Description

Technical Field

[0001] The present invention relates to the technical field of packaging header bags, in particular to a packaging header bag for medical devices. Background Art

[0002] Common products include pure film packaging bags: pure film bags are made of general high-molecular polyethylene. Due to the anisotactic nature of its molecular structure, polyethylene has average puncture resistance and tear strength, and extremely poor air permeability, which is not conducive to the penetration of sterilization factors. It poses a great challenge to the effectiveness and resolution of EO sterilization. Sterilization using such packaging bags often has poor sterilization effects and large toxic residues. In addition, existing packaging header bags are easily torn during later use due to the heat-sealing operation during packaging, and therefore do not meet the requirements of high tear strength and puncture resistance. Summary of the Invention

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0004] In view of the above-mentioned problems existing in the existing header bag for medical device packaging, the present invention is proposed.

[0005] Therefore, an object of the present invention is to provide a header bag for packaging medical devices.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a medical device packaging header bag, comprising a first packaging layer, a second packaging layer arranged on the first packaging layer, a sealing component arranged between the first packaging layer and the second packaging layer; and a connecting film layer arranged on the second packaging layer.

[0007] As a preferred solution of the medical device packaging header bag described in the present invention, the sealing component includes a first pressing edge arranged on the first packaging layer, a second pressing edge arranged on the second packaging layer, and a texture arranged on the first pressing edge, and the second pressing edge is provided with a matching texture that matches the texture.

[0008] As a preferred solution of the medical device packaging header bag of the present invention, the matching lines are evenly and equidistantly arranged on the second pressing edge, and a concave groove is formed between the matching lines. The lines include a plurality of mutually spliced ​​pressed monomers arranged on the first pressing edge. The pressing unit includes a texture ring arranged on the first pressing edge and a clamping edge arranged on the texture ring, and a matching bayonet matched with the clamping edge is provided on the matching texture.

[0009] As a preferred solution of the medical device packaging header bag described in the present invention, wherein: the card edge includes a connecting piece connected to the textured ring and a bending portion arranged on the connecting piece, several card edges on each of the textured rings are not connected to each other, the bending portion includes a first arc surface and a second arc surface, the curvature of the first arc surface is smaller than the curvature of the second arc surface, a matching arc groove that cooperates with the bending portion is provided on the recessed groove, and the card edge also includes a bent hook that is arranged at the front end of the bending portion and cooperates with the bayonet.

[0010] As a preferred solution of the medical device packaging header bag of the present invention, a fold is provided at the intersection of the first arc surface and the second arc surface, and an adhesive layer is provided between the connecting piece and the matching lines. An extension portion extends from the side wall of the mating pattern, the concavity of the fold matches the degree of arc-shaped convexity of the front end of the extension portion, and the extension portion includes a crown convex portion connected to the mating pattern and a conical portion connected to the crown convex portion, and the left and right side lines of the cross-section of the conical portion and the crown convex portion are symmetrical.

[0011] As a preferred solution of the medical device packaging top bag described in the present invention, wherein: a sandwich area is reserved on the side of the second packaging layer near the connecting film layer, the sandwich area is used to dock with the connecting film layer, a cushioning layer is arranged in the sandwich area, inner closings are arranged on both sides of the sandwich area, an expansion cavity is arranged in the inner closing, filling material is arranged in the expansion cavity, and the material of the expansion cavity is a flexible material.

[0012] As a preferred solution of the medical device packaging header bag described in the present invention, the filling material includes a solid filler and silver nanoparticles evenly distributed in the solid filler, the expansion cavity is set to a hard material on the side close to the inner closing opening, and the expansion cavity bulges outward away from the side of the inner closing opening.

[0013] As a preferred solution of the header bag for medical device packaging of the present invention, a pressed edge is provided at the side edge of the first packaging layer.

[0014] The beneficial effects of the present invention are as follows: during pressing, the bent hook first contacts the mating arc groove, and then under the arc action of the mating arc groove, the bent hook bends, and extends upward after bending. As the texture ring continues to press down, the bent portion enters the mating arc groove.

[0015] A fold is provided at the junction of the first arc surface and the second arc surface, and an extension is extended on the side wall of the matching pattern. At this time, as the pattern ring is pressed downward, the pattern ring will also press the matching pattern downward. The downward pressure of the matching pattern will drive the extension on the matching pattern to be pressed downward, thereby pressing the position of the fold, thereby pressing the card edge into a "folded" state. At this time, the bent hook can cooperate with the matching bayonet to achieve locking and sealing.

[0016] Furthermore, after the first packaging layer and the second packaging layer are pressed together, the first packaging layer and the second packaging layer cannot be easily torn apart due to the provision of the sealing component. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0030] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included. Example

[0031] Reference Figure 1-7 The present invention discloses a medical device packaging header bag, including a first packaging layer 100. The first packaging layer 100 is relatively light and thin as a whole. A second packaging layer 101 is arranged on the first packaging layer 100. The first packaging layer 100 and the second packaging layer 101 are made of the same material, and the outer layers are both coated with an aluminum film layer. The first packaging layer 100 and the second packaging layer 101 include an outer layer, an intermediate layer and an inner layer. The melting point of the inner layer is 100-105°C, the melting point of the intermediate layer is 105-110°C, and the melting point of the outer layer is 110-120°C.

[0032] A sealing component is provided between the first packaging layer 100 and the second packaging layer 101, which is mainly used for sealing the edge positions of the first packaging layer 100 and the second packaging layer 101, and an opening is left on one side of the first packaging layer 100 and the second packaging layer 101, and a connecting film layer 102 is provided on the second packaging layer 101.

[0033] The first packaging layer 100, the second packaging layer 101 and the connecting film layer 102 constitute the structure of the entire header bag, and the connecting film layer 102 mainly has a three-layer structure, namely an outer layer of DuPont Tyvek, a middle layer made of LDPE and LLDPE, and an inner layer made of LDPE and 1-butene. The middle layer and the inner layer are composited to form a PE connecting film. Finally, the PE connecting film and DuPont Tyvek are heat-sealed at 100°C to form a finished film. The finished film is sealed at the bag mouth of the header bag. Preferably, the mass fractions of LDPE and LLDPE in the middle layer are 20-40% and 50-80% respectively. Preferably, the mass fractions of LDPE and 1-butene in the inner layer are 30-50% and 40-70% respectively.

[0034] Furthermore, in this embodiment, the sealing component includes a first pressing edge 201 provided on the first packaging layer 100, the first pressing edge 201 extending outward from three side positions of the first packaging layer 100, wherein the width of the first pressing edge 201 located on the two long sides of the first packaging layer 100 is smaller than the width located on the short side of the first packaging layer 100, and a second pressing edge 202 is provided on the second packaging layer 101, the second pressing edge 202 corresponds to the first pressing edge 201, and the first pressing edge 201 and the second pressing edge 202 are aligned with each other. A gathering edge is provided at the end side edge position of the edge 202. When the first pressing edge 201 and the second pressing edge 202 correspond to each other, the gathering edge on the first pressing edge 201 and the gathering edge on the second pressing edge 202 are close to each other. Because the cross-section of the gathering edge is a hook shape with a certain arc, when the first pressing edge 201 and the second pressing edge 202 are fitted together, the hook-shaped edges of the first pressing edge 201 and the second pressing edge 202 will abut against each other and bend in corresponding directions to each other, thereby playing the role of alignment and facilitating subsequent fitting.

[0035] Furthermore, a plurality of lines 203 are provided on the first pressing edge 201, and matching lines 204 that match the lines 203 are provided on the second pressing edge 202. The arrangement of the lines 203 and the matching lines 204 facilitates the clamping when the first packaging layer 100 and the second packaging layer 101 are pressed together, and because of the arrangement of the lines 203 and the matching lines 204, a certain auxiliary effect can be played in the pressing of the first packaging layer 100 and the second packaging layer 101.

[0036] Furthermore, the mating lines 204 are evenly and equidistantly arranged on the second pressing edge 202. The mating lines 204 are shaped like rectangular blocks and bulge upward, with the upper surface forming a certain arc. In order to increase the surface area during subsequent adhesion, a number of fine indentations are opened on the upper surface, and recessed grooves 205 are formed between the mating lines 204 and the mating lines 204. When observed from the front of the second pressing edge 202, the recessed grooves 205 are opened around each mating line 204, and several recessed grooves 205 are connected to each other.

[0037] Preferably, when observed from the front of the second pressure edge 202, the recessed groove 205 can be decomposed into a number of first inclined grooves and a number of second inclined grooves, the first inclined grooves being inclined from the upper left side of the second pressure edge 202 to the lower right side of the second pressure edge 202, and the second inclined grooves being inclined from the upper right side of the second pressure edge 202 to the lower left side of the second pressure edge 202, and the first inclined grooves and the second inclined grooves being staggered with each other to form a rectangular shape of the recessed groove 205, and the corner positions where a rectangle cannot be formed are filled with solid objects.

[0038] Moreover, the angle between the first inclined groove and the second inclined groove is between 89° and 91°, preferably 90° in this embodiment, so that the formed recessed groove 205 is in a square shape.

[0039] Furthermore, in this embodiment, the pattern 203 includes a plurality of mutually spliced ​​pressing units 206 arranged on the first pressing edge 201, and the shape of each pressing unit 206 also corresponds to the shape of the recessed groove 205, so that the edge of the pressing unit 206 can be inserted into the recessed groove 205, and then matched with the matching pattern 204 to achieve matching.

[0040] Preferably, in this embodiment, the pressing unit 206 includes a groove 203 ring provided on the first pressing edge 201 and a card edge 206b provided on the groove 203 ring. The groove 203 rings are arranged close to each other, and the card edges 206b between the groove 203 rings are close to each other but not in contact. The two card edges 206b correspond to a concave groove 205, and the lateral width of the concave groove 205 is greater than the width between the two card edges 206b. The card edge 206b cooperates with the mating bayonet 206c, and the mating bayonet 206c is opened on the four sides of the mating pattern 204, and the position of the mating bayonet 206c is higher. The position height of the mating bayonet 206c is set at a position away from the recessed groove 205. When the card edge 206b is pressed down, the card edge 206b is obstructed and guided by the curvature of the recessed groove 205 and the edge position of the mating pattern 204, and the card edge 206b flips up, thereby being stuck in the mating bayonet 206c.

[0041] In this embodiment, the clamping edge 206b includes a connecting piece 206d connected to the groove 203 ring and a bending portion 206e arranged on the connecting piece 206d. The several clamping edges 206b on each groove 203 ring are not connected to each other, that is, the connecting pieces 206d on each groove 203 ring are not interconnected, and thus each connecting piece 206d can be bent individually. This setting ensures that when each groove 203 ring is clamped, if one connecting piece 206d occasionally fails to clamp or is misaligned, the remaining connecting pieces 206d can still be clamped individually.

[0042] Moreover, each connecting piece 206d is not connected to each other, thereby forming a certain gap. This gap provides space for the connecting piece 206d to deform and expand after being pressed together, and a certain flow channel is formed between each gap. The operator can apply a certain amount of adhesive or other impedance agent during pressing. The impedance agent increases the barrier ability to oxygen, moisture and microorganisms, thereby extending the shelf life of the product.

[0043] Furthermore, in this embodiment, the bending portion 206e includes a first arc surface 207 and a second arc surface 208. The curvature of the first arc surface 207 is smaller than that of the second arc surface 208. The first arc surface 207 is arranged at an end position closer to the clamping edge 206b, and the second arc surface 208 is arranged at a rear position. A mating arc groove 209 that cooperates with the bending portion 206e is provided on the recessed groove 205. The clamping edge 206b also includes a bending hook 206f arranged at the front end of the bending portion 206e and mating with the mating slot 206c.

[0044] Preferably, a pressing edge 308 is provided on the side of the first packaging layer 100 , and the pressing edge 308 can assist in positioning the bonding of the connecting film layer 102 .

[0045] Preferably, the radius of the first arc surface 207 is preferably 0.0.25 mm, and the radius of the second arc surface 208 is preferably 0.03 mm.

[0046] Operation process: During pressing, the bending hook 206f first contacts the mating arc groove 209, and then under the arc action of the mating arc groove 209, the bending hook 206f bends, and extends upward after bending. As the pattern 203 ring continues to press down, the bending portion 206e enters the mating arc groove 209. Because the bending portion 206e is also in contact with the mating arc groove 209, and because of the cooperation between the arc surfaces, the first arc surface 207 of the bending portion 206e is bent.

[0047] A fold 300 is provided at the junction of the first arc surface 207 and the second arc surface 208, and an extension 302 extends on the side wall of the matching pattern 204. At this time, as the pattern 203 ring is pressed downward, the pattern 203 ring will also press the matching pattern 204 downward. The downward pressure of the matching pattern 204 will drive the extension 302 on the matching pattern 204 to be pressed downward, thereby pressing the position of the fold 300, thereby pressing the card edge 206b into a "folded" state. At this time, the bent hook 206f can cooperate with the matching bayonet 206c, thereby achieving locking and sealing.

[0048] Furthermore, after the first packaging layer 100 and the second packaging layer 101 are pressed together, the first packaging layer 100 and the second packaging layer 101 will not be easily torn apart due to the provision of the sealing component. Example

[0049] Reference Figure 8 This embodiment is different from the previous embodiment in that: further, an adhesive layer 301 is provided between the connecting piece 206d and the matching pattern 204, and the adhesive layer 301 can play a certain adhesive role.

[0050] In this embodiment, the degree of concavity of the fold 300 matches the degree of arc-shaped convexity at the front end of the extension 302. In this embodiment, the extension 302 includes a crown convex portion 302a connected to the mating pattern 204 and a conical portion 302b connected to the crown convex portion 302a. The left and right side lines of the cross-sections of the conical portion 302b and the crown convex portion 302a are symmetrical.

[0051] Preferably, when observing the cross-section of the extension 302 from the front, the arcs on either side of the crown convex portion 302a are formed by drawing a circle with its center at the center of gravity of the crown convex portion 302a and its radius equal to the length from the center of gravity to the connection between the extension 302 and the mating pattern 204. The arcs on either side of the tapered portion 302b are formed by drawing a circle with its radius equal to half the line connecting the center of gravity of the crown convex portion 302a and the center of gravity of the tapered portion 302b and its center at the center of gravity of the tapered portion 302b. The arcs of the crown convex portion 302a and the tapered portion 302b are connected by a tangent arc, thereby forming the arcs on either side of the crown convex portion 302a and the tapered portion 302b.

[0052] The front end of the tapered portion 302 b is configured to be tapered so as to press against the fold 300 . Example

[0053] Reference Figure 9 and Figure 10 This embodiment is different from the previous embodiment in that an interlayer area 303 is reserved on the side of the second packaging layer 101 near the connecting film layer 102, and the interlayer area 303 is used to connect with the connecting film layer 102. A padding layer 304 is provided in the interlayer area 303, and the padding layer 304 is used for adhesion.

[0054] Furthermore, inner openings 305 are provided on both sides of the sandwich region 303 , and the cross-section of the inner openings 305 is triangular, so that the cross-section of the entire sandwich region 303 forms a trapezoidal shape.

[0055] Furthermore, an expansion cavity 306 is provided in the inner opening 305 , and a filling material 307 is provided in the expansion cavity 306 . The material of the expansion cavity 306 is a flexible material.

[0056] The filling material includes a solid filler and silver nanoparticles uniformly distributed in the solid filler. The good thermal conductivity of the silver nanoparticles allows the low-boiling-point acetone solvent to quickly reach its boiling point, and the liquid boils and transforms into gas, which is used to deform the inner opening 305.

[0057] A number of phase-change droplets are distributed within the solid filler. Acetone is used as the phase-change droplet solvent. In the specific design of the phase-change droplets, a low-boiling-point organic solvent is used. Acetone can be used as the low-boiling-point organic solvent. At a low temperature of 40 degrees Celsius, the flexible deformable body deforms, thereby outwardly contacting the composite substrate layer, causing the inner opening 305 to deform to a certain shape. The side of the expansion cavity 306 proximal to the inner opening 305 is constructed of a hard material, while the side of the expansion cavity 306 distal to the inner opening 305 protrudes outward. Consequently, when the first packaging layer 100 and the second packaging layer 101 are pressed together, the high temperature causes the droplets in the expansion cavity 306 to undergo a gas-liquid phase transition, causing the expansion cavity 306 to expand and deform away from the inner opening 305, thereby compressing the connecting film layer 102. Example

[0058] This is an embodiment of the present invention. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.

[0059] Select an existing environment, use the complete setting data based on our invention and technical solution, cooperate with the corresponding software, configure pressure sensors, force sensors, temperature sensors and other related sensors, microprocessors, wireless communication modules and central control consoles.

[0060] Conduct a pulling experiment: Use a pulling force of the same intensity to tear each sealing component 102 to cause it to deform, and use a high-speed camera to record the deformation states of the three sealing components 102 respectively. The recording position of the camera is set on the side of the sealing component to better record the deformation state of the sealing component.

[0061] A micro pressure sensor is provided at the lower end of each sealing component.

[0062] In this embodiment, the arrangement of the micro pressure sensors is similar to that on a quarter-circular surface, and each sealing component corresponds to four micro pressure sensors, thereby being able to better monitor the surface pressure when the sealing component is torn.

[0063] At the same time, the data of each micro pressure sensor is recorded and integrated after recording, and the change of pressure over time is observed.

[0064] Then, the five sealing components are pulled separately to tear the first packaging layer 100 and the second packaging layer 101 apart. Then, the values ​​of the micro pressure sensors at the time of tearing and the time when all the micro pressure sensors receive the pressure are recorded. As the size of the sealing component gradually increases, the required force will gradually increase. However, when it increases to the size of the sealing component 3, the required force is the largest. Therefore, the setting size at this time is the size that can achieve the best sealing and tearing resistance effect.
