Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and in particular relates to a venous blood collection pad. Background Technology

[0002] The core function of medical blood collection pads is to improve the safety, hygiene, and patient comfort of blood collection procedures.

[0003] Conventional blood collection pads typically use stacked disposable drapes, which are prone to tipping over and scattering during operation due to movement. Furthermore, the overall height decreases with each use of the disposable drapes, making them inconvenient for medical staff. To address these shortcomings, we propose a new type of venous blood collection pad. Utility Model Content

[0004] The purpose of this invention is to provide a venous blood collection pad to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A venous blood collection pad, comprising: The composite pad consists of an arc-shaped outer shell, an embedding groove formed on the upper surface of the arc-shaped outer shell, and a detachable blood collection pad block that is snapped into the inner wall of the embedding groove. A modular pad assembly, comprising multiple sets of medical-grade pads connected by tear-off points, each set of pads using a non-woven fabric substrate and a double-sided polyethylene antibacterial film composite structure. The blood collection pad fixing structure includes a storage box disposed on the left side of the arc-shaped outer shell, a support frame fixedly installed on the right side of the arc-shaped outer shell, a through groove opened on the left side of the support frame, and a blood collection pad clamping assembly. The storage box includes a box body, an antibacterial compartment inside the box body, a cover plate fixed to the upper surface of the box body by bolts, and a channel between the cover plate and the box body. The blood collection pad clamping assembly includes strip grooves respectively formed on the upper surface of the box and the bottom wall of the through groove, a guide groove formed on the inner wall of the strip groove, a clearance groove formed on the inner wall of the guide groove, a clamping block slidably installed on the inner wall of the strip groove, a guide post fixedly installed on the lower end of the clamping block, and a counterweight block fixedly installed on the lower end of the guide post.

[0006] Preferably, the towel assembly is stored in a spiral roll within the antibacterial compartment of the storage box.

[0007] Preferably, both the slot and the channel allow the pad to pass through.

[0008] Preferably, the drape, when unfolded, completely covers the operating surface of the blood collection pad, with the edge extending to form a contamination-proof coverage area of ​​≥20mm.

[0009] Preferably, the bottom of the arc-shaped outer shell, the storage box, and the support frame are all provided with anti-slip pads.

[0010] The venous blood collection pad of this utility model has the following advantages: This type of venous blood collection pad uses a modular drape with a composite structure of non-woven fabric and antibacterial film, combined with a ≥20mm anti-contamination coverage area to achieve double biological protection. The spiral roll drape is stored in an antibacterial compartment and the blood collection pad clamping component ensures "one drape per person" aseptic operation. The easy-tear design at the break point makes the drape easy to replace, avoiding the tipping problem of traditional stacked drapes. Attached Figure Description

[0019] To better understand the purpose, structure, and function of this utility model, a venous blood collection pad of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, the present invention provides a venous blood collection pad, comprising: a composite pad body, a modular drape assembly, and a blood collection pad fixing structure.

[0021] The composite pad consists of an arc-shaped outer shell 10, an embedding groove on the upper surface of the arc-shaped outer shell 10, and a detachable blood collection pad 11 that is snapped into the inner wall of the embedding groove. The arc-shaped outer shell 10 provides ergonomic support, and the detachable blood collection pad 11 in the embedding groove is easy to clean, disinfect or replace.

[0022] The modular pad assembly consists of multiple sets of medical-grade pads 21 connected by tear-off points 20. Each set of pads 21 uses a composite structure of non-woven fabric substrate and double-sided polyethylene antibacterial film. The medical-grade pads 21 can be quickly separated into individual sheets through tear-off points 20, and the composite structure of non-woven fabric and antibacterial film provides double protection.

[0023] The blood collection pad fixing structure includes a storage box located on the left side of the arc-shaped outer shell 10, a support frame 30 fixedly installed on the right side of the arc-shaped outer shell 10, a through groove opened on the left side of the support frame 30, and a blood collection pad clamping assembly.

[0024] The storage box includes a box body 40, an antibacterial compartment inside the box body 40, a cover plate 41 fixed to the upper surface of the box body 40 by bolts, and a channel between the cover plate 41 and the box body 40. The pad assembly is stored in the antibacterial compartment of the storage box in a spiral roll. The cover plate 41 is fixed to the storage box by bolts to ensure the sterility of the pad 21 stored in the antibacterial compartment.

[0025] Both the slot and the channel allow the pad 21 to pass through. After the pad 21 is unfolded, it completely covers the operating surface of the blood collection pad 11, and the edge extends to form a ≥20mm anti-contamination coverage area. After the pad 21 is unfolded, it covers the operating surface of the blood collection pad 11 and extends ≥20mm to form a sterile operating area, preventing cross-infection. The bottom of the arc-shaped shell 10, the storage box and the support frame 30 are all equipped with anti-slip pads 60. The anti-slip pads 60 prevent the instruments from shifting during operation and ensure the accuracy of blood collection.

[0026] The blood collection pad clamping assembly includes strip grooves respectively formed on the upper surface of the box body 40 and the bottom wall of the through groove, a guide groove formed on the inner wall of the strip groove, an avoidance groove formed on the inner wall of the guide groove, a clamping block 50 slidably installed on the inner wall of the strip groove, a guide post 51 fixedly installed on the lower end of the clamping block 50, and a counterweight block 52 fixedly installed on the lower end of the guide post 51. The spirally rolled antibacterial pad 21 is stored in the antibacterial compartment of the storage box, led out through the channel between the cover plate 41 and the box body 40, and then passes through the through groove of the support frame 30. At this time, the pad 21 will cover the blood collection pad 1. 1. Operational surface: When the device contacts the blood collection table, the counterweight 52 will enter the clearance groove upon contact with the blood collection table, and the guide column 51 will slide up along the guide groove. The clamping block 50 will automatically press the edge of the pad 21 to ensure flatness during use. After blood collection is completed, the device is lifted, and the clamping block 50 slides down along the strip groove under the gravity of the counterweight 52, automatically detaching from the pad 21. After the pad 21 is freed from the restraint of the clamping block 50, a new pad 21 can be pulled out. The used pad 21 can be torn off the contaminated pad 21 along the tear-off easy-tear opening 20, realizing the aseptic operation of "one person, one pad".

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
