Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a milk secretion collector. Background Art

[0002] Nipple discharge is an important clinical manifestation of breast disease. The most common type of nipple discharge is bloody, followed by serous and milky discharge, and watery and purulent discharge are rare. Bloody discharge is related to breast cancer and intraductal tumors, while other types of discharge are mostly benign breast lesions. Finding tumor cells through nipple discharge is one of the clinical diagnostic methods for intraductal papillary tumors and breast cancer.

[0003] At present, clinical sampling of breast discharge is performed manually by doctors, which results in a poor medical experience for patients. In addition, the outflow of breast discharge is irregular. Clinical experience tells us that manual pressure for discharge cytology examination cannot guarantee that all specimens are successfully collected, especially for small or thick discharge. Summary of the invention

[0004] The purpose of the present invention is to provide a milk overflow sample collector to solve the problems existing in the above-mentioned prior art. During the diagnosis and treatment sampling process, the two methods of suction and squeezing are used in parallel to help medical staff successfully suck out the overflow. The setting of the connecting tube and the cover structure can protect the patient's privacy, improve the medical experience, and prevent the overflow from splashing during the sampling process.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides a breast overflow collection device, comprising a breast shield, a telescopic corrugated connecting tube and a collecting cup, wherein the breast shield and the collecting cup are connected via the telescopic corrugated connecting tube, the breast shield is a trumpet-shaped shield body structure with a diameter of one end larger than that of the other end, the collecting cup is a cup body structure with an expanded opening at one end, one end of the telescopic corrugated connecting tube is connected to a small-diameter end of the breast shield, and the other end of the telescopic corrugated connecting tube extends into the collecting cup through the expanded opening of the collecting cup and is connected to the inner wall of the collecting cup; a syringe interface is also provided on the side wall of the collecting cup away from the expanded opening, and the syringe interface is used to be connected to a syringe for negative pressure suction and to collect overflow at the same time.

[0007] Preferably, a sealing ring is provided on the inner side wall of the breast shield.

[0008] Preferably, a sealing lip is provided at the expanded opening of the collecting cup.

[0009] Preferably, the sealing ring and the sealing lip are both made of silicone.

[0010] Preferably, a vent hole is also provided at the top of one end of the telescopic corrugated connecting tube extending into the collecting cup.

[0011] Preferably, the diameter of the vent hole is less than 1 mm.

[0012] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0013] The breast milk sampling device provided by the present invention can help medical staff to smoothly suck out the breast milk while improving the patient's medical experience, greatly increasing the disease detection rate. The setting of the cover structure can prevent the breast milk from splashing during the sampling process to prevent contamination. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The purpose of the present invention is to provide a milk leakage sample collector to solve the problems existing in the prior art.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The milk collection device in this embodiment is as follows: Figure 1 , Figure 2As shown, it comprises a breast shield 1, a retractable corrugated connecting tube 2 and a collecting cup 3. The breast shield 1 and the collecting cup 3 are connected via the retractable corrugated connecting tube 2. The breast shield 1 is a trumpet-shaped shield body structure with a diameter of one end larger than that of the other end. The collecting cup 3 is a cup body structure with an expanded opening at one end. One end of the retractable corrugated connecting tube 2 is connected to the small-diameter end of the breast shield 1, and the other end is expanded by the collecting cup 3 and extends into the collecting cup 3 and is connected to the inner wall of the collecting cup 3. A syringe interface 4 is also provided on the side wall of the collecting cup 3 away from the expanded end. The syringe interface 4 is used to be connected to a syringe for negative pressure suction and to collect overflow at the same time.

[0022] In this specific embodiment, a sealing ring 7 made of silicone material is provided on the inner side wall of the breast shield 1 to increase the sealing performance between the breast shield 1 and the breast skin during breast pumping. A sealing lip 5 is provided at the expanded opening of the collection cup 3. The sealing lip 5 is made of silicone material and is connected to the collection cup 3 as a whole by a secondary injection molding process. When the retractable corrugated connecting tube 2 is compressed and the collection cup 3 is connected to the breast shield 1, the sealing lip 5 ensures the sealing and aesthetics of the joint surface.

[0023] A vent hole 6 with a diameter less than 1 mm is also provided at the top of one end of the retractable corrugated connecting tube 2 extending into the collecting cup 3; when negative pressure suction is performed, the vent hole 6 ensures the fluidity of air on both sides of the retractable connecting tube, achieves pressure balance, and prevents the retractable connecting tube from collapsing to the left.

[0024] The method of using the milk leakage sample extractor in the present invention is as follows:

[0025] Cover the breast shield 1 on the outside of the patient's breast, and the sampling technician / doctor collects the overflow sample by connecting the syringe and sucking negative pressure. After the sample is successfully collected, the overflow specimen flows to the cup below the collection cup, and then flows into the syringe. The sampling technician / doctor pulls out the syringe to perform a smear operation. If the negative pressure suction fails to successfully suck out the overflow, the sampling technician / doctor can pull open the retractable corrugated connecting tube 2, squeeze the nipple and areola, and take non-contact manual samples. After squeezing out the overflow, the syringe collects cells for smearing.

[0026] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
