Description

Technical Field

[0001] The utility model relates to the technical field of medical device design, in particular to a rapid humidification device for producing collagen membranes. Background Art

[0002] Among absorbable membranes, collagen membranes have become ideal materials for biomembranes that guide tissue regeneration due to their good biocompatibility, degradability, low immunogenicity, and operability. Collagen is the main water-insoluble fibrin and extracellular matrix that form the skeleton outside the cell. Collagen is abundant in mammals, accounting for about 20% to 30% of the protein content in humans or other animals. It is mainly distributed in tissues such as cartilage, skin, and tendons, and plays a variety of functions for the animal body, such as support, protection, and connection. When collagen is used as a medical biomaterial, in order to keep it in the appropriate morphology and strength according to the applicable part and purpose, it usually needs to be dried into a dense film or freeze-dried into a loose sponge;

[0003] As for the method of drying collagen solution into dense film, it is difficult to ensure uniform drying during the drying process of large quantities of collagen solution, and the moisture content is low after drying, which will cause problems in some subsequent production operations and quality control of finished products. To increase the moisture content of the film, the film can be placed in a high humidity environment to allow the film to absorb and increase the moisture content, or directly spray atomized water droplets. However, the former has slow adsorption and takes a long time, and the latter is difficult to atomize evenly, and large water droplets are prone to appear, resulting in reduced product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a rapid humidification device for producing collagen membranes, including the following technical solutions:

[0005] The present application discloses a rapid humidification device for producing collagen membranes, comprising a shell, a fan, and a nozzle. The shell is a tubular structure, comprising a rear end and a front end. The fan and the nozzle are on one side of the rear end. The nozzle is fixed to the bottom of the rear end, and the nozzle faces the interior of the shell. The fan is fixed inside the shell.

[0006] Preferably, the housing is an inverted U-shaped structure, with the two ends being a rear end and a front end respectively; the fan and the nozzle are located on the rear end side.

[0007] Preferably, the fan is fixed on the casing, the direction of the fan is toward the top channel of the casing, and the angle between the tangent planes of the fan and the casing is 0°~90°.

[0008] Preferably, the bottom of the rear end has a bending portion folded inwardly, and a collecting groove is provided in the bending portion for collecting droplets sliding down the inner surface of the shell and droplets falling after being sprayed by the nozzle.

[0009] Preferably, the bottom of the front end has a bent portion folded inwardly, and a collecting groove for collecting droplets sliding down the inner surface of the shell is provided in the bent portion.

[0010] Preferably, the nozzle and the rear end bottom are tightly connected to seal the rear end bottom.

[0011] Preferably, the nozzle is a structure with adjustable spray volume.

[0012] Preferably, the front end bottom has an opening.

[0013] Beneficial effects of the utility model:

[0014] 1. Through the structural design of the present application, two methods of adjusting the water content of the membrane can be realized at the same time: placing the membrane in a high humidity environment to allow the membrane to absorb and increase the water content and directly spraying atomized droplets onto the membrane surface;

[0015] 2. The U-shaped structure design can provide buffering to prevent the nozzle from directly facing the membrane, causing large amounts of liquid to fall on the membrane surface;

[0016] 3. By adjusting the spray volume of the nozzle and the time the membrane is in the device, the degree and speed of increase in membrane moisture content can be controlled, and adjustments can be effectively made according to actual conditions and needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model is further described in detail in conjunction with the embodiments below. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] Embodiment 1:

[0021] In this embodiment, the shape of the opening 5 at the bottom of the front end 102 is consistent with the shape of the mold, but is larger in size. When in use, the mold with the dried collagen film is placed under the opening 5, leaving a certain gap in the middle;

[0022] After the water is sprayed out from the nozzle 2 in atomized form, the spray volume is small, and larger droplets fall back to the bottom of the front end 102 from around the nozzle 2 for recovery, while smaller droplets move toward the front end 102 through the top channel of the housing 1 after passing through the airflow blown out by the fan 3. During the process, the droplets evaporate, increasing the humidity of the airflow. The airflow becomes high-humidity air without droplets.

[0023] After passing through the opening 5, the air flow diffuses from the gap between the opening 5 and the mold to the surroundings, so that the surface of the collagen film maintains a high humidity environment and the water content of the film increases slowly.

[0024] This embodiment is equivalent to placing the membrane in a high humidity environment to allow the membrane to absorb and increase the moisture content. The longer the placement time, the more the membrane moisture content increases; the shorter the placement time, the less the membrane moisture content increases.

[0025] Embodiment 2

[0026] In this embodiment, the opening 5 at the bottom of the front end 102 is in the shape of a capsule, and its length is longer than the mold. When in use, the device is placed on a conveyor belt, and the conveyor belt moves slowly from one side to the other side, passing through the middle position below the opening 5;

[0027] After the water is sprayed out from the nozzle 2 in atomized form, the spray volume is large. Large droplets fall from around the nozzle 2 back to the bottom of the front end 102 for recovery. Small droplets move toward the front end 102 through the top channel of the housing 1 after passing through the airflow blown out by the fan 3. During the process, the droplets evaporate, increasing the humidity of the airflow. The humidity gradually increases to near saturation, making it impossible for the droplets to continue to evaporate. The airflow becomes high-humidity air containing smaller droplets. As the airflow continues to pass through the housing 1, the droplets continue to be adsorbed on the inner surface of the housing 1. The droplets aggregate and slide down, and are collected through the curling edges at the bottom of the rear end 101 and the bottom of the front end 102 to avoid dripping through the opening 5.

[0028] The airflow continues to pass through the opening 5, and the mold moves slowly from one side to the other side through the conveyor belt. After passing under the opening 5, the smaller droplets are evenly attached to the surface of the collagen film, while maintaining a high humidity environment, and the remaining airflow diffuses from the gap between the opening 5 and the mold to the surroundings, so that the film quickly and evenly absorbs water, and the water content of the film increases rapidly.

[0029] In this embodiment, the method of directly spraying atomized water droplets onto the membrane surface is equivalent to that of spraying the atomized water droplets directly onto the membrane surface. The main parameters affecting the degree of increase in water content are the spray volume of the nozzle 2 and the speed of the conveyor belt.

[0030] The spray volume of the nozzle 2 determines how much smaller liquid can pass through the front end 102 opening 5; the conveyor belt speed determines how long the membrane is exposed to the opening 5; adjusting the spray volume of the nozzle 2 and the conveyor belt speed can control the degree of increase in the water content of the membrane;

[0031] The air volume of the fan 3 is a secondary parameter. If it is too small, smaller droplets cannot enter the front end 102 of the housing 1, and are then ejected from the opening 5, and the airflow becomes high-humidity air without droplets. If it is too large, not only will larger droplets be easily blown to the front end 102, but the excessively fast ventilation speed will cause more smaller liquids to evaporate, and the airflow will become high-humidity air containing both smaller droplets and larger droplets.

[0032] Embodiment 3

[0033] In this embodiment, the shape of the opening 5 at the bottom of the front end 102 is consistent with the shape of the mold, but is larger in size. When in use, the mold with the dried collagen film is placed under the opening 5, leaving a certain gap in the middle;

[0034] After the water is sprayed out from the nozzle 2 in atomized form, the spray volume is large. Large droplets fall from around the nozzle 2 back to the bottom of the front end 102 for recovery. Small droplets move toward the front end 102 through the top channel of the housing 1 after passing through the airflow blown out by the fan 3. During the process, the droplets evaporate, increasing the humidity of the airflow. The humidity gradually increases to near saturation, making it impossible for the droplets to continue to evaporate. The airflow becomes high-humidity air containing smaller droplets. As the airflow continues to pass through the housing 1, the droplets continue to be adsorbed on the inner surface of the housing 1. The droplets aggregate and slide down, and are collected through the curling edges at the bottom of the rear end 101 and the bottom of the front end 102 to avoid dripping through the opening 5.

[0035] After the airflow passes through the opening 5, smaller droplets are uniformly attached to the surface of the collagen membrane, while maintaining a high humidity environment, and the remaining airflow diffuses to the surroundings from the gap between the opening 5 and the mold, so that the membrane quickly and uniformly absorbs water, and the water content of the membrane quickly and uniformly increases.

[0036] This embodiment is equivalent to placing the film in a high humidity environment and spraying atomized water droplets at the same time. The placement time and the spray volume of the nozzle 2 are controlled simultaneously. The longer the placement time, the greater the spray volume of the nozzle 2, and the more the water content of the film increases; the shorter the placement time, the smaller the spray volume of the nozzle 2, and the less the water content of the film increases.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
