Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a glue injection and dispensing device and an oxygenator preparation system. Background Art

[0002] With the continuous advancement of medical technology, the application of artificial organ support systems is becoming more and more extensive. Among them, oxygenators, as the core components that temporarily replace human lung function, play a vital role in cardiopulmonary surgery, intensive care treatment and extracorporeal circulation. The main function of the oxygenator is to remove carbon dioxide from venous blood and supplement oxygen to ensure that patients have sufficient oxygenated blood supply during surgery or treatment. The oxygenator contains complex microporous membranes and other structures, which need to be tightly sealed to prevent blood leakage. Glue injection can fill the gaps to ensure that the oxygenator does not leak during use and maintain the integrity of the blood flow path, which is crucial to maintaining blood purity, avoiding external contamination and protecting patient safety. The selected glue injection materials usually have good biocompatibility, which means that they do not cause immune reactions or have a negative impact on blood components. The glue injection layer can act as a protective barrier to reduce the possibility of direct contact between blood and non-biological materials of the oxygenator, and reduce the risk of thrombosis and inflammatory response. Glue injection can also enhance the stability of the internal structure of the oxygenator, especially for those parts containing tiny pipes and complex structures. Proper glue injection can strengthen weak links and prevent deformation or damage during mechanical stress or operation. The existing glue injection equipment has the problems of uneven glue injection and inconvenient maintenance. Utility Model Content

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] Please refer to Figures 1 to 4 , an embodiment of the present application provides a glue injection and dispensing device 100. The glue injection and dispensing device 100 includes: a base 101, a glue box 110, six positioning components 130 and six glue nozzles 120. The glue box 110 is fixed to the base 101 and has a hollow chamber 111, and the chamber 111 is used to accommodate glue. The positioning component 130 is fixed to the base 101 and is used to load the product to be injected with glue. One of the glue nozzles 120 is arranged between the glue box 110 and one of the positioning components 130. The six glue nozzles 120 are evenly arranged around the glue box 110. The glue nozzle 120 has a passage 1211 that runs through the glue nozzle 120. One end of the passage 1211 is connected to the chamber 111 of the glue box 110, and the other end of the passage 1211 is connected to the positioning component 130; wherein the glue nozzle 120 is detachably connected to the glue box 110.

[0033] The glue injection and dispensing device 100 provided in the embodiment of the present application can evenly distribute the glue in the glue box 110 to the corresponding positioning component 130 through the glue nozzle 120. At the same time, the glue nozzle 120 is detachably connected to the glue box 110, which is convenient for replacement of the glue nozzle 120, and further convenient for cleaning, maintenance and use of the glue injection and dispensing device 100, which is conducive to wide application.

[0034] The glue box 110 is a container with an open top, and the same number of mounting holes as the glue nozzles 120 are opened on the annular side. Each glue nozzle 120 is fixed in one of the mounting holes, and the mounting holes are evenly distributed around the axial line of the glue box 110, and the axial lines of all the mounting holes are in the same plane. In this way, the glue box 110 can evenly dispense glue outward through the six glue nozzles 120 during glue dispensing, with high glue injection efficiency and uniform glue dispensing.

[0035] In a feasible embodiment, an internal thread may be provided in the mounting hole of the glue box 110, and an external thread may be provided on the outside of the glue nozzle 120, and the glue nozzle 120 and the glue box 110 may be directly threadedly connected through the external thread and the internal thread. In a feasible implementation, the glue nozzle 120 has a main body 121 and a mounting portion 122, wherein the passage 1211 passes through the main body 121, and the mounting portion 122 is arranged around the outside of the main body 121. The mounting portion 122 is provided with a thread for threaded connection with the glue box 110. Furthermore, the main body 121 and the mounting portion 122 may be integrally formed or may be separately manufactured and then assembled. For example, the main body 121 may be as follows: Figure 2 In the conical structure shown, the main body 121 can be installed from the inside of the plastic box 110 to the outside through the mounting hole. The diameter of the conical bottom of the main body 121 is larger than the diameter of the mounting hole, and the main body 121 gradually decreases, or the portion that passes through the mounting hole is the same as the diameter of the mounting hole, and the diameter of the hole that passes through the mounting hole and is exposed to the outside of the plastic box 110 is smaller than the diameter of the mounting hole, until the diameter at the tip of the cone is the smallest. At this time, the mounting part 122 is sleeved on the portion of the main body 121 exposed to the outside of the plastic box 110, and the mounting part 122 has threads, which are screwed with the threads on the plastic box 110 and the main body 121.

[0036] In one possible implementation, Figure 1 As shown, six bottom plates 131 are further provided on the base 101, and one positioning mechanism is fixed on one bottom plate 131. In this way, the positioning mechanism on the bottom plate 131 can be replaced as a whole according to needs, so as to facilitate maintenance or replacement for products of different types and specifications, thereby improving the versatility of the glue injection and dispensing device 100 and facilitating wide applications.

[0037] In one possible implementation, Figure 3 to Figure 4 As shown, the positioning assembly 130 includes a loading mechanism 132. The loading mechanism 132 is detachably connected to the bottom plate 131, thereby realizing a detachable connection between the loading mechanism 132 and the base 101. The loading mechanism 132 is used to load the product to be injected with glue. The loading mechanism 132 is detachably connected to the bottom plate 131, which can facilitate the loading and unloading of the product to be injected with glue and the use of the product. Different loading mechanisms 132 can also be set according to products of different specifications, further improving the versatility of the equipment.

[0038] Further, such as Figure 3 to Figure 4 As shown, the positioning assembly 130 also includes a fixing member 133 and a pressing member 134, and the fixing member 133 and the pressing member 134 are connected to the bottom plate 131, and the loading mechanism 132 is arranged between the fixing member 133 and the pressing member 134. Specifically, the fixing member 133 is fixedly connected to the bottom plate 131 and fixed to one end of the loading mechanism 132 along the axial direction. The pressing mechanism is connected to the bottom plate 131 and is used to abut against the other end of the loading mechanism 132 along the axial direction. The pressing mechanism has a handle, and the loading mechanism 132 and the bottom plate 131 can be pressed by manipulating the handle. Further, a first limiting groove 1331 is also provided on the bottom plate 131. The first limiting groove 1331 is used to accommodate the protruding portion of the component of the loading mechanism 132 close to the fixing member 133. Specifically, the protruding portion can be a butterfly screw used to fix the loading mechanism 132 to the product to be injected. In this way, the clamping member 134 and the fixing member 133 not only fix the loading mechanism 132 in the axial direction of the loading mechanism 132, but the first limiting groove 1331 also fixes the loading mechanism 132 in the radial direction of the loading mechanism 132, further improving the reliability of the fixation of the loading mechanism 132, and improving the stability of the operation of the glue injection and dispensing device 100 during the glue injection and dispensing process. Furthermore, the fixing member 133 may also include a second limiting groove 1332. The second limiting groove 1332 may also be a structure corresponding to a different part of the component connecting the loading mechanism 132 and the fixing member 133. For example, the part where the loading mechanism 132 abuts against the fixing member 133 is a circular protrusion, and the fixing member 133 may be a circular concave, so that the limiting can be achieved from multiple angles, further improving the reliability of the fixation.

[0039] In a feasible implementation, the pressing member 134 is slidably connected to the base plate 131. In this way, the distance between the pressing member 134 and the fixing member 133 can be changed as the pressing member 134 slides, and then can be adjusted according to the loading mechanism 132 of different sizes, thereby improving the versatility of the glue injection and dispensing device 100. Further, the positioning assembly 130 also includes a sliding assembly, through which the pressing member 134 is slidably connected to the base plate 131. The sliding assembly includes a slider 1351 that can slide relative to the base plate 131. The pressing member 134 is fixedly connected to the slider 1351, so that the sliding of the slider 1351 drives the pressing member 134 to slide. Further, the sliding assembly can be a hand-cranked screw slide 135. The hand-cranked screw slide 135 includes a slider 1351, a screw assembly 1354 and a hand-cranked wheel 1352. The structure of the hand-cranked screw slide 135 is relatively existing and will not be repeated here. The hand-cranked screw slide 135 can be used to adjust the displacement of the slider 1351 through the hand-cranked wheel 1352. The high-precision ball screw is used, which allows it to maintain good position accuracy and repeatability during manual operation, and is suitable for occasions that require precise adjustment or positioning. The design of the ball screw reduces friction, making the hand feel smooth and easy to operate when pushed manually, without any jamming or jumping, thereby improving the user experience. Due to the structural characteristics of the ball screw, the hand-cranked screw slide 135 can withstand higher loads while reducing wear, so the hand-cranked screw slide 135 has a longer working life and reduces maintenance costs. The hand-cranked screw slide 135 is more economical in cost, especially suitable for those occasions that do not require frequent or continuous movement and have strict cost control.

[0040] Furthermore, the hand-cranked screw slide 135 also has a locking device 1353. The locking device 1353 can lock or fix the position of the slider 1351 and the base plate 131. For products of the same specification, the number of adjustments can be reduced and the stability during the glue injection and glue dispensing process can be ensured. At the same time, the locking device 1353 is flexible and light, which is convenient for precise manual adjustment or fixing, and increases the flexibility of the device.

[0041] In a feasible implementation, the clamping member 134 can be fixedly connected to the base plate 131, and the fixing member 133 can be slidably connected to the base plate 131, which can also facilitate the adjustment of the position of the loading mechanism 132 and the base plate 131. The manner in which the fixing member 133 is slidably connected to the base plate 131 can be the same or similar to the above-mentioned structure, or it can be different, which will not be repeated here.

[0042] In a feasible implementation, the glue injection and dispensing device 100 provided in the embodiment of the present application is not limited to having the bottom plate 131, and the positioning assembly 130 may be the same as the above structure, but the base 101 does not have the bottom plate 131. This will not be described in detail here.

[0043] In one possible implementation, Figure 1 As shown, the glue injection and dispensing device 100 further includes a pipeline 140 assembly, which includes six pipelines 140, one end of each pipeline 140 is connected to the conical tip of the glue nozzle 120. The loading mechanism 132 is provided with a through hole corresponding to the position of the glue injection port of the product to be injected, and the other end of each pipeline 140 is connected to the through hole of the loading mechanism 132. The pipeline 140 connects the chamber 111 in the glue box 110, the passage 1211 of the glue nozzle 120 and the glue injection port of the product to be injected, and transports the glue in the glue box 110 to the product to be injected in each loading mechanism 132.

[0044] In a feasible implementation, the glue injection and dispensing device 100 may also include more or less than 6 glue nozzles 120. Accordingly, the glue box 110 is provided with mounting holes having the same number as the glue nozzles 120. Each of the glue nozzles 120 is fixed in one of the mounting holes, and the mounting holes are evenly distributed around the axial line of the glue box 110, and the axial lines of all the mounting holes are in the same plane.

[0045] In a feasible implementation, the glue injection and dispensing device 100 further includes a centrifugal drive device. The output end of the centrifugal drive device is connected to the base 101 for driving the base 101 to rotate.

[0046] The glue injection and dispensing device 100 provided in the embodiment of the present application has a positioning component 130 evenly arranged around the glue box 110. The base 101 is driven to rotate by a centrifugal drive device, so that the glue in the glue box 110 can be evenly injected into the product to be injected in the loading mechanism 132 of the positioning component 130 through the glue nozzle 120. The production efficiency is high and the glue dispensing is uniform. The glue nozzle 120 is easy to disassemble, which is beneficial to the maintenance and use of the glue injection and dispensing device and is conducive to wide application.

[0047] Accordingly, the embodiment of the present application also provides an oxygenator preparation system. The oxygenator preparation system includes the above-mentioned glue injection and glue dispensing device. The oxygenator preparation system provided in the embodiment of the present application has all the above-mentioned advantages due to the use of the above-mentioned glue injection and glue dispensing device, which will not be repeated here.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
