A laminar flow bed air vent curtain device

Abstract

This utility model discloses a laminar flow bed air vent curtain device, including a laminar flow bed, a bed frame, and an air intake fan. A canopy frame is fixedly connected to the side of the bed frame, and a protective canopy is movably connected to the canopy frame. An air vent blocking component is detachably installed on the air intake fan. The air vent blocking component includes a fixed base, and two pipe clamps are fixedly connected to the fixed base. A protective cover for preventing the canopy from blocking the air intake of the air intake fan is detachably installed on the pipe clamps. With the above device, when the canopy is too long or may sag due to airflow, the auxiliary pulley on the fixed base cooperates with the pressure pulley on the side of the laminar flow bed. The torsion spring inside the pressure pulley clamps and fixes the folded canopy, preventing the canopy from being attracted by the airflow of the air intake fan and blocking the protective cover. This ensures unobstructed airflow to the air intake fan, maintains stable clean airflow in the laminar flow bed, and reduces the weakening of air purification effect and the risk of patient infection caused by the canopy blocking the air intake.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a laminar flow bed air vent curtain device. Background Technology

[0002] In the fields of medical and biological experiments, a clean local environment is crucial for the protection of vulnerable populations and the safety of experimental samples. In traditional ward and laboratory environments, there are a large number of pollutants such as microorganisms and dust particles in the air, which can easily lead to infection in immunocompromised patients, such as those undergoing chemotherapy for leukemia or hematopoietic stem cell transplant patients. It can also interfere with the results of biological experiments that have strict environmental requirements. Laminar flow beds, through air purification technology, form a vertical unidirectional airflow in a local area, allowing the airflow to flow along parallel streamlines at a uniform cross-sectional velocity, effectively reducing air turbulence and greatly reducing the concentration of dust and microorganisms in the area.

[0003] Bottom-ventilated laminar flow beds, widely used in the medical field, create a clean space through a circulation pattern of bottom air intake and top air exhaust, providing a sterile environment for immunocompromised patients. However, the accompanying tents often obstruct the bottom vents in practical applications due to improper operation or design flaws. When the tents sag, wrinkle, or accidentally cover the vents, the airflow path is blocked, leading to turbulent laminar airflow. The wind speed and pressure in the clean area are difficult to maintain stability, weakening the air purification effect and increasing the risk of infection for patients.

[0004] To address these issues, this invention provides a laminar flow bed vent curtain device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laminar flow bed vent curtain device, which solves the problem mentioned above where the airflow path is obstructed when the curtain droops, wrinkles, or accidentally covers the vent, leading to turbulent laminar airflow, making it difficult to maintain stable wind speed and wind pressure in the clean area, weakening the air purification effect, and increasing the risk of infection for patients.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laminar flow bed vent curtain device, comprising a laminar flow bed, a bed frame, and an air inlet fan. A canopy frame is fixedly connected to the side of the bed frame, and a protective canopy is movably connected to the canopy frame. An vent blocking assembly is detachably installed on the air inlet fan. The vent blocking assembly includes a fixed base, and two pipe clamps are fixedly connected to the fixed base. A protective cover for preventing the canopy from blocking the air inlet of the air inlet fan is detachably installed on the pipe clamps.

[0007] Preferably, the back of the fixed base is covered with adhesive tape for fixing to the air intake fan, and the sides of the protective cover are all fixedly connected with magnetic strips for adsorption to the air intake fan.

[0008] Preferably, an auxiliary pulley is fixedly connected to the fixed base, and a pressure pulley matching the auxiliary pulley is fixedly connected to the side of the laminar flow bed. The pressure pulley is equipped with a torsion spring inside, so that when the tent is too long, the tent can be folded and stored through the auxiliary pulley and the pressure pulley. The torsion spring inside the pressure pulley fixes the tent, preventing the tent from being drawn in by the wind force of the air intake fan and blocking the protective cover.

[0009] Preferably, a pulley system is fixedly connected to the side of the bed frame, and a protective curtain for protection is movably connected to the bottom of the pulley system.

[0010] Preferably, two rotating shafts are fixedly connected to the side of the laminar flow bed, and a rotating bed board is movably connected to the rotating shafts to facilitate the patient's getting on and off.

[0011] Preferably, a table is fixedly connected to the side of the laminar flow bed via a rotating arm, and the rotating arm consists of a rotating arm and a folding rod, so that the table can be stored on the side of the laminar flow bed, and a support frame is movably connected to the bottom of the table, so that the table can be supported on the laminar flow bed by the support frame when in use. Beneficial effects

[0012] This utility model provides a laminar flow bed air vent curtain device. Compared with the prior art, it has the following advantages:

[0013] (1) The air inlet curtain device of the laminar flow bed can be detachably installed on the fixed base by the pipe clamp to form an effective shielding and protection for the air inlet. When the curtain is too long or may sag due to the airflow, the auxiliary pulley on the fixed base cooperates with the pressure pulley on the side of the laminar flow bed. The torsion spring in the pressure pulley clamps and fixes the folded curtain, so as to prevent the curtain from being attracted by the airflow of the air inlet fan and blocking the protective cover, ensuring that the air inlet fan can enter smoothly, maintaining the stability of the clean airflow in the laminar flow bed, and reducing the weakening of the air purification effect and the risk of patient infection caused by the curtain blocking the air inlet.

[0014] (2) The protective curtain device for the air vent of the laminar flow bed can be flexibly adjusted by sliding the protective curtain suspended by the pulley group to meet the needs of different usage scenarios; the rotating bed board connected by the pivot can be flipped up and opened to facilitate patients getting on and off the bed. After use, it can be reset without affecting the integrity of the laminar flow space. The rotating arm is composed of a rotating arm and a folding rod, which can fold the table board and store it on the side of the laminar flow bed to save space. When in use, the table board is unfolded and supported by the bottom support frame to provide patients with a stable surface for placing items or performing operations. While ensuring the clean environment of the laminar flow bed, it optimizes the patient's user experience and the convenience of nursing operations. Attached Figure Description

[0023] 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. Example

[0024] Please see Figures 1 to 4 A laminar flow bed vent curtain device includes a laminar flow bed 1, a bed frame 2, and an air inlet fan 3. A canopy frame 6 is fixedly connected to the side of the bed frame 2, and a protective canopy 5 is movably connected to the canopy frame 6. An vent shielding assembly 4 is detachably installed on the air inlet fan 3. The vent shielding assembly 4 includes a fixed base 41, and two pipe clamps 43 are fixedly connected to the fixed base 41. A protective cover 42 for preventing the canopy 5 from blocking the air inlet of the air inlet fan 3 is detachably installed on the pipe clamps 43. A cover for fixing the air inlet fan 3 is attached to the back of the fixed base 41. The adhesive on the fan 3 and the side of the protective cover 42 are both fixedly connected with magnetic strips for adsorption to the fan 3. The fixed base 41 is fixedly connected with an auxiliary pulley 44, and the side of the laminar flow bed 1 is fixedly connected with a pressure pulley 45 that matches the auxiliary pulley 44. The pressure pulley 45 is provided with a torsion spring inside, so that when the tent 5 is too long, the tent 5 can be folded and stored through the auxiliary pulley 44 and the pressure pulley 45. The torsion spring inside the pressure pulley 45 fixes the tent 5, preventing the tent 5 from being attracted by the wind force of the fan 3 and blocking the protective cover 42.

[0025] When the laminar flow bed 1 is in use, the air vent shielding component 4 is first fixed to the air inlet of the air inlet fan 3 using the adhesive on the back of the fixing base 41. At the same time, the magnetic strip on the side of the protective cover 42 is used to enhance the adsorption stability, ensuring that the protective cover 42 firmly covers the air inlet. The tent 5 covers the tent frame 6. When the tent 5 is too long or droops due to airflow, the excess part can be folded and placed between the auxiliary pulley 44 and the pressure pulley 45. The torsion spring inside the pressure pulley 45 provides elastic pressure to clamp and fix the tent 5, preventing the tent 5 from being pulled towards the air inlet by the suction of the air inlet fan 3, thereby preventing the tent 5 from blocking the protective cover 42 and ensuring smooth air intake. The air inlet fan 3 normally draws in air through the hollow structure of the protective cover 42. After being purified inside the laminar flow bed 1, it forms a vertical unidirectional airflow, maintaining the stability of the wind speed and wind pressure in the clean area and reducing the risk of infection. Example

[0026] Please see Figures 1 to 4 This embodiment provides a technical solution based on embodiment one: a pulley group 7 is fixedly connected to the side of the bed frame 2, and a protective curtain 8 for protection is movably connected to the bottom of the pulley group 7. Two rotating shafts 10 are fixedly connected to the side of the laminar flow bed 1, and a rotating bed board 9 is movably connected to the rotating shaft 10 to facilitate the patient getting on and off. A table board 11 is fixedly connected to the side of the laminar flow bed 1 through a rotating arm 13, and the rotating arm 13 is composed of a rotating arm and a folding rod so that the table board 11 can be stored on the side of the laminar flow bed 1. A support frame 12 is movably connected to the bottom of the table board 11 so that the table board 11 can be supported on the laminar flow bed 1 by the support frame 12 when in use.

[0027] During operation, the protective curtain 8 is suspended by the pulley group 7 on the side of the bed frame 2. The protective curtain 8 can be slid to close or open the side of the laminar flow bed 1, flexibly adjusting the protection range. The rotating bed board 9 on the side of the laminar flow bed 1 is movably connected by the pivot 10 and can be flipped up to open, making it convenient for patients to get on and off the bed. After use, it is reset and closed without affecting the integrity of the laminar flow space. The table board 11 is connected to the side of the laminar flow bed 1 by the rotating arm 13 (composed of the rotating arm and the folding rod). When not in use, the table board 11 can be folded by the rotating arm 13 to fit against the side of the laminar flow bed 1, saving space. When in use, the table board 11 is unfolded and the bottom support frame 12 is lowered. The support frame 12 supports the surface of the laminar flow bed 1, forming a stable plane for patients to place items or perform operations.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During operation, the air vent shielding component 4 is first fixed to the air inlet of the air inlet fan 3 by the adhesive backing of the fixed base 41. The magnetic strip on the side of the protective cover 42 enhances the adsorption. The auxiliary pulley 44 on the fixed base 41 cooperates with the pressure pulley 45 on the side of the laminar flow bed 1. When the canopy 5 is too long, it is folded and placed between the two. The torsion spring inside the pressure pulley 45 clamps and fixes the canopy 5 to prevent it from being attracted by the airflow of the air inlet fan 3 and blocking the protective cover 42. The air inlet fan 3 draws in air through the protective cover 42 to form a clean airflow. The protective curtain 8 suspended by the side pulley group 7 of the bed frame 2 can slide to achieve side closure or opening. The rotating bed board 9 on the side of the laminar flow bed 1 is movably connected by the pivot 10 to facilitate patients getting on and off the bed. The table board 11 on the side of the laminar flow bed 1 is connected by the rotating arm 13. When not in use, it is folded to fit the side. When in use, it is unfolded and supported on the laminar flow bed 1 by the bottom support frame 12.
