Description

Technical Field

[0001] This application relates to the field of blood splash prevention technology, and in particular to a blood splash prevention device for removing an intra-aortic balloon counterpulsation catheter. Background Technology

[0002] During the removal of an intra-aortic balloon pump (IABP), the sheath and catheter are typically removed as a single unit. Blood is allowed to flow from the arterial puncture site for several seconds to clear any blood clots attached to the catheter. Manual pressure is then applied above the puncture site for 30 minutes. This process, with blood flowing from the puncture site, is extremely prone to causing blood splatter, increasing the occupational exposure risk for healthcare workers.

[0003] Currently, existing protective technologies have significant limitations: 1. Existing equipment cannot adapt to different patients' leg shapes and lacks an effective sealing structure, resulting in a high rate of bleeding and a high risk of cross-infection; 2. After blood adheres to the observation window, the device needs to be opened or instruments inserted to wipe it, which prolongs the operation time, disrupts the sterile environment, and increases the risk of infection.

[0004] Therefore, there is an urgent need to develop a special protective device that combines dynamic sealing capability, self-maintenance function of operating view and rapid assembly characteristics, so as to improve operational safety and efficiency while ensuring isolation effect. Utility Model Content

[0005] To address the problems existing in the background art, this utility model proposes a device for preventing blood splashing during the removal of an intra-aortic balloon counterpulsation catheter.

[0006] The technical solution for the blood splash prevention device during aortic balloon counterpulsation catheter removal provided in this application is as follows: A device for preventing blood splashing during removal of an intra-aortic balloon counterpulsation catheter includes a main protective part and an adjustable restraint part. The main protective part is made of transparent material and has a rectangular hollow structure. An inclined surface is provided at the front end of the main protective part, and an observation window is installed on the inclined surface. Operation through holes are provided at the upper ends of the left and right sides of the main protective part, and placement slots are provided at the lower ends of the left and right sides of the main protective part. The main protective part is placed across the patient's leg through the placement slots.

[0007] Adjustable restraints are also installed on the placement slots on both sides of the main protective part. The adjustable restraints are used to wrap the patient's legs and are detachable.

[0008] It also includes a support bracket, which is placed under the patient's legs, and the lower end of the main protective part can be snapped into the support bracket.

[0009] Furthermore, the observation window is made of transparent glass, and movable glass push plates are provided on both sides of the observation window. The glass push plates are sealed to the observation window, and a movable scraping mechanism is installed in the middle of the observation window.

[0010] Furthermore, the scraping mechanism includes a chute, a first slider, a handle, a guide rail, a second slider, and a scraper. A chute is symmetrically provided on the inclined surface at the front end of the main protective part. A first slider is slidably arranged in the chute. A handle is installed between the upper ends of the two first sliders. A guide rail is symmetrically installed inside the main protective part. A second slider is slidably arranged on the guide rail. The first slider and the second slider are strong magnets. A scraper is installed between the two second sliders.

[0011] Furthermore, the scraper is made of rubber and is in close contact with the inner side of the observation window.

[0012] Furthermore, a hanging rack is installed on the placement slot, and latches are evenly arranged at the front end of the hanging rack, with the latches having a mushroom-shaped structure.

[0013] Furthermore, the adjustable restraint part includes a rigid connecting frame, a flexible pad, and a restraint strap. The rigid connecting frame has through holes evenly arranged on it, which cooperate with the buckle. A flexible pad is installed on the inner side of the rigid connecting frame. The flexible pad is made of a deformable material. A restraint strap is installed on the inner side of the flexible pad, and the lower end of the restraint strap extends out of the lower end of the flexible pad.

[0014] Furthermore, the support bracket has a rectangular structure, an arc-shaped groove is provided at the upper end of the support bracket, and a protective pad is also installed at the upper end of the support bracket. The protective pad is a detachable structure.

[0015] Beneficial effects Compared with the prior art, this utility model provides a device for preventing blood splashing during the removal of an intra-aortic balloon counterpulsation catheter, which has the following beneficial effects: 1. In this utility model, the adjustable restraint part is locked to the mushroom-shaped buckle of the hanging frame through a rigid connecting frame. Combined with the adaptive deformation of the flexible pad and the cross binding of the restraint strap, a tight enclosure and seal of the limb's curved surface is achieved, resulting in a low blood leakage rate and thus preventing the risk of occupational exposure to blood.

[0016] 2. The magnetic suction linkage scraping mechanism of this utility model allows medical staff to clean the observation window without damaging the seal. After blood adheres to the observation window, there is no need to open the window or insert instruments throughout the process, reducing operation time, avoiding damage to the sterile environment, and avoiding the risk of infection.

[0017] 3. In this utility model, the adjustable restraint part and the protective pad are disposable consumables and can be disassembled and replaced to avoid cross-infection between patients. The sleeve design with operating holes isolates medical staff from contact with blood, and the highly absorbent protective pad of the support bracket can immediately absorb exudate and reduce the risk of biological contamination. At the same time, it reduces the workload of medical staff in changing bed sheets and cleaning. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5This utility model provides a blood splash prevention device for removing an intra-aortic balloon counterpulsation catheter, comprising a main protective part 1 and an adjustable restraint part 2. The main protective part 1 is made of transparent material and has a rectangular hollow structure. The front end of the main protective part 1 has an inclined surface with an observation window 11 installed on the inclined surface. The upper ends of the left and right sides of the main protective part 1 have operation through holes 12 with sleeves installed on them. The lower ends of the left and right sides of the main protective part 1 have placement grooves 13, through which the main protective part 1 is placed across the patient's leg. The adjustable restraint part 2 is also installed on the placement grooves 13 on both sides of the main protective part 1. The adjustable restraint part 2 is used to wrap the patient's leg and is detachable. It also includes a support bracket 3, which is placed under the patient's leg. The lower end of the main protective part 1 can be snapped into the support bracket 3.

[0027] In the above technical solution, before removing the intra-aortic balloon counterpulsation pump (IABP) from the patient, the support stent 3 is first placed under the patient's leg to support the leg. Then, the main protective part 1 is placed across the patient's leg through the placement slot 13. The two ends of the patient's leg are then bound to the placement slot 13 through the adjustable restraint part 2, so that the space inside the main protective part 1 is sealed. The transparent main protective part 1 and the observation window 11 can provide a clear internal view. Medical staff can perform the removal operation through the operating through hole 12. When performing critical operations such as removing the IABP catheter, the risk of blood splashing can be avoided.

[0028] See Figures 1-3 As shown, as a preferred technical solution in this embodiment, the observation window 11 is made of transparent glass, and movable glass push plates 101 are provided on both sides of the observation window 11. The glass push plates 101 are sealed to the observation window 11, and a movable scraping mechanism 110 is installed in the middle of the observation window 11.

[0029] In the above technical solution, when performing critical operations such as removing the IABP catheter, blood will flow from the arterial puncture site for several seconds to remove thrombi attached to the catheter. This process is prone to causing blood splashing. Since the direction of blood splashing is not fixed, blood can easily adhere to the transparent main protective part 1 and the inner wall of the observation window 11, affecting the field of vision. Therefore, the scraping mechanism 110 can accurately scrape the inner wall of the observation window 11 to facilitate subsequent operations. At the same time, the glass push plate 101 can be pushed open. After the blood splashing is over, the glass push plates 101 on both sides of the observation window 11 can be pushed open to allow for the addition of gauze as needed.

[0030] It should also be noted that when the entire device is removed, medical staff need to press the wound with one hand. At this time, they can first press through the glass push plates 101 on both sides of the observation window 11. After the main protective part 1 is separated from the support bracket 3, they can then press through the gap between the main protective part 1 and the support bracket 3, which facilitates the rapid removal of the entire device.

[0031] See Figure 3 As shown, in a preferred embodiment, the scraping mechanism 110 includes a groove 1101, a first slider 1102, a handle 1103, a guide rail 1104, a second slider 1105, and a scraper 1106. The groove 1101 is symmetrically provided on the inclined surface at the front end of the main protective part 1. The first slider 1102 is slidably arranged in the groove 1101. The handle 1103 is installed between the upper ends of the two first sliders 1102. The guide rail 1104 is symmetrically installed inside the main protective part 1. The second slider 1105 is slidably arranged on the guide rail 1104. The first slider 1102 and the second slider 1105 are strong magnets. The scraper 1106 is installed between the two second sliders 1105.

[0032] See Figure 3 As shown, in this preferred embodiment, the scraper 1106 is made of rubber and is in close contact with the inner side of the observation window 11.

[0033] In the above technical solution, slider 1102 is located on the outside of the main protective part 1, and slider 2105 is located on the inside of the main protective part 1. Slider 1102 and slider 2105 are only magnetically attracted, so that when slider 1102 slides, the inside of the main protective part 1 is sealed, and no bleeding will occur, thus avoiding the risk of cross-infection.

[0034] When blood splashes onto the inside of the observation window 11, the handle 1103 drives the slider 1102 to reciprocate within the groove 1101. The slider 1102 can drive the scraper 1106 to move synchronously via the slider 2 1105. The scraper 1106 can then accurately clean the inside of the observation window 11, ensuring that the observation window 11 does not obstruct the field of vision while forming a protective barrier.

[0035] See Figure 4 As shown, as a preferred technical solution in this embodiment, a hanging bracket 131 is installed on the placement slot 13, and latches 132 are evenly arranged at the front end of the hanging bracket 131. The latches 132 have a mushroom-shaped structure.

[0036] See Figure 4As shown, as a preferred technical solution of this embodiment, the adjustable restraint part 2 includes a rigid connecting frame 21, a flexible pad 22, and a restraint strap 23. The rigid connecting frame 21 has through holes evenly arranged on it, and the through holes cooperate with the buckle 132. The flexible pad 22 is installed on the inner side of the rigid connecting frame 21. The flexible pad 22 is made of a deformable material. The restraint strap 23 is installed on the inner side of the flexible pad 22, and the lower end of the restraint strap 23 extends out of the lower end of the flexible pad 22.

[0037] In the above technical solution, the adjustable restraint part 2 is a disposable consumable. During installation, the adjustable restraint part 2 is inserted into the latch 132 at the front end of the bracket 131 through the through hole on the rigid connecting frame 21, thereby realizing the function of fixing the adjustable restraint part 2. The adjustable restraint part 2 is easy to install and remove, which not only ensures the convenience of operation and the protective effect, but also avoids the risk of cross-infection.

[0038] When fixing and sealing the patient's leg, the rigid connecting frame 21 can be clamped onto the patient's leg, and the flexible pad 22 can adapt to the size of the patient's leg. Then, the binding strap 23 is tied tightly to the patient's leg to ensure the sealing of the bottom of the flexible pad 22 after it is closed, so as to avoid blood leakage and thus prevent cross-infection.

[0039] It should be noted that the lower end of the restraint strap 23 is also equipped with a hook and loop fastener, which allows the restraint strap 23 to be attached via the hook and loop fastener, making it easy to operate and disassemble later.

[0040] See Figure 5 As shown, in this preferred embodiment, the support bracket 3 has a rectangular structure, an arc-shaped groove is provided at the upper end of the support bracket 3, and a protective pad 31 is also installed at the upper end of the support bracket 3. The protective pad 31 is a detachable structure.

[0041] In the above technical solution, the protective pad 31 is made of highly absorbent material. When blood splashes, the protective pad 31 can quickly absorb the blood seepage and fluid accumulation that may occur during the operation, keeping the operation area and surrounding environment dry and clean. The protective pad 31 is a disposable consumable that can be easily removed and replaced from the place of use, simplifying the operation and cleaning process and improving the convenience and hygiene standards of clinical use.

[0042] The working principle of this utility model is as follows: S1: Placement of support bracket The support bracket 3 is placed under the patient's leg, and its upper arc-shaped support and protective pad 31 provide stable support for the leg; the protective pad 31 is made of highly absorbent material to absorb blood or fluid that may seep out during the operation and keep the operation area clean.

[0043] S2: Install and secure the main protective unit. The main protective part 1 is placed across the patient's leg through the placement slot 13 at the bottom, so that its rectangular hollow structure covers the puncture operation area; the adjustable restraint part 2 is installed through the hangers 131 on both sides of the placement slot 13, and the through hole of the rigid connecting frame 21 is aligned with the mushroom-shaped buckle 132 and locked in place to ensure that the main protective part 1 and the leg form a sealed space.

[0044] S3: Seal and reinforce the legs. Adjust the flexible pad 22 of the adjustable restraint part 2 to fit the contour of the patient's leg, and use the restraint straps 23 to cross and tighten the leg to achieve a tight enclosure of the bottom of the flexible pad 22 to prevent blood leakage. At this time, a completely sealed operating space is formed inside the main protective part 1.

[0045] S4: Perform extubation and emergency cleaning. Medical staff can remove the catheter through the operating holes 12 (with built-in sleeves) on both sides of the main protective part 1. If blood splashes onto the inner wall of the observation window 11 and affects the field of vision, the outer handle 1103 can be pushed to drive the slider 1102 to slide along the slide groove 1101. The inner slider 1105 and the rubber scraper 1106 are driven by magnetic adsorption to move along the guide rail 1104 to scrape away the bloodstains on the inner side of the observation window 11 and ensure a clear field of vision.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
