Problems solved by technology

[0002] In the process of clinical treatment, it is often necessary to perform venipuncture to draw blood. After the blood is drawn, the patient often needs to use the other hand to press a cotton swab on the local area to stop bleeding for 10 to 15 minutes. Therefore, this method of hemostasis brings a lot of pain to the patient It is very inconvenient for the patient to carry out the next step of examination and treatment immediately, especially in winter, the rolled up clothes are tightly hooped on the arm to hinder the return of venous blood, which is more likely to cause the vein to bleed from the injured part, and the patient's hand is used for a long time , uneven pressing pressure may also cause subcutaneous bleeding

Embodiment 1

[0027] Such as figure 1 As shown, a body surface hemostat, the body surface hemostat includes a limit rod 2 and a fixed piece 1 made of hard PVC material, the limit rod 2 is inserted into the limit hole 3 to form a clamping limit; as figure 2 As shown, the middle part of the fixed sheet 1 is provided with a limiting hole 3, the ventral surface of the fixed sheet 1 is coated with a medical adhesive, the ventral side of the limiting hole 3 is covered with a wound protection layer 4, and the wound protection layer 4 is made of an elastic material. The wound protection layer 4 and the abdominal surface of the fixing sheet 1 are adhered by medical adhesive. Such as image 3 The shown fixed piece 1 is a rectangle with chamfered corners, and the limiting hole 3 is provided with two relative limiting hole protrusions 5, such as Figure 4-5 As shown, the limit rod 2 is provided with eight limit rod annular grooves 6 and two limit rod longitudinal grooves 7 that can cooperate with th...

Embodiment 2

[0032] Such as Figure 6 , 7 As shown, a body surface hemostat, the body surface hemostat includes a fixed piece 11 made of hard PVC material, which is rectangular with chamfers; Coated with medical adhesive, the ventral side of the limiting hole 31 is covered with a wound protection layer 41, the wound protection layer 41 is made of elastic material, and the abdominal surface of the wound protection layer 41 and the fixing sheet 11 is adhered by a medical adhesive; Figure 8-9 As shown, the limit rod 21 is provided with two limit rod annular grooves 61 that can be snap-fitted with the limit hole 31 , and the upper end of the limit rod 21 is provided with a non-slip cap.

[0033] work process:

[0034] Forcibly insert the limiting rod 21 into the limiting hole 31, and select an appropriate annular groove of the limiting rod according to the elasticity of the patient's skin and the condition of the wound surface, so that the annular groove 61 of the limiting rod and the limit...

Abstract

A body surface haemostat is characterized by comprising a rigid fixing piece (1) and a limiting rod (2), a limiting hole (3) is arranged in the middle of the fixing piece (1), the limiting rod(2) can be inserted into the limiting hole (3) to form snapping connection limiting, the ventral surface of the fixing piece (1) is coated with medical adhesive or is provided with a sucker, and the inside surface of the limiting hole (3) is covered with a wound protective layer (4). The body surface haemostat has the advantages that the limiting rod is inserted into the limiting hole and is snapped in the fixing piece to achieve the compression hemostasis on a wound, and accordingly using easiness and safety can be obtained; the limiting rod and the fixing piece are separated, not only the processing easiness is facilitated, but also the fixing piece can be reused, and therefore energy saving and environmental friendliness are obtained; and the limiting rod is provided with two or more limiting rod annular grooves to enable the limiting hole and the limiting rod to form limiting among different limiting rod annular grooves, so that a user can apply pressing forces in different strength according to the wound situation of a patient.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a disposable blood device. technical background: [0002] In the process of clinical treatment, it is often necessary to perform venipuncture to draw blood. After the blood is drawn, the patient often needs to use the other hand to press a cotton swab on the local area to stop bleeding for 10 to 15 minutes. Therefore, this method of hemostasis has brought great inconvenience to the patient. It is very inconvenient for the patient to carry out the next step of examination and treatment immediately, especially in winter, the rolled up clothes are tightly hooped on the arm to hinder the return of venous blood, which is more likely to cause the vein to bleed from the injured part, and the patient's hand is used for a long time , Uneven pressing pressure may also cause subcutaneous bleeding. Invention content: [0003] The object of the present invention is to provide a more convenient and safe...
