Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a sterile surgical pathology specimen container. Background Technology
[0002] Pathological specimens are samples of tissues, organs, cells, or body fluids taken from the human or animal body for pathological examination. These specimens are usually obtained during surgery, puncture, biopsy, etc., and are mainly used to observe their cell morphology, tissue structure and other characteristics to help diagnose diseases and determine the nature of lesions. When pathological specimens are obtained during surgery, appropriate containers need to be used to load the pathological specimens.
[0003] Currently, intraoperative pathological specimens are typically collected using specimen bags of various sizes. However, the use of specimen bags usually presents the following problems: First, staff need to manually pour formalin into the specimen bag. Since the bag opening is not restrained, leakage is likely to occur during the pouring process, endangering the health of medical personnel. Second, when using specimen bags to collect pathological samples, there is a lack of sorting and storage functions, which can easily lead to specimen mixing and affect subsequent testing.
[0004] Therefore, in order to address the shortcomings of existing intraoperative pathological specimen extraction methods, a sterile surgical pathological specimen container can be designed. The container has two specimen compartments inside, which are divided into multiple chambers by a movable and detachable partition, allowing it to be freely adjusted according to the size of the specimen. It is also equipped with a corresponding liquid dispensing structure, which allows for automatic liquid dispensing when connected to an external liquid dispensing device. Utility Model Content
[0005] To overcome the shortcomings of existing methods for intraoperative pathological specimen collection, which require staff to manually pour formalin into specimen bags, and which are prone to leakage during pouring due to the lack of restraint at the bag opening, endangering the health of medical personnel, and which lack the function of classifying and storing pathological samples, leading to specimen mixing and affecting subsequent testing, this application provides a sterile surgical pathological specimen container.
[0006] The technical solution is as follows: A sterile surgical pathology specimen container includes a box body, a liquid dispensing mechanism, a split frame, a liquid dispensing hose, and a sealing cap; a sealing cap for sealing the box body is provided on the top of the box body; two sets of specimen compartments are provided inside the box body; a split frame for separating the two sets of specimen compartments is provided between the two sets of specimen compartments; multiple partitions are linearly arranged inside the specimen compartments; multiple specimen cavities are provided between the multiple partitions; a liquid dispensing mechanism for dispensing liquid to the multiple specimen cavities is provided on the top of the two sets of specimen compartments; and a liquid dispensing hose for connecting external liquid dispensing equipment and the liquid dispensing mechanism is provided on one outer end of the box body.
[0007] Furthermore, multiple sets of fixing slots are linearly opened at the bottom and side walls of both sets of specimen compartments. The bottom and sides of the multiple sets of partitions are equipped with fixing strips corresponding to the fixing slots. The fixing slots and fixing strips match and engage. By matching and engaging the fixing strips of the partitions with the fixing slots of the specimen compartments, the partition layout inside the specimen compartments can be flexibly adjusted according to the size, quantity and type of different specimens.
[0008] Furthermore, multiple sets of liquid level grooves corresponding to the specimen chamber are linearly opened on both sides of the split frame. Each liquid level groove is equipped with a liquid level float. The front end of the box is equipped with a control panel for controlling automatic liquid injection. The liquid level float is electrically connected to the control panel. Through the cooperation of the liquid level float and the control panel, the liquid level in the specimen chamber can be monitored in real time.
[0009] Furthermore, the injection and dispensing mechanism includes a main dispensing tube located at the top edge of the front end of the two sets of specimen compartments. One end of the main dispensing tube, near the infusion tubing, extends through the box body to the outside of the box body. One end of the infusion tubing is equipped with a miniature solenoid valve. The infusion tubing and the main dispensing tube are connected through the miniature solenoid valve, which is electrically connected to the control panel. Through the injection and dispensing mechanism, the infusion tubing, and the miniature solenoid valve, the automatic injection of formalin can be achieved.
[0010] Furthermore, the outer end of the main distribution tube is provided with two sets of auxiliary distribution tubes. The two sets of auxiliary distribution tubes are located at the top edge of the two specimen chambers on opposite sides. The outer ends of the two sets of auxiliary distribution tubes are linearly provided with multiple sets of injection connectors corresponding to multiple specimen chambers. The edges of the two specimen chambers are provided with pipe fixing grooves for accommodating the main distribution tube, auxiliary distribution tubes and injection connectors. Through the combined design of the main distribution tube, auxiliary distribution tubes and injection connectors, the injection process is made more efficient. The liquid can be quickly delivered to each auxiliary distribution tube through the main distribution tube, and then accurately injected into the corresponding specimen chamber by the injection connector.
[0011] Furthermore, an infusion flow rate regulator is installed in the middle section of the infusion tubing, and a cap is fitted on the end of the infusion tubing away from the main distribution pipe. Multiple tubing clips for fixing the infusion tubing are installed on the outer side wall of the box near the infusion tubing. The infusion flow rate regulator installed in the middle section of the infusion tubing can flexibly adjust the liquid delivery speed according to actual needs.
[0012] Furthermore, two sets of connecting hinges are symmetrically arranged between the rear ends of the box body and the sealing cover. The box body and the sealing cover are movably connected by the two sets of connecting hinges. The lower end of the sealing cover is provided with a sealing gasket for sealing the two sets of specimen compartments. The combination of the two sets of connecting hinges allows the sealing cover to be opened and closed flexibly.
[0013] Furthermore, two sets of locking modules are symmetrically arranged between the front end of the box body and the sealing cap. The box body and the sealing cap are locked and sealed by the two sets of locking modules. The two sets of locking modules can ensure that the sealing cap is firmly fixed to the box body when closed, avoiding accidental drop and damage to the specimen.
[0014] The beneficial effects are that, compared to the shortcomings of existing intraoperative pathological specimen extraction methods, this application replaces manual pouring with an injection dispensing mechanism and infusion tubing, reducing the risk of formalin contact and protecting the health of medical staff. The partition, along with fixing strips and slots, enables flexible zoning, ensuring independent storage of different specimens and preventing cross-contamination. The injection dispensing mechanism, combined with a level float, enables level monitoring, ensuring uniform injection into each specimen cavity and reducing manual intervention. The sealing cap and locking module ensure a tight seal, preventing leakage and making it suitable for rapid intraoperative use. Simultaneously, staff can directly place the excised tissue into the corresponding specimen cavity, adjust the partition, and immediately seal the box, reducing the specimen's exposure time to air and lowering the probability of bacterial / fungal contamination. With sterile vacuum packaging, it can be used directly in open or laparoscopic surgery. Attached Figure Description

[0022] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Aseptic surgery refers to a type of surgery in which a series of strict aseptic techniques and measures are taken during the operation to prevent bacteria and other microorganisms from entering the surgical area, avoid surgical site infection, and ensure surgical success and patient safety. Preoperative preparation is crucial. Surgical team members must strictly follow the guidelines for handwashing and disinfection, and wear sterile surgical gowns and gloves. Surgical instruments and supplies must undergo strict sterilization treatment, which can be achieved by methods such as high-temperature and high-pressure steam sterilization, chemical disinfectant immersion sterilization, and ethylene oxide gas sterilization to ensure that aseptic standards are met. The operating room must also be thoroughly cleaned and disinfected, and an air purification system should be used to filter microorganisms in the air to maintain the cleanliness of the air in the operating room.
[0024] During the surgery, all procedures must adhere to aseptic principles. Surgical personnel should maintain the integrity of the sterile area, avoid contact with non-sterile items, and take care to prevent contamination when passing instruments. Instruments should not be passed over non-sterile areas. The surgical incision area should be covered with sterile drapes, exposing only the surgical site to minimize contact between the incision and the outside world. For aseptic surgeries, such as gastrointestinal surgeries, care should be taken to protect the surgical field to prevent contamination of the surgical area by gastrointestinal contents. After the surgery, surgical instruments and supplies should be classified and disposed of. Contaminated instruments should be cleaned and then sterilized, and disposable items should be disposed of in accordance with medical waste disposal regulations. The operating room should be cleaned and disinfected again to prepare for the next surgery.
[0025] Pathological samples refer to specimens such as tissues, cells, and body fluids obtained from the human body for pathological examination. Through the analysis of pathological samples, the diagnosis of diseases can be clarified, the type and stage of diseases can be determined, and important evidence can be provided for clinical treatment. The collection of pathological samples must be carried out in strict accordance with the standard. For tissue samples, the surgeon usually removes the diseased tissue during the operation. Representative lesion sites should be selected to avoid obtaining necrotic or normal tissue. For cytological samples, they can be obtained through puncture, scraping, brushing, etc., such as cervical smears for cervical cytology examination and fine-needle aspiration cytology for lung tumors. During the collection process, care should be taken to avoid contamination and damage to the samples to ensure the quality of the samples.
[0026] After collection, pathological samples should be fixed promptly. Formalin solution is commonly used as a fixative, which helps maintain the original morphology and structure of tissue cells and prevents autolysis and putrefaction. The fixation time generally depends on the tissue type and size, usually 6-24 hours. After fixation, the samples need to be dehydrated, cleared, and paraffin-impregnated before being made into paraffin sections. The section thickness is generally 3-5 micrometers. For some special pathological examinations, such as immunohistochemistry and molecular pathology testing, the samples also need to be processed and labeled accordingly. The preservation of pathological samples also has strict requirements. Paraffin sections can be stored for a long time, but attention should be paid to moisture and insect prevention. For the remaining tissue samples, they are generally stored in a refrigerator at 4℃-8℃ after fixation. The storage time depends on the regulations and actual conditions of different hospitals, usually ranging from several months to several years.
[0027] The storage of pathological samples plays a crucial and indispensable role in the entire pathological examination process. A scientifically designed, safe, reliable, efficient, and convenient storage system acts as a sturdy barrier for pathological samples, protecting them from various adverse external factors and preventing contamination and damage. In the past, traditional methods of pathological sample storage mainly relied on common containers such as specimen bags. These containers fulfilled the task of sample storage, but with the continuous development of pathological examination technology and the increasing demands for sample management, their drawbacks have become increasingly apparent. Take glass bottles, for example. Although they offer a certain degree of visibility, allowing for direct observation of the sample's condition, they present many inconveniences in actual operation. Glass bottles are relatively fragile and easily broken during handling. If a specimen bag breaks during transportation or storage, it can not only contaminate the sample but also lead to its loss, severely impacting subsequent testing. While specimen bags are relatively convenient to use, a more significant problem is their lack of proper classification and storage functionality. In actual pathological sample collection, a large number of samples from different patients, sites, and types are often involved. Due to the lack of classification and storage, various specimens are mixed together, which not only makes sample retrieval and retrieval extremely difficult but also easily leads to mutual interference between samples, seriously affecting the accuracy and reliability of subsequent tests. For example, during immunohistochemical testing, if different types of samples are mixed up, it may lead to false positives or false negatives, thus misleading clinical diagnosis.
[0028] Furthermore, the risks associated with pouring formalin fixative during the collection of pathological samples cannot be ignored. Formalin fixative is a commonly used reagent in the fixation of pathological samples, but it is highly volatile and irritating, posing a potential hazard to human health. In traditional sample collection operations, when formalin fixative needs to be poured, leakage is very likely to occur due to the lack of effective protection and operating procedures. Once leakage occurs, the volatilized formalin gas will not only contaminate the collection environment but also directly harm the health of medical personnel. Long-term exposure to such an environment may cause respiratory irritation, allergies, and even increase the risk of cancer.
[0029] Example 1
[0030] like Figures 1-6 As shown, a sterile surgical pathology specimen container includes a box body 1, a liquid dispensing mechanism 4, a split frame 8, a liquid dispensing hose 7, and a sealing cap 5. The sealing cap 5 is matched on the top of the box body 1 for sealing the box body 1. The box body 1 has two sets of specimen compartments 101 inside, and a split frame 8 is provided between the two sets of specimen compartments 101 to separate them. Multiple partitions 3 are linearly arranged inside the specimen compartments 101, and multiple specimen cavities 2 are opened between the multiple partitions 3. The top of the two sets of specimen compartments 101 is provided with a liquid dispensing mechanism 4 for dispensing liquid to the multiple specimen cavities 2. A liquid dispensing hose 7 is provided on one side of the outer end of the box body 1 for connecting external liquid dispensing equipment and the liquid dispensing mechanism 4.
[0031] Multiple sets of fixing slots 9 are linearly opened at the bottom and side walls of the two sets of specimen chambers 101. The bottom and sides of the multiple sets of partitions 3 are provided with fixing strips 24 corresponding to the fixing slots 9. The fixing slots 9 and fixing strips 24 are matched and engaged.
[0032] The two side walls of the split frame 8 are linearly opened with multiple sets of liquid level tanks 14 corresponding to the specimen chamber 2. Each liquid level tank 14 is equipped with a liquid level float 15. The front end of the box body 1 is equipped with a control panel 11 for controlling automatic liquid injection. The liquid level float 15 is electrically connected to the control panel 11.
[0033] The liquid dispensing mechanism 4 includes a main dispensing tube 17, which is located at the top edge of the front end of the two sets of specimen chambers 101. One end of the main dispensing tube 17 near the infusion tubing 21 extends through the box body 1 to the outside of the box body 1. One end of the infusion tubing 21 is equipped with a miniature solenoid valve 20. The infusion tubing 21 and the main dispensing tube 17 are connected through the miniature solenoid valve 20. The miniature solenoid valve 20 is electrically connected to the control panel 11.
[0034] Two sets of auxiliary distribution pipes 18 are provided at the outer end of the main distribution pipe 17. The two sets of auxiliary distribution pipes 18 are located at the top edge of the two specimen chambers 101 on opposite sides. The outer ends of the two sets of auxiliary distribution pipes 18 are provided with multiple sets of injection connectors 19 corresponding to multiple specimen chambers 2. The edges of the two specimen chambers 101 are provided with pipe fixing grooves 10 for accommodating the main distribution pipe 17, auxiliary distribution pipes 18 and injection connectors 19.
[0035] The infusion tubing 21 is equipped with an infusion flow rate regulator 22 in the middle section. The end of the infusion tubing 21 away from the main distribution pipe 17 is fitted with a cap 23. Multiple tubing clips 12 for fixing the infusion tubing 21 are installed on the outer side wall of the box body 1 near the infusion tubing 21.
[0036] Two sets of connecting hinges 6 are symmetrically arranged between the rear ends of the box body 1 and the sealing cover 5. The box body 1 and the sealing cover 5 are movably connected by the two sets of connecting hinges 6. The lower end of the sealing cover 5 is provided with a sealing gasket 16 for sealing the two sets of specimen compartments 101.
[0037] Two sets of locking modules 13 are symmetrically arranged between the front ends of the box body 1 and the sealing cover 5, and the box body 1 and the sealing cover 5 are locked and sealed by the two sets of locking modules 13.
[0038] During the process, the staff first opens the sealing gasket 16 at the bottom of the sealing cover 5 by connecting the box 1 and the sealing cover 5 with two sets of symmetrical hinges 6 at the rear end, which can ensure good sealing in subsequent use. According to the size and number of tissues removed, the staff begins to adjust the specimen chamber 2. As needed, the partitions 3 are inserted into the fixing slots 9 in sequence through the fixing strips 24. These partitions 3 can be flexibly added or removed to divide the specimen compartment 101 into specimen chambers 2 of appropriate size and number, which facilitates the classification and placement of pathological specimens of different parts and types, and effectively avoids the problem of specimen mixing when using specimen bags.
[0039] After the specimen is placed, remove the cap 23 of the infusion tubing 21, connect the external formalin storage device, control the flow rate through the infusion flow rate regulator 22, then close the sealing cap 5, so that the sealing gasket 16 presses the two sets of specimen chambers 101 to ensure airtightness. Then press the control panel 11 to control the micro solenoid valve 20 to open, and formalin is evenly injected into each specimen chamber 2 through the main distribution tube 17, the auxiliary distribution tube 18 and the injection connector 19.
[0040] At this time, the liquid level float 15 reaches the preset height as formalin is injected, and feedback is sent to the control panel 11 to automatically shut off the injection to prevent overflow. Finally, the locking module 13 is fastened to ensure that the box 1 is stable, and the infusion tubing 21 is fixed by the tubing buckle 12 to prevent loosening. Then it is sent to the pathology department for testing.
[0041] Its working principle is as follows: the partition 3, together with the fixing strip 24 and the fixing slot 9, divides the specimen chamber 2 into different sizes to meet the independent storage needs of various specimens. The main distribution pipe 17, the auxiliary distribution pipe 18 and the liquid injection connector 19 of the liquid injection distribution mechanism 4, together with the micro solenoid valve 20, realize automatic and precise liquid injection, avoiding the risk of leakage caused by manual pouring. The liquid level is monitored in real time by the liquid level float ball 15, and the electrical signal is fed back to the control panel 11 to realize automatic start and stop of liquid injection to ensure safety. The sealing cover 5 and the sealing gasket 16 form a sealed space, which is fixed by the locking module 13 to prevent the formalin liquid from evaporating or leaking.
[0042] Its beneficial effects are significant. The injection and distribution mechanism 4, in conjunction with the infusion tubing 21, replaces manual pouring, reducing the risk of formalin contact and protecting the health of medical staff. The partition 3, in conjunction with the fixing strip 24 and fixing slot 9, enables flexible partitioning, ensuring that different specimens are stored independently and avoiding cross-contamination. The injection and distribution mechanism 4, in conjunction with the liquid level float 15, enables liquid level monitoring, ensuring uniform injection into each specimen cavity 2 and reducing manual intervention. The sealing cap 5 and locking module 13 ensure that the box 1 is airtight, preventing liquid leakage. It is suitable for rapid use during surgery. At the same time, staff can directly place the excised tissue into the corresponding specimen cavity 2, adjust the partition 3, and immediately seal the box 1 to reduce the exposure time of the specimen to the air and reduce the probability of bacterial / fungal contamination. With sterile vacuum packaging, it can be used directly for open surgery or laparoscopic surgery.
