Description

Technical Field

[0001] The utility model relates to the technical field of double-linked fluid mixing, in particular to a double-linked fluid mixing and delivery device. Background Art

[0002] With the development of society, the application of dual-fluid instant mixing products in many fields such as industrial bonding, architectural decoration, material maintenance, and medical treatment is increasing. Among them, there are two-component glues used for industrial bonding, architectural decoration, material maintenance, and dental materials. When the glue is sold and stored, the two liquid or paste components are placed separately. When used, the two fluid components are mixed to produce a chemical reaction to form an adhesive that firmly adheres to the target object. In medicine and surgery, there is also fibrin glue used as a surgical hemostatic agent or tissue adhesive. Fibrin glue is a biological glue made by mixing hemagglutinin and fibrinogen derived from human or animal blood. When used, the freeze-dried human or animal fibrinogen and thrombin are first dissolved separately, and then the two solutions are simultaneously applied or sprayed onto the tissue wound surface that needs to be treated. After the solutions are mixed, they quickly solidify to form fibrin glue. In addition to the above two dual-fluid instant mixing products, there are many other products.

[0003] At present, two types of delivery devices are usually used for dual-fluid instant mixing products. One type is a dual-mixing injection device (such as the Chinese patent No. 200780007402.2). The two injection barrels of the device are prefabricated as one body, and have a circular liquid outlet with two component channels separated. The liquid outlet is connected to an MA bayonet mixing tube, an MC bell-mouth mixing tube or a TMC threaded mixing tube, etc. The two injection barrels can also have their own separate circular liquid outlets, connected to an MB circular plug-in interface. During manufacturing, the two components are respectively loaded into two injection barrels. When in use, the components in the two injection barrels are pushed out of their respective injection barrels by the push rod, and are manually stirred and mixed. If a mixing tube is equipped, the two components are separated multiple times by the blades installed in the mixing tube after being squeezed out of the injection barrel, and then mixed, gradually mixed evenly, and reacted to form a product. The injection barrel of the double mixing injection device has been finalized and is easy to use. However, when it is necessary to prepare products with different volume mixing ratios of raw material components, it is difficult to flexibly replace different double mixing injection devices. In addition, the general injection barrel is large in size and difficult to use for mixing small volume components.

[0004] Another type of delivery device is an assembled type, which includes two independent syringes and a syringe holder (such as the Chinese patent No. 202010808927.3). The assembled double liquid mixing device includes a syringe holder. The use of the holder limits the syringe model, making it difficult to flexibly select other types of syringes according to different needs and prepare products with different raw material component volume mixing ratios.

[0005] Therefore, there is an urgent need for a universal dual fluid mixing and delivery device for mixing small-volume components and capable of flexibly preparing products with different raw material component volume mixing ratios. Utility Model Content

The models of the two syringes are the same or different. The push plate is provided with two groups of slot groups for positioning and fixing the push rod heads of the two syringes. Each group of slot groups includes multiple slots, and the slot widths of the multiple slots decrease from the outside to the inside; the two inlets of the three-way connector are respectively detachably connected to the liquid outlets of the two syringes, and the outlet of the three-way connector is detachably connected to the mixing tube.

DETAILED DESCRIPTION

[0027] In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the utility model are described in detail with reference to the accompanying drawings for the preferred embodiments of the utility model and their features and functions.

[0028] like Figure 1-5 As shown, the utility model provides a dual fluid mixing delivery device, including a push plate 1, a three-way connector 3, a mixing tube 4 and two syringes 2. The syringes 2 can be ordinary medical syringes or similar products. The models of the two syringes 2 can be the same (such as Figure 1-2 ) can also be different (such as Figure 3-5 As shown), the push plate 1 is provided with two groups of slot groups 11 for positioning and fixing the push rod heads of the two syringes 2, each group of slot groups 11 includes a plurality of slots 13, and the slot widths of the plurality of slots 13 decrease from the outside to the inside (as shown in FIG. Figure 7 As shown); a slot 13 is provided to accommodate different types of syringes 2, and an arc-shaped pressing groove 12 is also provided on the top of the push plate 1 to ensure that the two syringes 2 can be evenly stressed when pressed; the two inlets of the three-way connector 3 are respectively connected to the liquid outlets of the two syringes 2 in a detachable manner such as plug-in or screw connection, and the outlet of the three-way connector 3 is connected to the mixing tube 4 in a detachable manner such as plug-in or screw connection. The inlet of the mixing tube 4 is a bayonet, screw or round mouth, and the outlet of the mixing tube is a pointed head or a flat head. Specifically, the mixing tube 4 can adopt an MA bayonet mixing tube, an MC bell-mouth mixing tube, a TMC threaded mixing tube or a similar mixing tube.

[0029] If the same model of syringes are used, each syringe contains the same volume of components, and extruded at the same flow rate at the same time, the two fluid components can be mixed in equal volumes; if two different models of syringes are used to contain fluid components respectively, when the syringes are in a vertical state, the length of the fluid in the syringe is kept the same, and the syringe push rod is pushed at the same linear speed, the fluids can be mixed in different volume ratios. The volume ratio depends on the relative thickness of the two syringe barrels. Specific examples are shown in the table below:

[0030]

[0031] The mixing volume ratio is not only fixed but also variable: if two syringes of the same model are used, and one of the syringes is filled with fluid and the air in the syringe is expelled, and the other syringe is filled with less fluid than the previous syringe and the air in the syringe is not completely expelled, the push rods of the two syringes are kept in the same position, the device is in an inclined position, and the push plate is pushed, the two fluids will be mixed in a non-fixed volume ratio.

[0032] In another embodiment, a T-shaped pull rod 5 is further included, and the T-shaped pull rod 5 is located between the two syringes 2, and the bottom of the T-shaped pull rod 5 is screwed to the three-way connector 3. The T-shaped pull rod 5 cooperates with the push plate 1 to squeeze out the fluid in the syringe 2.

[0033] In another embodiment, a syringe fixing clamp 6 is also included, and the syringe fixing clamp 6 includes an upper clamp plate 61 and a lower clamp plate 62, one end of the upper clamp plate 61 is hinged to one end of the lower clamp plate 62, and the other end of the upper clamp plate 61 is connected to the other end of the lower clamp plate 62 by a lock buckle 63; two grooves 64 are symmetrically arranged on the opposite sides of the upper clamp plate 61 and the lower clamp plate 62, and an arc plate 68 is slidably arranged in the groove 64, and a sliding column 65 is connected to the bottom of the arc plate 68, and the sliding column 65 is slidably connected to the through hole at the bottom of the groove 64, and a limiting boss is arranged at the free end of the sliding column 65 to prevent the sliding column 65 from falling out of the through hole, and a spring 66 is sleeved on the sliding column 65, and one end of the spring 66 abuts against the bottom of the groove 64, and the other end abuts against the arc plate 68. The syringe 2 is fixed by the syringe fixing fixture 6 so that the syringe barrel of the syringe is clamped by two arc-shaped plates 68 . The arrangement of the arc-shaped plates 68 can clamp syringes 2 of different models.

[0034] As a preferred embodiment, a rubber pad 69 is adhered to the arc plate 68, and the rubber pad 69 cooperates with the syringe 2. On the one hand, the syringe fixing clamp 6 prevents damage to the syringe 2, and on the other hand, the friction is improved to make the fit tighter and prevent the syringe 2 and the syringe fixing clamp 6 from slipping.

[0035] As a preferred embodiment, the upper clamping plate 61 and the lower clamping plate 62 are both provided with a semicircular groove 67 adapted to the T-shaped pull rod 5. The syringe fixing fixture 6 not only clamps the syringe 2, but also clamps the T-shaped pull rod 5, further enhancing the structural stability.

[0036] The above description is only the preferred embodiment of the utility model, not all embodiments. Anyone should be aware that structural changes made under the inspiration of the utility model, and all technical solutions that are the same or similar to the utility model, belong to the protection scope of the utility model.
