Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a filtration and collection device that can drain liquid and separate solid and liquid. Background Technology

[0002] In the field of known technologies, after surgery, medical staff often need to perform multiple tedious operations such as filtration, sedimentation, and collection to separate the tissue / stones from the flushing fluid, thereby extracting samples for component analysis to provide patients with subsequent targeted prevention and treatment plans. The above process is time-consuming and increases workload. In addition, for some patients who need to extract soft tissue for pathological examination during surgery, the mixture is difficult to separate, which can easily lead to tissue / stone loss, causing inconvenience to medical staff.

[0003] The existing product is used in conjunction with a suction sheath. The inlet is connected to the suction sheath, which is inserted into human tissue to absorb liquids and solids from the body. The outlet is connected to a negative pressure suction pump to provide negative pressure to the collection bottle, helping the suction sheath absorb objects from the body. The main function of this type of product is solid-liquid separation. After surgery, doctors need to collect the solids in the bottle for testing.

[0004] While existing products can meet basic surgical needs, some issues remain. For example, although existing bottles can separate liquids and solids, they cannot completely empty the liquid. Clinically, doctors need to manually empty the bottle after surgery by unscrewing the cap and tilting it to pour out the liquid. However, this process can easily spill out solids as well, which is inconvenient for doctors and can contaminate the solids. Another drawback is that a full bottle of liquid remains after solid-liquid separation, increasing the bottle's weight, making it difficult to secure in the clinical setting, and potentially affecting the surgical procedure. There is also a risk of leakage when the bottle is full of liquid.

[0005] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0006] The purpose of this invention is to provide a filtration and collection device that can drain liquid and separate solids and liquids, which can achieve both liquid drainage and solid-liquid separation.

[0010] Preferably, it also includes an outlet switch connected to the water outlet.

[0011] Preferably, the filter sheet is shaped to fit the internal contour of the bottle.

[0012] Preferably, the bottle cap is provided with a hook and a hanging rope.

[0013] Preferably, the bottle cap and the bottle body are connected by a thread or a snap-fit ​​connection.

[0014] Preferably, when the bottle cap and the bottle body are threadedly connected, it further includes a sealing ring fitted on the bottle cap to improve the sealing performance when the bottle cap and the bottle body are threadedly connected, wherein the sealing ring is made of rubber or plastic material.

[0015] Preferably, the surface of the filter is covered with small pores to prevent stones, blood clots, and tissue from clogging the fluid channels.

[0016] Preferably, the filter sheet is provided with reinforcing ribs.

[0017] Preferably, the water inlet of the bottle cap extends beyond the bottom of the bottle cap so that it can extend into the bottle body a predetermined distance after the bottle cap is installed on the bottle body.

[0018] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0019] In this invention, the water outlet is located at the bottom of the bottle body.

The liquid discharge chamber is connected to the water outlet, and the tissue collection chamber is connected to the water inlet. The water outlet is located at the bottom of the bottle body to solve the problem of liquid residue inside the bottle. This invention achieves both solid-liquid separation and tissue collection functions.

[0020] In summary, this invention optimizes the filtration function, making the aspiration process smoother and reducing the risk of leakage due to easier drainage. This invention improves upon the cumbersome sample filtration process of traditional collection devices, avoiding excessive weight of the bottle due to excessive liquid in the bottle. At the same time, this invention simplifies the sample extraction process, which helps to conduct timely and effective sample component analysis and pathological examination, thereby improving the efficiency of doctors' work.

[0030] Please refer to Figures 1 to 5 A filtration and collection device capable of draining liquid and separating solid and liquid includes a bottle body 5 with a cap 2, an inlet 1 on the cap 2 for communicating with the interior of the bottle body 5, and an outlet 5-1 on the bottle body 5. The outlet 5-1 is located at the bottom of the bottle body 5. A filter 4 is inclinedly arranged inside the bottle body 5 to divide the interior of the bottle body 5 into a tissue collection chamber 5-2 and a liquid discharge chamber 5-3. The liquid discharge chamber 5-3 is connected to the outlet 5-1, and the tissue collection chamber 5-2 is connected to the inlet 1, for realizing liquid drainage and solid-liquid separation.

[0031] Preferably, a guide device 5-4 is provided in the bottle body 5 to guide the filter sheet 4 to be placed at an angle. The filter sheet 4 is placed at an angle in the bottle body 5 through the guide device 5-4.

The guide rails or guide grooves extend from the upper part of the bottle body to the lower part of the bottle body and are long rails or long guide grooves that are inclined. The two outer sides of the filter sheet 4 are provided with grooves that cooperate with the guide rails or the two outer sides of the filter sheet 4 are cooperated with the corresponding guide grooves.

[0032] In this invention, the filter element 4 is placed at an angle within the bottle body 5. The guide device 5-4 consists of two symmetrical guide rails or guide grooves. Correspondingly, the filter element 4 has two grooves that engage with the guide rails, or the outer sides of the filter element 4 engage with the corresponding guide grooves, facilitating sliding and providing support and positioning. This invention facilitates the assembly and disassembly of the filter element 4, prevents incorrect installation by the user, and reduces the difficulty of use. Furthermore, the guide device 5-4 provides support and fixation for the filter element 4.

[0033] Preferably, it also includes an outlet switch 6 connected to the water outlet 5-1, which can control the magnitude of the suction negative pressure in the bottle body 5.

[0034] Preferably, the filter element 4 is shaped to fit the internal contour of the bottle body 4 to prevent tissues from passing through the filter element and causing the filtration function to fail. The filter element 4 can be integral or detachable, and its filtration function is achieved through its fine-mesh structure.

[0035] Preferably, the bottle cap 2 is provided with a hook 7 and a hanging rope 8, which can realize the hanging function.

[0036] Preferably, the bottle body 5 is provided with a locking structure that matches the bottle cap 2. For example, the bottle cap 2 and the bottle body 5 are connected by a thread or a snap-fit ​​connection, which is the prior art and will not be described in detail here.
