Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a sealing device for an injection tray of an infusion tube. Background Art

[0002] An infusion set is a common medical consumable, which is aseptically processed to establish a channel between a vein and a medicinal solution for intravenous infusion. Generally, it is composed of eight parts connected together, namely a venous needle or an injection needle, a needle cap, an infusion hose, a medicinal solution filter, a flow rate regulator, a drip chamber, a bottle stopper puncture device, and an air filter. Some infusion sets also have an injection tray. Under the action of atmospheric pressure, the liquid in the bottle flows into the drip chamber along the thinner infusion hose. When the water column pressure in the drip chamber is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.

[0003] During the infusion process, an injection tray is often needed to add medicine. A rubber stopper is arranged on the injection tray. During use, the needle of a syringe is inserted into the rubber stopper, and then the syringe is used to add medicine.

[0004] However, during actual use, in order to prevent external bacteria from entering the infusion tube, before inserting the needle into the rubber stopper of the injection tray, it is necessary to disinfect the rubber stopper with iodine solution. This requires medical staff to carry iodine solution and perform corresponding disinfection work before each medicine addition, which is cumbersome and inconvenient to use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sealing device for an injection tray of an infusion tube, which is used to solve the problem of troublesome use caused by the structural defects of the existing infusion tube.

[0006] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A sealing device for an injection tray of an infusion tube includes an injection tray body. A rubber stopper is fixedly arranged on the injection tray body. A sealing cover covering the rubber stopper is installed on the injection tray body. A sponge pad for soaking iodine solution is arranged in the sealing cover. When the sealing cover is covered on the injection tray body, the free end of the sponge pad abuts against the rubber stopper.

[0008] Further limited, a hinge structure is arranged between the injection tray body and the sealing cover, and the injection tray body and the sealing cover are hinged through the hinge structure. With such a structural design, by connecting the injection tray body and the sealing cover through the hinge structure, after the sealing cover is opened, the sealing cover is still connected to the injection tray body, eliminating the need to find another place to place the sealing cover and avoiding the risk of losing the sealing cover, making it more convenient to use.

[0009] It is further defined that the hinge structure includes a hinge rod and a hinge arm, the hinge rod is fixedly arranged on the injection plate body, the hinge arm is fixedly arranged on the sealing cover, and the hinge rod and the hinge arm are hinged. Such a structural design completes the hinge connection between the injection plate body and the sealing cover through the hinge connection between the hinge rod and the hinge arm, and has a simple structure and is easy to manufacture.

[0010] It is further defined that a torsion spring is provided between the hinge rod and the hinge arm, and a clamping structure is provided between the injection tray body and the sealing cover. With such a structural design, the torsion spring applies a restoring force to the connection between the injection tray body and the sealing cover, so that after the clamping structure releases the fixing of the sealing cover, the sealing cover can be automatically opened under the action of the torsion spring, which is more convenient to use.

[0011] It is further defined that the clamping structure includes a flip block and a clamping block, the flip block is fixedly provided with a hinge block on one side of the injection disk body close to the flip block, the flip block is hinged to the injection disk body through the hinge block, an elastic mechanism is installed between the flip block and the injection disk body below the hinge block, a limit block is fixedly provided on the upper end of the flip block close to one side of the injection disk body, the clamping block is fixedly set on the sealing cover, and when the sealing cover is covered on the injection disk body, the lower end face of the limit block rests on the upper end face of the clamping block. With this structural design, the flip block is pushed by the elastic mechanism so that the flip block has a tendency to rotate clockwise around the hinge block. When the sealing cover is placed on the injection disk body, the lower end surface of the limit block abuts against the upper end surface of the clamping block to complete the clamping of the sealing cover. When the sealing cover needs to be opened, it is only necessary to press the lower end of the flip block to overcome the prestress of the elastic mechanism so that the flip block rotates counterclockwise along the hinge block, so that the limit block can be freed from the restriction of the clamping block. At this time, the sealing cover can be automatically opened under the action of the torsion spring. The structure is simple and easy to use.

[0012] It is further defined that the elastic mechanism is a U-shaped spring. Such a structural design is simple in structure and easy to install.

[0013] It is further defined that the upper part of the flip block close to the injection disk body is a plane, and before the flip block is pressed, the plane is against the side wall of the injection disk body. Such a structural design limits the maximum clockwise rotation angle of the flip block under the action of the elastic mechanism through the plane of the flip block, thereby avoiding the problem of affecting the sealing cover to cover the injection disk body again due to excessive rotation of the flip block, and has strong practicality.

[0014] Further defined, a dovetail groove is vertically formed on the side of the flipping block away from the hinge block. A dovetail block is slidably installed in the dovetail groove. A locking plate is fixedly connected to the dovetail block. A stop block is fixedly provided on the injection disc body below the flipping block. With such a structural design, through the mutual cooperation of the locking plate and the stop block, when the injection disc is not in use, the locking plate can be slid downward relative to the flipping block so that the locking plate is located outside the stop block. At this time, the stop block limits the flipping of the locking plate. In this case, the flipping block cannot rotate counterclockwise around the hinge block, thus avoiding the problem that the sealing cover is accidentally opened due to accidental contact with the flipping block, and the practicability is relatively strong.

[0015] Further defined, a mounting seat is fixedly provided on the injection disc body. The flipping block, the locking plate and the stop block are all located in the mounting seat. A limiting strip is fixedly provided on the locking plate below the flipping block. With such a structural design, the maximum distance of the downward movement of the locking plate is limited by the mounting seat, and the maximum distance of the upward movement of the locking plate is limited by the limiting strip, avoiding the problem that the locking plate falls off due to excessive sliding when the locking plate is slid, and the practicability is relatively strong.

[0016] The utility model adopting the above technical solution has the following advantages:

[0017] 1. The sponge pad contaminated with iodine solution is carried by the sealing cover, and the rubber plug of the injection disc body is covered by the sealing cover, avoiding the end of the rubber plug from contacting the outside air when not in use. The rubber plug is disinfected by the sponge pad contaminated with iodine solution pressing against it. While further avoiding the pollution of the rubber plug, when adding medicine is needed, there is no need to separately carry iodine solution to disinfect the rubber plug of the injection disc body, and the use is more convenient;

[0018] 2. The injection disc body and the sealing cover are connected by a hinge structure, so that after the sealing cover is opened, the sealing cover is still connected to the injection disc body, and there is no need to find another place to place the sealing cover, avoiding the risk of losing the sealing cover, and the use is more convenient;

[0019] 3. A restoring force is applied to the connection between the injection disc body and the sealing cover by a torsion spring, so that after the clamping structure releases the fixation of the sealing cover, the sealing cover can be automatically opened under the action of the torsion spring, and the use is more convenient;

[0020] 4. Through the pushing of the flipping block by the elastic mechanism, the flipping block has a tendency to rotate clockwise around the hinged block. When the sealing cover is set on the injection disc body, the lower end surface of the limiting block abuts against the upper end surface of the clamping block to complete the clamping of the sealing cover. When it is necessary to open the sealing cover, just press the lower end of the flipping block to overcome the prestress of the elastic mechanism, so that the flipping block rotates counterclockwise along the hinged block, and then the limiting block can be disengaged from the restriction of the clamping block. At this time, the sealing cover can be automatically opened under the action of the torsion spring. The structure is simple and easy to use;

[0021] 5. Through the mutual cooperation of the locking plate and the stopper, when the injection disc is not in use, the locking plate can be slid downward relative to the flipping block so that the locking plate is located outside the stopper. At this time, the flipping of the locking plate is limited by the stopper. In this case, the flipping block cannot rotate counterclockwise around the hinged block, thereby avoiding the problem of accidental opening of the sealing cover caused by accidentally touching the flipping block, and the practicability is strong.

[0038] As Figures 1 to 8 shown, a sealing device for an injection tray of an infusion tube according to the present utility model includes an injection tray body 1, a rubber stopper 10 fixedly provided on the injection tray body 1, a sealing cover 2 mounted on the injection tray body 1 to cover the rubber stopper 10, a sponge pad 3 for soaking iodine solution provided in the sealing cover 2, and when the sealing cover 2 is covered on the injection tray body 1, the free end of the sponge pad 3 abuts against the rubber stopper 10.

[0039] An articulated structure is provided between the injection tray body 1 and the sealing cover 2, and the injection tray body 1 and the sealing cover 2 are articulated through the articulated structure. By connecting the injection tray body 1 and the sealing cover 2 through the articulated structure, after the sealing cover 2 is opened, the sealing cover 2 is still connected to the injection tray body 1, eliminating the need to find another place to place the sealing cover 2 and avoiding the risk of losing the sealing cover 2, making it more convenient to use.

[0040] The articulated structure includes an articulated rod 11 and an articulated arm 21. The articulated rod 11 is fixedly provided on the injection tray body 1, the articulated arm 21 is fixedly provided on the sealing cover 2, and the articulated rod 11 is articulated with the articulated arm 21. Through the articulation of the articulated rod 11 and the articulated arm 21, the articulation of the injection tray body 1 and the sealing cover 2 is completed, with a simple structure and convenient manufacturing.

[0041] A torsion spring 110 is provided between the articulated rod 11 and the articulated arm 21, and a clamping structure is provided between the injection disc body 1 and the sealing cover 2. The torsion spring 110 applies a restoring force to the connection between the injection disc body 1 and the sealing cover 2, so that after the clamping structure releases the fixation of the sealing cover 2, the sealing cover 2 can be automatically opened under the action of the torsion spring 110, making it more convenient to use.

[0042] The clamping structure includes a flipping block 4 and a clamping block 40. A hinge block 41 is fixedly provided on one side of the flipping block 4 close to the injection disc body 1. The flipping block 4 is hinged to the injection disc body 1 through the hinge block 41. An elastic mechanism 42 is installed between the flipping block 4 and the injection disc body 1 below the hinge block 41. A limiting block 43 is fixedly provided on one side of the upper end of the flipping block 4 close to the injection disc body 1. The clamping block 40 is fixedly arranged on the sealing cover 2. When the sealing cover 2 is covered on the injection disc body 1, the lower end surface of the limiting block 43 abuts against the upper end surface of the clamping block 40. Through the pushing of the elastic mechanism 42 on the flipping block 4, the flipping block 4 has a tendency to rotate clockwise around the hinge block 41. When the sealing cover 2 is covered on the injection disc body 1, the lower end surface of the limiting block 43 abuts against the upper end surface of the clamping block 40 to complete the clamping of the sealing cover 2; when it is necessary to open the sealing cover 2, only need to press the lower end of the flipping block 4 to overcome the prestress of the elastic mechanism 42, so that the flipping block 4 rotates counterclockwise along the hinge block 41, then the limiting block 43 can be separated from the restriction of the clamping block 40. At this time, the sealing cover 2 can be automatically opened under the action of the torsion spring 110. The structure is simple and the use is convenient.

[0043] The elastic mechanism 42 is a U-shaped spring. The structure is simple and the installation is convenient.

[0044] The upper part of one side of the flipping block 4 close to the injection disc body 1 is a plane. Before pressing the flipping block 4, the plane abuts against the side wall of the injection disc body 1. Through the plane of the flipping block 4, the maximum clockwise rotation angle of the flipping block 4 under the action of the elastic mechanism 42 is limited, avoiding the problem that the flipping block 4 rotates excessively and affects the re-covering of the sealing cover 2 on the injection disc body 1. The practicability is strong.

[0045] A dovetail groove 44 is vertically opened on one side of the flipping block 4 away from the hinge block 41. A dovetail block is slidably installed in the dovetail groove 44, and a locking plate 5 is fixedly connected to the dovetail block. A stop block 51 is fixedly provided on the injection disc body 1 below the flipping block 4. Through the mutual cooperation of the locking plate 5 and the stop block 51, when the injection disc is not in use, the locking plate 5 can be slid downward relative to the flipping block 4 so that the locking plate 5 is located outside the stop block 51. At this time, the stop block 51 limits the flipping of the locking plate 5. In this case, the flipping block 4 cannot rotate counterclockwise around the hinge block 41, thereby avoiding the problem that the sealing cover 2 is accidentally opened due to accidental contact with the flipping block 4. The practicability is strong.

[0046] A mounting seat 52 is fixedly provided on the injection tray body 1, and the flip block 4, the locking plate 5 and the stopper 51 are all located in the mounting seat 52. A limit strip 53 is fixedly provided on the locking plate 5 below the flip block 4. The mounting seat 52 limits the maximum distance of the locking plate 5 moving downward, and the limit strip 53 limits the maximum distance of the locking plate 5 moving upward, so as to avoid the problem of the locking plate 5 falling off due to excessive sliding when the locking plate 5 is slid, and the practicability is strong.

[0047] In this embodiment, when it is necessary to add medicine through the injection disk, the locking plate 5 is pushed upward so that the locking plate 5 is offset from the stopper 51 until the limit bar 53 abuts against the lower end surface of the flip block 4 (such as Figure 1 and Figure 2 shown);

[0048] The lower end of the locking plate 5 is pressed to overcome the prestress of the U-shaped spring, so that the flip block 4 rotates counterclockwise around the hinge block 41, so that the limit block 43 is free from the restriction on the clamping block 40. At this time, the sealing cover 2 can be automatically opened under the action of the torsion spring 110 (such as Figure 7 As shown), at this time, the medicine can be added from the rubber stopper 10 of the injection plate body 1 through a syringe with a needle;

[0049] After the addition of medicine is completed, the needle is pulled out and the sealing cover 2 is turned over so that the sealing cover 2 is re-covered on the injection disk body 1, and the flip block 4 is pushed by the clamping block 40 to rotate counterclockwise again until the lower end surface of the limit block 43 is against the upper end surface of the clamping block 40, thereby completing the resealing and disinfection of the injection disk body 1.
