Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a closed alveolar lavage fluid collection and transportation kit. Background Art

[0002] Clinical workers have an increasing demand for technologies and equipment for the collection, preservation, delivery and testing of pathogen specimens. In addition, how to better protect clinical medical staff and avoid medical exposure also puts forward higher requirements.

[0003] Committed to starting from practical problems, the inventor searched and read a large number of existing technologies related to closed alveolar lavage fluid collection and transportation kits, but found that most of the existing closed alveolar lavage fluid collection and transportation kits have certain defects, such as: Chinese patent CN108434544A discloses an animal bronchoalveolar lavage fluid acquisition device, which relates to the technical field of medical experimental devices, including a three-way hose, the three ends of which are respectively connected to a negative pressure bottle, an injection needle and an injection needle, and the three branches of the three-way hose are respectively sleeved with a first stop liquid clamp, a second stop liquid clamp and a third stop liquid clamp. In this invention, the injection needle is only used to inject lavage fluid into the animal's lungs, and the negative pressure bottle is only used to extract the lavage liquid. The operator only needs to open or close different stop liquid clamps on the three-way hose to realize the injection and absorption process of the lavage fluid. In addition, a filtering device is provided in the negative pressure bottle to automatically filter the lavage fluid during the absorption process.

[0004] However, after the alveolar lavage fluid acquisition device is used to collect the fluid, it is necessary to remove the old sealing cover and pipette used for collection, and replace them with a new sealing cover to seal the bottle for transportation. When the testing department tests the sample, it is necessary to open the sealing cover again for sampling. This has the following problems: 1) The bottle needs to be opened at the end of collection and when the sample is tested, and there is a problem of sample contamination caused by opening / closing the sealing cover; 2) The discarded auxiliary suction device (old sealing cover and pipette) will continue to be exposed to the air, resulting in the risk of potential air contamination in the operating room, and cannot be destroyed immediately.

[0005] Based on the above situation, the utility model proposes a closed alveolar lavage fluid collection and transportation kit, which can effectively solve the above problems. Utility Model Content

[0006] In order to solve the technical problems raised in the above-mentioned background technology, the utility model provides a closed alveolar lavage fluid collection and transportation kit, which realizes the closed transportation of biological samples (alveolar lavage fluid) from collection in vitro to biological testing, thereby achieving the purpose of protecting the medical environment, medical personnel and avoiding sample contamination.

[0009] Preferably, the membrane closure assembly comprises a sealing membrane and a sealing edge, wherein the sealing membrane covers the through hole at the top of the storage tank body, and the edge of the sealing membrane forms a seal with the top of the storage tank body through the sealing edge.

[0010] Preferably, the sealing film is made of butyl rubber.

[0014] Preferably, a negative pressure suction tube connecting portion is sealed on the top of the storage tank body on one side of the membrane closure assembly, and the first negative pressure suction tube and the second negative pressure suction tube are both penetrated through the negative pressure suction tube connecting portion and sealed therewith.

[0015] Preferably, scale lines are provided on the storage tank body.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments. However, it should be understood that the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationship described in the drawings is only used for illustrative purposes and cannot be understood as a limitation on this patent.

[0023] like Figure 1 As shown, this embodiment provides a closed alveolar lavage fluid collection and transportation kit, including a storage tank body 1, a membrane sealing assembly 2, a first negative pressure suction tube 3, a second negative pressure suction tube 4 and a negative pressure suction tube connecting part 5.

[0024] The storage tank body 1 adopts an integrated sealed design, eliminating the original open / closed closed design, which can isolate the air exposure of potentially infectious alveolar lavage fluid samples to a great extent, and avoid contamination of biological samples. The shape of the storage tank body 1 is usually cylindrical or slightly conical at the bottom, which is convenient for liquid collection and precipitation. According to actual operational needs, the capacity generally ranges from tens of milliliters to hundreds of milliliters, which can accommodate a sufficient amount of lavage fluid for subsequent analysis. In order to ensure that the sample is not contaminated, the collection bottle must be a sterile disposable product, and some leak-proof and pressure-resistant designs can be additionally adopted. The storage tank body 1 is mostly made of medical-grade plastic or glass, which is transparent to observe the color, turbidity and other appearance characteristics of the lavage fluid.

[0025] The membrane closure assembly 2 is sealed and arranged on the top of the storage tank body 1. The membrane closure assembly 2 includes a sealing membrane 2.1 and a sealing edge 2.2. The sealing membrane 2.1 covers the through hole on the top of the storage tank body 1. The edge of the sealing membrane 2.1 forms a seal with the top of the storage tank body 1 through the sealing edge 2.2. Among them, the sealing membrane 2.1 is usually made of a rubber mold made of butyl rubber and other materials. Even after puncture sampling with a sterile syringe, the rubber mold can still play a sealing role, overcoming the potential defect of continuous medical environmental pollution of the discarded device after detection. The sealing edge 2.2 is usually made of aluminum foil by hot pressing or cold pressing to tightly fit the joint between the sealing membrane 2.1 and the storage tank body 1, forming a good sealing effect to prevent sample contamination.

[0026] The first negative pressure suction tube 3 and the second negative pressure suction tube 4 are both fixed to the top of the storage tank body 1 through the negative pressure suction tube connecting part 5. The negative pressure end 3.1 of the first negative pressure suction tube 3 is used to connect to an external negative pressure source, and the suction end 4.1 of the second negative pressure suction tube 4 is used to connect to a suction and lavage device. Among them, the negative pressure source can be a portable negative pressure pump, or a central negative pressure suction device that is equipped in departments such as bronchoscope rooms. This is a negative pressure source connected to the wall through a pipe, which can provide a stable and adjustable negative pressure for sucking the liquid generated during alveolar lavage. The suction and lavage device can be a suction and lavage cannula or a bronchoscope.

[0027] The negative pressure end 3.1 and the suction end 4.1 are connected in a detachable sealed manner. Specifically, the diameter of the negative pressure end 3.1 is larger than the diameter of the suction end 4.1, and the suction end 4.1 can be embedded in the negative pressure end 3.1 to form a seal. Alternatively, a snap-on fast sealing connector conventionally selected in the art is used, including a male and a female part. The negative pressure end 3.1 is provided with a male part with a snap, and the suction end 4.1 is provided with a female interface that matches it. The two are locked with each other by pressing or pushing and pulling to form a stable connection.

[0028] A sealing connection kit is provided on the suction end 4.1 and the negative pressure end 3.1, and the negative pressure end 3.1 and the suction end 4.1 are sealed and connected through the sealing connection kit, ensuring that the negative pressure suction tube and the storage tank body 1 form an integral closed environment, thereby overcoming the potential medical environmental pollution problem of the auxiliary suction device after collection.

[0029] A piston-closed opening 4.2 is provided on the second negative pressure suction tube 4 near the suction end 4.1, so that it can be opened or closed when needed, thereby enhancing the control of the irrigation process and reducing the potential risk of leakage.

[0030] The negative pressure suction tube connection part 5 can be made of elastic material, which can tightly wrap the negative pressure suction tube, thereby forming an effective seal. Alternatively, the negative pressure suction tube connection part 5 is a threaded connection part integrally formed with the storage tank body 1, and the negative pressure suction tube connection part 5 is correspondingly provided with an internal thread, and one end of the negative pressure suction tube is provided with an external thread. By rotating the negative pressure suction tube, the internal and external threads are tightly combined to achieve sealing.

[0031] In order to facilitate the medical staff to perform quantitative analysis on the collected samples, scale lines are provided on the storage tank body 1, and the scale lines are helpful to accurately measure the volume of the irrigation fluid.

[0032] According to the description and drawings of the utility model, those skilled in the art can easily manufacture or use the closed alveolar lavage fluid collection and transportation kit of the utility model, and can produce the positive effects recorded in the utility model.
