Description

Technical Field

[0001] This utility model belongs to the technical field of medical specimen storage devices, and relates to a medical small specimen storage and transportation device. Background Technology

[0002] Tiny specimens, such as minute tissues, organs, or foreign objects related to a patient's disease, often require timely storage, transportation, and testing to obtain pathological examination results, providing a basis for subsequent diagnosis and treatment. However, these tiny specimens are often difficult to obtain, easily damaged, and hard to detect due to their small size. During clinical transportation and testing, they frequently encounter problems such as loss, difficulty in detection, and damage, often making it impossible to obtain pathological results due to the inability to collect them again or even to test them, which has long troubled medical and laboratory personnel. Currently, there are two common methods for storing tiny specimens in clinical practice: one is using small, disposable, self-adhesive specimen bags, and the other is using small glass bottles. Occasionally, cotton swabs or small gauze pads are used to adhere the specimens before placing them in the bottles. However, both methods have numerous problems during specimen transportation and testing, such as the specimens easily falling off the cotton swabs or gauze pads and being difficult to retrieve, and the specimens are easily damaged during repeated searching. Using cotton swabs or small gauze can compromise the integrity of the specimen and affect the testing process, which has long been a problem for medical and laboratory personnel. Therefore, this application aims to solve the above-mentioned technical problems. Utility Model Content

[0003] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0004] Another objective of this invention is to provide a medical specimen storage and transport device.

[0005] The technical solution provided by this utility model is as follows:

[0006] A medical specimen storage and transport device, comprising:

[0007] The outer bottle body; the length of the outer bottle body can be the same as that of the inner bottle body; the outer bottle body can also extend to accommodate the drive assembly to increase structural stability.

[0008] An inner bottle is housed within the outer bottle; the bottom of the outer bottle is integrally connected to the inner bottle; a cavity is defined between the inner wall of the outer bottle and the outer wall of the inner bottle; the bottom of the inner bottle extends through the bottom of the outer bottle to form a drive channel; the drive channel is integrally formed with the inner bottle.

[0009] A liquid storage bag is disposed inside the inner bottle, and the open end of the liquid storage bag is sealed to the inner circumference of the bottleneck of the inner bottle; the open end of the liquid storage bag is fixed to the inner wall at the mouth of the inner bottle, for example, by thermoplasticizing or welding.

[0010] And a drive assembly, which is disposed within the drive channel and moves upward along the drive channel, pushing the bottom of the liquid storage bag upward and releasing a portion of the liquid into the receiving cavity. The function of the drive assembly is to

[0011] Preferably, the drive assembly includes: an active airbag disposed within the drive channel;

[0012] An inflatable source airbag is connected to the bottom of the drive channel and is in gas communication with the drive channel. The inflatable source airbag is inflated in the initial state. When an external force is applied, the inflatable source airbag is squeezed to drive the movable airbag to move upward, pushing the bottom of the liquid storage bag to rise, discharging some liquid, and exposing the tiny specimens stored inside.

[0013] Preferably, the liquid storage bag is made of a flexible film material and is squeezed to release a portion of the liquid under the drive of the movable airbag.

[0014] Preferably, the opening end of the liquid storage bag has an adhesive portion that is bonded to the inner wall of the inner bottle; the length of the adhesive portion is not less than 30% of the length of the liquid storage bag. This prevents the liquid storage bag from folding out of the inner bottle under strong pressure, thus preventing the specimen from being blown out and lost.

[0015] Preferably, a limiting ring is also provided on the inner peripheral wall at the bottom of the drive channel, so that the movable airbag is stopped by the limiting ring in the initial state. The limiting ring is, for example, located 2 cm from the bottom of the drive channel to prevent the movable airbag from falling out of the drive channel due to external force. A similar limiting ring can also be provided at the bottleneck of the inner bottle to prevent excessive downward thrust from blowing the liquid storage bag out of the inner bottle, resulting in sample loss.

[0016] Preferably, the top of the movable airbag has a recess that matches the bottom of the reservoir bag. Due to the recess, when the movable airbag is pushed to its highest point, the recess can also provide a space for the reservoir bag to retain a portion of the specimen.

[0017] Preferably, the inflation source airbag includes: a bottom bulb and a tubular nozzle; the tubular nozzle is sealed to the drive channel and allows gas to pass through. The inflation source airbag may, for example, employ a bulb syringe structure, and squeezing the bulb syringe can blow the movable airbag towards the liquid storage bag.

[0018] Preferably, a filter screen is also provided at the bottom of the liquid storage bag. To further expose the specimen, a filter screen can also be provided at the bottom of the liquid storage bag. After most of the liquid is released, the specimen remains on the filter screen, making it easy for the operator to handle.

[0019] Preferably, the medical specimen collection and transport device further includes a cap, which is detachably connected to the neck of the outer bottle. The opening of the inner bottle is, for example, slightly lower than the opening of the outer bottle. When the cap is placed over the outer bottle, it effectively prevents specimen loss due to accidental tipping over. The cap is, for example, connected to the outer bottle using a threaded structure.

[0020] This invention offers at least the following advantages: The medical specimen collection and transport device described herein can promptly collect and temporarily store tiny specimens collected during surgery. After transport to the laboratory, laboratory personnel can easily squeeze the inflatable airbag to move the movable airbag upwards, pushing against the bottom of the liquid storage bag and expelling excess liquid, thus exposing the tiny specimen placed at the bottom. This eliminates the need for laboratory personnel to repeatedly search through the stored liquid with tweezers. This prevents the loss or damage of tiny specimens, significantly shortens testing time, and ensures the integrity of the specimens, improving testing efficiency. This invention features a simple structure, reasonable design, and convenient use, improving the efficiency of tiny specimen collection, storage, transport, and testing, thereby greatly enhancing medical efficiency.

[0021] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0028] like Figure 1 and Figure 2 As shown, this utility model provides a medical specimen storage and transportation device, which includes:

[0029] An outer bottle 100; an inner bottle 200 housed within the outer bottle 100; the bottom of the outer bottle 100 is integrally connected to the inner bottle 200; a receiving cavity 300 is defined between the inner wall of the outer bottle 100 and the outer wall of the inner bottle 200; the receiving cavity 300 is used to receive liquid overflowing from the storage bag 400. The bottom of the inner bottle 200 extends through the bottom of the outer bottle 100 to form a driving channel 201; the driving channel 201 is integrally formed with the inner bottle 200. The driving channel 201 is, for example, coaxially arranged with the inner bottle 200 and has the same diameter; the length of the driving channel 201 is, for example, the same as or slightly longer than the length of the inner bottle 200.

[0030] A liquid storage bag 400 is disposed inside the inner bottle 200, and the open end 401 of the liquid storage bag 400 is sealed to the inner circumference of the neck of the inner bottle 200; the open end 401 of the liquid storage bag 400 is fixed to the inner wall at the mouth of the inner bottle 200, for example, by thermoplastic molding. The adhesive length between the open end 401 of the liquid storage bag 400 and the inner bottle 200 is not less than 2 cm.

[0031] A drive assembly is provided, which is disposed within the drive channel 500 and moves upward along the drive channel 500, pushing the bottom of the liquid storage bag 400 upward and releasing a portion of the liquid into the receiving cavity 300. The function of the drive assembly is to provide power for the upward movement of the liquid storage bag 300.

[0032] In use, the reservoir bag 400 contains liquid for preserving specimens. Medical personnel can place the collected microscopic specimens into the reservoir bag 400 for temporary preservation. Once transferred to laboratory personnel, the personnel simply use the drive assembly to lift the bottom of the reservoir bag 400, draining some of the liquid, allowing for repeated exposure of the microscopic specimens. Laboratory personnel only need to handle the microscopic specimens. This significantly reduces the time spent searching for specimens and also lowers the chance of damaging the specimens during the search process.

[0033] In one embodiment, such as Figure 2 As shown, the drive assembly includes: an active airbag 601 disposed within the drive channel 500; the active airbag 601 is always inflated and remains within the drive channel 500.

[0034] An inflatable air bladder 602 is connected to the bottom of the drive channel 500 and is in gas communication with the drive channel 500. The inflatable air bladder 602 is initially inflated. Applying external force compresses the inflatable air bladder 602, driving the movable air bladder 601 upwards, pushing the bottom of the liquid storage bag 400 upwards, discharging some liquid, and exposing the tiny specimens stored within. The inflatable air bladder 602, for example, has a diameter much larger than that of the outer bottle 100, thereby ensuring the stability of the device of this invention. The inflatable air bladder 602 is, for example, made of a rubber material with a certain strength, thereby maintaining its shape stability while being easily compressed.

[0035] In one embodiment, such as Figure 3 As shown, the driving assembly includes: a piston 3601, which is housed within the driving channel 500 and tightly fitted against the inner wall of the driving channel 500; and a push rod 3602, which connects to the piston 3601 and pushes the piston 3601 upward along the driving channel 500. The push rod 3602, for example, has a handle with a diameter larger than that of the outer bottle body 100. This further increases the structural stability of the present invention.

[0036] In one embodiment, such as Figure 2 and Figure 3 As shown, the liquid storage bag 400 is made of nitrile material, whose softness ensures that it can be squeezed and release some liquid when driven by the movable airbag. This exposes the small specimens placed in the liquid storage bag 400, making them easier for inspectors to find and handle, thus improving the efficiency of specimen transport and testing.

[0037] In one embodiment, such as Figure 3As shown, the opening end of the liquid storage bag 400 has an adhesive portion 402, which is adhered to the inner wall of the inner bottle 200; the length of the adhesive portion 402 is not less than 30% of the length of the liquid storage bag 400. This prevents the liquid storage bag 400 from folding out of the inner bottle 200 under strong pressure, thus preventing the specimen from being blown out and lost.

[0038] In one embodiment, such as Figure 2 and Figure 3 As shown, a limiting ring 501 is also provided on the inner peripheral wall at the bottom of the drive channel 500. In the initial state, the movable airbag 601 is stopped by the limiting ring 501. The limiting ring 501 is, for example, located 2 cm from the bottom of the drive channel 500 to prevent the movable airbag 601 from falling out of the drive channel 500 due to external force. A similar limiting ring can also be provided at the bottleneck of the inner bottle 200 to prevent excessive downward thrust from blowing the liquid storage bag 400 out of the inner bottle 200, resulting in sample loss.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, the inflation source airbag 602 includes: a bottom bulb 6021 and a tubular nozzle 6022; the tubular nozzle 6022 is sealed to the drive channel 500 and allows gas to pass through. The inflation source airbag 602 may employ a bulb syringe structure, for example, squeezing the bulb syringe can blow the movable airbag 601 toward the liquid storage bag 400.

[0040] In one embodiment, such as Figure 2 and Figure 3 As shown, a filter screen 401 is also provided at the bottom of the liquid storage bag 400. To further expose the specimen, a filter screen 401 can be provided at the bottom of the liquid storage bag 400. After most of the liquid is released, the specimen remains on the filter screen, making it easy for the operator to handle. The filter screen 401 can also support small specimens, facilitating quick detection and handling by laboratory personnel.

[0041] In one embodiment, such as Figure 1 As shown, the medical specimen collection and transport device also includes a cover 700, which is detachably connected to the neck of the outer bottle 100. Figure 2 As shown, the cap 700 also contains an inner cap 701 to cover the inner bottle 200. This ensures the sealing performance of the inner bottle 200 during transport, effectively preventing specimen loss due to accidental tipping. The cap 700 may be connected to the outer bottle using a threaded structure, for example.

[0042] In use, medical staff directly place the collected micro-samples into the storage bag 400, close the lid 700, and then transport it directly to the laboratory. Upon receipt, laboratory personnel can directly open the lid 700 and squeeze the inflation source airbag 602. The movable airbag 601 rises, causing the bottom of the storage bag 400 to rise, expelling some liquid and allowing the micro-samples to be repeatedly exposed. This eliminates the need for laboratory personnel to repeatedly search through the stored liquid with tweezers, preventing the loss or damage of micro-samples.

[0043] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
