AI Technical Summary
The existing pre-filled rinsers lack positioning structure during the label pasting process, which leads to the inclination of the label and affects product quality; the edges of the label are prone to negative phenomena such as lifting and degumming, and the ink in the printing batch area is also prone to fading, and the font is burped, which affects the effective information reading.
A prefilled conduit flusher with a matte structure is designed, including a first matte surface and a second matte surface. The first matte surface facilitates label positioning, prevents label skew, and increases label stickiness, prevents lifting and degumming; the second matte surface increases the ink stability and firmness of the printing batch area, preventing fading and font burrs.
Through the matte structure, the label can be accurately positioned during the pasting process, avoiding skew and curling, and enhancing stickiness. At the same time, the matte surface improves the ink stability of the printing batch area, prevents fading and burrs, and ensures clarity and readability of information.

[0023] 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 protection scope of the utility model.
[0024] Embodiment 1 of the present utility model, as Figure 1 and Figure 2 As shown, the prefilled catheter flusher includes a flusher body 1 and a Luer cap 2 arranged at the front end of the flusher body 1, a push rod 3 with a silicone cap is movably installed in the flusher body 1, a first frosted surface 11 is arranged on the outer surface of the flusher body 1, the length direction of the first frosted surface 11 is arranged parallel to the central axis of the flusher body 1, a partition table 111 is arranged at the center of the first frosted surface 11, and the partition table 111 is integrally formed with the flusher body 1, a printing batch number area is arranged on the side of the flusher body 1 away from the first frosted surface 11, and a second frosted surface 12 is arranged on the surface of the flusher body 1 in the printing batch number area, the first frosted surface 11 is convenient for label positioning to prevent the label from being skewed, and the frosted texture increases the viscosity of the label to prevent the label from curling up, degumming and other defects, and the second frosted surface 12 can increase the ink stability and firmness in the printing batch number area to prevent fading, printing font roughness and other defects.
[0025] The cross-sectional shape of the partition table 111 is a trapezoid, and the first frosted surfaces 11 are symmetrically distributed on both sides of the partition table 111. The partition table 111 is located on the parting surface of the rinser body 1 to prevent the contour of the parting surface of the rinser body 1 from affecting the appearance.
[0026] A positioning rib 112 is extended from the edge of the partition table 111 toward the first frosted surface 11. The positioning rib 112 is perpendicular to the central axis of the flushing device body 1, and the positioning rib 112 is distributed along the circumference of the flushing device body 1. The height of the positioning rib 112 is higher than the first frosted surface 11, which provides positioning during the labeling process to ensure accurate label positioning. Regardless of the width of the label, the label can be accurately positioned by aligning the adjacent two sides of the label with the partition table 111 and the positioning rib 112 on one side.
[0027] An auxiliary pasting mechanism is provided on the partition table 111, and the auxiliary pasting mechanism includes a flat hole 114 opened on the partition table 111 and penetrating the partition table 111. The bottom surface of the flat hole 114 is higher than the first frosted surface 11. A fixed membrane 113 is placed in the flat hole 114. The surface of the fixed membrane 113 close to the first frosted surface 11 is provided with adhesive. After the label is pasted, the staff will pass the fixed membrane 113 with the adhesive side facing down through the flat hole 114 to fix the edge of the label on the first frosted surface 11 to avoid the edge of the label from curling up due to long-term storage.
[0028] The frosted structure of the first frosted surface 11 and the second frosted surface 12 is a conical dome structure, a pyramidal dome structure, a conical flat-top structure, a pyramidal flat-top structure or a combination of several thereof. The frosted surface can be integrally formed with the flusher body 1 through a mold, or can be formed through sandblasting, hot stamping and other processes after the flusher body 1 is formed. Compared with the dome structure, the flat-top structure has a larger contact area with the label and has a stronger adhesion.
[0029] The second frosted surface 12 is a nano-level treated frosted surface. The distribution density of the frosted structure of the second frosted surface 12 is greater than that of the first frosted surface 11. The nano-level treated frosted surface is not obvious from the appearance, but can increase the ink stability and firmness in the printed batch number area, prevent fading, rough edges of printed fonts and other defects, and facilitate staff to extract effective production information. The second frosted surface 12 also solves the problem that the printed batch number of the prefilled catheter flusher currently in clinical practice naturally ages and falls off, and cannot be traced back to the batch number of the medical device. At the same time, it solves the problem that if the printed ink fades, the faded printing ink will cross-contaminate other medical supplies or equipment, causing potential cross-contamination and infection in the hospital.
[0030] Embodiment 2 of the present utility model, as Figure 3 As shown, the difference from the first embodiment is that the auxiliary pasting mechanism includes a fixed film 113 arranged on both sides of the partition table 111, one end of the fixed film 113 is fixedly connected to the partition table 111, and an adhesive is arranged on the surface of the fixed film 113 close to the first frosted surface 11. The fixed film 113 is directly fixed on both sides of the partition table 111. After the label is pasted, the fixed film is directly pressed down to fix the edge of the label, which is more convenient to operate than the first embodiment.
[0031] The working principle of this embodiment is as follows: the staff puts one end of the label against one end of the partition table, aligns the side of the label with the positioning retaining edge, and then presses down to make the adhesive surface stick to the first frosted surface. Depending on the length of the label, choose to stick it around the flusher body or on both sides of the partition table. After the label is pasted, inkjet the production batch number on the second frosted surface.
[0032] Several points that need to be explained are: First, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two elements, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.
[0033] The above examples are merely illustrative of the present utility model and do not constitute a limitation on the protection scope of the present utility model. All designs that are identical or similar to the present utility model fall within the protection scope of the present utility model.
