Description

Technical Field

[0001] The invention belongs to the technical field of specimen bags, and in particular relates to a specimen collection bag and a sealing mechanism thereof. Background Art

[0002] After surgical excision of pathological tissue, it needs to be placed in a pathological specimen bag, fixed with 10% formaldehyde solution, and then sent to the pathology department for specialists to slice and stain for pathological diagnosis. Formaldehyde aqueous solution is colorless and transparent, corrosive, and has the characteristics of strong irritation to the eye membrane and respiratory organs, which can cause allergic reactions, dermatitis or eczema.

[0003] In clinical work, traditional pathology specimen bags often have many shortcomings during use due to defects in the design of the specimen bags themselves. For example, the existing specimen bags are mostly sealed by operators manually pinching them, and the specimen bags may not be tightly sealed. When the bag is unstable and tilted, the formaldehyde fixative will leak out, and the specimen cannot be effectively fixed, and it will cause harm to the operating room environment and the health of medical staff. In addition, there are no scale lines on the outside of general specimen bags. When operators pour formaldehyde solution into the specimen bags, they cannot accurately grasp the mass of the formaldehyde solution, and it is easy to add too much or too little, which leads to the risk of material waste and unqualified specimen fixation quality. When taking the specimens in the specimen bag, the formaldehyde solution in the specimen bag needs to be poured out first. During the pouring process, the formaldehyde solution will splash out from the mouth of the specimen bag, causing environmental pollution, and there is a certain risk of use. In order to improve the safe management of surgical specimens, it is necessary to improve the existing pathology tissue specimen bags and design a new type of pathology specimen bag. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1 - Figure 6 As shown, a specimen collection bag and a sealing mechanism thereof, comprising:

[0031] The bag body 1 has an upper margin 2 at the upper end thereof, and the upper margin 2 can cover the bag opening of the bag body 1. Even if some formaldehyde solution splashes out of the bag opening, the upper margin 2 can also play a certain shielding role to prevent formaldehyde droplets from being directly scattered in the environment. The side wall of the upper margin 2 is provided with a hand groove 3, and the user can lift the bag body 1 by the hand groove 3 and the upper margin 2, so that the user can take the bag body 1 conveniently. The side wall of the lower end of the bag body 1 has a lower margin 4, and the lower margin 4 can increase the ground contact area of ​​the bag body 1, so that the bag body 1 can be placed stably.

[0032] The scale groove 5 is engraved on the side wall of the bag body 1. The scale groove 5 is set in the middle of the side wall of the bag body 1, and the scale line of the scale groove 5 is parallel to the bottom of the bag body 1. The operator opens the bag mouth to place the bag body 1, and then adds 10% formaldehyde solution into the bag body 1. The mass of the formaldehyde solution added into the bag body 1 can be judged by the scale groove 5 to avoid adding too much or too little formaldehyde solution;

[0033] The drain valve 6 is fixedly connected to the bottom of the side wall of the bag body 1. After the operator turns the drain valve 6, the formaldehyde solution inside the bag body 1 will flow out of the bag body 1 from the drain valve 6, making it convenient for the operator to take the specimen inside the bag body 1;

[0034] The inner bag 8 is arranged inside the bag body 1, and a plurality of drainage holes 9 are opened on the inner bag 8. The side wall of the inner bag 8 is cut to form a connecting belt 10. One end of the connecting belt 10 is fixedly connected to the inner bag 8, and the other end is fixedly connected to the inner wall of the bag body 1. A lifting belt 11 is fixedly connected to the top of the side wall of the inner bag 8. When the user opens the bag body 1 and lifts the inner bag 8 by the lifting belt 11, the formaldehyde solution in the inner bag 8 will leak from the drainage holes 9 to the inside of the bag body 1, so that the specimen is retained in the inner bag 8. The connecting belt 10 can limit the position of the inner bag 8. To prevent the inner bag 8 from being separated from the bag body 1, the bag body 1 and the inner bag 8 are both made of medical PVC material and are transparent, which is convenient for operators to view the specimens in the bag. The bottom of the bag body 1 and the bottom of the inner bag 8 are both set to be flat, which is convenient for the bag body 1 and the inner bag 8 to be stably placed on the plane. The length of the inner bag 8 is less than the length of the upper opening of the bag body 1, which is convenient for users to pull the inner bag 8 out of the bag body 1, and the top strap 11 of the inner bag 8 is made of hard PVC material, which can effectively prevent the strap 11 from being soft and deformed, and is convenient for operators to pick up the strap 11;

[0035] The concave-convex slider clamp chain 12 is fixedly installed at the bottom of the inner wall of the upper residual edge 2. After the formaldehyde solution and the specimen are placed, the bag opening of the bag body 1 can be sealed by the concave-convex slider clamp chain 12, effectively avoiding the situation of loose sealing caused by manually pressing the sealing strip.

[0036] As can be seen from the above, when using the specimen retrieval bag, the user can first open the bag body 1 and place it on a flat surface, add formaldehyde solution into the bag body 1, and determine the amount of formaldehyde solution added through the scale groove 5, place the specimen in the inner bag 8, close the concave-convex slider clamp chain 12 to seal the bag body 1, and when taking the specimen inside the bag body 1, discharge the formaldehyde solution inside the bag body 1 through the drain valve 6, and then open the concave-convex slider clamp chain 12 to take out the specimen in the inner bag 8. If it is necessary to temporarily take out the specimen, the inner bag 8 can be pulled out of the bag body 1 through the carrying strap 11. At this time, the formaldehyde solution in the inner bag 8 flows out from the drain hole 9 and remains in the bag body 1. The user can take the specimen in the inner bag 8, and the formaldehyde solution in the bag body 1 is not lost, and the specimen can be put back into the bag body 1 for continued storage.

[0037] The bag body 1 can be provided in various sizes and specifications, and users can select specimen retrieval bags of different sizes for use according to different usage scenarios.

[0038] Embodiment 2:

[0039] See also Figure 1 - Figure 6 As shown, a specimen collection bag and a sealing mechanism thereof, comprising:

[0040] The bag body 1 has an upper margin 2 at the upper end thereof, and the upper margin 2 can cover the bag opening of the bag body 1. Even if some formaldehyde solution splashes out of the bag opening, the upper margin 2 can also play a certain shielding role to prevent formaldehyde droplets from being directly scattered in the environment. The side wall of the upper margin 2 is provided with a hand groove 3, and the user can lift the bag body 1 by the hand groove 3 and the upper margin 2, so that the user can take the bag body 1 conveniently. The side wall of the lower end of the bag body 1 has a lower margin 4, and the lower margin 4 can increase the ground contact area of ​​the bag body 1, so that the bag body 1 can be placed stably.

[0041] The scale groove 5 is engraved on the side wall of the bag body 1. The scale groove 5 is set in the middle of the side wall of the bag body 1, and the scale line of the scale groove 5 is parallel to the bottom of the bag body 1. The operator opens the bag mouth to place the bag body 1, and then adds 10% formaldehyde solution into the bag body 1. The mass of the formaldehyde solution added into the bag body 1 can be judged by the scale groove 5 to avoid adding too much or too little formaldehyde solution;

[0042] The drain valve 6 is fixedly connected to the bottom of the side wall of the bag body 1. After the operator turns the drain valve 6, the formaldehyde solution inside the bag body 1 will flow out of the bag body 1 from the drain valve 6, making it convenient for the operator to take the specimen inside the bag body 1;

[0043] An exhaust valve 7, wherein the exhaust valve 7 is fixedly connected to the top of the side wall of the bag body 1, and the user can exhaust the air inside the bag body 1 through the exhaust valve 7, so that the formaldehyde solution wraps the specimen as much as possible, thereby effectively fixing the specimen;

[0044] The inner bag 8 is arranged inside the bag body 1, and a plurality of drainage holes 9 are opened on the inner bag 8. The side wall of the inner bag 8 is cut to form a connecting belt 10. One end of the connecting belt 10 is fixedly connected to the inner bag 8, and the other end is fixedly connected to the inner wall of the bag body 1. A lifting belt 11 is fixedly connected to the top of the side wall of the inner bag 8. When the user opens the bag body 1 and lifts the inner bag 8 by the lifting belt 11, the formaldehyde solution in the inner bag 8 will leak from the drainage holes 9 to the inside of the bag body 1, so that the specimen is retained in the inner bag 8. The connecting belt 10 can limit the position of the inner bag 8. To prevent the inner bag 8 from being separated from the bag body 1, the bag body 1 and the inner bag 8 are both made of medical PVC material and are transparent, which is convenient for operators to view the specimens in the bag. The bottom of the bag body 1 and the bottom of the inner bag 8 are both set to be flat, which is convenient for the bag body 1 and the inner bag 8 to be stably placed on the plane. The length of the inner bag 8 is less than the length of the upper opening of the bag body 1, which is convenient for users to pull the inner bag 8 out of the bag body 1, and the top strap 11 of the inner bag 8 is made of hard PVC material, which can effectively prevent the strap 11 from being soft and deformed, and is convenient for operators to pick up the strap 11;

[0045] The concave-convex slider clamp chain 12 is fixedly installed at the bottom of the inner wall of the upper residual edge 2. After the formaldehyde solution and the specimen are placed, the bag opening of the bag body 1 can be sealed by the concave-convex slider clamp chain 12, effectively avoiding the situation of loose sealing caused by manually pressing the sealing strip.

[0046] As can be seen from the above, when using the specimen retrieval bag, the user can first open the bag body 1 and place it on a flat surface, add formaldehyde solution into the bag body 1, and determine the amount of formaldehyde solution added through the scale groove 5, place the specimen in the inner bag 8, close the concave-convex slider clamp chain 12 to seal the bag body 1, and exhaust the excess air inside the bag body 1 through the exhaust valve 7, so that the specimen is completely immersed in the formaldehyde solution, to prevent some lighter specimens from floating on the formaldehyde solution and being unable to be well fixed. When taking the specimen inside the bag body 1, the formaldehyde solution inside the bag body 1 is discharged through the drain valve 6, and then the concave-convex slider clamp chain 12 is opened to take out the specimen in the inner bag 8. If it is necessary to temporarily take out the specimen, the inner bag 8 can be pulled out of the bag body 1 through the carrying strap 11. At this time, the formaldehyde solution in the inner bag 8 flows out from the drain hole 9 and remains in the bag body 1. The user can take the specimen in the inner bag 8, and the formaldehyde solution in the bag body 1 is not lost, and the specimen can be put back into the bag body 1 for continued storage.

[0047] The exhaust valve 7 includes an air pipe 71 fixedly mounted on the bag body 1, a mounting cavity 72 opened in the middle of the air pipe 71 and a blocking ball 73 arranged inside the mounting cavity 72. The inner diameter of the mounting cavity 72 is larger than the inner diameter of the air pipe 71. The outer diameter of the blocking ball 73 is larger than the inner diameter of the air pipe 71 and smaller than the inner diameter of the mounting cavity 72. The density of the material used for the blocking ball 73 is greater than the density of air and less than the density of 10% formaldehyde solution. The end of the air pipe 71 is threadedly connected with a pipe cap 74. The inner wall of the end of the pipe cap 74 is fixedly connected with a blocking block 75. The blocking block 75 is plugged into the end of the air pipe 71.

[0048] When it is necessary to discharge the gas inside the bag body 1, the bag body 1 is first sealed by the concave-convex slider clamp chain 12, and the pipe cap 74 is screwed to make the block 75 separate from the end of the air pipe 71, and then the bag body 1 is slowly squeezed. At this time, the air inside the bag body 1 is gradually discharged outward along the air pipe 71. Since the outer diameter of the card ball 73 is between the inner diameter of the air pipe 71 and the inner diameter of the installation cavity 72, the gap between the card ball 73 and the installation cavity 72 can provide gas flow. The density of the card ball 73 is greater than that of air and less than that of 10% formaldehyde solution. When the air flows inside the air pipe 71, the card ball 73 will not block the internal passage of the air pipe 71. After the gas inside the bag body 1 is exhausted, the formaldehyde solution gradually enters the air pipe 71, and the formaldehyde solution will float up the card ball 73 to block the connection channel between the air pipe 71 and the installation cavity 72. At this time, the formaldehyde solution cannot flow out of the air pipe 71, and the operator can turn the pipe cap 74 to seal the outlet of the air pipe 71 again to exhaust the air inside the bag body 1. Even if some specimens are lighter in weight and will float on the surface of the formaldehyde solution, after the air inside the bag body 1 is exhausted, only the formaldehyde solution and the specimens remain in the bag body 1, which can help the formaldehyde solution to better wrap the specimens and facilitate better fixation of the specimens.

[0049] The bag body 1 can be provided in various sizes and specifications, and users can select specimen retrieval bags of different sizes for use according to different usage scenarios.
