Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a disposable sterile adjustable negative pressure suction tube. Background Art

[0002] Disposable sterile medical suction tubes are mainly used to absorb body fluids, secretions and other substances to help clear the respiratory or digestive tract. They are widely used in medical treatment, surgery, nursing and other fields to prevent cross infection and ensure patient safety.

[0003] The existing disposable sterile medical suction tube is inserted into the patient's body by medical staff, and the other end is connected to the suction device to generate negative pressure in the suction tube to suck out the body fluids in the patient's body. However, when the medical staff controls the negative pressure in the suction tube, they need to hold the suction tube with one hand and control the suction device with the other hand, which is inconvenient to operate.

[0004] Therefore, a disposable sterile adjustable negative pressure suction tube has been developed that can control the negative pressure in the tube by pedaling, thereby improving the convenience of operation for medical staff. Utility Model Content

[0006] The technical solution is: a disposable sterile adjustable negative pressure suction tube, comprising a first connecting tube, a second connecting tube, a connecting piece, a protective mechanism and a negative pressure mechanism, the second connecting tube is provided on the right part of the first connecting tube, the connecting piece is connected to the right side of the second connecting tube, the protective mechanism with a protective function is provided between the first connecting tube and the second connecting tube, and the negative pressure mechanism capable of controlling the negative pressure in the first connecting tube is provided on the protective mechanism.

[0007] Furthermore, the protection mechanism includes a base frame, an outer shell, a first spring and a top block, the base frame is arranged between the first connecting tube and the second connecting tube, the outer shell is rotatably connected to the rear of the base frame, the first spring is connected to the upper rear side of the base frame, and the top block is connected to the lower rear side of the outer shell, the connection between the first connecting tube and the second connecting tube is placed between the base frame and the outer shell, and then the outer shell is stepped on to rotate downward and close with the base frame, and the top block squeezes the first spring to contract.

[0008] Furthermore, it also includes the negative pressure mechanism, which includes a sleeve, an access tube, a limiting frame, a second spring and a locking piece. The sleeve is provided at the front of the base frame, and the access tubes are connected to the left and right sides of the sleeve. The access tube on the left side is clamped with the first connecting tube, and the access tube on the right side is clamped with the second connecting tube. The limiting frame is slidably connected to the upper part of the sleeve, and the access tubes are in contact with the limiting frame. The second spring is connected between the limiting frame and the sleeve, and the locking piece is connected to the upper side of the front of the base frame, and the locking piece is clamped with the sleeve. Stepping on the shell rotates downward, pushes the limiting frame to move downward on the sleeve, and the second spring contracts, so that the limiting frame is separated from the access tube, and the first connecting tube is connected to the second connecting tube.

[0009] Furthermore, the connecting piece is a telescopic structure.

[0010] Furthermore, the shell is provided with anti-slip grooves.

[0011] Furthermore, a sealing gasket is provided on the limiting frame.

[0012] Compared with the prior art, the utility model has the following advantages: 1.

DETAILED DESCRIPTION

[0020] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] A disposable sterile adjustable negative pressure suction tube, such as Figure 1-Figure 3 As shown, it includes a first connecting tube 1, a second connecting tube 2, a connecting piece 3, a protection mechanism 4 and a negative pressure mechanism 5. The second connecting tube 2 is provided on the right side of the first connecting tube 1, and the connecting piece 3 is connected to the right side of the second connecting tube 2. The connecting piece 3 is a telescopic structure for easy adjustment. The protection mechanism 4 is provided between the first connecting tube 1 and the second connecting tube 2, and the negative pressure mechanism 5 is provided on the protection mechanism 4.

[0022] like Figure 1-Figure 4 As shown, the protection mechanism 4 includes a base frame 41, an outer shell 42, a first spring 43 and a top block 44. The base frame 41 is arranged between the first connecting tube 1 and the second connecting tube 2. The outer shell 42 is rotatably connected to the rear of the base frame 41. The outer shell 42 is provided with anti-slip grooves for easy stepping. The first spring 43 is connected to the upper rear side of the base frame 41, and the top block 44 is connected to the lower rear side of the outer shell 42.

[0023] When using the utility model, firstly, the first connecting tube 1 and the second connecting tube 2 are docked, and then the connecting piece 3 is connected to the suction device, and then the end of the first connecting tube 1 is placed at the position where the patient needs to be suctioned, and the suction device is started to generate negative pressure in the first connecting tube 1, so that the first connecting tube 1 sucks out the liquid in the patient's body. After the first connecting tube 1 and the second connecting tube 2 are docked, the connection between the first connecting tube 1 and the second connecting tube 2 can be placed between the base frame 41 and the shell 42, and then the shell 42 is stepped on to rotate the shell 42 downward and close with the base frame 41, and the top block 44 squeezes the first spring 43 to contract, thereby protecting the connection between the first connecting tube 1 and the second connecting tube 2 and preventing the connection between the first connecting tube 1 and the second connecting tube 2 from being disconnected.

[0024] like Figure 1-Figure 5As shown, it also includes the negative pressure mechanism 5, which includes a sleeve 51, an access tube 52, a limiting frame 53, a second spring 54 and a retaining member 55. The sleeve 51 is provided at the front of the base frame 41, and the access tube 52 is connected to the left and right sides of the sleeve 51. The access tube 52 on the left side is clamped with the first connecting tube 1, and the access tube 52 on the right side is clamped with the second connecting tube 2. The upper part of the sleeve 51 is slidably connected with the limiting frame 53, and a sealing gasket is provided on the limiting frame 53 for easy sealing. The access tubes 52 are all in contact with the limiting frame 53, and the second spring 54 is connected between the limiting frame 53 and the sleeve 51. The retaining member 55 is connected to the upper side of the front of the base frame 41, and the retaining member 55 is clamped with the sleeve 51.

[0025] The negative pressure mechanism 5 of the present device can be used to control the negative pressure in the first connecting tube 1. The sleeve 51 is engaged with the locking member 55 so that the sleeve 51 is fixed on the base frame 41. The first connecting tube 1 and the second connecting tube 2 are engaged with the access tube 52 respectively. When the patient's body fluid is sucked, the shell 42 is stepped on to rotate downward, and the limiting frame 53 is pushed to move downward on the sleeve 51. The second spring 54 contracts, so that the limiting frame 53 is separated from the access tube 52, and the first connecting tube 1 is connected to the second connecting tube 2. When the negative pressure in the first connecting tube 1 needs to be blocked, the first spring 43 rebounds to push the shell 42 to rotate upward and reset. Then, the second spring 54 rebounds to drive the limiting frame 53 to reset, and the access tube 52 is closed, thereby playing the role of being able to control the negative pressure in the tube by stepping, thereby improving the convenience of operation for medical staff.
