Description

Technical Field

[0001] The utility model relates to the technical field of medical device fixing, in particular to a micro pump extension tube fixing device. Background Art

[0002] The micro-injection pump (micro-pump for short) is a new type of pumping instrument that can accurately, micro-amount, evenly and continuously output a small amount of fluid. It consists of a controller, an actuator and a syringe. The micro-injection pump accurately, micro-amounts, evenly and continuously pumps a small amount of liquid medicine into the body. It is easy to operate, timed and quantitative. The drug concentration and speed can be adjusted at any time according to the needs of the disease, so that the drug can maintain an effective blood drug concentration in the body. Using a micro-pump to rescue critically ill patients can reduce the workload of nurses, improve work efficiency, and accurately, safely and effectively cooperate with doctors in rescue.

[0003] Some patients have been using bedside micro-spring pumps for long-term medication. The syringe needs to draw out the drug before connecting to the extension tube. The connection often becomes detached due to movement or being touched carelessly, which can easily lead to blood backflow. If this happens at night and no one notices, it can cause the patient to lose too much blood in severe cases. Utility Model Content

[0004] The utility model aims to provide a micro pump extension tube fixing device to solve the problem that the existing extension tube is easy to fall off at the needle tube nipple.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a micro pump extension tube fixing device, comprising a shell and a collar, the bottom end of the shell is fixedly connected to a pair of symmetrical pull ropes, the free ends of the pair of pull ropes are commonly fixedly connected to a cylindrical hollow tube, the side wall of the hollow tube is provided with a plurality of annular grooves, the top end of the collar is fixedly connected to a pair of symmetrical connecting columns, and the top ends of the pair of connecting columns are provided with blocks that cooperate with the grooves.

[0006] Preferably, the side wall of the hollow cylinder is provided with a pair of symmetrical channels, and the block can pass through the channels.

[0007] Preferably, the connecting column is a spring sheet.

[0008] Preferably, the pull rope is an elastic rope or a tension spring.

[0009] Preferably, the cross section of the shell is in the shape of three quarters to one half of a circular ring.

[0010] Preferably, the top of the block and the top of the side wall of the slot are chamfered.

[0011] The principle and beneficial effects of this technical solution:

[0012] (1) The shell can be installed on the syringe, and the hollow tube can be sleeved on the syringe nipple. The position of the hollow tube can be fixed by the pulling force of the pull rope. When the extension tube is sleeved on the syringe nipple, the extension tube becomes larger due to the deformation area, and the ring is fixed at this position to jam the extension tube. The device is easy to install, the material is cheap and can be reused.

[0013] (2) When unloading and installing the card block and the card slot, it is inconvenient to punch the connecting column by hand. The channel design allows the ring to be rotated to realize the unloading and installation of the device, which is convenient for the user to operate BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 A schematic structural diagram of a micro pump extension tube fixing device provided by an embodiment of the utility model;

[0015] In the figure: 1, shell; 2, ring; 3, pull rope; 4, hollow cylinder; 5, slot; 6, connecting column; 7, block; 8, channel. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and implementation modes:

[0017] like Figure 1 A micro pump extension tube fixing device shown includes a housing 1 and a collar 2, wherein the cross section of the housing 1 is in the shape of a three-quarter to one-half circular ring, the housing 1 has an inner diameter slightly smaller than the outer diameter of the syringe, and the housing 1 material has a certain tension, which enables the housing 1 to be fixed on the syringe. A pair of symmetrical drawstrings 3 are fixedly connected to the bottom end of the housing 1, and the drawstrings 3 are elastic ropes or tension springs. The free ends of the pair of drawstrings 3 are fixedly connected to a cylindrical hollow cylinder 4, and the side wall of the hollow cylinder 4 is provided with a plurality of annular grooves 5. A pair of symmetrical connecting columns 6 are fixedly connected to the top of the collar 2, and the connecting columns 6 are spring sheets. A block 7 cooperating with the groove 5 is provided at the top of the pair of connecting columns 6. The inner diameter of the collar 2 is equal to or slightly larger than the outer diameter of the extension tube, and when the extension tube is sleeved on the syringe nipple, it will be deformed, and the area of ​​the connection becomes larger, and the collar 2 can be stuck at the enlarged area.

[0018] A pair of symmetrical channels 8 are formed on the side wall of the hollow cylinder 4, and the block 7 can pass through the channels 8. The top of the block 7 and the top of the side wall of the slot 5 are chamfered, and the collar 2 can be directly pushed upward during installation to achieve the locking of the collar 2 and complete the fixing of the device.

[0019] The specific implementation process is as follows:

[0020] The shell 1 can be stuck on the side wall of the syringe, and the hollow tube 4 is sleeved outside the syringe nipple, so that the pull rope 3 is stretched and the pull rope 3 will give the hollow tube 4 an upward force, which can fix the position of the hollow tube 4. The ring 2 is sleeved on the outside of the extension tube. When the extension tube is sleeved outside the syringe nipple, the ring 2 is moved. During the upward movement, the block 7 will be stuck in the groove 5 and fixed. At the same time, due to the area problem of the extension tube, the syringe nipple and the ring 2, the ring 2 can clamp the extension tube; when the device needs to be removed, the connecting column 6 can be moved to both sides to disengage the block 7 from the groove 5, and the block 7 can also be disengaged from the channel 8 by rotating the ring 2.

[0021] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical scheme or characteristics in the scheme is not described in detail here. For those skilled in the art, without departing from the technical scheme of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
