Description

A device for recovering target components of medical cavity contents

technical field

The invention relates to a device composed of a suspension container, a step-by-step filter device and a target component collection device, in particular to a medical device for recovering target components from the contents of a human cavity, and belongs to the technical field of medical devices.

Background technique

The contents of the human gastrointestinal tract include food residues, flora, parasite eggs and other active components, as well as body fluid components secreted by the intestinal tract, foreign bodies and liquids that enter the cavity due to various reasons, and endoscopic Finely divided tumor tissue that has been resected but is not easy to remove directly. In the clinical and research process, the only way to distinguish and obtain these target components is to rely on effective instrument-assisted separation. Taking the clinical background of preparing fecal bacteria transplantation liquid and collecting a large number of fecal eggs as an example, the importance of collecting the target components of human cavity contents is briefly explained below.

The flora in the intestinal tract of normal people has been considered as a special organ in the human body, and fecal microbiota transplantation is considered a special organ transplantation. There are about 1,000 to 1,050 species of bacteria in the gut. At present, the functions of most of these bacteria and the mechanism by which different bacteria work organically are still unclear. Recently, modern medicine has increasingly recognized the important role of intestinal bacteria in the human body, and has taken maintaining or rebuilding the normal intestinal flora of the human body as an important treatment for many diseases. Commonly used probiotic drugs and foods are just one or several types of bacteria in the intestine, which are specially cultured in vitro, and then packaged according to a certain amount. However, because the number and types of bacteria incorporated into the human gut are very limited, their therapeutic value is also limited. In the past 5 years, fecal microbiota transplantation has gradually gained attention, especially for infection-related diseases that are ineffective in the treatment of commonly used antibiotics and other drugs, its therapeutic value is particularly important, such as the treatment of antibiotic-associated diarrhea, refractory inflammatory bowel disease, refractory Treatable irritable bowel syndrome, immune-related refractory diarrhea, obesity, food allergy, intestinal symptoms of depression, fatty liver, etc.

Since the development of science, although there have been a few studies on the delivery of fecal suspension or fecal suspension into the gastrointestinal tract through colonoscopy, gastroscopy, nasogastric tube, jejunal tube, capsules, etc., to achieve fecal bacterial transplantation, these methods exist. The following problems: (1) The medical staff who prepare the feces suffer from the visual and psychological discomfort of the feces, and some even refuse these jobs; (2) The non-standardization of the preparation procedure will lead to an increase in the labor cost of the treatment procedure; (3) Previous studies were all about how to avoid the possibility of parasite intestinal infection of feces, which lacks a new breakthrough in the methodology of fecal microbe transplantation, that is, while obtaining the bacterial fluid, it is necessary to effectively filter out worm eggs to prevent parasitism (4) Conventional artificial filtration measures are difficult to ensure reliable and controllable quality of fecal fungus samples. Therefore, the present invention consists in devising a standardized device for the preparation, filtration and collection of liquid manure. There are clinical reports on manual preparation of fecal bacteria liquid by coffee machine abroad. However, such an approach not only wastes homogenization and filtration equipment, is time-consuming and laborious during the operation, but also is a psychologically challenging test for medical staff who handle a bucket of stool. At present, there are no domestic and foreign papers and patent documents disclosing standardized instruments for the preparation of fecal liquid.

Another important clinical need is the collection of large numbers of eggs from feces. Finding intestinal worm eggs is the gold standard for diagnosing intestinal parasitic diseases. Parasitic diseases are rare in western developed countries, and the clinical need for collecting eggs is no longer prominent. However, parasitic diseases are still very common in underdeveloped areas such as China, Southeast Asia, and Africa. The classic way to check for eggs is to use a very small amount of feces to prepare a smear, and then look for eggs under a microscope. Such an inspection method has a low positive detection rate, which easily leads to missed diagnosis of parasitic infection. The invention can realize the collection of excreted feces or intestinal fluid components sucked under the endoscope, and after being prepared into a feces suspension, the worm eggs existing in the feces can be efficiently obtained through continuous filtration designs of different diameters.

Another clinical need is to use endoscopically aspirated gastrointestinal fluid for laboratory testing, the main purpose of which is to obtain liquid components, however, various solid components such as food residues must be mixed during the suction process; The aspirated bladder fluid is used for laboratory examination, and its main purpose is to obtain the liquid and exfoliated cells and other formed components. However, solid components such as stones and other large residues in the urine may be mixed during the suction process; The main purpose of tracheal endocrine fluid and lavage fluid is to obtain liquid and exfoliated cells and other formed components, but there are obvious tissue pieces and thick sputum mixed in it. Devices that filter to remove debris play an important role in the quality and quantity of fluid collected. This clinical need can be met in the above instruments for collecting fecal liquid.

Based on the clinical needs such as the above, a device for recovering the target components of the human cavity contents in vitro is designed, which is widely used in various clinical needs.

The working state of the suspension container (100) is upright when draining.

The inner wall of the suspension container (100) is provided with auxiliary crushing thorns (105) for mixing, stirring and crushing the contents of the cavity. The auxiliary crushing thorns (105) are sharp-edged nails, pieces, and rib-like structures. Geometric structures with sharp edges such as triangular prisms, blade-like shapes, and pointed cones can be added. The appearance of the suspension container (100) can be a drum, a flat bucket, a cube, a cuboid and irregular shapes, and the appearance of the preferred mixing structure is drum-shaped, with a depth of 15.0 cm, an upper opening diameter of 8.0 cm, and a cover; There are liquid inlet channel (101), exhaust or negative pressure suction channel (102). One of the main purposes of its auxiliary pulverizing thorn (105) is to mechanically pulverize the solid feces block that holds collection. Therefore, it is preferable to combine external vibration, shaking, squeezing the periphery of the soft suspension container (100), or internal auxiliary stirring force, so as to easily make the feces mass into a suspension.

The housing of the suspension container (100) is provided with a piston-like prosthesis (106) for occluding each pipeline.

As shown in Figure 2, the step-by-step filtering device (200) is to set at least one filter screen (104) in the suspension container (100), and the shape of the filter screen (104) can be suspended in the suspension container (100) ) is designed as an inverted trapezoidal strip groove with an upward opening, and the surface of the inverted trapezoidal strip groove is a filter screen structure; one side of the upper side of the suspension container (100) is open for the horizontal insertion of the inverted trapezoidal strip groove, and the Or helically positioned to form a closed structure. The filter screen (104) of this form can be conveniently inserted and taken out as a "drawer" like structure, and can also be provided with a handle. When more than one filter screen (104) is provided in the suspension container (100), 2-10 filter screens (104) are continuously stacked on top of each other according to the order of filter hole diameters from large to small. Together, the filter hole diameters of the filter screens (104) are selected between 5.0mm-0.001mm. According to the actual clinical filtration requirements, it is preferable to have the same size and shape of the filter components at all levels, only the filter pore size is different, so that it is convenient to replace the filter screens with different pore sizes, or use prosthetic filter components (without filter screen or large diameter without filtering meaning) filter) replacement to reduce the filter level. The design can meet the specific filter hole diameter of the filter to collect the purpose components.

The filter hole diameter of the filter screen (104) is between 5.0mm-0.001mm, and 1-10 filter screens (104) are arranged from top to bottom according to the order of filter hole diameter from large to small. Filter screens (104) with different filter hole diameters can be co-located in the suspension container (100), and at least one level of filter structure is arranged in the container, and the maximum filter hole diameter of the filter screen (104) is 5mm.

Combined with the automatic or manual oscillation outside the mixing container, the stool is made into a suspension, and the attached bacteria, eggs and other components are fully separated into the suspension for filtration. The continuous mixing process is very important to maintain a good filtration state, especially for the suspension of different solid components. The condition of sufficient mixing is not only important for the first stage suspension filtration, but also for the second and third filtration stages. The device, and the suspension within it, are just as important.

Taking the obtaining of a large number of parasites and fecal bacteria fluids that are most needed clinically as an example, it can be divided into at least 2-3 layers according to the order of filtration: food residues with larger diameters, small fecal clumps that have not been fully homogenized, and parasite fragments. It needs to be filtered out by the first-stage filter screen (104), and the diameter of the filter hole is 3.0mm-4.0mm; if it is the purpose to obtain parasite eggs, then on the basis of selecting 2.0mm filter holes for the next second-stage filter, further Through the third stage of filtration, the filter hole is 0.8mm, and the eggs are located on the filter screen (104) of this 0.8mm level. If it is necessary to further obtain a large number of bacteria, it is also necessary to filter out parasites to avoid parasite infection during fecal bacteria transplantation, because most bacteria are no more than 50 μm in length and 1 μm in width, so the pore size needs to be adjusted Designed for 0.05mm–0.1mm. This multi-stage filtration method can efficiently obtain a large amount of bacterial liquid, remove yellow components, reduce the viscosity of the bacterial liquid, and achieve an odor-free level. On the contrary, if the fecal suspension is directly filtered through a filter hole with a diameter of 0.1 mm, a large amount of suspended solid particles will be blocked on the filter screen, and a large number of bacteria will be attached to these solid components or the blocked space, resulting in The number of bacteria harvested was significantly reduced. If the finely divided tissue is obtained through endoscopy, the patient’s intestines have been cleaned before, and there are very few large-diameter feces in the endoscopic aspiration, so generally only one layer of filter holes with a diameter of 1.0mm–2.0mm is required The left and right filter mesh structure can effectively obtain tissue samples retained on the filter mesh.

All in a filter vessel outside of the suspension vessel. It is provided with a liquid inlet channel (101), an exhaust or negative pressure suction channel (102), and a liquid discharge channel (103) at the bottom. Each filter part is made into an inverted trapezoid, and the structure like a "drawer" is convenient for insertion and removal, and a handle is also provided, that is, the shape of the filter screen (104) is an inverted trapezoidal strip groove with an upward opening, and an inverted trapezoidal The surface of the strip-shaped groove is a filter mesh structure; the upper side opening of the suspension container (100) is inserted into the inverted trapezoidal strip-shaped groove, and is positioned to form an airtight structure by snapping or spiraling. Filter components at all levels are stacked together continuously from top to bottom according to the order of filter hole diameters from large to small. According to the actual clinical filtration requirements, it is preferable to have the same size and shape of the filter components at all levels, only the filter pore size is different, so that it is convenient to replace the filter screens with different pore sizes, or use prosthetic filter components (without filter screen or large diameter without filtering meaning) filter) replacement to reduce the filter level. The design can meet the specific filter hole diameter of the filter to collect the purpose component.

(5) The diameter of the filter hole of the second layer is 2mm, and the layer height is 1.5cm.

(6) The filter hole diameter of the third layer is 0.8mm, which is to obtain insect eggs at this layer, and the layer height is 1.5cm.

(7) The fourth level of filtration with a filter hole diameter of 0.08mm is to further remove the fine particles suspended in the feces, remove the yellow formed components, and obtain a large number of bacteria with high cleanliness while reducing the viscosity of the bacteria liquid. Liquid, layer height 1.5cm.

(8) Bacterial fluid enters another bottled collection container, i.e. the target component collection device (300), through the drainage channel (103). Experimental results prove that, with 500ml homogenate 200g molding feces, through the above steps, the feces collected in the final stage The bacterial liquid is almost colorless, odorless, transparent bacterial liquid; the mouth of the target component collecting device (300) has a screw cap, and there are 2 connecting pipes in the middle of the screw cap, which are respectively used for liquid inlet and negative pressure suction discharge. There are also 2 conical prostheses directly above the outside of the bottle cap, which are used to block the flexible liquid inlet tube and negative pressure suction tube.

(9) When the bottled collection container, that is, the target component collection device (300) is used as the purpose of collecting the fecal liquid, it is used in an upright state, and the liquid inlet pipe is extended outside the bottle cap to connect to the filter device, and extends to the bottom of the bottle inside. About 2.0cm; while the negative pressure suction tube is only flush with the inner surface of the bottle cap in the bottle.

(10) If the collection bottle is turned upside down, it will be used for the infusion of fecal bacteria liquid. At this time, the pipeline for negative pressure exhaust is used for output, and the original pipeline for liquid inlet becomes the pipeline for pressurizing or air intake into the bottle .

(11) The screw cap of the bottled collection container can be replaced by a screw cap with equal caliber and tubeless configuration. The volume of the bottle is 500ml, and the body of the bottle has volume scales in both positive and negative directions; the material of the bottle is the transparent plastic of a medical infusion bottle, preferably light blue The color can avoid light and reduce the effect on bacteria. At the same time, it leaves a good feeling for both staff and patients visually.

(12) The above-mentioned instruments are all disposable, and all of them can be made of plastic.

Although the invention has been described and illustrated herein in terms of one or some specific configurations, it is not intended to be limited to such details, since various modifications and structural changes are possible within the scope of the patent claims without departing from the spirit of the invention.

The parts involved in the present invention are the same as the prior art or can be realized by adopting the prior art.
