Description

Technical Field

[0001] This utility model relates to the field of collection device technology, specifically to a surgical secretion collection bag with measuring function. Background Technology

[0002] During thoracic or abdominal surgery, patients produce secretions. The nature, quantity, and changes in these secretions are of significant clinical value for real-time assessment of the surgical progress, evaluation of the patient's condition, and formulation of subsequent treatment plans.

[0003] Currently, most secretion collection devices used in clinical practice for thoracic or abdominal surgeries are single-cavity collection bags, whose main function is to collect secretions generated throughout the entire surgical procedure. However, existing collection methods have limitations: due to differences in key indicators such as composition, turbidity, and blood content in secretions generated at different stages of surgery, such as the initial stage, lesion resection stage, and hemostasis and suturing stage, existing collection bags cannot achieve separate compartmentalized collection of secretions from different stages, resulting in secretions from all stages being mixed together.

[0004] This problem directly impacts medical staff's analysis of changes in patients' bodily fluids at different stages of surgery, making it difficult to accurately determine the impact of specific surgical steps on patients. This may delay the identification and management of abnormalities, adversely affecting surgical safety and postoperative treatment outcome assessment. Therefore, there is an urgent need for a device capable of collecting secretions in separate compartments according to the surgical stage. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a surgical secretion collection bag with a measuring function, which solves the technical problem that the secretion collection bags used in thoracic surgery can only be used to collect the secretions of the entire surgery at one time, and cannot be collected in separate compartments according to the secretions generated at different stages of the surgery.

[0006] According to one aspect, at least one embodiment of the present invention provides a surgical secretion collection bag with a measuring function for collecting secretions generated by a patient during surgery, comprising:

[0007] A collection box having several fluid storage chambers, each with an opening at the top, for collecting secretions produced at different stages of the surgery.

[0008] A sliding cover plate, wherein there are several sliding cover plates, each of which is slidably disposed on the collection box and penetrates the side wall of the collection box. Each sliding cover plate corresponds to a liquid storage cavity, and the sliding cover plate is used to block the opening of the liquid storage cavity.

[0009] A drainage bag is detachably mounted on the top of the collection box. The top of the drainage bag has an inlet and the bottom has a outlet. The outlet is used to communicate with one of the storage chambers under the sealing action of the sliding cover to guide the secretions generated during the operation into the storage chamber.

[0010] Optional, also includes:

[0011] The mounting frame is disposed on the top of the collection box;

[0012] A limiting member is provided, wherein there are several limiting members, and the limiting members are disposed on the inner peripheral wall of the mounting frame. The limiting members are used to fix the lower edge of the drainage bag to the mounting frame so as to open the drainage port of the drainage bag.

[0013] Optionally, the limiting member includes:

[0014] A squeezing plate is hinged to the mounting frame via a hinge rod. The squeezing plate can swing vertically around the hinge rod to press or release the lower edge of the drainage bag.

[0015] A lifting handle is provided on the extrusion plate. The lifting handle is used to pull the extrusion plate outward so that the upper part of the extrusion plate deforms away from the inner wall of the mounting frame.

[0016] Optionally, the sliding cover has a slot on its side wall, and a fixing seat is provided on the outer side wall of the collection box. A rod is slidably provided on the fixing seat. The rod can slide axially to extend outward and be inserted into the slot so that the sliding cover can open the liquid storage chamber.

[0017] Optionally, the fixing base has an outward-facing sliding groove, the slot is slidably disposed in the sliding groove and is disposed through one side wall of the sliding groove, and one end of the insertion rod has a snap-fit ​​rod body extending out of the sliding groove. The sliding groove is used to limit the sliding range of the snap-fit ​​rod body to limit the extension length of the insertion rod relative to the fixing base.

[0018] The bottom wall of the slide groove is provided with several limiting grooves spaced apart along the axial direction of the insertion rod. The locking rod body can rotate around the main axis of the insertion rod and lock with one of the limiting grooves to lock the axial position of the insertion rod.

[0019] Optionally, the upper edge of the drainage bag is provided with a circumferentially extending annular channel, and a support ring is inserted inside the annular channel to support the drainage bag and form the liquid inlet of the drainage bag.

[0020] Optionally, the upper edge of the drainage bag is provided with a guide band, which is used to receive and guide the secretions into the drainage bag. The guide band has a drainage section and two blocking sections located on both sides of the drainage section. The blocking sections are located on the side of the drainage section near the inlet and are used to prevent the secretions from flowing out of the drainage section.

[0021] Optionally, an adhesive tape is provided on the side of the drainage bag away from the inlet, the adhesive tape being used to attach and fix the drainage bag to the sterile cloth.

[0022] Optionally, the collection box is a transparent box, and scale lines are provided on the side wall of the collection box to display the volume of secreted fluid in the storage chamber.

[0023] Optionally, each of the sliding covers is provided with a handle, and several handles are located at one end of the sliding cover and outside the collection box. The handles are used to drive the sliding cover to slide horizontally.

[0024] The beneficial effects of this utility model are as follows:

[0025] In this invention, the multiple fluid storage chambers within the collection box allow for the separate collection of secretions generated at different stages of surgery. This solves the problem of mixing secretions from different stages caused by existing single-chamber collection bags, providing a foundation for medical personnel to accurately analyze key indicators such as the composition, turbidity, and blood content of secretions at each stage. A sliding cover corresponds to each fluid storage chamber and is slidably mounted on the collection box. The sealing effect of the sliding cover allows the drainage bag's outlet to connect with different fluid storage chambers, facilitating the switching of the collection chamber according to changes in the surgical stage. Because secretions from different stages can be collected independently, medical personnel can clearly understand the changes in the patient's body fluids at each stage of surgery, thereby more accurately assessing the surgical progress and judging the patient's physical condition, providing a reliable clinical reference for developing subsequent treatment plans. Furthermore, if further testing and analysis of the collected secretions is required, the secretions from the corresponding fluid storage chamber can be removed. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0041] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0042] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] like Figures 1-12As shown, this invention illustrates a surgical secretion collection bag with a measuring function, used to collect secretions produced by patients during thoracic or abdominal surgery. The bag includes a collection box 1, a sliding cover 2, and a drainage bag 3. The collection box 1 can be a cuboid, cylindrical, or frustum-shaped structure, etc., made of medical-grade material, and has several independent fluid storage chambers 101 inside. Each fluid storage chamber 101 has an opening 1011 at its top. Secretions produced at different stages of surgery vary in key indicators such as composition, turbidity, and blood content, for example, at the beginning of surgery, during lesion removal, and during hemostasis and suturing. Multiple fluid storage chambers 101 can collect secretions generated at various stages of the operation. Several sliding cover plates 2 are slidably disposed on the collection box 1 and penetrate the side wall of the collection box 1. Each sliding cover plate 2 corresponds to a fluid storage chamber 101 and is used to seal the opening 1011 of the fluid storage chamber 101. A drainage bag 3 is detachably disposed on the top of the collection box 1. The top of the drainage bag 3 has an inlet 301 and the bottom has a drain 302. When a sliding cover plate 2 is opened, the drain 302 can communicate with the corresponding fluid storage chamber 101 to guide the secretions generated during the operation into the fluid storage chamber 101.

[0047] Specifically, at the start of surgery, the sliding cover 2 corresponding to one fluid reservoir 101 is opened, while the others remain closed. Secretions enter this reservoir 101 through the drainage port 302 of the drainage bag 3. During the lesion resection stage, the sliding cover 2 of the previous stage is closed, and the next sliding cover 2 is opened, allowing secretions to be collected in the corresponding reservoir 101. During the hemostasis and suturing stage, collection is switched to the corresponding reservoir 101. This allows for independent collection of secretions at each stage of surgery, avoiding mixed contamination and facilitating comparative analysis of fluid indicators at different stages by medical staff, thus improving the efficiency of abnormal condition identification.

[0048] For example, such as Figure 2 As shown, in some examples, the surgical secretion collection bag with measuring function also includes a mounting frame 4 and limiting members 5. The mounting frame 4 is a frame body adapted to the shape of the outer peripheral wall of the collection box 1 and is integrally formed with the top of the collection box 1. Several limiting members 5 are distributed on the inner wall of the mounting frame 4 and are made of elastic plastic. When installing the drainage bag 3, the lower edge of the drainage bag 3 is inserted into the mounting frame 4, and the limiting members 5 press against the lower edge of the drainage bag 3 around it, so that the drainage port 302 is kept open and aligned with the opening 1011 of the storage cavity 101. This ensures a stable connection between the drainage bag 3 and the collection box 1, avoids the displacement of the drainage port 302 due to vibration during surgery, and improves collection accuracy.

[0049] For example, such as Figure 2 and Figure 12As shown, in some examples, the limiting member 5 includes a squeezing plate 52 and a lifting handle 53. The squeezing plate 52 is hinged to the mounting frame 4 via a hinge rod 51. The squeezing plate 52 can swing vertically around the hinge rod 51 to press or release the lower edge of the drainage bag 3. The lifting handle 53 is provided on the squeezing plate 52 and is used to pull the squeezing plate 52 outward so that the upper part of the squeezing plate 52 moves away from the inner wall of the mounting frame 4.

[0050] The compression plate 52 is fixed to the inner peripheral wall of the mounting frame 4 via a medical-grade hinge rod 51. A retaining spring is provided between the compression plate 52 and the hinge rod 51. The lifting handle 53 is connected to the middle section of the compression plate 52 and has an anti-slip texture on its surface. When installing the drainage bag 3, pull the handle 53 outward to open the upper part of the compression plate 52. After inserting the drainage bag 3, release the lifting handle 53. The compression plate 52 presses the lower edge of the drainage bag 3 under the elastic action of the retaining spring. This allows for quick loading and unloading of the drainage bag 3 and can accommodate drainage bag edges of different thicknesses.

[0051] For example, such as Figure 5 and Figure 7 As shown, in some examples, the sliding cover 2 has a slot 201 on its side wall, and a fixing seat 11 is provided on the outer side wall of the collection box 1. A rod 12 is slidably mounted on the fixing seat 11, and the rod 12 is adapted to the slot 201. It should be noted that when the sliding cover 2 opens the fluid storage chamber 101, pushing the rod 12 so that its end inserts into the slot 201 locks the cover in place; when closing, pulling the rod 12 disengages it from the slot 201 allows the cover 2 to slide. This prevents accidental sliding of the cover during surgery and ensures that secretions accurately flow into the target fluid storage chamber 101.

[0052] For example, such as Figure 4 and Figure 7 As shown, in some examples, the fixed base 11 has a sliding groove 110, and the insertion rod 12 is slidably disposed in the sliding groove 110. The length of the sliding groove 110 of the fixed base 11 matches the length of the insertion rod 12 and is disposed through one side wall of the sliding groove 110. One end of the insertion rod 12 is provided with a snap-fit ​​rod body 121 extending out of the sliding groove 110. The snap-fit ​​rod body 121 is welded to the end of the insertion rod 12 and its length exceeds the sliding groove 110. Several limiting grooves 111 are also provided on the bottom wall of the sliding groove 110, which are spaced apart along the axial direction of the insertion rod 12.

[0053] Specifically, after sliding the insertion rod 12 to the appropriate position, rotating the locking rod body 121 causes it to engage with the corresponding limiting groove 111, thereby achieving axial positioning and locking of the insertion rod 12; to unlock, rotating in the opposite direction allows for sliding. Multiple locking positions are provided to adapt to different usage states of the insertion rod 12.

[0054] For example, such as Figure 4 , Figure 6 , Figure 7 and Figure 9As shown, the insertion rod 12 has two states in the fixed seat 11: one is fully retracted into the fixed seat 11, and the other is extended out of the fixed seat 11. Specifically, when it is necessary to pull out the sliding cover 2, first, the insertion rod 12 is moved to the fully retracted state, and then the sliding cover 2 is pulled out so that the slot 201 of the sliding cover 2 is coaxially aligned with the position of the insertion rod 12. Then, the insertion rod 12 is moved into the slot 201, and then the locking rod body 121 is rotated so that the locking rod body 121 is locked in the limiting groove 111. Finally, the sliding cover 2 is fixed, so that the opening 1011 of the fluid storage chamber 101 required for each stage of the operation is exposed, ensuring that the secretions generated in the corresponding stage of the operation flow into the corresponding fluid storage chamber 101, which makes it easier for medical staff to make a preliminary judgment on the patient's vital signs during the operation by the volume and color of the secretions generated in this stage.

[0055] In addition, when it is necessary to push back the sliding cover 2, firstly, the insertion rod 12 should be pulled out to the fully retracted state, then the sliding cover 2 should be pushed to complete the sealing of the opening 1011 of the fluid storage cavity 101. Next, the insertion rod 12 should be moved until it extends out of the fixing seat 11 and abuts against the surface of the sliding cover 2. Finally, the locking rod body 121 should be rotated so that the locking rod body 121 is locked in the limiting groove 111 closest to the sliding cover 2. This ensures that the fluid storage cavity 101 will not open on its own when the corresponding fluid storage cavity 101 is not in use, thereby improving the sealing performance of the sliding cover 2. This allows the secretions collected at each stage of the operation to accurately correspond to the current stage, and improves the ability of medical staff to make a preliminary judgment on whether the volume or color of the secretions at this stage should be present by observing the state of the secretions at this stage.

[0056] For example, such as Figure 1 As shown, in some examples, the upper edge of the drainage bag 3 is provided with a circumferentially extending annular channel 303, and a support ring 6 is inserted into the annular channel 303. The annular channel 303 is located inside the upper edge of the drainage bag 3; the support ring 6 is arc-shaped in its natural state. The support ring 6 is a flexible rod, which can be fixed at both ends by connectors after being inserted into the annular channel 303, so that the support ring 6 naturally expands the annular channel 303 to form a stable liquid inlet 301, which can quickly recover its shape even after being squeezed by external force. This ensures that the liquid inlet 301 is always in an open state, avoiding drainage obstruction caused by folding and improving collection efficiency.

[0057] For example, such as Figure 10As shown, in some examples, the upper edge of the drainage bag 3 is provided with a guide band 31. The guide band 31 is used to receive and guide the secretions into the drainage bag 3. The guide band 31 has a drainage section 311 and two blocking sections 312 located on both sides of the drainage section 311. The blocking sections 312 are symmetrically distributed on both sides of the drainage section 311. It should be noted that after the secretions drip onto the guide band 31, they flow along the drainage section 311 towards the inlet 301. The blocking sections 312 on both sides prevent the liquid from spreading to the edge. This reduces the leakage loss of secretions and improves the collection rate, which is especially suitable for collecting small amounts of dispersed secretions.

[0058] For example, such as Figure 11 As shown, in some examples, the drainage band 31 has an adhesive tape 32 on its back. The adhesive tape 32 is used to attach and fix the drainage bag 3 to the sterile drape. The adhesive tape 32 can be made of medical-grade adhesive strip material covered with release paper, double-sided adhesive material, or Velcro material. Taking the adhesive strip as an example, specifically, during surgery, the release paper is torn off, and the drainage bag 3 is fixed to the sterile drape of the surgical area using the adhesive tape 32, so that the drainage band 31 is aligned with the site of secretion. This achieves stable fixation of the drainage bag 3, reduces manual operation by medical staff, and lowers the risk of surgical contamination.

[0059] For example, such as Figure 2 As shown, in some examples, the collection box 1 is a transparent box with graduation lines 7 on its side wall. Medical staff can directly observe the color and state of the secretions through the transparent box and read the liquid volume through the graduation lines 7. This enables real-time visual monitoring of the secretions, allowing volume data to be obtained without opening the storage chamber 101, thus reducing the chance of contamination.

[0060] For example, such as Figure 3 As shown, in some examples, each sliding cover 2 is equipped with a handle 8, which is fixed to the middle of the outer end of the sliding cover 2. The surface of the handle 8 is provided with anti-slip protrusions. Medical staff can push and pull the sliding cover 2 by holding the handle 8 to switch the opening and closing of the liquid storage chamber 101. This increases the operating contact area, making it easier to operate while wearing gloves and reducing slippage.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
