Technical Field

[0001] The utility model relates to the technical field of screw caps for prefilled catheter flushers, in particular to a screw cap mechanism for prefilled catheter flushers. Background Art

[0002] Prefilled catheter flusher is a new type of tube-locking liquid that can replace traditional saline and other tube-locking liquids. This new type of tube-locking liquid has a wide range of applications, is easy to operate, has few limitations, and has little effect on the patient's condition and physiological indicators. One prefilled catheter flusher can complete some drug preparations before infusion, reduce the consumption of heavy materials, and is convenient for storage. It can reduce the chance of contamination, reduce the risk of infection, is highly safe, avoid needlestick injuries to medical staff, and also reduce operation time.

[0003] During its production process, the entire assembly line is required for filling. The whole machine is generally composed of a feeding mechanism, static elimination, siliconized components, a plugging mechanism, a filling mechanism, a capping mechanism, a rejecting mechanism, etc. However, the capping mechanism of the traditional technology is generally composed of a single motor, which drives multiple capping mechanisms to cap at the same time through gear transmission. For example, the application number is "CN201920832774.9", a prefilled catheter flusher capping mechanism, the prefilled catheter flusher capping mechanism includes: a capping unit, a capping unit, and a capping unit; the capping assembly has two "7"-shaped mechanism supports, the mechanism support has a vertical seat and a long horizontal seat integrally extending from the top of the vertical seat and perpendicular to the vertical seat, and an I-shaped slide rail is fixed on the upper surface of the long horizontal seat; the lifting assembly has a capping upper platform, and the two ends of the capping upper platform are vertically mounted on the long horizontal seat and move along the I-shaped slide rail. The utility model directly eliminates the structure of the blocking cylinder support and sets the mechanism support into a "7"-shaped support. In this way, by changing the inserted upper platform shaft into a slide rail form, the push-pull resistance of the horizontal cylinder is greatly reduced, the upper platform of the screw cap is smoothly moved horizontally, the work efficiency is improved, and the equipment structure is simplified.

[0004] The disadvantage of this is that each screw cap mechanism works synchronously, but the initial angles of the screw caps are different, which can easily lead to insufficient connection between some protective caps and prefilled catheter flushers, and too tight connection between some protective caps and prefilled catheter flushers, and even damage to the threaded connection.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] The screw capping mechanism of traditional technology is generally driven by a single motor through gear transmission to simultaneously drive multiple screw capping mechanisms to screw the caps. The disadvantage of this is that each screw capping mechanism works synchronously, and the initial angles of the screw caps are different, which may easily lead to insufficient connection between some protective caps and prefilled catheter flushers, and too tight connection between some protective caps and prefilled catheter flushers, and even damage to the threaded connection.

[0021] In view of this, the utility model provides a cap screwing mechanism for a prefilled catheter flusher. Through the cooperation among the driving member, the cap driving device and the bracket, not only the cap is automatically installed inside the cap positioning member from the inside of the cap positioning template, which is beneficial to the subsequent cap screwing action, but also the cap is accurately moved to the bottom of the prefilled catheter flusher. In addition, each cap driving device works independently, so the cap screwing action can be controlled by the tightness of the cap. The tightness of each cap is consistent, or can be adjusted individually according to needs, which is beneficial to actual production.

[0022] Depend on Figure 1 It can be seen that a prefilled catheter flusher cap screwing mechanism in this case includes a base frame 1, and a bracket 8 is installed inside the base frame 1. The prefilled catheter flusher cap screwing mechanism also includes: a protective cap positioning member 9, which is provided in plurality and installed above the bracket 8; a protective cap driving device 6, which is installed between the bracket 8 and the protective cap positioning member 9; two driving members 4 are provided and installed between the bracket 8 and the base frame 1; a protective cap positioning template 7, which is provided corresponding to the protective cap positioning member 9; wherein the bracket 8 can be moved laterally and longitudinally through the inside of the driving member 4, so that the lateral and longitudinal positions of the protective cap positioning member 9 can be adjusted through the protective cap driving device 6, wherein the driving member 4 can be a cylinder, a hydraulic cylinder or an electric push rod, etc. Of course, it can also be any device that can realize this embodiment and meet the working requirements of this embodiment, and can be selected and used according to actual needs.

[0023] In the specific implementation process, it is worth pointing out that the base frame 1 is used to support the cap screwing mechanism of the prefilled catheter flusher and is installed at the corresponding position of the prefilled catheter flusher filling machine, specifically between the filling mechanism and the rejection mechanism. A longitudinal and transverse motion pair is provided between the bracket 8 and the base frame 1. The purpose of the transverse movement is to move the protective cap inside the protective cap positioning member 9 to the bottom of the prefilled catheter flusher. The purpose of the longitudinal movement is to facilitate the lifting of the protective cap positioning member 9 to insert the protective cap inside the protective cap positioning template 7 into the interior of the protective cap positioning member 9 and move it downward, so as to facilitate the transverse movement of the protective cap. After moving horizontally to the bottom of the prefilled catheter flusher, it rises again and is aligned with the prefilled catheter flusher, which is convenient for the protective cap driving device 6 to screw the cap. It is worth mentioning that during the screwing process, the driving member 4 rises synchronously. After the screwing, the protective cap positioning member 9 returns to its original position under the action of the driving member 4, that is, it moves to the bottom of the protective cap positioning template 7, and continues to move the next group of protective caps. Multiple protective cap driving devices 6 are provided, that is, a protective cap driving device 6 is separately provided under each protective cap positioning member 9, and multiple protective cap driving devices 6 are independently controlled and driven, so that the tightness of the screwing of each protective cap can be controlled.

[0024] In one practicable manner, a protective cap feeder 2 is provided on one side of the protective cap positioning template 7 .

[0025] During the specific implementation process, it is worth pointing out that the purpose of the protective cap feeder 2 is to feed the protective caps into the interior of the protective cap positioning template 7. The protective cap feeder 2 can use a vibrating disc feeding device. The specific model is not limited, and it only needs to meet the technical solution recorded in this embodiment.

[0026] In an practicable manner, the top of the bracket 8 is fixedly connected to the top frame 3 via a connecting piece, and the top frame 3 is arranged above the protective cap positioning template 7.

[0027] In the specific implementation process, it is worth pointing out that the purpose of the top frame 3 is to facilitate the installation of other necessary structures.

[0028] In an practicable manner, a detection photoelectric device 5 corresponding to the protective cap positioning template 7 is disposed at the bottom of the top frame 3 .

[0029] In the specific implementation process, it is worth pointing out that the specific model of the detection photoelectric 5 is not limited, and its purpose is to detect whether there is a protective cap on the protective cap positioning piece 9. If there is a protective cap, the protective cap positioning piece 9 of the workstation stops adding the protective cap to the protective cap positioning piece 9, wherein the top of the protective cap positioning piece 9 is in a groove shape, and the inner wall is provided with a protrusion, and the protective cap is inserted therein, and the cap rotating action can be realized by rotating the protective cap positioning piece 9.

[0030] In one practicable manner, see Figure 2The protective cap driving device 6 includes: a cap head 61, installed at the bottom of the protective cap positioning member 9; a reducer 62, fixedly connected to the bottom of the cap head 61 and fixedly connected to the inner wall of the bracket 8; a servo motor 63, installed at the input end of the reducer 62; wherein, the cap head 61 directly drives the protective cap positioning member 9, and the servo motor 63 drives the cap head 61 through the reducer 62 to rotate the protective cap positioning member 9.

[0031] In the specific implementation process, it is worth pointing out that according to the number of protective cap positioning parts 9, a corresponding number of cap heads 61 are set, and each cap head 61 is driven to rotate independently through the cooperation of the reducer 62 and the servo motor 63, so that the tightness of the screw cap of each protective cap can be controlled separately.

[0032] It is understandable that the specific models of the reducer 62 and the servo motor 63 are not limited, as long as they meet the usage requirements.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0034] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
