Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a subclavian deep vein compression hemostat. Background Art

[0002] In clinical practice, removal of deep venous catheters (such as subclavian vein catheters) is a routine procedure. However, due to its large diameter, high intraluminal pressure, and deep location (behind the clavicle and above the first rib), the subclavian vein leaves a significant puncture channel in the vessel wall after removal. In the absence of external pressure, blood can easily continue to overflow from this channel due to venous pressure. To effectively stop bleeding, prevent local hematoma formation, and even more serious complications (such as increased risk of hemothorax), continuous, stable, and sufficient pressure must be applied to the puncture channel in the vessel wall.

[0003] Currently, clinical practice generally relies on direct manual pressure from healthcare professionals. The operator must precisely place the base of their fingers or palms on the corresponding area of ​​the supraclavicular fossa, applying sufficient pressure and maintaining it for typically 15 to 30 minutes, or even longer (especially for patients with coagulation disorders or those taking anticoagulants), to ensure closure of the vascular rupture, thrombosis, and initial scab formation. This procedure has significant drawbacks: First, it demands the full attention and physical strength of a qualified healthcare professional, preventing them from performing any other diagnostic, treatment, or nursing tasks during this time. Furthermore, prolonged, precise pressure places a severe strain on the operator's stamina and concentration, and fatigue can easily lead to uneven or displaced pressure, compromising hemostasis effectiveness. Furthermore, in the context of generally limited medical resources and saturated workloads among healthcare professionals, this inefficient and entirely manual method of hemostasis significantly limits the operational efficiency of healthcare units, exacerbating the imbalance between supply and demand for human resources and hindering the optimization of healthcare service processes while ensuring patient safety. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a subclavian deep vein compression hemostat, which can perform stable equalization of pressure on the puncture point for a long time, freeing the hands of medical staff.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame.

[0008] In at least one embodiment, a through hole may be provided on the upper surface of the end of the square rod away from the mounting seat and passing through the lower surface, and the pressure rod may be movably arranged in the through hole; a fastening bolt for fastening the relative position of the pressure rod in the through hole is provided on the outer side surface of the through hole.

[0009] In at least one embodiment, a T-shaped pressing block is hinged to the lower end of the pressing rod, and the lower end of the pressing rod and the T-shaped pressing block are detachably connected via bolts and nuts.

[0011] In at least one embodiment, the lifting device adopts an electric push rod; the mounting base is provided with an internal cavity, a controller and a battery are provided inside, and a control button is provided on the outer surface; the electric push rod is fixed to the upper surface of the thrust ball bearing, and the telescopic end of the electric push rod abuts against the lower surface of the lever; the controller receives instructions through the control button and drives the electric push rod to rotate forward and reverse, so as to drive the lifting and lowering of the telescopic end of the electric push rod, and then drives the lever to realize the tightening and loosening of the pressure rod; the battery is used to provide working voltage.

[0012] In at least one embodiment, waist-shaped plates are provided on both side edges of the bottom of the square sleeve, and the waist-shaped plates are located directly above the electric push rod.

[0014] Compared with the existing technology, the present invention achieves at least the following beneficial effects: the present invention realizes mechanized continuous downward force output through the mechanical structure of the lever-linked pressure rod driven by the lifting device. Medical staff only need to initially position and adjust the lifting device to automatically maintain the compression state, completely freeing the hands of medical staff so that they can perform other medical tasks simultaneously, significantly improving the efficiency of human resource utilization.

[0021] like Figures 1 to 2 As shown, the subclavian deep vein compression hemostat of the present invention includes a mounting base 1, a support arm 2, a lever 3, a pressure rod 4, and a lifting device 5. A square base plate 110 is provided at the bottom of the mounting base 1, and the mounting base 1 is fixedly connected to the upper surface of one end of the square base plate 110. The support arm 2 is arranged upwardly and tilted, and a rotating cylinder 21 with an axis vertically downward is fixedly connected to its lower end. A rotating shaft 120 is vertically provided on the upper surface of the mounting base 1, and the support arm 2 is rotatably mounted on the rotating shaft 120 via the rotating cylinder 21. The lever 3 is provided at the top end of the support arm 2, and hinge shafts 310 are symmetrically provided on both sides of the middle area of ​​the lever 3. The upper end of the support arm 2 is provided with a hinge seat 22, and support ears 221 are vertically provided on both sides of the hinge seat 22. The lever 3 is rotatably hinged between the support ears 221 on both sides of the hinge seat 22 via the hinge shaft 310. The pressure rod 4 is vertically provided at the end of the lever 3 away from the mounting base 1. The lifting device 5 is arranged between the upper surface of the rotating shaft 120 and the lower surface of the lever 3, and has a telescopic end that can be lifted and lowered. The bottom of the lifting device 5 contacts the upper surface of the rotating shaft 120, and the telescopic end abuts the lower surface of the lever 3.

[0022] The square base plate 110 of this embodiment not only maintains the stability of the mounting base 1, but also provides a compressive or clamping force for the lifting device 5 to drive the lever 3 and the pressure rod 4 to achieve continuous downward force output. The top end of the support arm 2 serves as a support point for the lever 3. The support arm 2 is rotatably mounted on the shaft 120 via a rotating cylinder 21. This arrangement facilitates angle adjustment for different puncture points, eliminating the need to swing the square base plate 110 for angle adjustment. Furthermore, when the square base plate 110, the mounting plate, the support arm 2 and the lever 3 are connected to each other, a U-shaped structure with an opening on the side is formed. When in use, the U-shaped structure is inserted flat on the patient's lying body, wherein the base plate is located between the patient's back and the bed board when the patient is lying flat. When the telescopic end of the lifting device 5 lifts one end of the lever 3, the lever 3 provided with a pressure rod 4 will drive the pressure rod 4 to press down. The lower end of the pressure rod 4 is used to align with the patient's puncture point. After the pressure rod 4 is pressed down, its lower end will compress the puncture point to stop bleeding, replacing the existing manual pressing method. At the same time, since the pressing force is provided by the lifting device 5, the medical staff only needs to initially position and adjust the lifting device 5 to automatically maintain the pressing state, effectively avoiding the force fluctuation and position deviation of manual pressing, and ensuring that the pressure is accurately applied to the deep vein puncture under the clavicle.

[0023] To facilitate adjustment of the length of lever 3 to accommodate different puncture points on different patients, lever 3 comprises a square sleeve 31 and a square rod 32. A hinge shaft 310 is fixedly mounted on both sides of the square sleeve 31, and the square rod 32 is slidably mounted within the interior of the square sleeve 31. A fastening bolt is provided on the upper surface of the end of the square sleeve 31 that faces the pressure rod 4, for securing the square rod 32 in its relative position within the square sleeve 31.

[0024] The upper surface of the square rod 32 at one end away from the mounting base 1 passes through the lower surface and may be provided with a through hole 321, and the pressure rod 4 may be movably arranged in the through hole 321. The outer side surface of the through hole 321 is provided with a fastening bolt for fastening the relative position of the pressure rod 4 in the through hole 321. Specifically in this embodiment, the cross-sections of the pressure rod 4 and the through hole 321 are both square-shaped structures, and the pressure rod 4 may be movably arranged in the through hole 321. By being able to be adjusted up and down, it is convenient to deal with patients of different body types. For example, for patients with larger bodies, the pressure rod 4 can be retracted upward. When the patient has a smaller body, the pressure rod 4 can be pushed downward so that it can quickly approach the puncture point, shortening and reducing the propulsion stroke of the lifting device 5.

[0025] When the pressure retaining rod 4 is pressed down, its lower end surface can be in parallel contact with the puncture point. The lower end of the pressure rod 4 is hinged with a T-shaped pressing block 41, and the lower end of the pressure rod 4 and the T-shaped pressing block 41 are detachably connected by bolts and nuts.

[0026] The upper end of the rotating shaft 120 extends beyond the upper surface of the rotating drum 21. A circular stopper 130 is fixedly attached to the upper end of the rotating shaft 120. The outer diameter of the stopper 130 is equal to the outer diameter of the rotating drum 21. This arrangement prevents the rotating drum 21 from dislodging from the rotating shaft 120. A thrust ball bearing 6 is mounted on the upper surface of the stopper 130. The lower surface of the thrust ball bearing 6 is fixedly connected to the upper surface of the stopper 130, and the upper surface of the thrust ball bearing 6 is fixedly connected to the bottom of the lifting device 5. This arrangement prevents rotational interference of the lifting device 5 caused by the fixed structure when the support arm 2 rotates on the rotating shaft 120.

[0027] refer to Figure 2 Specifically, the lifting device 5 adopts an electric push rod. The mounting base 1 is provided with an internal cavity, in which a controller 7 and a battery 8 are provided, and a control button 9 is provided on the outer surface. The electric push rod is fixed to the upper surface of the thrust ball bearing 6, and the telescopic end of the electric push rod abuts against the lower surface of the lever 3. The controller 7 receives instructions through the control button 9 and drives the electric push rod to rotate forward and reverse, so as to drive the lifting and lowering of the telescopic end of the electric push rod, and then drive the lever 3 to realize the tightening and loosening of the pressure rod 4. The battery 8 is used to provide the working voltage. In this embodiment, the controller 7 uses the STM32G031 main control board. The electric push rod uses TiMOTION TNA-08. The control button 9 includes a switch button 91 of the starting device, a forward button 92 for the rising telescopic end of the electric push rod, and a reverse button 93 for the falling telescopic end of the electric push rod.

[0028] In order to allow the end of the lever 3 abutting the electric push rod to be pulled down as the telescopic end of the electric push rod descends, waist-shaped plates 311 are provided on both sides of the bottom edge of the square sleeve 31, and the waist-shaped plates 311 are located directly above the electric push rod. A crossbar 51 is provided at the telescopic end of the electric push rod, and a waist-shaped hole 3111 is provided on the waist-shaped plate 311. The crossbar 51 is slidably arranged in the waist-shaped hole 3111. With this arrangement, when the puncture site stops bleeding, the reverse button of the electric push rod is pressed, and the telescopic end descends, and the pressure rod 4 provided on the lever 3 can be lifted accordingly.

[0029] To facilitate real-time observation of compression pressure data by medical personnel, a pressure sensor 10 is provided on the T-shaped pressure block 41. The detection end of the pressure sensor 10 is exposed to the compression surface at the bottom end of the T-shaped pressure block 41. The upper surface of the square sleeve 31 is provided with a display screen 11 for feedback of the pressure sensor 10 value. The output end of the pressure sensor 10 is electrically connected to the input end of the controller 7, and the display screen 11 is electrically connected to the output end of the controller 7. At the same time, to prevent the electric push rod from losing control and causing its telescopic end to continuously rise, a downward pressure limit threshold is preset in the controller 7. When the real-time pressure value detected by the pressure sensor 10 exceeds the limit threshold, the controller 7 drives the electric push rod to stop working.

[0030] In order to prevent the support arm 2 from shaking when the device is in use, a fastening bolt is provided on the outer surface of the rotating drum 21 . The fastening bolt is threadedly connected to the rotating drum 21 . When the fastening bolt is tightened, its end will abut against the outer wall of the rotating shaft 120 .

[0031] The working principle of the subclavian deep vein compression hemostat is as follows: when the forward button is pressed, the telescopic end of the electric push rod rises. Since the middle part of the lever 3 is hinged to the top of the support arm 2, the telescopic end rises to lift one end of the lever 3, and the other end of the lever 3, which is the end with the pressure rod 4, descends. The lower end of the pressure rod 4 is used to align with the puncture point. When the pressure rod 4 is pressed down, it presses the puncture point to compress and stop bleeding.

[0032] The method of using the subclavian deep vein compression hemostat is as follows: place the square base plate 110 under the patient's back on the shoulder side, rotate the support arm 2 horizontally, adjust the length of the lever 3 and the position of the pressure rod 4 on the through hole 321 of the lever 3 according to the position of the puncture point, then adjust the T-shaped pressure block 41 at the lower end of the pressure rod 4 so that the bottom surface of the T-shaped pressure block 41 and the skin surface of the puncture point remain in a relatively parallel position and are aligned with the puncture point; tighten the fastening bolts on the outer surface of the rotating cylinder 21 to prevent the support arm 2 from swinging. Press the forward button to start the electric push rod, which drives the pressure rod 4 to press down through the lever 3 mechanism. The downward force will be fed back to the display screen 11 in real time through the pressure sensor 10. When the standard value of the pressing force is reached, turn off the forward button, the electric push rod will stop rotating, and the pressure rod 4 will maintain the action of pressing to stop bleeding. At this time, the medical staff will be able to free their hands and perform other medical tasks; when the compression time is reached, press the reverse button, the telescopic end of the electric push rod will drop, and the lever 3 will be pulled down together, and the end with the pressure rod 4 will be loosened from the puncture point. At this time, loosen the fastening bolts on the outer surface of the rotating cylinder 21, rotate the support arm 2 to the side of the patient, and finally remove the device through the square base plate 110.

[0033] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the scope of protection of the present invention.
