Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus a repetitive description thereof will be omitted.
The words expressing the positions and directions described in the present invention are described by taking the drawings as an example, but can be changed according to the needs, and all the changes are included in the protection scope of the present invention.
Referring to fig. 1 to 4, the application discloses a piercing sealing structure, which is mainly applied to a medical related atomizing device, and can also be applied to other devices which need to pierce a package to realize smooth medium conveying.
The puncture sealing structure comprises a bottle cap 1 and a liquid medicine tube 2.
Referring to fig. 1, 2 and 8, the bottle cap 1 is generally configured to be mounted on the target bottle body 4 (the target bottle body 4 may be a medicine bottle with a liquid preparation therein), and the bottle cap 1 may be directly locked on the target bottle body 4 or may be detachably mounted on the target bottle body 4.
In some embodiments, the inner wall of the bottle cap 1 is provided with a buckle 14 (see fig. 2 or fig. 4), correspondingly, a clamping groove (see fig. 8) can be formed on the target bottle body 4, and the bottle cap 1 is simple and efficient in installation and has the function of repeated assembly through the cooperation of the buckle 14 and the clamping groove, so that the bottle cap is convenient to use with different target bottle bodies 4.
Continuing to see fig. 1 and 2, an extension 11 capable of extending into the target bottle body 4 is arranged in the bottle cap 1, so that a sufficient depth is reserved for accommodating the liquid medicine tube 2, and the target bottle body 4 and the atomizing device are conveniently assembled and installed.
In some embodiments, the bottle cap 1 and the extension portion 11 are integrally formed (for example, formed by injection molding), and the bottle cap 1 and the extension portion 11 are coaxial, so that the extension portion 11 is centered in the bottle cap 1, thereby ensuring that the liquid medicine tube 2 is centrally arranged, and improving the accuracy of the installation position.
In addition, the extension part 11 is internally provided with a cavity 111 with a sealed bottom, so that the effect of sealing the target bottle body 4 is achieved, and pollution or drug failure caused by contact of liquid preparation in the target bottle body 4 with outside air, impurities and the like is avoided.
In some embodiments, the bottom of the cavity 111 is provided with a puncture layer 12, the puncture layer 12 being connected to the extension 11 for sealing the bottom of the cavity 111. The puncture layer 12 may be disposed horizontally (see fig. 2) for ease of manufacturing. The piercing layer 12 may also be disposed obliquely (see fig. 5), and it is noted that the highest portion of the inclined surface of the obliquely disposed piercing layer 12 can be brought into contact with the spike structure 21 first, so as to obtain a better piercing effect.
For the puncture layer 12, it can be made of an aluminum-plastic composite film or a plastic sheet, etc., the thickness of the puncture layer 12 is usually controlled between 0.04mm and 0.2mm, if the thickness of the puncture layer 12 is less than 0.04mm, the structure strength is poor, and the puncture layer is easy to be damaged, so that the liquid preparation leaks; if the thickness of the puncture layer 12 is higher than 0.2mm, the puncture difficulty is increased. Preferably, the thickness of the puncture layer 12 is between 0.06mm and 0.18mm, for example, the thickness may be 0.06mm, 0.08mm, 0.1mm, 0.12mm, or 0.15mm, etc.
Referring to fig. 2 to 4, the liquid medicine tube 2 is used to pierce the bottom of the cavity 111 (i.e., the piercing layer 12) of the bottle cap 1 and deliver the liquid preparation in the target bottle 4 to the atomizing device for liquid supply. In the initial state, the medical fluid tube 2 is disposed in the extension 11 and has the ability to move downward to pierce the bottom of the cavity 111. Specifically, the bottom of the liquid medicine tube 2 is inclined and partially extends downwards to form the spike structure 21, the spike structure 21 can improve the puncturing effect and reduce the puncturing operation force, and when the liquid medicine tube 2 contacts the puncturing layer 12, the lowest point of the spike structure 21 can firstly open a notch on the puncturing layer 12, so that the puncturing is facilitated and the operation is improved.
In addition, the spike structure 21 combines with the design of the inclined bottom of the medical fluid tube 2, so that the medical fluid tube 2 does not completely damage the puncture layer 12 even when contacting the puncture layer 12 quickly. Specifically, during the puncturing process, as the spike structure 21 gradually protrudes from the extension portion 11, the puncturing layer 12 is gradually turned outwards under the guiding of the inclined surface at the bottom of the liquid medicine tube 2, so that when the highest point of the spike structure 21 is about to protrude out of the cavity 111, the puncturing layer 12 is basically turned outwards, and even if the puncturing speed of the liquid medicine tube 2 is high, no vertical shearing force is generated on the puncturing layer 12, so that the side of the puncturing layer 12 away from the spike structure 21 can be always connected with the extension portion 11, and the puncturing layer 12 is prevented from dropping to the target bottle body 4 to pollute the liquid medicine or block the conveying performance of the liquid medicine tube 2.
In some embodiments, the vertical section of the spike structure 21 is triangular, the surface of the hypotenuse is connected with the bottom of the liquid medicine tube 2, and the outer circumferential surface of the spike structure 21 is a curved surface, so that an arc-shaped cutting line matched with the puncturing layer 12 is formed, and the puncturing effect is improved. In addition, the bottom of the liquid medicine tube 2 has an inclination angle of 20-60 degrees, and if the inclination angle is smaller than 20 degrees, the bottom of the liquid medicine tube 2 has poor guiding performance, and the liquid medicine tube 2 easily causes shearing force in the vertical direction to the puncture layer 12, so that the puncture layer 12 is completely destroyed; if the inclination angle is larger than 60 °, the bottom of the medical fluid tube 2 is too sharp and long, and is easy to bend or break during puncturing, which affects the use effect. Preferably, the inclination angle of the bottom of the medical fluid tube 2 may be 30 °, 40 °, 45 °, 50 °, etc.
Referring to fig. 2 and 4, the outer circumference of the medical fluid tube 2 is provided with a sealing member 3, and the sealing member 3 may be a sealing ring, a sealing sleeve, or the like, and may be made of a rubber material, for example, medical grade fluororubber, so as to meet the sanitary and safety requirements of the medical industry, and can seal stably and reliably. When the spike structure 21 pierces the bottom of the cavity 111, the liquid medicine tube 2 is exposed from the inside of the extension portion 11 and is communicated with the inside of the target bottle body 4, and meanwhile, the sealing member 3 seals the gap between the cavity 111 and the liquid medicine tube 2, so that the liquid preparation in the target bottle body 4 is prevented from contacting with the outside air, impurities and the like, and pollution or drug property failure is avoided.
It should be noted that, when the medical fluid tube 2 is located in the extension portion 11 (in the initial state), the sealing member 3 may or may not seal the gap between the cavity 111 and the medical fluid tube 2 due to the bottom sealing of the cavity 111, and when the medical fluid tube 2 pierces the bottom of the cavity 111 (in the pierced state), the sealing member 3 must seal the gap between the cavity 111 and the medical fluid tube 2, so as to ensure the tightness between the extension portion 11 and the medical fluid tube 2.
In a preferred embodiment, as shown in fig. 1 to 5, a connecting strip 13 is disposed between the extending portion 11 and a side of the puncture layer 12 away from the spike structure 21, and the connecting strip 13 can also be fixed on the extending portion 11 to prevent the puncture layer 12 from falling off for standby.
In a specific embodiment, the piercing layer 12 has a structure with a thick middle part and a thin edge, which is beneficial to integrally forming the piercing layer 12 and the extension part 11 on one hand and reduces the difficulty of the forming process; on the other hand, the edge of the puncture layer 12 is most easily separated from the extension 11 during the puncturing, and the puncture layer 12 itself is not easily deformed to affect the puncturing effect. Illustratively, the middle of the puncture layer 12 is of a domed hemispherical configuration and the edges are of a flat rounded configuration. The puncture layer 12 with the shape can be better matched with the inclined surface at the bottom of the liquid medicine tube 2 through the hemispherical structure with the arched middle part, so that the eversion effect of the puncture layer 12 is improved.
Referring to fig. 1 to 4, in a preferred embodiment, the cavity 111 has a horn-shaped structure, the cavity 111 includes a straight opening section 1111 and a necking section 1112 sequentially disposed from top to bottom, and the straight opening section 1111 and the necking section 1112 are smoothly transited.
In the initial state, the spike structure 21 is accommodated in the necking section 1112, and the sealing element 3 is in clearance fit with the straight opening section 1111, so that the bottom of the cavity 111 is not pierced by the liquid medicine tube 2, and the sealing element 3 is designed to be in clearance fit with the straight opening section 1111, so that the resistance in the downward moving process of the liquid medicine tube 2 can be effectively reduced, and the piercing operation is facilitated.
In the puncturing state, the spike structure 21 extends out of the necking section 1112, and the liquid medicine tube 2 drives the sealing member 3 to move downwards until the sealing member is in sealing fit with the necking section 1112, so that the liquid preparation in the target bottle body 4 is prevented from being contacted with the outside air, impurities and the like, and pollution or drug property failure is avoided. In addition, when the sealing element 3 is tightly attached to the necking section 1112 for sealing, the sealing element 3 can reversely squeeze the liquid medicine tube 2 for fixing, so that the position of the liquid medicine tube 2 is stable and does not deviate or shake, and the reliability of transfusion of the liquid medicine tube 2 is ensured.
Referring to fig. 2, 4 and 6, in some embodiments, the sealing member 3 has a substantially truncated cone shape with a large upper part and a small lower part, so as to perform surface sealing fit with the necking section 1112, and ensure the fixing effect on the medical fluid tube 2.
Further, the bottom and the top of the sealing member 3 are provided with a first convex ring portion 31 and a second convex ring portion 32, respectively, and the vertical cross sections of the first convex ring portion 31 and the second convex ring portion 32 are arc-shaped. The protruding dimension of the first convex ring portion 31 is smaller than that of the second convex ring portion 32, so that the first convex ring portion 31 and the second convex ring portion 32 can be matched with the necking section 1112 in a sealing manner, two line seals with tighter bonding are formed, and the sealing effect of the liquid medicine tube 2 and the cavity 111 is improved.
Referring to fig. 6 and 7, in some embodiments, the outer circumference of the medical fluid tube 2 is provided with a limiting groove 22, and the sealing member 3 is partially embedded in the limiting groove 22; and/or the periphery of the liquid medicine tube 2 is provided with a limit rib 23, and the seal member 3 is partially sleeved on the limit rib 23.
The limiting groove 22 and the limiting rib 23 can increase the resistance applied to the axial movement of the sealing element 3, improve the connection strength of the sealing element 3 and the liquid medicine tube 2, and avoid the influence of the loosening of the sealing element 3 and the tightness of the necking section 1112. Illustratively, the limiting groove 22 may be a dovetail groove, and at least the first convex ring portion 31 and the second convex ring portion 32 are partially embedded in the dovetail groove, thereby further enhancing the connection of the sealing member 3 with the medical fluid tube 2. The limiting rib 23 may be an annular rib, and the annular rib is inclined downwards to form an umbrella-like structure so as to form a blocking design, and at least the first convex ring portion 31 and the second convex ring portion 32 are partially sleeved on the annular rib, so that the connection between the sealing element 3 and the liquid medicine tube 2 can be enhanced, and a good anti-drop effect is achieved.
Referring to fig. 8, the application also discloses an atomization device, which comprises the puncture sealing structure of any one of the above-mentioned claims, has the advantages of convenient puncture and smooth liquid supply, and can effectively avoid the contact of the liquid preparation in the bottle with the outside air, impurities and the like, thereby causing pollution or drug property failure.
