Problems solved by technology

This routine has the following defects: 1. Since the patient's sputum is directly mixed into the sputum bucket every time, it is impossible to observe the properties of the sputum in time and accurately during the operation; Replacement of the sputum suction line with the sample bottle will complicate the entire sputum suction process; 3. Since the sputum may overflow from the negative pressure control switch (6) during suction, the operator needs to wear sterile gloves for protection. Sputum suction requires a certain period of time to change gloves, and when the patient encounters a sudden gushing of sputum during first aid, it is easy to delay the timing of treatment and cause the patient's condition to deteriorate; 4. After the sputum suction is completed, the sputum storage bottle (8) needs to be cleaned and disinfected ; 5. Microorganisms in the sputum storage bottle (8) are easy to multiply, and there is a risk of polluting the negative pressure source with the air flow

Embodiment 1

[0013] Such as figure 2 As shown, the sputum suction pipeline (1) is formed by extrusion process of medical polyvinyl chloride, the inner hole diameter is 4 mm, the outer diameter is 6 mm, and the length is 500 mm; the transition connection part (2) is made of harder medical polyvinyl chloride Through injection molding into a T-shaped appearance, the connection part (2-1) of the suction pipe (2-1) is glued together with the suction pipe (1), and the internal suction pipe-sputum storage bag passage (2-4) enters the sputum storage The part (2-6) in the bag (3) has a length of 30 mm; the negative pressure passage-sputum storage bag passage (2-5) is built with a sponge block (2-7), and the negative pressure passage-sputum storage bag passage enters the sputum storage The partial length of the bag is 5 mm; the sputum storage bag (3) is a soft film bag-like structure with an open end and a hollow interior, made of transparent polyvinyl chloride or polypropylene film with a thicknes...

Embodiment 2

[0018] Such as image 3 , 4 , 5, the shell (4) is a split design, composed of two almost symmetrical parts, the shape is easy to hold, and it is injection molded with transparent materials such as polycarbonate, polystyrene, etc. The shell (4) is at least One part has a dimple (4-3) for accommodating the transitional connection part (2) and a dimple (4-4) for accommodating the sputum storage bag (3), and the two parts of the housing (4) can also be provided with depressions, which can be combined into a cavity; the negative pressure passage (5) can be accommodated in the housing (4) or formed by the airtight combination of the depressions made on the two parts of the housing; the internal cavity or passage formed by the combination is to strengthen the sealing effect , sealing strips (4-5) etc. can be added or embedded in the edge of the matching part; hinges can be set at the joint of the two parts of the shell (4) to ensure the stability during the opening and closing proce...

Abstract

The invention discloses a double-negative pressure sputum aspiration device, comprising a sputum aspiration pipeline (1), a transitional connection component (2), a sputum storage bag (3), a shell (4) and a negative pressure channel (5), wherein the sputum storage bag (3) is connected with the negative pressure channel (5) through the transitional connection component (2) and the sputum aspiration pipeline (1), the sputum storage bag (3) is arranged inside the shell (4), and a gap (4-1) from the sputum storage bag (3) to the inner wall of the shell (4) is connected with the shell (4). In the device, based on the principle of double negative pressures, the soft and small sputum storage bag (3) is arranged inside the shell (4) to replace a hard and large sputum storage bottle (8), thereby overcoming the defects of traditional sputum aspiration device.

Description

technical field [0001] The invention relates to a double negative pressure sputum suction device, which belongs to the field of medical instruments. Background technique [0002] Sputum suction is a commonly used clinical treatment method. When there is an emergency situation such as a large amount of sputum, viscous, etc., if the sputum suction is not timely, the patient may suffocate or even die. The routine suction procedure with a negative pressure source is to connect the sputum storage bottle (8) to the negative pressure source connecting tube (7), and one end of the sputum suction line (1) is connected to the sputum storage bottle (8) through the intermediate connecting tube (9). ), the other end is inserted into the patient's trachea, and the sputum is sucked into the sputum storage bottle (8) step by step and mixed together. This routine has the following defects: 1. Since the patient's sputum is directly mixed into the sputum bucket every time, it is impossible to...
