Description

Technical Field

[0001] The utility model relates to a portable drainage tube squeezing device, belonging to the technical field of medical instruments. Background Art

[0002] Drainage tubes are commonly used in modern medical procedures, draining fluids such as pus, blood, and exudate from surgical wounds. However, in clinical practice, thick fluids and tissue often clog the drainage tubes, causing blockages. This can hinder drainage, cause postoperative infections, and hinder wound healing.

[0003] When a drainage tube is blocked, it is currently usually handled by manually squeezing the local drainage tube. Squeezing the drainage tube can create negative pressure inside the drainage tube, thereby expelling the obstruction and unblocking the drainage tube. However, the current manual squeezing method is laborious to operate. Prolonged squeezing operation will not only cause friction damage to the skin of medical staff, but also easily damage the finger joints, posing a potential risk of occupational injury. In addition, manual squeezing is also prone to errors. At the very least, the unblocking effect is poor, and at worst, the tube may be accidentally expelled, affecting the patient's recovery. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a portable drainage tube squeezing device with an ingenious structure and reasonable design. The device can conveniently squeeze the drainage tube and saves effort in operation, which is beneficial for protecting medical staff from injury and protecting patients from the pain of accidental extubation.

[0005] According to the technical solution provided by this utility model:

[0006] A portable drainage tube squeezing device includes a lower clamping body, an upper clamping body and a torsion spring, wherein the torsion spring drives the front ends of the lower clamping body and the upper clamping body to close when not subject to external force; the device is characterized in that a squeezing platform is integrally provided at the bottom of the front end of the lower clamping body, and a tube-passing channel is provided between the squeezing platform and the front part of the upper clamping body for the drainage tube to pass through, a tube-squeezing mechanism is installed in the squeezing platform, and the tube-squeezing mechanism is connected to the front end of the upper clamping body, and when the front end of the upper clamping body opens and closes, the tube-squeezing mechanism is driven to squeeze the drainage tube back and forth.

[0007] As a further improvement of the present invention, the tube extrusion mechanism includes an extrusion wheel and a connecting fork arm. A sloped groove is provided on the inner wall beside the tube passage in the extrusion platform. The depth of the sloped groove gradually decreases from bottom to top. The extrusion wheel is movably embedded in the sloped groove. The extrusion wheel is installed in the lower fork of the connecting fork arm, and the upper end of the connecting fork arm is hinged to the upper clamping body.

[0008] As a further improvement of the present invention, a narrow tube placement slot is provided on the side of the extrusion platform and the front portion of the upper clamping body for the drainage tube to be squeezed in after being flattened. The width of the narrow tube placement slot is smaller than the outer diameter of the drainage tube.

[0009] As a further improvement of the present invention, the connecting fork arm is preferably made of elastic metal material.

[0010] As a further improvement of the present invention, the elastic metal material is titanium alloy.

[0011] As a further improvement of the present invention, an anti-slip friction ring is provided at the lower portion of the pipe passage in the extrusion platform.

[0012] As a further improvement of the present invention, the lower clamping body, the upper clamping body and the extrusion platform are made entirely of transparent material.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The utility model rationally utilizes the labor-saving characteristic of products with a clamping structure, and is cleverly designed on this basis. A squeezing platform is provided at the front end of the lower clamping body, a tube-threading channel is provided at the front of the squeezing platform and the upper clamping body, and a tube-squeezing mechanism connected to the upper clamping body is provided in the squeezing platform. The opening and closing of the front end of the upper clamping body drives the tube-squeezing mechanism to reciprocately squeeze the drainage tube, so that negative pressure is generated in the drainage tube, thereby discharging obstructions and unblocking the drainage tube. The utility model is very labor-saving during operation, which is beneficial to protecting medical staff from injury and protecting patients from the pain of accidental tube removal.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, Example 1 discloses a portable drainage tube extrusion device, which is mainly composed of components such as a lower clamp body 1, an upper clamp body 2, a torsion spring 3, an extrusion wheel 7 and a connecting fork arm 8. The lower clamp body 1, the upper clamp body 2 and the torsion spring 3 are installed in a conventional manner, and the torsion spring 3 drives the front ends of the lower clamp body 1 and the upper clamp body 2 to close when not subject to external force; a squeezing platform 4 is integrally provided at the bottom of the front end of the lower clamp body 1, and the front of the squeezing platform 4 and the upper clamp body 2 are provided with a pipe passage 5 that passes through the top and bottom for the drainage tube 9 to pass through; a section of a sloped surface groove 6 is opened on the inner wall of the side of the pipe passage 5 in the squeezing platform 4, and the depth of the sloped surface groove 6 gradually decreases from bottom to top, and the squeezing wheel 7 is movably embedded in the sloped surface groove 6, and the squeezing wheel 7 is installed in the lower fork of the connecting fork arm 8, and the upper end of the connecting fork arm 8 is hinged to the upper clamp body 2.

[0023] In specific applications, the drainage tube 9 is installed in the tube passage 5, and the extrusion wheel 7 is located next to the drainage tube 9. When the drainage tube 9 is unobstructed, the front ends of the lower clamp 1 and the upper clamp 2 are closed, and the extrusion wheel 7 is located at the widest part of the lower end of the slope surface groove 6, which will not generate pressure on the drainage tube 9. When the drainage tube 9 is blocked and needs to be squeezed and unblocked, it is only necessary to hold the rear ends of the lower clamp 1 and the upper clamp 2 and apply force to separate the front ends of the lower clamp 1 and the upper clamp 2. At this time, the connecting fork arm 8 will drive the extrusion wheel 7 to move upward along the slope surface groove 6. Since the depth of the slope surface groove 6 gradually decreases from bottom to top, the extrusion wheel 7 will generate an extrusion force on the adjacent drainage tube 9 during the upward movement, so that negative pressure is generated in the drainage tube 9. When the front ends of the lower clamping body 1 and the upper clamping body 2 are separated to the limit position and then released, the lower clamping body 1 and the upper clamping body 2 will be reset under the action of the torsion spring 3, and the extrusion wheel 7 will also be reset. This cycle will be repeated until the obstruction in the drainage tube 9 is discharged and the drainage tube 9 is unobstructed again.

[0024] In this embodiment 1, since the upper clamp body 2 is driving the connecting fork arm 8 to move up and down, the connecting fork arm 8 will also be subjected to a certain bending force. In order to ensure the structural strength of the product, the connecting fork arm 8 is preferably made of elastic metal material [such as the titanium alloy material used to make glasses legs on the market].

[0025] In this embodiment 1, the lower clamping body 1, the upper clamping body 2 and the extrusion platform 4 are preferably made of transparent materials as a whole, so that the extrusion of the drainage tube 9 can be observed intuitively.

[0026] Example 2

[0027] Example 2 discloses a portable drainage tube squeezing device. This device differs from the previous example in that the squeezing platform 4 and the side surfaces of the front portion of the upper clamping body 2 are provided with a narrow tube insertion slot 10 into which the drainage tube 9 is squeezed and flattened. The width of this slot 10 is smaller than the outer diameter of the drainage tube 9. This arrangement allows the device to be subsequently attached to the drainage tube 9 during use, making operation more convenient. The width of the slot 10 should be as small as possible, sufficient to allow the drainage tube 9 to be squeezed and flattened.

[0028] In addition, in this embodiment 2, an anti-slip friction ring 11 is provided at the lower portion of the pipe passage 5 in the extrusion platform 4, which can constrain the relative position of the utility model on the drainage tube 9 to a certain extent.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various variations and modifications are possible within the technical scope of the present invention. Any modifications, alterations, or equivalent substitutions made by a person skilled in the art based on the above description are considered to be within the scope of protection of the present invention.
