Description

Technical Field

[0001] This utility model belongs to the field of surgical suture processing and drying technology, and specifically relates to a surgical suture drying device. Background Technology

[0002] Surgical sutures are a type of special thread used in surgical procedures for ligation and hemostasis, suturing and tissue repair. They can be divided into two types based on their material: absorbable surgical sutures and non-absorbable surgical sutures. The preparation process of surgical sutures mainly consists of the following steps: raw material selection and processing, melt plasticizing, extrusion molding, stretching and shaping, drying and cooling, quality inspection, sterilization and packaging.

[0003] Among them, surgical suture drying devices are a type of equipment used to dry and cool extruded surgical sutures. Currently, common surgical suture drying devices mainly consist of: a frame, a heating and drying component, a ventilation component, a control system, and other auxiliary accessories. In practical applications, the heating and drying component and the ventilation component work together to dry and cool the surgical sutures transported inside.

[0004] Most existing surgical suture drying devices do not have preheating recovery and reuse functions, and cannot recover and reuse the waste heat generated during the drying process. This not only easily leads to a certain degree of resource waste, but also causes the temperature of the working environment to rise due to the discharged waste heat, resulting in poor energy saving and environmental protection in the use of surgical suture drying devices.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a surgical suture drying device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a surgical suture drying device that can recover and reuse waste heat, thereby improving the energy efficiency and environmental friendliness of the surgical suture drying device.

[0008] To achieve the above objectives, a specific embodiment of this utility model provides a surgical suture drying device, including: a drying shell, an inner partition, a preheating and diversion mechanism, and a waste heat recovery mechanism.

[0009] The dryer housing is fixedly equipped with a pair of inner partitions, which divide the dryer housing into a preheating drying chamber, a drying chamber, and a cooling chamber.

[0010] The preheating and guiding mechanism is mounted below the drying chamber. The preheating and guiding mechanism includes an adsorption box, which is fixedly mounted below the drying chamber. An air inlet pipe is fixedly connected between the adsorption box and the drying chamber. A guide component is fixedly mounted on one side of the adsorption box. An exhaust fan is fixedly mounted inside the guide component. A connecting guide component is fixedly mounted on the side of the guide component away from the exhaust fan. Both sides of the connecting guide component are connected to guide pipes.

[0011] The waste heat recovery mechanism is mounted below the preheating and drying chamber. The waste heat recovery mechanism includes a heat exchange liquid tank, which is fixedly mounted below the preheating and drying chamber. A heat-conducting air duct is arranged inside the heat exchange liquid tank and is connected to the preheating and drying chamber.

[0012] In one or more embodiments of this utility model, multiple sets of evenly distributed flow guiding pipes are fixedly mounted on the upper part of the dryer casing. These multiple sets of flow guiding pipes are respectively connected to the preheating drying chamber, the drying chamber, and the cooling chamber. The flow guiding pipes serve to assemble and fix multiple sets of fans and to guide gas flow.

[0013] In one or more embodiments of this utility model, multiple sets of evenly distributed fans are fixedly installed inside each of the multiple sets of flow guide assembly pipes. By controlling the operation of the multiple sets of fans, outside air enters the dryer housing along the fan blades. A support is fixedly installed at the bottom of the dryer housing. The dryer housing, adsorption box, and heat exchange liquid box are assembled and fixed by the support. Multiple sets of heating resistance wires are arranged above the drying chamber. By controlling the operation of the multiple sets of heating resistance wires, the drying chamber is heated, thereby facilitating the drying of surgical sutures within the drying chamber.

[0014] In one or more embodiments of this utility model, a mesh frame is inserted into the adsorption box, and the mesh frame is arranged between the air inlet pipe and the guide component. The mesh frame serves to assemble and fix the adsorption filter screen.

[0015] In one or more embodiments of this utility model, an adsorption filter screen is fixedly installed inside the mesh frame, and the adsorption filter screen is located below the air inlet pipe. The adsorption filter screen adsorbs and filters the gas transported through the air inlet pipe, ensuring the safety of recovering and utilizing the waste heat gas in the preheating and drying chamber. A disassembly handle is fixedly connected to one end of the mesh frame outside the adsorption box. The mesh frame can be easily disassembled and assembled by applying force to the disassembly handle.

[0016] In one or more embodiments of this utility model, the air inlet of the exhaust fan is located inside the adsorption box, and ventilation holes are provided on the side of the guide member and the connecting guide member that are close to each other. The guide member and the connecting guide member are connected by the ventilation holes. This facilitates the transport of waste heat gas in the adsorption box to the connecting guide member along the ventilation holes by the exhaust fan.

[0017] In one or more embodiments of this utility model, each end of the pair of guide tubes opposite to the connecting conductor is fixedly connected to an exhaust pipe, which is connected to the preheating and drying chamber. This facilitates the transport of waste heat gas from the guide tubes to the preheating and drying chamber via the exhaust pipe. Furthermore, the diameter of the exhaust pipe at one end within the preheating and drying chamber is larger than the diameter at the other end. By setting the diameter of the exhaust pipe at one end within the preheating and drying chamber to be larger than the diameter at the other end, the waste heat gas can be transported into the preheating and drying chamber in a diffused state under the action of the exhaust pipe, thereby allowing the waste heat gas to preheat and dry the surgical sutures within the preheating and drying chamber.

[0018] In one or more embodiments of this utility model, the heat exchange liquid tank is filled with a heat exchange fluid. The heat exchange fluid absorbs heat from the gas transported through the heat-conducting air duct, thereby facilitating waste heat recovery from the gas. A drain pipe is fixedly connected to one side of the heat exchange liquid tank. The liquid inside the heat exchange liquid tank is discharged through the drain pipe.

[0019] In one or more embodiments of this utility model, a filling pipe is fixedly connected to one side of the heat exchange fluid tank. This facilitates the addition of a lower-temperature heat exchange fluid into the heat exchange fluid tank through the filling pipe. The horizontal height of the filling pipe is higher than that of the drain pipe, ensuring the stability of both the inlet and outlet flow of the drain pipe.

[0020] In one or more embodiments of this utility model, an exhaust heat-conducting pipe is fixedly connected to one side of the heat-conducting air duct inside the heat exchange liquid tank, and the exhaust heat-conducting pipe is installed through the heat exchange liquid tank. The gas after heat exchange is discharged through the exhaust heat-conducting pipe.

[0021] Compared with the prior art, the surgical suture drying device disclosed in this utility model can recover and utilize the waste heat during the drying process by setting a preheating and diversion mechanism and a waste heat recovery mechanism. This not only reduces the waste of resources, but also reduces the heating rate of the working environment, thus improving the energy efficiency and environmental protection of the surgical suture drying device during use.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figures 1 to 8As shown, a surgical suture drying device in one embodiment of the present invention includes a drying shell 1, an inner partition 101, a preheating and diversion mechanism 2, and a waste heat recovery mechanism 3.

[0035] like Figure 1 As shown, a pair of inner partitions 101 are fixedly installed inside the dryer housing 1, which divide the dryer housing 1 into a preheating drying chamber 102, a drying chamber 103, and a cooling chamber 104. The surgical sutures are pre-dried, dried, and cooled respectively through the preheating drying chamber 102, the drying chamber 103, and the cooling chamber 104.

[0036] like Figures 1 to 4 As shown, multiple sets of evenly distributed flow guide pipes 105 are fixedly mounted on the upper part of the dryer casing 1. The multiple sets of flow guide pipes 105 are connected to the preheating drying chamber 102, the drying chamber 103, and the cooling chamber 104, respectively. The flow guide pipes 105 serve to assemble and fix the multiple sets of fans 106 and to guide the gas flow.

[0037] like Figures 1 to 4 As shown, multiple sets of evenly distributed fans 106 are fixedly installed inside each set of airflow guide pipes 105. By controlling the operation of the multiple sets of fans 106, outside air enters the dryer housing 1 along the fan blades.

[0038] like Figures 1 to 4 As shown, a bracket 107 is fixedly mounted on the lower part of the dryer housing 1. The dryer housing 1, the adsorption box 201, and the heat exchange liquid box 301 are assembled and fixed by the bracket 107.

[0039] like Figures 1 to 4 As shown, multiple sets of heating resistance wires 108 are arranged above the drying chamber 103. By controlling the operation of the multiple sets of heating resistance wires 108, the drying chamber 103 is heated, thereby facilitating the drying of surgical sutures inside the drying chamber 103.

[0040] like Figures 1 to 3 As shown, the preheating and guiding mechanism 2 is mounted below the drying chamber 103. The preheating and guiding mechanism 2 includes an adsorption box 201, which is fixedly mounted below the drying chamber 103. The adsorption box 201 provides a temporary storage and filtration space for the waste heat gas guided by the intake pipe 202.

[0041] like Figures 1 to 2 As shown, a mesh frame 207 is inserted into the adsorption box 201, and the mesh frame 207 is arranged between the air inlet pipe 202 and the guide component 203. The mesh frame 207 serves to assemble and fix the adsorption filter screen 208.

[0042] like Figures 1 to 2As shown, an adsorption filter 208 is fixedly installed inside the mesh frame 207, and the adsorption filter 208 is located below the air inlet pipe 202. The adsorption filter 208 adsorbs and filters the gas transported by the air inlet pipe 202, ensuring the safety of recovering and utilizing the waste heat gas in the preheating and drying chamber 102.

[0043] Specifically, the adsorption filter 208 is an activated carbon adsorption filter.

[0044] like Figures 1 to 2 As shown, a disassembly handle 209 is fixedly connected to one end of the mesh frame 207 outside the adsorption box 201. The mesh frame 207 can be easily disassembled and assembled by applying force to the disassembly handle 209.

[0045] like Figures 1 to 2 As shown, an air inlet pipe 202 is fixedly connected between the adsorption box 201 and the drying chamber 103. This facilitates the transport of waste heat gas in the drying chamber 103 to the adsorption box 201 via the air inlet pipe 202.

[0046] like Figures 1 to 3 As shown, a flow guide 203 is fixedly mounted on one side of the adsorption box 201. The flow guide 203 guides the waste heat gas after adsorption and filtration inside the adsorption box 201.

[0047] like Figures 1 to 3 As shown, an exhaust fan 204 is fixedly installed inside the flow guide 203. The operation of the exhaust fan 204 is controlled to extract and transport the gas after adsorption and filtration in the adsorption box 201.

[0048] Specifically, the 204 exhaust fan is commercially available and can be purchased and used directly.

[0049] The air inlet of the exhaust fan 204 is located inside the adsorption box 201. Ventilation vents are provided on the sides of the guide member 203 and the connecting guide member 205 that are close to each other, allowing the guide member 203 and the connecting guide member 205 to connect. This facilitates the transport of waste heat gas from the adsorption box 201 to the connecting guide member 205 via the ventilation vents under the action of the exhaust fan 204.

[0050] like Figures 1 to 3 As shown, a connecting guide 205 is fixedly mounted on the side of the guide 203 away from the exhaust fan 204. The connecting guide 205 serves to connect the guide pipe 206 and the drying chamber 103, facilitating the transport of waste heat gas in the guide 203 to the guide pipe 206.

[0051] like Figures 4 to 8 As shown, both sides of the connecting guide 205 are connected to guide pipes 206. The guide pipes 206 serve to connect the connecting guide 205 and the exhaust pipe 210.

[0052] like Figure 4 As shown, each of the two guide pipes 206 has an exhaust pipe 210 fixedly connected to one end opposite to the connecting conductor 205. The exhaust pipe 210 is connected to the preheating and drying chamber 102. This facilitates the transport of waste heat gas conveyed in the guide pipes 206 to the preheating and drying chamber 102 via the exhaust pipe 210.

[0053] Specifically, the diameter of one end of the exhaust duct 210 inside the preheating and drying chamber 102 is larger than the diameter of the other end. By setting the diameter of one end of the exhaust duct 210 inside the preheating and drying chamber 102 to be larger than the diameter of the other end, the residual heat gas can be diffused and transported into the preheating and drying chamber 102 under the action of the exhaust duct 210, thereby allowing the residual heat gas to preheat and dry the surgical sutures inside the preheating and drying chamber 102.

[0054] like Figures 1 to 5 As shown, the waste heat recovery mechanism 3 is mounted below the preheating and drying chamber 102. The waste heat recovery mechanism 3 includes a heat exchange liquid tank 301, which is fixedly mounted below the preheating and drying chamber 102. The heat exchange liquid tank 301 serves to store the heat exchange fluid 303.

[0055] like Figures 1 to 5 As shown, the heat exchange liquid tank 301 is filled with heat exchange fluid 303. The heat exchange fluid 303 absorbs heat from the gas transported by the heat-conducting air duct 302, thus facilitating waste heat recovery from the gas transported by the heat-conducting air duct 302. A drain pipe 304 is fixedly connected to one side of the heat exchange liquid tank 301. The liquid inside the heat exchange liquid tank 301 is discharged through the drain pipe 304.

[0056] Specifically, water can be selected as the heat exchange fluid 303, and an external shut-off valve is connected to the drain pipe 304 in actual applications.

[0057] like Figures 1 to 5 As shown, a heat-conducting air duct 302 is arranged inside the heat exchange liquid tank 301, and the heat-conducting air duct 302 is connected to the preheating and drying chamber 102. This facilitates the transport of gas in the preheating and drying chamber 102 to the heat exchange liquid tank 301 along the heat-conducting air duct 302, thereby facilitating the absorption of heat from the gas transported in the heat-conducting air duct 302 by the heat exchange fluid 303.

[0058] like Figures 4 to 7 As shown, a liquid addition pipe 305 is fixedly connected to one side of the heat exchange liquid tank 301. This facilitates the addition of a lower-temperature heat exchange fluid 303 into the heat exchange liquid tank 301 through the liquid addition pipe 305.

[0059] Specifically, the horizontal height of the filling pipe 305 is higher than that of the drain pipe 304. This ensures the stability of the liquid inlet of the drain pipe 304 and the stability of the liquid outlet of the filling pipe 305.

[0060] like Figures 4 to 5 As shown, a heat-conducting air duct 302 is fixedly connected to an exhaust heat-conducting pipe 306 on one side inside the heat exchange liquid tank 301. The exhaust heat-conducting pipe 306 penetrates the heat exchange liquid tank 301. The gas after heat exchange is discharged through the exhaust heat-conducting pipe 306.

[0061] In practical use, the surgical sutures to be dried are transported into the drying chamber 1. The sutures are dried by controlling the operation of the fan 106 and the heating resistance wire 108. During the drying process, the air containing residual heat in the drying chamber 103 is transported to the adsorption box 201 along the air inlet pipe 202 under the action of multiple sets of fans 106. The residual heat air can be adsorbed and filtered by the adsorption filter screen 208.

[0062] Meanwhile, the operation of the exhaust fan 204 can be controlled to allow the filtered residual heat air in the adsorption box 201 to be transported to the preheating and drying chamber 102 along the connecting conductor 205, the guide pipe 206 and the exhaust pipe 210, thereby preheating and drying the surgical sutures in the preheating and drying chamber 102.

[0063] In addition, the gas containing residual heat in the preheating and drying chamber 102 is also transported to the heat exchange liquid tank 301 along the heat-conducting air duct 302 under the action of multiple sets of fans 106, and is discharged along the exhaust heat-conducting pipe 306 after exchanging heat with the heat exchange fluid 303.

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.
