DETAILED DESCRIPTION

[0024] The following is a description of the embodiments, and further details are given of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0025] like Figure 1 As shown, a compression hemostasis device for intravenous infusion includes a hemostasis pressing part, both ends of the hemostasis pressing part are respectively fixedly connected with a strip elastic band 2, and the ends of the strip elastic band 2 away from the hemostasis pressing part are provided with quick connectors, and the strip elastic bands 2 on both sides of the hemostasis pressing part are detachably connected through the quick connectors. Specifically, the quick connector can be a nylon buckle assembly, that is, the end of the strip elastic band 2 on one side of the hemostasis pressing part away from the hemostasis pressing part is provided with a nylon male buckle, and the end of the strip elastic band 2 on the other side away from the hemostasis pressing part is correspondingly provided with a nylon female buckle.

[0026] The width of the strip elastic band 2 is preferably set to 3-4 cm, and the length can be set to 15 cm, 20 cm, 25 cm, etc. according to different pressing parts.

[0027] The hemostatic pressing part includes a support plate 1 and a pressing piece, the two ends of the support plate 1 are fixedly connected to the strip elastic bands 2 on both sides of the hemostatic pressing part, and supporting feet 3 are fixedly arranged on both sides of the lower side of the support plate 1. The pressing piece includes a pressing head 4 and a compression part 5, the pressing head 4 and the compression part 5 are respectively located above and below the support plate 1, at least one connecting rod 8 is arranged between the pressing head 4 and the compression part 5, and the two are fixedly connected as a whole through the connecting rod 8, a longitudinal through hole 1a is arranged on the support plate 1, the connecting rod 8 passes through the longitudinal through hole 1a of the support plate 1 and the two ends are respectively fixedly connected to the bottom of the pressing head 4 and the top of the compression part 5, the pressing piece can slide up and down relative to the support plate 1, and the pressing piece can be fixed in a high position or a low position. When the pressing piece is fixed in a high position, the lowest end of the compression part 5 is higher than the plane where the supporting feet 3 are located, and the compression part 5 does not press the patient. When the pressing piece is fixed in a low position, the lowest end of the compression part 5 is lower than the plane where the supporting feet 3 are located, and the compression part 5 presses the patient.

[0028] The hemostatic pressing part also includes a first return spring 7, the two ends of which respectively press against the top of the support plate 1 and the bottom of the pressing head 4. In the absence of external force, the first return spring 7 provides elastic force, and the elastic force is greater than the gravity of the pressing piece, thereby fixing the pressing piece in a high position.

[0029] Example 1

[0030] like Figures 2 to 4As shown, the hemostatic pressing part also includes a locking member, which includes a latch 9, wherein a one-way rack 8a is provided in the axial direction of one of the connecting rods 8, and a transverse through hole 1b is also provided on the support plate 1, wherein the transverse through hole 1b intersects with the longitudinal through hole 1a where the connecting rod 8 with the one-way rack 8a is located, and the latch 9 is sleeved in the transverse through hole 1b, and the head of the latch 9 extends into the longitudinal through hole 1a, and cooperates with the one-way rack 8a, thereby limiting the connecting rod 8 to only slide in one direction in the longitudinal through hole 1a, thereby limiting the pressing member to only move in one direction. Specifically, the moving direction of the pressing member is limited to moving from a high position to a low position, and the tail of the latch 9 is located outside the support plate 1. In order to facilitate operation, a gripping portion 9a is provided at the tail of the latch 9. The locking member also includes a second return spring 10, which is sleeved on the latch 9, and the two ends of the second return spring 10 are respectively fixedly connected to the support plate 1 and the gripping portion 9a, and the second return spring 10 provides a tensile elastic force, so that the head of the latch 9 remains inserted into the tooth groove of the one-way rack 8a in the absence of external force. When necessary, the gripping portion 9a is pulled, and when the pulling force is greater than the tensile elastic force of the second return spring 10, the latch 9 moves outward, and the head of the latch 9 leaves the tooth groove of the one-way rack 8a. At this time, the pressing head 4 and the compression portion 5, which have lost their limits, move to the initial position under the action of the elastic force of the first return spring 7, and stop pressing the patient's needle eye position.

[0031] Example 2

[0032] like Figures 5-6 As shown, the hemostatic pressing part also includes a locking member, which includes a latch 9. A one-way rack 8a is provided in the axial direction of one of the connecting rods 8. A transverse through hole 1b and a power transmission cavity 1c are also provided on the support plate 1. The two ends of the transverse through hole 1b intersect with the longitudinal through hole 1a and the power transmission cavity 1c respectively. The latch 9 is sleeved in the transverse through hole 1b. The head of the latch 9 extends into the longitudinal through hole 1a and cooperates with the one-way rack 8a, thereby limiting the connecting rod 8 to only slide in one direction in the longitudinal through hole 1a, thereby limiting the pressing member to only move in one direction. Specifically, the moving direction of the pressing member is limited to moving from a high position to a low position. A first transmission rack is provided at the tail of the latch pin 9, and a second return spring 10 and a rotatable gear 11 are provided in the power transmission chamber 1c. The first transmission rack is meshed with the gear 11, and both ends of the second return spring 10 are pressed against the tail of the latch pin 9 and the inner wall of the power transmission chamber 1c. The second return spring 10 provides a continuous elastic force to keep the head of the latch pin 9 inserted into the tooth groove of the one-way rack 8a in the absence of external force.

[0033] A longitudinal push rod 12 is also provided in the power transmission chamber 1c, the head of the push rod 12 passes through the power transmission chamber 1c and is located above the support plate 1, and a second transmission rack is provided at the tail of the push rod 12, which meshes with the gear 11. When necessary, the push rod 12 is pressed downward, and a thrust opposite to the second reset spring 10 is provided through the conduction of the second transmission rack, the gear 11 and the first transmission rack. When the thrust is greater than the elastic force of the second reset spring 10, the drive pin 9 moves in a direction away from the one-way rack 8a, and the head of the pin 9 leaves the tooth groove of the one-way rack 8a. At this time, the pressing member that loses its limitation moves to the initial position under the action of the elastic force of the first reset spring 7, and stops pressing the patient's needle eye position.

[0034] An elastic buffer layer 6 is disposed at the bottom of the pressing portion 5 . Specifically, the elastic buffer layer 6 may be made of rubber, silicone or foam.

[0035] The working principle of the present invention is: when the infusion is completed and the needle needs to be removed, first the infusion patch is applied so that the middle part of the infusion patch covers the needle eye, and then the hemostatic pressing part is placed at the location of the needle eye, and the pressing piece is located above the patient's needle eye. The supporting foot 3 of the hemostatic pressing part is in direct contact with the patient's skin and supports the entire hemostatic pressing part, and then the strip elastic bands 2 on both sides are passed around the patient's affected area and fixed, and then the needle is removed. After the needle is removed, the pressing piece is immediately pressed downward. Under the action of pressure, the pressing piece moves from a high position to a low position, and the compression part 5 presses the needle eye position through the infusion patch to prevent bleeding at the needle eye or subcutaneous congestion. After the preset time is reached, the pressing is completed, and the gripping portion 9a is pulled outward or the push rod 12 is pressed downward to make the head of the pin 9 leave the tooth groove of the one-way rack 8a. The pressing piece, which has lost its limitation, returns to the high position from the low position under the action of the elastic force of the first return spring 7, stops pressing the patient's needle hole position, and then the intravenous infusion pressing hemostasis device can be removed.

[0036] The above is an exemplary description of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention. The protection scope of the present invention shall be based on the protection scope defined in the claims.
