Description

Technical Field

[0001] This utility model relates to the field of sterilization packaging bags, and particularly to sterilization packaging bags for surgical instruments. Background Technology

[0002] Sterilization bags are widely used in the sterilization of surgical instruments. The specific usage is as follows: Place the surgical instruments to be sterilized into the sterilization bag. Note that the sterilization bag should only be filled to 3 / 4 of its volume to ensure proper air removal and sterilizing agent penetration. If a self-sealing sterilization bag is selected, remove the protective strip and fold the adhesive strip (at the dotted line) onto the bag to seal it. Confirm that the seal is intact with no open areas. Apply pressure from the center of the adhesive strip towards the edge. Repeat this process once more for enhanced safety.

[0003] However, in actual use, some surgical instruments have sharp or pointed parts, which often cause operators to accidentally puncture the sterilization packaging bags during instrument packing. To prevent this problem, either operator training needs to be strengthened or the sterilization packaging bags need to be improved. Existing sterilization packaging bags also have some structures designed to prevent punctures, but these designs are relatively complex and increase bag manufacturing costs, production processes, and the need for specialized equipment. Alternatively, some existing puncture-proof structures do not provide protection when the surgical instrument is placed in the bag, but only after the instrument is properly packed.

[0004] Therefore, there is an urgent need to design a sterilization packaging bag that can not only prevent surgical instruments from puncturing the bag, but also control the preparation process and cost of the sterilization packaging bag. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization packaging bag for surgical instruments. This bag effectively prevents instruments from being punctured during packaging and sterilization transport. Furthermore, it facilitates medical staff in establishing physical connections based on the surgical instrument list during surgical preparation, enabling inventory checks and preventing omissions. The bag-making process is simple, requires no additional specialized equipment, and achieves ideal cost control.

[0006] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a bag body; the bag body includes a dialysis layer and a transparent layer; the dialysis layer is dialysis paper; the transparent layer is a transparent composite film; the dialysis layer and the transparent layer are sealed and connected by water-based hot melt adhesive to form a bag body with a bag opening on one side; one end of the dialysis layer at the bag opening extends beyond the transparent layer and forms a sealing area; the sealing area forms a fold line with other parts of the dialysis layer; an adhesive area is provided on the sealing area; a release paper is provided on the adhesive area; the adhesive area is used to fold the sealing area along the fold line and bond it to the transparent layer to seal the bag opening; an anti-puncture component is provided inside the bag body; the anti-puncture component includes a plastic strip, a plastic slider, and a PE chain; a plastic strip extending towards the bottom of the bag body is symmetrically provided on the left and right sides of the bag opening on the dialysis layer or transparent layer inside the bag body; a plastic slider is slidably provided on each plastic strip; two plastic sliders are connected together by a PE chain; the PE chain includes a convex rib and a grooved rib; the convex rib on the convex rib is used to cooperate with the groove on the grooved rib to form a snap-fit.

[0007] Furthermore, the plastic slider can be directly slidably mounted on the plastic strip or assembled onto the plastic strip during use to form a sliding fit.

[0008] Furthermore, it also includes a protective sleeve; the protective sleeve is used to heat-melt bond the two sides of the opening end for inserting surgical instruments to the raised ridge strip and the groove strip, respectively.

[0009] Furthermore, the protective sleeve is made of dialysis paper. The use of dialysis paper facilitates the disinfection of the parts inside the protective sleeve by sterilizing agents.

[0010] Furthermore, the protective sleeve has a first piece and a second piece formed by folding; a protective space is formed between the first piece and the second piece to protect the insertion site of surgical instruments; one end of the first piece is heat-fused to a convex ridge strip, and one end of the second piece is heat-fused to a groove strip; the other end of the first piece and the other end of the second piece are connected as one piece, and a crease is formed at the connection.

[0011] Furthermore, a through hole is provided at the connection between the first and second pieces. This through hole is used to restrict the sharp or pointed parts of surgical instruments (i.e., when such surgical instruments are bagged, the sharp parts pass through the through hole, and the diameter of the through hole restricts and protects the sharp or pointed parts), further preventing punctures to the bag. At the same time, the through hole can also position the insertion part of some surgical instruments to prevent the surgical instruments from moving around inside the bag.

[0012] Furthermore, multiple rivet caps are fixedly installed on the left side of the outer edge of the bag along the extension direction of the left side seal; multiple rivets are fixedly installed on the right side of the outer edge of the bag along the extension direction of the right side seal; the rivet caps and rivets correspond one-to-one. This design facilitates the placement of the surgical instruments into the sterilization equipment after connection, and also makes it easier for medical staff to physically connect the surgical instruments to be used according to the surgical instrument list, so as to carry out inventory and prevent omissions.

[0013] Furthermore, a plastic strip extending towards the bottom of the bag is symmetrically arranged on both sides of the dialysis layer inside the bag, located at the bag opening; the transparent layer has a notch that exposes one end of the plastic strip at the bag opening; after the adhesive area of ​​the dialysis layer is bonded to the transparent layer, the sealing area of ​​the dialysis layer seals the bag opening and the notch. The notch on the transparent layer for exposing the plastic strip is to facilitate the sliding of the plastic slider and the plastic strip when assembling the anti-puncture component during bagging.

[0014] Furthermore, the aforementioned dialysis layer is marked with sterilization symbols.

[0015] Furthermore, the groove on the plastic slider and the plastic strip can be fitted with a clearance, which has the advantage that the plastic slider can slide along the plastic strip with a very small pushing force.

[0016] As a design feature, the groove and plastic strip on the plastic slider can be fitted with a transition fit. Specifically, as the plastic slider slides from the bag opening to the bottom, it gradually changes from a clearance fit to an interference fit. This design allows the plastic slider to slide smoothly and easily when the surgical instrument is first inserted, but once the surgical instrument is fully inside the bag, the interference fit can achieve a certain degree of locking, thus locking the position of the surgical instrument inside the bag to prevent problems such as bag breakage caused by shaking.

[0017] This utility model has the following positive effects: (1) This utility model can effectively prevent surgical instruments from puncturing the bag during packaging and during transportation and sterilization. At the same time, the bag making process of this utility model is simple, no special equipment is required, and the cost control is ideal (plastic sliders, PE chains and protective sleeves can all be produced separately, and only need to be assembled later or when in use).

[0018] (2) In this utility model, the through hole on the protective sleeve is used to restrict the sharp part of the surgical instrument with a sharp point (that is, when such surgical instruments are bagged, the sharp part passes through the through hole, and the diameter of the through hole is used to restrict and protect the sharp part or the point), further preventing the bag from being punctured. At the same time, the through hole can position the insertion part of some instruments to prevent the instruments from shaking inside the bag.

[0019] (3) In this utility model, the two bags can be assembled and connected by the rivets and rivet caps on the left and right sides (that is, the rivets of the upper bag and the rivet caps of the lower bag are matched to form a snap fastener). This design makes it convenient for the surgical instruments to be connected and put into the sterilization equipment as a whole. It also makes it convenient for medical staff to make the associated physical connection of the surgical instruments to be used according to the surgical instrument list, so as to count and prevent omissions.

[0020] (4) The notch on the transparent layer in this utility model is for the purpose of making the plastic slider and the plastic strip slide together when assembling the anti-puncture component during bagging.

[0021] (5) When the plastic slider and the plastic strip are fitted with a clearance, the plastic slider can slide along the plastic strip with a very small pushing force, resulting in a good user experience.

[0022] (6) When the plastic slider and the plastic strip are fitted with an interference fit, the plastic slider can slide smoothly and be easily inserted when the surgical instrument is first inserted. However, after the surgical instrument is completely inserted into the bag, it can be locked to a certain extent by interference fit, thereby locking the position of the surgical instrument in the bag to a certain extent, so as to prevent the shaking from causing the bag to break.

Detailed Implementation

[0031] (Example 1)

[0032] See Figures 1 to 3 This embodiment includes a bag body; the bag body comprises a dialysis layer 1 and a transparent layer 2; the dialysis layer 1 is dialysis paper; the transparent layer 2 is a transparent composite film; the dialysis layer 1 and the transparent layer 2 are sealed together by water-based hot melt adhesive to form a bag body with an opening on one side; one end of the dialysis layer 1 at the bag opening extends beyond the transparent layer 2 and forms a sealing area 11; the sealing area 11 and other parts of the dialysis layer 1 form a fold line 3; an adhesive area is provided on the sealing area 11; a release paper 12 is provided on the adhesive area; the adhesive area is used to fold the sealing area 11 along the fold line 3 and bond it to the transparent layer 2 to seal the bag. The bag is sealed at the opening; the bag body is provided with an anti-puncture component 4; the anti-puncture component 4 includes a plastic strip 41, a plastic slider 42 and a PE chain 43; a plastic strip 41 extending towards the bottom of the bag body is symmetrically provided on the left and right sides of the dialysis layer 1 or transparent layer 2 inside the bag body; a plastic slider 42 is slidably provided on each plastic strip 41; two plastic sliders 42 are connected together by a PE chain 43; the PE chain 43 includes a convex rib 431 and a groove 432; the convex rib on the convex rib 431 is used to cooperate with the groove on the groove 432 to form a snap-fit.

[0033] It also includes a protective sleeve 44; the protective sleeve 44 is used to heat-melt bond the two sides of the opening end for inserting surgical instruments to the raised ridge strip 431 and the groove strip 432, respectively. The protective sleeve 44 is made of dialysis paper. The use of dialysis paper facilitates the sterilization of the parts inside the protective sleeve 44 by sterilizing agents.

[0034] The protective sleeve 44 has a first piece 441 and a second piece 442 formed by folding; a protective space is formed between the first piece 441 and the second piece 442 to protect the insertion site of surgical instruments; one end of the first piece 441 is heat-fused to the convex strip 431, and one end of the second piece 442 is heat-fused to the groove strip 432; the other end of the first piece 441 and the other end of the second piece 442 are connected as one piece, and a crease is formed at the connection.

[0035] A through hole 443 is provided at the connection between the first piece 441 and the second piece 442. This through hole 443 is used to restrict the sharp or pointed parts of surgical instruments (i.e., when such surgical instruments are bagged, the sharp parts pass through the through hole 443, and the diameter of the through hole 443 restricts and protects the sharp or pointed parts), further preventing punctures to the bag. Simultaneously, the through hole 443 can also position the insertion part of some surgical instruments to prevent them from shifting within the bag.

[0036] Multiple rivet caps 5 are fixedly installed on the left side of the outer side of the bag, extending along the direction of the left side seal; multiple rivets 6 are fixedly installed on the right side of the outer side of the bag, extending along the direction of the right side seal; the rivet caps 5 and rivets 6 correspond one-to-one. This design facilitates the placement of the surgical instruments into the sterilization equipment after connection, and also makes it easier for medical staff to physically connect the surgical instruments to be used according to the surgical instrument list, so as to count and prevent omissions.

[0037] The dialysis layer 1 is marked with a sterilization symbol.

[0038] Furthermore, in this invention, the groove on the plastic slider 42 and the plastic strip 41 can be fitted with a clearance, which has the advantage that the plastic slider 42 can slide along the plastic strip 41 with a very small pushing force.

[0039] As an optimized design, the groove on the plastic slider 42 and the plastic strip 41 can adopt a transition fit. Specifically, the transition fit is as follows: as the plastic slider 42 slides from the bag opening to the bottom of the bag, it gradually changes from a clearance fit to an interference fit. This design allows the plastic slider 42 to slide smoothly and easily when the surgical instrument is first inserted, but after the surgical instrument is fully inserted into the bag, the interference fit can achieve a certain degree of locking, thereby locking the position of the surgical instrument inside the bag to a certain extent and preventing problems such as bag breakage caused by shaking.

[0040] The usage process of this embodiment is as follows: Medical staff take out the sterilization packaging bag. At this time, the plastic slider 42 is located at the bag opening, so the PE chain 43 and the protective sleeve 44 are both at the bag opening, and the PE chain is generally in the open state at this time. Then, while the medical staff puts the surgical instruments to be sterilized into the bag opening, they insert the insertion part of the surgical instruments into the protective sleeve 44. As the surgical instruments are inserted, the plastic slider 42 will slide towards the bottom of the bag. After the surgical instruments are completely inside the bag, the medical staff closes the PE chain 43 by pressing (closed until the surgical instruments are clamped) to properly fix the surgical instruments; then the release paper 12 of the sealing area 11 is removed and folded to seal the bag opening. The final bagging effect is visible. Figure 4 .

[0041] After medical staff have bagged all surgical instruments, bags that require physical connection can be fastened together using pins 6 and pin caps 5, for purposes such as joint disinfection, verification, or as a whole assembly before being pushed into the operating room. (See also...) Figure 5 .

[0042] Of course, if the protective sleeve 44 is not used in some embodiments, the surgical instrument can be partially passed through the PE chain 43 first, and then the PE chain 43 can be closed by pressing (closed until the surgical instrument is clamped), and then the surgical instrument can be pushed into the bag. During this process, the plastic slider 42 can also slide along the plastic strip 41.

[0043] (Example 2)

[0044] See Figure 6 In this embodiment, the plastic slider 42 is assembled onto the plastic strip 41 during use (i.e., when medical personnel bag surgical instruments) to form a sliding fit. At this time, the transparent layer 2 has a notch 21 that exposes one end of the plastic strip 41 at the bag opening. After the adhesive area of ​​the dialysis layer 1 is bonded to the transparent layer 2, the sealing area 11 of the dialysis layer 1 seals the bag opening and the notch 21. The notch 21 on the transparent layer 2 for exposing the plastic strip 41 facilitates the sliding fit between the plastic slider 42 and the plastic strip 41 when assembling the anti-puncture component 4 during bagging.

[0045] Other technical features are the same as in Example 1.

[0046] The usage process of this embodiment is as follows: Medical staff take out the sterilization packaging bag, with the plastic strip 41 exposed at the notch 21; then, the medical staff take out the matching PE chain 43 with plastic sliders 42 at both ends, and slide the plastic sliders 42 from the notch 21 onto the corresponding plastic strips 41. Then, while the medical staff puts the surgical instruments to be sterilized into the bag opening, they insert the insertion part of the surgical instruments into the protective sleeve 44, and as the surgical instruments are inserted, the plastic sliders 42 will slide towards the bottom of the bag. After the surgical instruments are completely inside the bag, the medical staff closes the PE chain 43 by pressing (closed until the surgical instruments are clamped) to properly fix the surgical instruments; then, the release paper 12 of the sealing area 11 is removed and folded to seal the bag opening.

[0047] After the medical staff have bagged all the surgical instruments, the bags that need to be physically linked can be fastened together with pins 6 and pin caps 5, so that they can be disinfected together, checked, or pushed into the operating room as a whole after being connected.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
