Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a triple pressure measurement and fixation device for use in cardiac surgery anesthesia. Background Technology

[0002] During surgical anesthesia, monitoring arterial pressure, pulmonary artery pressure, and central venous pressure is crucial for assessing a patient's circulatory function and guiding anesthesia management. Continuous monitoring of arterial pressure allows for real-time monitoring of the patient's circulatory status, including cardiac function, peripheral vascular resistance, and organ perfusion, thus guiding the adjustment and use of anesthetic drugs. Monitoring pulmonary artery pressure provides timely information on changes in right ventricular function, offering important references for anesthesia management and enabling the implementation of other necessary treatment measures, such as the selection of vasoactive drugs and control of infusion rates, ensuring patient safety during the perioperative period. Monitoring central venous pressure indirectly assesses changes in volume and cardiac function, guiding the infusion rate and preventing over- or under-infusion, thereby ensuring stable circulatory function.

[0003] Patent CN220967305U discloses a device for storing wires, including an outer fixing post and an inner fixing post. The outer fixing post has a first mounting groove on its side, and the inner fixing post is located within the first mounting groove and rotatably connected to the outer fixing post. The inner fixing post has a second mounting groove on its side, and a first bolt is movably connected to the inner fixing post, passing through the second mounting groove. The space between the inner fixing post and the first bolt forms a first through hole for wire passing through. After a single wire is passed through the first through hole at any position, rotating the inner fixing post simultaneously winds or unwinds the wire portions on both sides of the storage device. The inner fixing post can be fixed at any position after rotation, allowing for adjustment of the wire length and easy disassembly.

[0004] However, the lead storage device has the following problems when used in anesthesia surgery to fix arterial pressure, pulmonary artery pressure, and central venous pressure leads: 1. The lead storage device can only fix and store one lead, and cannot fix arterial pressure, pulmonary artery pressure, and central venous pressure leads and prevent the three leads from getting tangled; 2. The lead storage device cannot be fixed to the anesthesia stent, nor can its height be adjusted on the anesthesia stent to accommodate different patients. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a triple pressure measurement and fixation device for cardiac surgery anesthesia, which at least solves the problems of existing device lead storage devices being unable to simultaneously fix three pressure measurement leads and being unable to be placed on an anesthesia stent.

[0006] The main idea of ​​the technical solution adopted in this utility model is as follows:

[0007] The design of a triple pressure monitoring and fixation device for cardiac surgery anesthesia includes: three sequentially connected outer shells, a fixing component connected to the middle outer shell, and a rotatable storage rod connected inside the outer shell. The three sequentially connected outer shells and their matching three storage rods can respectively fix the arterial pressure, pulmonary artery pressure, and central venous pressure leads, preventing the three leads from becoming entangled and affecting the surgical process. The spacing between the three outer shells can also be adjusted to allow for adjustment of the distance between the three leads according to the actual situation. The storage rod can retract or expand the leads when rotated, thereby adjusting the lead length. The fixing component can fix the entire device to an anesthesia stand for easy surgical execution.

[0008] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0009] Design a triple pressure measurement and fixation device for cardiac surgery anesthesia, comprising: three shells connected in sequence, each shell containing a storage component for storing fixed arterial pressure, pulmonary artery pressure and central venous pressure measuring leads; the spacing between adjacent shells is adjustable.

[0010] Furthermore, the storage assembly includes a storage rod rotatably connected within the housing; the storage rod is provided with a buckle for securing the pressure testing wire;

[0011] A limiting mechanism is provided between the storage rod and the outer shell.

[0012] Furthermore, a first threaded rod is provided on both sides of the middle outer shell, and a second threaded rod is provided on the opposite side of the outer shell on both sides; the first threaded rod and the adjacent second threaded rod are connected by an adjusting cylinder.

[0013] Furthermore, a through slot is provided in the middle of the outer casing to accommodate the pressure measuring wire; the storage rod passes through the through slot.

[0014] Furthermore, the bottom of the through groove is connected to a slot hole, and a rotating cylinder is rotatably installed inside the slot hole;

[0015] A spring is installed inside the rotating drum, and the top of the spring is connected to the storage rod.

[0016] Furthermore, the bottom of the storage rod is provided with two slots, and the top of the rotating cylinder is provided with a snap-fit ​​block that matches the two slots.

[0017] Furthermore, the limiting mechanism also includes limiting rods on both sides of the upper end of the storage rod, and multiple limiting grooves matching the limiting rods are provided at the top of the through groove.

[0018] Furthermore, a fastener is provided on the middle outer shell, which is used to fix the outer shell to the anesthesia frame.

[0019] The beneficial effects of this utility model are as follows: Compared with the prior art, the improvements of this utility model are:

[0020] 1. This utility model, by setting a first threaded rod, a second threaded rod, and an adjusting cylinder, enables the adjustment of the distance between adjacent outer shells by rotating the adjusting cylinder. This allows the spacing of the three wires to be changed according to surgical needs, avoiding the three wires from getting tangled together and preventing the wires from being too close to affect the surgical operation.

[0021] 2. This utility model, by setting up a storage rod and a rotating component, can fix the wire on the storage rod. At the same time, by rotating the storage rod through the rotating component, the wire can be wound and contracted or unwound on the storage rod. Medical staff can adjust the length of the wire according to the actual situation to avoid the wire being too long or too short, which would affect the surgical operation.

[0022] 3. By setting a fixing member connected to the middle outer shell, this utility model can not only fix the device to the anesthesia frame, but also fix the device to anesthesia frames of different diameters by screwing in bolts, and can also adjust the height of the fixing member according to the needs of the operation.

Therefore, they should not be construed as limitations on this utility model.

[0034] Example 1

[0035] like Figure 1 As shown, this application discloses a triple pressure measurement and fixation device for cardiac surgery anesthesia, including: three shells 10 connected in sequence, and further including: three shells 10 connected in sequence, each of the three shells 10 having a storage component for storing the fixed arterial pressure, pulmonary artery pressure and central venous pressure measuring leads. This not only fixes the three leads and prevents displacement, but also avoids problems caused by the three leads being entangled during the operation, thus affecting the surgical process; the spacing between adjacent shells 10 is adjustable, so that the spacing between the three leads can be adjusted according to the surgical situation to avoid the leads being too close and affecting the surgical operation.

[0036] Furthermore, the storage assembly includes a storage rod 20 rotatably connected to the housing 10, and the storage rod 20 is provided with a buckle 22 for fixing the pressure measuring wire; a limiting mechanism is provided between the storage rod 20 and the housing 10.

[0037] Furthermore, such as Figure 3 and Figure 4As shown, first threaded rods 30 are provided on both sides of the middle outer casing 10, a second threaded rod 31 is provided on the right end of the left outer casing 10, and a second threaded rod 31 is also provided on the left end of the right outer casing 10; the threads of the first threaded rods 30 and the second threaded rods 31 have opposite directions; as shown... Figure 1 As shown, adjusting cylinders 50 are provided on the second threaded rod 31 on the left outer shell 10 and the corresponding first threaded rod 30 on the middle outer shell 10. The adjusting cylinders 50 are provided with threaded sections that match the first threaded rod 30 and the second threaded rod 31. Adjusting cylinders 50 are also provided on the second threaded rod 31 on the right outer shell 10 and the corresponding first threaded rod 30 on the middle outer shell 10. The adjusting cylinders 50 are provided with threaded sections that match the first threaded rod 30 and the second threaded rod 31. By rotating the adjusting cylinders 50 clockwise or counterclockwise, the distance between two adjacent outer shells 10 can be adjusted, thereby adjusting the distance between the three wires according to the surgical situation to avoid the wires being too close and affecting the surgical operation.

[0038] Furthermore, such as Figure 3 As shown, a through groove 11 is provided in the middle of the outer casing 10; the top and bottom of the through groove 11 are respectively provided with a first through hole 12 and a slot 13 that match the storage rod 20. The first through hole 12 and the slot 13 are used to insert the storage rod 20. When it is necessary to retract the wire, rotating the storage rod 20 can make the wire wrap around the storage rod 20. The through groove 11 is provided to prevent the wire from not having enough space to wrap around the outer diameter of the storage rod 20 when retracting the wire. It also prevents the buckle 22 from being blocked by the outer casing 10 when the storage rod 20 rotates, which would prevent the storage rod 20 from rotating.

[0039] Furthermore, such as Figure 6 As shown, a rotating cylinder 60 and a spring 61 are provided in the slot 13; the rotating cylinder 60 is rotatably connected to the slot 13 through a bearing; the spring 61 is provided in the rotating cylinder 60, and its two ends are respectively connected to the rotating cylinder 60 and the storage rod 20.

[0040] Furthermore, such as Figure 5 As shown, the storage rod 20 has two slots 24 at its bottom, and the rotating cylinder 60 has a snap-fit ​​block 62 at its top that matches the two slots 24. The storage rod 20 has an adjustment post 21 at its top that is larger than the diameter of the first through hole 12. After pressing the adjustment post 21, the two slots 24 at the bottom of the storage rod 20 engage with the two snap-fit ​​blocks 62 at the top of the rotating cylinder 60, so that the storage rod 20, the rotating cylinder 60 at its bottom, and the spring 61 rotate simultaneously after the adjustment post 21 is rotated.

[0041] Furthermore, such as Figure 7As shown, limit rods 23 are provided on both sides of the upper end of the storage rod 20, and multiple limiting grooves 14 matching the limit rods 23 are provided at the top of the through groove 11. When the spring 61 is in the normal state, the spring 61 pushes the storage rod 20 up, and the limit rods 23 on the storage rod 20 cooperate with the limiting grooves 14. At this time, the storage rod 20 is locked and cannot be rotated. When it is necessary to store the wire, press the adjusting column 21. At this time, the limit rods 23 on the storage rod 20 move downward and disengage from the limiting grooves 14. At the same time, the spring 61 is compressed, and the two grooves at the bottom of the storage rod 20 open. The opening 24 engages with the two locking blocks 62 at the top of the rotating drum 60. When the adjusting column 21 is pressed, it rotates, causing the storage rod 20, the rotating drum 60, and the spring 61 at its bottom to rotate together, thereby allowing the wire to be wound around the storage rod 20 and enabling the wire to retract and unwind. When the wire retracts to the appropriate length, the adjusting column 21 is released, and the spring 61 returns to its normal state, lifting the storage rod 20. The limiting rod 23 on the storage rod 20 moves upward and engages with the corresponding limiting groove 14, thereby locking the storage rod 20.

[0042] Example 2

[0043] Based on Example 1, in order to fix the triple pressure monitoring and fixation device used for cardiac surgery anesthesia onto the anesthesia stent, further, as shown in Example 1... Figure 2 As shown, a fastener 40 is provided on the outer shell 10 located in the middle. A second through hole 41 is provided on the top of the fastener 40. The fastener 40 is sleeved on the anesthesia support through the second through hole 41, thereby realizing the overall fixation of the device on the anesthesia support.

[0044] Furthermore, the fixation member 40 has a threaded hole 42 on its side end, and is equipped with a bolt that matches the threaded hole 42. By screwing in the bolt, the fixation member 40 can be fixed to anesthesia supports of different diameters, and the height of the fixation member 40 can also be adjusted according to the needs of the surgery.

[0045] The specific operation of the triple pressure monitoring and fixation device for cardiac surgery anesthesia provided in this utility model is as follows:

[0046] The fixing piece 40 is fitted onto the anesthesia support. After adjusting it to a suitable height, a bolt is screwed into the threaded hole 42 to fix the fixing piece 40 and the device onto the anesthesia support. Then, the arterial pressure, pulmonary artery pressure, and central venous pressure leads are respectively secured to the three clips 22. When it is necessary to retract or release the leads, press the adjusting column 21. At this time, the limiting rod 23 on the retraction rod 20 moves downward and disengages from the limiting groove 14. At the same time, the spring 61 is compressed, and the two slots 24 at the bottom of the retraction rod 20 and the top of the rotating cylinder 60 are connected. The two locking blocks 62 engage. When the adjusting column 21 is pressed, it rotates, causing the storage rod 20, the rotating drum 60, and the spring 61 at its bottom to rotate together, thereby allowing the wire to be wound around the storage rod 20 and enabling the wire to retract and unwind. When the wire retracts to the appropriate length, the adjusting column 21 is released, and the spring 61 returns to its normal state, lifting the storage rod 20. The limiting rod 23 on the storage rod 20 moves upward and engages with the corresponding limiting groove 14, thereby locking the storage rod 20.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
