Description

TECHNICAL FIELD

[0001] The utility model relates to a breast postoperative precision drainage device belongs to the medical instrument technical field. BACKGROUND

[0002] At present, there is no precision drainage device for breast postoperative patients, and subcutaneous hydrops and flap necrosis caused by measurement error still occur, which seriously affects the prognosis and satisfaction of patients.

[0003] At present, the drainage tube of the wound after clinical surgery is measured by pouring, and self-made containers such as air needle suction method or plugging the nipple below the air needle are used. There is a lack of convenient and accurate measuring tools on the market. These methods have the following problems: 1. The air needle suction method needs to prepare a disposable medicine bowl additionally. In order to ensure the hospital infection control principle, one bowl and one air needle are used by one person, which wastes consumables. 2. The air needle and the measuring cup are commonly used in clinical measurement. The capacity of the 20ml air needle is less than the maximum capacity of the negative pressure drainage device, which needs to be poured repeatedly and consumes manpower. The volume of the measuring cup is 1000ml, which is the common drainage volume of breast postoperative patients, and it cannot provide accurate measurement. 3. Repeatedly pouring cannot achieve accurate measurement, and cannot provide accurate indications for breast postoperative tube removal, which affects the prognosis of the disease. 4. When providing the air needle for the patient to use after discharge, the needle cannot be recycled, and medical waste cannot be classified. 5. Some patients lack nursing related professional knowledge and cannot use the air needle correctly, which causes liquid spilling or incomplete suction and leads to measurement error. 6.

[0023] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] A device for precise measurement of drainage after breast surgery, such as Figures 1-2 As shown, the device includes a pyramidal measuring cylinder 1. The pyramidal measuring cylinder 1 is a triangular pyramid, narrower at the bottom and wider at the top, made of plastic, with a capacity of 100ml. This 100ml volume is suitable for the 24-hour drainage volume of most post-mastectonic breast cancer patients, avoiding repeated emptying. One of the conical surfaces of the pyramidal measuring cylinder 1 is a graduated surface with graduations of 10, 20, 30, 40...100, i.e., 10 large divisions, each 10ml being one large division. For volumes below 30ml, each large division has five smaller divisions (the smallest graduation is 2ml), and for volumes above 30ml, each large division has two smaller divisions (the smallest graduation is 5ml), facilitating accurate measurement. The pyramidal design of the measuring cylinder 1, narrower at the bottom and wider at the top, combined with the graduations at different heights, makes it easy to see and accurately measure drainage volumes, regardless of the amount.

[0026] Furthermore, a red mark is placed above the highest graduation line of the pyramidal measuring cylinder 1 indicating that patients can come to the hospital for tube removal only if their blood volume is less than 10 ml for 3 consecutive days. The 10 ml graduation line on the pyramidal measuring cylinder 1 is also marked in bold red for easy reading by the patient.

[0027] The scale is located on the central axis of one of the conical surfaces (scale surfaces) of the pyramidal measuring cylinder 1. This scale surface is also equipped with a magnifying glass 3 for convenient and accurate reading. The magnifying glass 3 is slidably mounted on the scale surface. Specifically, refer to... Figure 2 As shown, slide rails 3-1 are provided on both sides of the scale, and the magnifying glass 3 is provided with corresponding grooves. Figure 2 (Not shown in the image) It can be installed on a slide rail and slide up and down. The slide rail 3-1 can be made of plastic, rubber or silicone or other materials. Furthermore, the magnifying glass 3 is provided with a limiting buckle 3-2. The limiting buckle 3-2 is rotatably installed on one side edge of the magnifying glass. The limiting buckle 3-2 can also be made of plastic, rubber or silicone or other materials. When the magnifying glass 3-2 slides to the vicinity of the liquid level scale, the limiting buckle 3-2 can be rotated to lock onto the scale surface, which can limit the magnifying glass 3 and prevent it from sliding and affecting the reading. When it is necessary to slide the magnifying glass up and down, the limiting buckle can be rotated to release the limitation.

[0028] The pyramidal measuring cylinder 1 has a bevel opening 2, that is, the opening end face is a bevel with one end higher and the other end lower, so that the patient can easily pour the negative pressure drainage device against the higher end to prevent blood from splashing out. The end face of the bevel opening 2 is an oval section or the corners of the bevel opening are rounded to avoid the potential risk of injury to the patient when using the opening with sharp corners.

[0029] The bottom of the pyramidal measuring cylinder 1 is provided with a base 4, which is circular, square or polygonal, and the area of the base 4 is larger than the area of the bottom of the pyramidal measuring cylinder 1, so as to increase the stability of the measuring cylinder and allow the measuring cylinder to be placed on a table to observe the drainage volume, greatly reducing the risk of spilling the drainage liquid.

[0030] In addition, the drainage device also includes two cards attached with the package, each card can record the drainage volume and time for 10 days, which is convenient for the patient to record and can provide the doctor with a more intuitive observation of the drainage condition when the tube is pulled out.

[0031] The back of the card is provided with a two-dimensional code information layer, and the two-dimensional code information layer is provided with three two-dimensional codes, which are: a drainage liquid measuring method demonstration, a breast cancer postoperative functional exercise method, and a breast cancer postoperative lymphedema prevention related video, providing health guidance for the patient to provide related nursing knowledge after discharge, and providing continuous nursing care.

[0032] The use method of the above drainage device is as follows:

[0033] Open the negative pressure drainage device and slightly tilt it against the higher end of the bevel opening of the pyramidal measuring cylinder 1 to slowly pour the liquid, place the device on a flat table, observe the drainage liquid scale, and record the date, time and volume on the card. Slowly pour the liquid along the higher end of the opening, clean and rinse the device, place it in a well-ventilated place to dry for next use. When the tube is pulled out, take the card to the hospital to provide the doctor with use.

[0034] The above implementation cases are only preferred implementation cases of the present application, and are not any form or substantial limitation of the present application. It should be noted that, for ordinary skilled persons in the technical field, without departing from the present application, a number of improvements and supplements can be made, which should also be regarded as the protection range of the present application.
