrical protrusion, the blocking block 404 is rotatably connected to a threaded rod, the threaded rod of the blocking block 404 has a handle, the blocking block 404 is slidably connected in the contraction groove 402, and the threaded rod of the blocking block 404 is threadedly connected in the contraction groove 402; the blocking block 404 is used to adjust under the action of the threaded rod, thereby squeezing the infusion tube in the insertion block 401 and the docking block 403, so as to facilitate the blocking of the delivery of internal drugs and prevent residual drugs in the tube from being delivered to the patient's body.

[0042] The specific usage and function of this embodiment: In this invention, before use, the device needs to be manually moved to a designated location. Then, the device is fixed to the control arm via the external frame 101, making it easy to adjust the corresponding position of the device via the control arm. Then, the fixing frame 302 is fixed to the adjusting plate 301 with screws, facilitating the assembly of the telescopic frame 303 and the external clamping frame 304. During use, the infusion tubes and gas tubes required for surgical anesthesia are clamped in the clamping groove 103. By rotating the tubing ring 104, the clamping groove 103 is blocked during rotation, thus facilitating the restraint of the infusion tubes and gas tubes. To ensure stability, the telescopic frame 303 is pulled out of the fixed frame 302, exposing the outer clamp frame 304. The outer clamp frame 304 is then flipped over, increasing the support range of the device in conjunction with the telescopic frame 303. The insertion block 401 is then inserted into the outer clamp frame 304, and the infusion tube and gas tube are fixed in the semi-cylindrical groove of the insertion block 401 via the connecting block 403. During surgery, the infusion tube and gas tube are supported and restrained by the device, preventing them from being laid around the patient and avoiding accidental contact by medical staff during movement, thus facilitating use. The supporting part 3 provides support for the surgical instruments. The device provides support, facilitating surgical procedures. Multiple sets of fixing brackets 302 on the adjusting plate 301 allow for support in multiple directions. When a reverse conversion is needed, the adjusting plate 301 is directly moved, causing it to compress the constraint block 204 under pressure, retracting it into the connecting block 203. This releases the constraint on the adjusting plate 301, allowing for adjustment by rotation. The constraint block 204 then re-locks into the adjusting plate 301 under the action of a return spring, facilitating overall device operation. The entire device can be adjusted over a wide range using an external control arm. Simultaneously, by rotating the adjusting rod 202, the stabilizer 201 is lowered via the threaded control on the rod, which facilitates the adjustment of the branch support 3 and the blocking part 4, allowing for fine-tuning of the device and making it easy to use. During surgery, if it is necessary to stop the delivery of medication in an emergency, the threaded rod on the blocking block 404 can be rotated, which, while rotating, controls the blocking block 404 to adjust within the contraction groove 402 via the threaded control on the rod, thereby controlling the blocking block 404 to clamp the infusion tube or gas tube, delivering medication to the patient from the point of blockage, and then stopping the delivery equipment, thus facilitating control by medical staff and making it easy to use.
