Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an infusion device with V-shaped exhaust and no bubble residue. Background Art

[0002] An infusion set is a medical device used to give patients infusions, that is, a device that delivers drugs, liquid nutrient solutions or other therapeutic fluids into the patient's body. Infusion sets are widely used in hospitals, clinics, and home care settings, and are a common medical device. Traditional infusion sets have puncture- and medication-adding injection parts that are mostly set on the Maupi drip chamber. The national standard GB8368-2018 will be implemented in 2021. The standard requires that the injection parts must be set at the end of the infusion set pipeline. Currently, the common injection parts at the end of the infusion set on the market are all Y-shaped structures. When the infusion set is vented, a section of air will remain in the inner cavity of the injection part. When it is shaken or medicated, air can easily enter the pipeline, forming a gas-liquid mixed bubble, and then be introduced into the human body to cause air embolism, endangering human health.

[0003] Therefore, an infusion device has been developed that can infuse liquid in a V-shaped manner, prevent air from remaining in the middle tube, avoid air from entering the patient's body during infusion, and ensure the safety of the patient with V-shaped exhaust and no residual bubbles. Utility Model Content

[0004] In order to overcome the disadvantage that the injection piece at the end of the existing infusion set is in the shape of a Y-shaped structure, and when it is shaken or dosed, air can easily enter the pipeline and be injected into the human body to cause air embolism, which is harmful to human health, the utility model provides an infusion device that can take in liquid in a V-shaped manner, prevent air from remaining in the middle tube, avoid air from entering the patient's body during infusion, and ensure the safety of the patient with V-shaped exhaust and no residual bubbles.

[0008] Further description, it also includes a sliding ring, an inclined rod and a clamping arm. The sliding ring is slidably connected to the middle tube, and a plurality of inclined rods are slidably connected to the sliding ring. The lower sides of the inclined rods are all connected to the clamping arms.

[0009] Further description, it also includes a heat preservation cover, a heater, a heat conduction pipe and a hand-held piece. The hand-held piece is connected to the right side of the middle part of the middle tube, the front and back sides of the hand-held piece are connected to the heat preservation cover, the upper left part of the middle tube is connected to the heater, the lower side of the heater is connected to the heat conduction pipe, the heat conduction pipe passes through the hand-held piece, and the heat conduction pipe is located between the heat preservation cover and the middle tube.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] A V-shaped exhaust and no bubble residue infusion device, such as Figure 1 and Figure 2 As shown, it includes a liquid inlet channel 1, an upper cover 2, a middle tube 3 and a liquid outlet channel 4. The right side of the middle tube 3 is connected to the liquid inlet channel 1, the upper side of the middle tube 3 is connected to the upper cover 2, and the lower part of the middle tube 3 is connected to the liquid outlet channel 4.

[0019] like Figure 1 and Figure 2 As shown, it also includes a detachable observation dust cover 5 and a lens 6. The detachable observation dust cover 5 is clamped on the upper part of the upper cover 2, and the lens 6 is connected to the detachable observation dust cover 5.

[0020] like Figure 1 and Figure 3 As shown, a spring 7 and a protective cover 8 are also included. The protective cover 8 is slidably connected to the liquid inlet channel 1, and the spring 7 is connected between the front and rear parts of the protective cover 8 and the middle tube 3.

[0021] like Figure 1 and Figure 3 As shown, it also includes a sliding ring 9, an inclined rod 10 and a clamping arm 11. The sliding ring 9 is slidably connected to the middle cylinder 3, and three inclined rods 10 are slidably connected to the sliding ring 9. The lower sides of the inclined rods 10 are all connected to the clamping arms 11.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a heat preservation cover 12, a heater 13, a heat conduction pipe 14 and a hand-held piece 15. The hand-held piece 15 is connected to the right side of the middle of the middle tube 3, and the heat preservation cover 12 is connected to the front and rear sides of the hand-held piece 15. The heater 13 is connected to the left side of the upper part of the middle tube 3, and the heat conduction pipe 14 is connected to the lower side of the heater 13. The heat conduction pipe 14 passes through the hand-held piece 15, and the heat conduction pipe 14 is located between the heat preservation cover 12 and the middle tube 3.

[0023] like Figure 2 As shown, it also includes a first partition plate 16 and a second partition plate 17. The first partition plate 16 is rotatably connected to the upper part of the middle tube 3. The second partition plate 17 is also rotatably connected to the upper part of the middle tube 3. The second partition plate 17 is located on the upper left of the first partition plate 16.

[0024] When using the utility model, first pull open the protective cover 8 on the liquid inlet channel 1, stretch the spring 7, and then connect the liquid inlet channel 1 with the upstream infusion hose, and then connect the liquid outlet channel 4 with the downstream infusion hose. The connection between the liquid inlet channel 1 and the middle cylinder 3 is a V-shaped structure. The liquid inlet channel 1 and the middle cylinder 3 are connected in series to form a liquid channel without dead angles. After the connection is completed, the injection liquid passes through the liquid inlet channel 1 and enters between the first partition 16 and the second partition 17. The liquid flow is blocked by the first partition 16 and changes its flow direction. After the injection liquid completely fills the V-shaped groove, it flows out of the V-shaped groove from the second partition 17. Due to the tension of the liquid, the injection liquid fills the upper space of the middle cylinder 3 to prevent the formation of residual air in the dead angle. Then it flows from the middle cylinder 3 into the liquid outlet channel 4, which can effectively discharge the air in each channel, thereby playing a role. The liquid can be introduced in a V-shaped manner to prevent air from remaining in the middle tube 3, and to prevent air from entering the patient's body during the infusion, thereby ensuring the safety of the patient. During the infusion, the infusion situation can be observed through the lens 6 of the detachable observation dust cover 5. When liquid addition is needed, the detachable observation dust cover 5 is removed, and liquid is added to the middle tube 3 from the upper cover 2. During the infusion, the sliding ring 9 slides downward on the inclined rod 10, so that the clamping arm 11 on the inclined rod 10 is squeezed and tightened, and the downstream infusion hose on the liquid outlet pipe is clamped to prevent the downstream infusion hose from shaking during the infusion. During the infusion process, the heater 13 is started to heat the heat conducting tube 14, and then the patient's hand is held on the heat preservation cover 12 on the handheld piece 15 to heat the injection liquid and the patient's hand, thereby reducing the patient's discomfort during the infusion.
